+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at https://www.st.com/content/st_com/en/contact-us.html. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

+## Contributing guide
+This document serves as a checklist before contributing to this repository.
+It includes links to read up on if topics are unclear to you.
+
+This guide mainly focuses on the proper use of Git.
+
+### 1. Before opening an issue
+To report a bug/request please file an issue in the right repository
+(example for [stm32l1xx_hal_driver](https://github.com/STMicroelectronics/stm32l1xx_hal_driver/issues/new/choose)).
+But check the following boxes before posting an issue:
+
+- [ ] `Make sure you are using the latest commit (major releases are Tagged, but corrections are available as new commits).`
+- [ ] `Make sure your issue is a question/feedback/suggestions RELATED TO the software provided in this repo.` Otherwise, it should be discussed on the [ST Community/STM32 MCUs forum](https://community.st.com/s/group/0F90X000000AXsASAW/stm32-mcus).
+- [ ] `Make sure your issue is not already reported/fixed on GitHub or discussed on a previous Issue.` Please refer to this [dashboard](https://github.com/orgs/STMicroelectronics/projects/2) for the list of issues and pull-requests. Do not forget to browse into the **closed** issues.
+
+
+### 2. Posting the issue
+When you have checked the previous boxes. You will find two templates Issues (Bug Report or Other Issue) available in the **Issues** tab of the repo
+
+### 3. Pull Requests
+For the moment, the Pull Request feature is not deployed. STMicrolectronics is working on a Contributor License Agreement procedure

+  * @brief  Structure definition of ADC and regular group initialization 
+  * @note   Parameters of this structure are shared within 2 scopes:
+  *          - Scope entire ADC (affects regular and injected groups): ClockPrescaler, Resolution, ScanConvMode, DataAlign, ScanConvMode, EOCSelection, LowPowerAutoWait, LowPowerAutoPowerOff, ChannelsBank.
+  *          - Scope regular group: ContinuousConvMode, NbrOfConversion, DiscontinuousConvMode, NbrOfDiscConversion, ExternalTrigConvEdge, ExternalTrigConv.
+  * @note   The setting of these parameters with function HAL_ADC_Init() is conditioned to ADC state.
+  *         ADC state can be either:
+  *          - For all parameters: ADC disabled
+  *          - For all parameters except 'Resolution', 'ScanConvMode', 'LowPowerAutoWait', 'LowPowerAutoPowerOff', 'DiscontinuousConvMode', 'NbrOfDiscConversion' : ADC enabled without conversion on going on regular group.
+  *          - For parameters 'ExternalTrigConv' and 'ExternalTrigConvEdge': ADC enabled, even with conversion on going.
+  *         If ADC is not in the appropriate state to modify some parameters, these parameters setting is bypassed
+  *         without error reporting (as it can be the expected behaviour in case of intended action to update another parameter (which fullfills the ADC state condition) on the fly).

+/** @brief Reset the Handle's State field.
+  * @param __HANDLE__: specifies the Peripheral Handle.
+  * @note  This macro can be used for the following purpose:
+  *          - When the Handle is declared as local variable; before passing it as parameter
+  *            to HAL_PPP_Init() for the first time, it is mandatory to use this macro
+  *            to set to 0 the Handle's "State" field.
+  *            Otherwise, "State" field may have any random value and the first time the function
+  *            HAL_PPP_Init() is called, the low level hardware initialization will be missed
+  *            (i.e. HAL_PPP_MspInit() will not be executed).
+  *          - When there is a need to reconfigure the low level hardware: instead of calling
+  *            HAL_PPP_DeInit() then HAL_PPP_Init(), user can make a call to this macro then HAL_PPP_Init().
+  *            In this later function, when the Handle's "State" field is set to 0, it will execute the function
+  *            HAL_PPP_MspInit() which will reconfigure the low level hardware.
+  * @retval None

+  *           helper macro @ref __LL_ADC_CHANNEL_TO_DECIMAL_NB().
+  *           Then the selected literal LL_ADC_CHANNEL_x can be used
+  *           as parameter for another function.
+  *         - To get the channel number in decimal format:

+  * @brief  Get ADC analog watchdog monitored channel.
+  * @note   Usage of the returned channel number:
+  *         - To reinject this channel into another function LL_ADC_xxx:
+  *           the returned channel number is only partly formatted on definition
+  *           of literals LL_ADC_CHANNEL_x. Therefore, it has to be compared
+  *           with parts of literals LL_ADC_CHANNEL_x or using
+  *           helper macro @ref __LL_ADC_CHANNEL_TO_DECIMAL_NB().
+  *           Then the selected literal LL_ADC_CHANNEL_x can be used
+  *           as parameter for another function.
+  *         - To get the channel number in decimal format:
+  *           process the returned value with the helper macro
+  *           @ref __LL_ADC_CHANNEL_TO_DECIMAL_NB().
+  *           Applicable only when the analog watchdog is set to monitor
+  *           one channel.
+  * @note   On this STM32 serie, there is only 1 kind of analog watchdog
+  *         instance:
+  *         - AWD standard (instance AWD1):
+  *           - channels monitored: can monitor 1 channel or all channels.
+  *           - groups monitored: ADC groups regular and-or injected.
+  *           - resolution: resolution is not limited (corresponds to
+  *             ADC resolution configured).

+                      ##### RCC Limitations #####
+  ==============================================================================
+    [..]
+      A delay between an RCC peripheral clock enable and the effective peripheral
+      enabling should be taken into account in order to manage the peripheral read/write
+      from/to registers.
+      (+) This delay depends on the peripheral mapping.
+        (++) AHB & APB peripherals, 1 dummy read is necessary
+
+    [..]
+      Workarounds:
+      (#) For AHB & APB peripherals, a dummy read to the peripheral register has been
+          inserted in each LL_{BUS}_GRP{x}_EnableClock() function.

+  ==============================================================================
+                     ##### How to use this driver #####
+  ==============================================================================
+    [..]
+    The LL CORTEX driver contains a set of generic APIs that can be
+    used by user:
+      (+) SYSTICK configuration used by @ref LL_mDelay and @ref LL_Init1msTick
+          functions
+      (+) Low power mode configuration (SCB register of Cortex-MCU)
+      (+) MPU API to configure and enable regions
+      (+) API to access to MCU info (CPUID register)
+      (+) API to enable fault handler (SHCSR accesses)
+

-# stm32l1xx_hal_driver
-Provides the STM32Cube MCU Component "hal_driver" of the STM32L1 series.
+# STM32CubeL1 HAL Driver MCU Component
+
+## Overview
+
+**STM32Cube** is an STMicroelectronics original initiative to ease the developers life by reducing efforts, time and cost.
+
+**STM32Cube** covers the overall STM32 products portfolio. It includes a comprehensive embedded software platform, delivered for each STM32 series.
+   * The CMSIS modules (core and device) corresponding to the ARM(tm) core implemented in this STM32 product
+   * The STM32 HAL-LL drivers : an abstraction drivers layer, the API ensuring maximized portability across the STM32 portfolio
+   * The BSP Drivers of each evaluation or demonstration board provided by this STM32 series
+   * A consistent set of middlewares components such as RTOS, USB, FatFS, Graphics, STM32_TouchSensing_Library ...
+   * A full set of software projects (basic examples, applications or demonstrations) for each board provided by this STM32 series
+
+Two models of publication are proposed for the STM32Cube embedded software:
+   * The monolithic **MCU Package** : all STM32Cube software modules of one STM32 series are present (Drivers, Middlewares, Projects, Utilities) in the repo (usual name **STM32Cubexx**, xx corresponding to the STM32 series)
+   * The **MCU component** : progressively from November 2019, each STM32Cube software module being part of the STM32Cube MCU Package, will be delivered as an individual repo, allowing the user to select and get only the required software functions.
+
+## Description
+
+This **stm32l1xx_hal_driver** MCU component repo is one element of the STM32CubeL1 MCU embedded software package, providing the **HAL-LL Drivers** part.

+<h1 id="purpose">Purpose</h1>
+<p>The STM32Cube HAL and LL, an STM32 abstraction layer embedded software, ensure maximized portability across STM32 portfolio.</p>
+<p>The portable APIs layer provides a generic, multi instanced and simple set of APIs to interact with the upper layer (application, libraries and stacks). It is composed of native and extended APIs set. It is directly built around a generic architecture and allows the build-upon layers, like the middleware layer, to implement its functions without knowing in-depth the used STM32 device. This improves the library code reusability and guarantees an easy portability on other devices and STM32 families.</p>
+<p>The Low Layer (LL) drivers are part of the STM32Cube firmware HAL that provides a basic set of optimized and one shot services. The Low layer drivers, contrary to the HAL ones are not fully portable across the STM32 families; the availability of some functions depends on the physical availability of the relative features on the product. The Low Layer (LL) drivers are designed to offer the following features:</p>
+<ul>
+<li>New set of inline functions for direct and atomic register access</li>
+<li>One-shot operations that can be used by the HAL drivers or from application level</li>
+<li>Full independence from HAL and standalone usage (without HAL drivers)</li>
+<li>Full features coverage of all the supported peripherals</li>
+</ul>

+   [..]  This section provides functions allowing to:

+          configuration. It initializes the source of time base also when timeout
+          is needed and the backup domain when enabled.
+      (+) De-initialize common part of the HAL.
+      (+) Configure the time base source to have 1ms time base with a dedicated
+          Tick interrupt priority.
+        (++) SysTick timer is used by default as source of time base, but user
+             can eventually implement his proper time base source (a general purpose
+             timer for example or other time source), keeping in mind that Time base
+             duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
+             handled in milliseconds basis.
+        (++) Time base configuration function (HAL_InitTick ()) is called automatically
+             at the beginning of the program after reset by HAL_Init() or at any time
+             when clock is configured, by HAL_RCC_ClockConfig().
+        (++) Source of time base is configured  to generate interrupts at regular
+             time intervals. Care must be taken if HAL_Delay() is called from a
+             peripheral ISR process, the Tick interrupt line must have higher priority
+            (numerically lower) than the peripheral interrupt. Otherwise the caller
+            ISR process will be blocked.

+
+    (#) Enable the ADC interface
+      (++) As prerequisite, ADC clock must be configured at RCC top level.
+           Caution: On STM32L1, ADC clock frequency max is 16MHz (refer
+                    to device datasheet).
+                    Therefore, ADC clock prescaler must be configured in 
+                    function of ADC clock source frequency to remain below
+                    this maximum frequency.
+
+        (++) Two clock settings are mandatory: 
+             (+++) ADC clock (core clock).
+             (+++) ADC clock (conversions clock).
+                   Only one possible clock source: derived from HSI RC 16MHz oscillator
+                   (HSI). 
+                   ADC is connected directly to HSI RC 16MHz oscillator.
+                   Therefore, RCC PLL setting has no impact on ADC.
+                   PLL can be disabled (".PLL.PLLState = RCC_PLL_NONE") or 
+                   enabled with HSI16 as clock source
+                   (".PLL.PLLSource = RCC_PLLSOURCE_HSI") to be used as device 
+                   main clock source SYSCLK.
+                   The only mandatory setting is ".HSIState = RCC_HSI_ON"
+
+             (+++) Example:
+                   Into HAL_ADC_MspInit() (recommended code location) or with

+               (+++) RCC_OscInitStructure.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT;
+               (+++) RCC_OscInitStructure.PLL.PLLState = RCC_PLL_NONE;
+               (+++) RCC_OscInitStructure.PLL.PLLSource = ...

+         (++) Configure the NVIC for ADC
+              using function HAL_NVIC_EnableIRQ(ADCx_IRQn)
+         (++) Insert the ADC interruption handler function HAL_ADC_IRQHandler()

+    =============================================
+    [..]
+
+     The compilation flag USE_HAL_ADC_REGISTER_CALLBACKS, when set to 1,
+     allows the user to configure dynamically the driver callbacks.
+     Use Functions @ref HAL_ADC_RegisterCallback()
+     to register an interrupt callback.
+    [..]
+
+     Function @ref HAL_ADC_RegisterCallback() allows to register following callbacks:
+       (+) ConvCpltCallback               : ADC conversion complete callback
+       (+) ConvHalfCpltCallback           : ADC conversion DMA half-transfer callback
+       (+) LevelOutOfWindowCallback       : ADC analog watchdog 1 callback
+       (+) ErrorCallback                  : ADC error callback
+       (+) InjectedConvCpltCallback       : ADC group injected conversion complete callback
+       (+) MspInitCallback                : ADC Msp Init callback
+       (+) MspDeInitCallback              : ADC Msp DeInit callback
+     This function takes as parameters the HAL peripheral handle, the Callback ID
+     and a pointer to the user callback function.
+    [..]
+
+     Use function @ref HAL_ADC_UnRegisterCallback to reset a callback to the default
+     weak function.
+    [..]
+
+     @ref HAL_ADC_UnRegisterCallback takes as parameters the HAL peripheral handle,
+     and the Callback ID.
+     This function allows to reset following callbacks:
+       (+) ConvCpltCallback               : ADC conversion complete callback
+       (+) ConvHalfCpltCallback           : ADC conversion DMA half-transfer callback
+       (+) LevelOutOfWindowCallback       : ADC analog watchdog 1 callback
+       (+) ErrorCallback                  : ADC error callback
+       (+) InjectedConvCpltCallback       : ADC group injected conversion complete callback
+       (+) MspInitCallback                : ADC Msp Init callback
+       (+) MspDeInitCallback              : ADC Msp DeInit callback
+     [..]
+
+     By default, after the @ref HAL_ADC_Init() and when the state is @ref HAL_ADC_STATE_RESET
+     all callbacks are set to the corresponding weak functions:
+     examples @ref HAL_ADC_ConvCpltCallback(), @ref HAL_ADC_ErrorCallback().
+     Exception done for MspInit and MspDeInit functions that are
+     reset to the legacy weak functions in the @ref HAL_ADC_Init()/ @ref HAL_ADC_DeInit() only when
+     these callbacks are null (not registered beforehand).
+    [..]
+
+     If MspInit or MspDeInit are not null, the @ref HAL_ADC_Init()/ @ref HAL_ADC_DeInit()
+     keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
+     [..]
+
+     Callbacks can be registered/unregistered in @ref HAL_ADC_STATE_READY state only.
+     Exception done MspInit/MspDeInit functions that can be registered/unregistered
+     in @ref HAL_ADC_STATE_READY or @ref HAL_ADC_STATE_RESET state,
+     thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
+    [..]
+
+     Then, the user first registers the MspInit/MspDeInit user callbacks
+     using @ref HAL_ADC_RegisterCallback() before calling @ref HAL_ADC_DeInit()
+     or @ref HAL_ADC_Init() function.
+     [..]
+
+     When the compilation flag USE_HAL_ADC_REGISTER_CALLBACKS is set to 0 or
+     not defined, the callback registration feature is not available and all callbacks
+     are set to the corresponding weak functions.

+  *         See commented example code below that can be copied and uncommented

+  *         be used to reconfigure some parameters of ADC_InitTypeDef  
+  *         structure on the fly, without modifying MSP configuration. If ADC

+  *         before HAL_ADC_Init().

+      The STM32L1xx device family integrates 2 analog comparators COMP1 and 
+      COMP2:
+      (#) The non inverting input and inverting input can be set to GPIO pins.
+          HAL COMP driver configures the Routing Interface (RI) to connect the
+          selected I/O pins to comparator input.
+          Caution: Comparator COMP1 and ADC cannot be used at the same time as 
+          ADC since they share the ADC switch matrix: COMP1 non-inverting 
+          input is routed through ADC switch matrix. Except if ADC is intended 
+          to measure voltage on COMP1 non-inverting input: it can be performed 
+          on ADC channel VCOMP.
+
+      (#) The COMP output is available using HAL_COMP_GetOutputLevel().
+
+      (#) The COMP output can be redirected to embedded timers (TIM2, TIM3, 
+          TIM4, TIM10).
+          COMP output cannot be redirected to any I/O pin.
+
+      (#) The comparators COMP1 and COMP2 can be combined in window mode. 
+          In this mode, COMP2 non inverting input is used as common 
+          non-inverting input.
+  
+      (#) The 2 comparators have interrupt capability with wake-up

+          (++) COMP2 is internally connected to EXTI Line 22
+
+          From the corresponding IRQ handler, the right interrupt source can be retrieved with the

+
+            ##### How to use this driver #####
+================================================================================
+  [..]
+      This driver provides functions to configure and program the Comparators of all STM32L1xx devices.
+
+      To use the comparator, perform the following steps:
+  
+      (#)  Initialize the COMP low level resources by implementing the HAL_COMP_MspInit().
+      (++) Configure the comparator input I/O pin using HAL_GPIO_Init():
+           - For all inputs: I/O pin in analog mode (Schmitt trigger disabled)
+           - Possible alternate configuration, for non-inverting inputs of comparator 2: I/O pin in floating mode (Schmitt trigger enabled).
+           It is recommended to use analog configuration to avoid any overconsumption around VDD/2.
+      (++) Enable COMP Peripheral clock using macro __HAL_RCC_COMP_CLK_ENABLE()
+      (++) If required enable the COMP interrupt (EXTI line Interrupt): enable
+           the comparator interrupt vector using HAL_NVIC_EnableIRQ(COMP_IRQn)
+           and HAL_NVIC_SetPriority(COMP_IRQn, xxx, xxx) functions.
+  
+      (#) Configure the comparator using HAL_COMP_Init() function:
+      (++) Select the inverting input (COMP2 only)
+      (++) Select the non-inverting input
+      (++) Select the output redirection to timers (COMP2 only)
+      (++) Select the speed mode (COMP2 only)
+      (++) Select the window mode (related to COMP1 and COMP2, but selected 
+           by COMP2 only)
+      (++) Select the pull-up/down resistors on non-inverting input (COMP1 only)
+
+      (#) Enable the comparator using HAL_COMP_Start() or HAL_COMP_Start_IT() 
+          function
+    
+      (#) If needed, use HAL_COMP_GetOutputLevel() or HAL_COMP_TriggerCallback()
+          functions to manage comparator actions (output level or events)
+
+      (#) Disable the comparator using HAL_COMP_Stop() or HAL_COMP_Stop_IT() 
+          function
+
+      (#) De-initialize the comparator using HAL_COMP_DeInit() function
+
+    *** Callback registration ***
+    =============================================
+    [..]
+
+     The compilation flag USE_HAL_COMP_REGISTER_CALLBACKS, when set to 1,
+     allows the user to configure dynamically the driver callbacks.
+     Use Functions @ref HAL_COMP_RegisterCallback()
+     to register an interrupt callback.
+    [..]
+
+     Function @ref HAL_COMP_RegisterCallback() allows to register following callbacks:
+       (+) TriggerCallback       : callback for COMP trigger.
+       (+) MspInitCallback       : callback for Msp Init.
+       (+) MspDeInitCallback     : callback for Msp DeInit.
+     This function takes as parameters the HAL peripheral handle, the Callback ID
+     and a pointer to the user callback function.
+    [..]
+
+     Use function @ref HAL_COMP_UnRegisterCallback to reset a callback to the default
+     weak function.
+    [..]
+
+     @ref HAL_COMP_UnRegisterCallback takes as parameters the HAL peripheral handle,
+     and the Callback ID.
+     This function allows to reset following callbacks:
+       (+) TriggerCallback       : callback for COMP trigger.
+       (+) MspInitCallback       : callback for Msp Init.
+       (+) MspDeInitCallback     : callback for Msp DeInit.
+     [..]
+
+     By default, after the @ref HAL_COMP_Init() and when the state is @ref HAL_COMP_STATE_RESET
+     all callbacks are set to the corresponding weak functions:
+     example @ref HAL_COMP_TriggerCallback().
+     Exception done for MspInit and MspDeInit functions that are
+     reset to the legacy weak functions in the @ref HAL_COMP_Init()/ @ref HAL_COMP_DeInit() only when
+     these callbacks are null (not registered beforehand).
+    [..]
+
+     If MspInit or MspDeInit are not null, the @ref HAL_COMP_Init()/ @ref HAL_COMP_DeInit()
+     keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
+     [..]
+
+     Callbacks can be registered/unregistered in @ref HAL_COMP_STATE_READY state only.
+     Exception done MspInit/MspDeInit functions that can be registered/unregistered
+     in @ref HAL_COMP_STATE_READY or @ref HAL_COMP_STATE_RESET state,
+     thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
+    [..]
+
+     Then, the user first registers the MspInit/MspDeInit user callbacks
+     using @ref HAL_COMP_RegisterCallback() before calling @ref HAL_COMP_DeInit()
+     or @ref HAL_COMP_Init() function.
+     [..]
+
+     When the compilation flag USE_HAL_COMP_REGISTER_CALLBACKS is set to 0 or
+     not defined, the callback registration feature is not available and all callbacks
+     are set to the corresponding weak functions.

+  *
+  *          This file provides firmware functions to manage the following
+  *          functionalities of the CORTEX:
+  *           + Initialization and de-initialization functions

+  ==============================================================================
+
+    [..]  
+    *** How to configure Interrupts using Cortex HAL driver ***
+    ===========================================================
+    [..]     
+    This section provide functions allowing to configure the NVIC interrupts (IRQ).
+    The Cortex-M3 exceptions are managed by CMSIS functions.
+   
+    (#) Configure the NVIC Priority Grouping using HAL_NVIC_SetPriorityGrouping() function
+
+     (#)  Configure the priority of the selected IRQ Channels using HAL_NVIC_SetPriority() 
+
+     (#)  Enable the selected IRQ Channels using HAL_NVIC_EnableIRQ() 
+      
+
+     -@- When the NVIC_PRIORITYGROUP_0 is selected, IRQ pre-emption is no more possible. 
+         The pending IRQ priority will be managed only by the sub priority.
+   
+     -@- IRQ priority order (sorted by highest to lowest priority):
+        (+@) Lowest pre-emption priority
+        (+@) Lowest sub priority
+        (+@) Lowest hardware priority (IRQ number)
+ 
+    [..]  
+    *** How to configure Systick using Cortex HAL driver ***
+    ========================================================
+    [..]
+    Setup SysTick Timer for 1 msec interrupts.
+           
+   (+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which
+       is a CMSIS function that:
+        (++) Configures the SysTick Reload register with value passed as function parameter.
+        (++) Configures the SysTick IRQ priority to the lowest value (0x0F).
+        (++) Resets the SysTick Counter register.
+        (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
+        (++) Enables the SysTick Interrupt.
+        (++) Starts the SysTick Counter.
+    
+   (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
+       __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
+       HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
+       inside the stm32l1xx_hal_cortex.h file.
+
+   (+) You can change the SysTick IRQ priority by calling the
+       HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function 
+       call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
+
+   (+) To adjust the SysTick time base, use the following formula:
+                            
+       Reload Value = SysTick Counter Clock (Hz) x  Desired Time base (s)
+       (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
+       (++) Reload Value should not exceed 0xFFFFFF

+  ==============================================================================
+    [..]
+      The CRYP HAL driver can be used as follows:
+
+      (#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit():
+         (##) Enable the CRYP interface clock using __HAL_RCC_CRYP_CLK_ENABLE()
+         (##) In case of using interrupts (e.g. HAL_CRYP_AESECB_Encrypt_IT())
+             (+) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority()
+             (+) Enable the CRYP IRQ handler using HAL_NVIC_EnableIRQ()
+             (+) In CRYP IRQ handler, call HAL_CRYP_IRQHandler()
+         (##) In case of using DMA to control data transfer (e.g. HAL_CRYP_AESECB_Encrypt_DMA())
+             (+) Enable the DMA2 interface clock using 
+                 (++) __HAL_RCC_DMA2_CLK_ENABLE()
+             (+) Configure and enable two DMA Channels one for managing data transfer from
+                 memory to peripheral (input channel) and another channel for managing data
+                 transfer from peripheral to memory (output channel)
+             (+) Associate the initialized DMA handle to the CRYP DMA handle
+                 using  __HAL_LINKDMA()
+             (+) Configure the priority and enable the NVIC for the transfer complete
+                 interrupt on the two DMA Streams. The output stream should have higher
+                 priority than the input stream.
+                 (++) HAL_NVIC_SetPriority()
+                 (++) HAL_NVIC_EnableIRQ()
+    
+      (#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures mainly:
+         (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit
+         (##) The encryption/decryption key.
+         (##) The initialization vector (counter). It is not used ECB mode.
+    
+      (#)Three processing (encryption/decryption) functions are available:
+         (##) Polling mode: encryption and decryption APIs are blocking functions
+              i.e. they process the data and wait till the processing is finished
+              e.g. HAL_CRYP_AESCBC_Encrypt()
+         (##) Interrupt mode: encryption and decryption APIs are not blocking functions
+              i.e. they process the data under interrupt
+              e.g. HAL_CRYP_AESCBC_Encrypt_IT()
+         (##) DMA mode: encryption and decryption APIs are not blocking functions
+              i.e. the data transfer is ensured by DMA
+              e.g. HAL_CRYP_AESCBC_Encrypt_DMA()
+    
+      (#)When the processing function is called for the first time after HAL_CRYP_Init()
+         the CRYP peripheral is initialized and processes the buffer in input.
+         At second call, the processing function performs an append of the already
+         processed buffer.
+         When a new data block is to be processed, call HAL_CRYP_Init() then the
+         processing function.
+         
+      (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.

+                      ##### DAC Peripheral features #####
+  ==============================================================================
+    [..]
+      *** DAC Channels ***
+      ====================
+    [..]
+    STM32L1 devices integrate two 12-bit Digital Analog Converters
+
+    The 2 converters (i.e. channel1 & channel2)
+    can be used independently or simultaneously (dual mode):
+      (#) DAC channel1 with DAC_OUT1 (PA4) as output or connected to on-chip
+          peripherals (ex. timers).
+      (#) DAC channel2 with DAC_OUT2 (PA5) as output or connected to on-chip
+          peripherals (ex. timers).
+
+      *** DAC Triggers ***
+      ====================
+    [..]
+    Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE
+    and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
+    [..]
+    Digital to Analog conversion can be triggered by:
+      (#) External event: EXTI Line 9 (any GPIOx_PIN_9) using DAC_TRIGGER_EXT_IT9.
+          The used pin (GPIOx_PIN_9) must be configured in input mode.
+
+      (#) Timers TRGO: TIM2, TIM4, TIM6, TIM7, TIM9
+          (DAC_TRIGGER_T2_TRGO, DAC_TRIGGER_T4_TRGO...)
+
+      (#) Software using DAC_TRIGGER_SOFTWARE
+
+      *** DAC Buffer mode feature ***
+      ===============================
+      [..]
+      Each DAC channel integrates an output buffer that can be used to
+      reduce the output impedance, and to drive external loads directly
+      without having to add an external operational amplifier.
+      To enable, the output buffer use
+      sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE;
+      [..]
+      (@) Refer to the device datasheet for more details about output
+          impedance value with and without output buffer.
+
+      *** DAC connect feature ***
+      ===============================
+      [..]
+      Each DAC channel can be connected internally.
+      To connect, use
+      sConfig.DAC_ConnectOnChipPeripheral = DAC_CHIPCONNECT_ENABLE;
+
+      *** GPIO configurations guidelines ***
+      =====================
+      [..]
+      When a DAC channel is used (ex channel1 on PA4) and the other is not
+      (ex channel2 on PA5 is configured in Analog and disabled).
+      Channel1 may disturb channel2 as coupling effect.
+      Note that there is no coupling on channel2 as soon as channel2 is turned on.
+      Coupling on adjacent channel could be avoided as follows:
+      when unused PA5 is configured as INPUT PULL-UP or DOWN.
+      PA5 is configured in ANALOG just before it is turned on.
+
+       *** DAC wave generation feature ***
+       ===================================
+       [..]
+       Both DAC channels can be used to generate
+         (#) Noise wave
+         (#) Triangle wave
+
+       *** DAC data format ***
+       =======================
+       [..]
+       The DAC data format can be:
+         (#) 8-bit right alignment using DAC_ALIGN_8B_R
+         (#) 12-bit left alignment using DAC_ALIGN_12B_L
+         (#) 12-bit right alignment using DAC_ALIGN_12B_R
+
+       *** DAC data value to voltage correspondence ***
+       ================================================
+       [..]
+       The analog output voltage on each DAC channel pin is determined
+       by the following equation:
+       [..]
+       DAC_OUTx = VREF+ * DOR / 4095
+       (+) with  DOR is the Data Output Register
+       [..]
+          VEF+ is the input voltage reference (refer to the device datasheet)
+       [..]
+        e.g. To set DAC_OUT1 to 0.7V, use
+       (+) Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
+
+       *** DMA requests ***
+       =====================
+       [..]
+       A DMA1 request can be generated when an external trigger (but not a software trigger)
+       occurs if DMA1 requests are enabled using HAL_DAC_Start_DMA().
+       DMA1 requests are mapped as following:
+      (#) DAC channel1 mapped on DMA1 channel2
+      (#) DAC channel2 mapped on DMA1 channel3
+
+     [..]
+    (@) For Dual mode and specific signal (Triangle and noise) generation please
+        refer to Extended Features Driver description
+
+                      ##### How to use this driver #####
+  ==============================================================================
+    [..]
+      (+) DAC APB clock must be enabled to get write access to DAC
+          registers using HAL_DAC_Init()
+      (+) Configure DAC_OUTx (DAC_OUT1: PA4, DAC_OUT2: PA5) in analog mode.
+      (+) Configure the DAC channel using HAL_DAC_ConfigChannel() function.
+      (+) Enable the DAC channel using HAL_DAC_Start() or HAL_DAC_Start_DMA() functions.
+
+
+     *** Polling mode IO operation ***
+     =================================
+     [..]
+       (+) Start the DAC peripheral using HAL_DAC_Start()
+       (+) To read the DAC last data output value, use the HAL_DAC_GetValue() function.
+       (+) Stop the DAC peripheral using HAL_DAC_Stop()
+
+     *** DMA mode IO operation ***
+     ==============================
+     [..]
+       (+) Start the DAC peripheral using HAL_DAC_Start_DMA(), at this stage the user specify the length
+           of data to be transferred at each end of conversion
+           First issued trigger will start the conversion of the value previously set by HAL_DAC_SetValue().
+       (+) At the middle of data transfer HAL_DAC_ConvHalfCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2()
+           function is executed and user can add his own code by customization of function pointer
+           HAL_DAC_ConvHalfCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2()
+       (+) At The end of data transfer HAL_DAC_ConvCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2()
+           function is executed and user can add his own code by customization of function pointer
+           HAL_DAC_ConvCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2()
+       (+) In case of transfer Error, HAL_DAC_ErrorCallbackCh1() function is executed and user can
+            add his own code by customization of function pointer HAL_DAC_ErrorCallbackCh1
+       (+) In case of DMA underrun, DAC interruption triggers and execute internal function HAL_DAC_IRQHandler.
+           HAL_DAC_DMAUnderrunCallbackCh1() or HAL_DACEx_DMAUnderrunCallbackCh2()

+    *** Callback registration ***
+    =============================================
+    [..]
+      The compilation define  USE_HAL_DAC_REGISTER_CALLBACKS when set to 1
+      allows the user to configure dynamically the driver callbacks.
+
+    Use Functions @ref HAL_DAC_RegisterCallback() to register a user callback,
+      it allows to register following callbacks:
+      (+) ConvCpltCallbackCh1     : callback when a half transfer is completed on Ch1.
+      (+) ConvHalfCpltCallbackCh1 : callback when a transfer is completed on Ch1.
+      (+) ErrorCallbackCh1        : callback when an error occurs on Ch1.
+      (+) DMAUnderrunCallbackCh1  : callback when an underrun error occurs on Ch1.
+      (+) ConvCpltCallbackCh2     : callback when a half transfer is completed on Ch2.
+      (+) ConvHalfCpltCallbackCh2 : callback when a transfer is completed on Ch2.
+      (+) ErrorCallbackCh2        : callback when an error occurs on Ch2.
+      (+) DMAUnderrunCallbackCh2  : callback when an underrun error occurs on Ch2.
+      (+) MspInitCallback         : DAC MspInit.
+      (+) MspDeInitCallback       : DAC MspdeInit.
+      This function takes as parameters the HAL peripheral handle, the Callback ID
+      and a pointer to the user callback function.
+
+    Use function @ref HAL_DAC_UnRegisterCallback() to reset a callback to the default
+      weak (surcharged) function. It allows to reset following callbacks:
+      (+) ConvCpltCallbackCh1     : callback when a half transfer is completed on Ch1.
+      (+) ConvHalfCpltCallbackCh1 : callback when a transfer is completed on Ch1.
+      (+) ErrorCallbackCh1        : callback when an error occurs on Ch1.
+      (+) DMAUnderrunCallbackCh1  : callback when an underrun error occurs on Ch1.
+      (+) ConvCpltCallbackCh2     : callback when a half transfer is completed on Ch2.
+      (+) ConvHalfCpltCallbackCh2 : callback when a transfer is completed on Ch2.
+      (+) ErrorCallbackCh2        : callback when an error occurs on Ch2.
+      (+) DMAUnderrunCallbackCh2  : callback when an underrun error occurs on Ch2.
+      (+) MspInitCallback         : DAC MspInit.
+      (+) MspDeInitCallback       : DAC MspdeInit.
+      (+) All Callbacks
+      This function) takes as parameters the HAL peripheral handle and the Callback ID.
+
+      By default, after the @ref HAL_DAC_Init and if the state is HAL_DAC_STATE_RESET
+      all callbacks are reset to the corresponding legacy weak (surcharged) functions.
+      Exception done for MspInit and MspDeInit callbacks that are respectively
+      reset to the legacy weak (surcharged) functions in the @ref HAL_DAC_Init
+      and @ref  HAL_DAC_DeInit only when these callbacks are null (not registered beforehand).
+      If not, MspInit or MspDeInit are not null, the @ref HAL_DAC_Init and @ref HAL_DAC_DeInit
+      keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
+
+      Callbacks can be registered/unregistered in READY state only.
+      Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
+      in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
+      during the Init/DeInit.
+      In that case first register the MspInit/MspDeInit user callbacks
+      using @ref HAL_DAC_RegisterCallback before calling @ref HAL_DAC_DeInit
+      or @ref HAL_DAC_Init function.
+
+      When The compilation define USE_HAL_DAC_REGISTER_CALLBACKS is set to 0 or
+      not defined, the callback registering feature is not available
+      and weak (surcharged) callbacks are used.

+  ==============================================================================
+  [..]
+   (#) Enable and configure the peripheral to be connected to the DMA Channel
+       (except for internal SRAM / FLASH memories: no initialization is
+       necessary). Please refer to the Reference manual for connection between peripherals
+       and DMA requests.
+
+   (#) For a given Channel, program the required configuration through the following parameters:
+       Channel request, Transfer Direction, Source and Destination data formats,
+       Circular or Normal mode, Channel Priority level, Source and Destination Increment mode
+       using HAL_DMA_Init() function.
+
+   (#) Use HAL_DMA_GetState() function to return the DMA state and HAL_DMA_GetError() in case of error
+       detection.
+
+   (#) Use HAL_DMA_Abort() function to abort the current transfer
+
+     -@-   In Memory-to-Memory transfer mode, Circular mode is not allowed.
+     *** Polling mode IO operation ***
+     =================================
+     [..]
+       (+) Use HAL_DMA_Start() to start DMA transfer after the configuration of Source
+           address and destination address and the Length of data to be transferred
+       (+) Use HAL_DMA_PollForTransfer() to poll for the end of current transfer, in this
+           case a fixed Timeout can be configured by User depending from his application.
+
+     *** Interrupt mode IO operation ***
+     ===================================
+     [..]
+       (+) Configure the DMA interrupt priority using HAL_NVIC_SetPriority()
+       (+) Enable the DMA IRQ handler using HAL_NVIC_EnableIRQ()
+       (+) Use HAL_DMA_Start_IT() to start DMA transfer after the configuration of
+           Source address and destination address and the Length of data to be transferred.
+           In this case the DMA interrupt is configured
+       (+) Use HAL_DMA_IRQHandler() called under DMA_IRQHandler() Interrupt subroutine
+       (+) At the end of data transfer HAL_DMA_IRQHandler() function is executed and user can
+              add his own function to register callbacks with HAL_DMA_RegisterCallback().
+
+     *** DMA HAL driver macros list ***
+     =============================================
+     [..]
+       Below the list of macros in DMA HAL driver.
+
+       (+) __HAL_DMA_ENABLE: Enable the specified DMA Channel.
+       (+) __HAL_DMA_DISABLE: Disable the specified DMA Channel.
+       (+) __HAL_DMA_GET_FLAG: Get the DMA Channel pending flags.

+  ==============================================================================
+                        ##### FLASH peripheral features #####
+  ==============================================================================
+  [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses 
+       to the Flash memory. It implements the erase and program Flash memory operations 
+       and the read and write protection mechanisms.
+
+  [..] The Flash memory interface accelerates code execution with a system of instruction
+      prefetch. 
+
+  [..] The FLASH main features are:
+      (+) Flash memory read operations
+      (+) Flash memory program/erase operations
+      (+) Read / write protections
+      (+) Prefetch on I-Code
+      (+) Option Bytes programming
+
+
+                     ##### How to use this driver #####
+  ==============================================================================
+  [..]                             
+      This driver provides functions and macros to configure and program the FLASH 
+      memory of all STM32L1xx devices.
+    
+      (#) FLASH Memory I/O Programming functions: this group includes all needed
+          functions to erase and program the main memory:

+          
+                 ##### Programming operation functions #####
+  ===============================================================================  
+     [..]
+     This subsection provides a set of functions allowing to manage the FLASH 
+     program operations.
+  
+    [..] The FLASH Memory Programming functions, includes the following functions:
+     (+) HAL_FLASH_Unlock(void);
+     (+) HAL_FLASH_Lock(void);
+     (+) HAL_FLASH_Program(uint32_t TypeProgram, uint32_t Address, uint32_t Data)
+     (+) HAL_FLASH_Program_IT(uint32_t TypeProgram, uint32_t Address, uint32_t Data)
+    
+     [..] Any operation of erase or program should follow these steps:
+     (#) Call the HAL_FLASH_Unlock() function to enable the flash control register and 
+         program memory access.
+     (#) Call the desired function to erase page or program data.
+     (#) Call the HAL_FLASH_Lock() to disable the flash program memory access 
+        (recommended to protect the FLASH memory against possible unwanted operation).
+  
+               ##### Option Bytes Programming functions ##### 
+   ==============================================================================  
+  
+     [..] The FLASH_Option Bytes Programming_functions, includes the following functions:
+     (+) HAL_FLASH_OB_Unlock(void);
+     (+) HAL_FLASH_OB_Lock(void);
+     (+) HAL_FLASH_OB_Launch(void);

+     (+) HAL_FLASHEx_OBGetConfig(FLASH_OBProgramInitTypeDef *pOBInit);
+    
+     [..] Any operation of erase or program should follow these steps:
+     (#) Call the HAL_FLASH_OB_Unlock() function to enable the Flash option control 
+         register access.
+     (#) Call the following functions to program the desired option bytes.
+         (++) HAL_FLASHEx_OBProgram(FLASH_OBProgramInitTypeDef *pOBInit);      
+     (#) Once all needed option bytes to be programmed are correctly written, call the
+         HAL_FLASH_OB_Launch(void) function to launch the Option Bytes programming process.
+     (#) Call the HAL_FLASH_OB_Lock() to disable the Flash option control register access (recommended
+         to protect the option Bytes against possible unwanted operations).
+  
+    [..] Proprietary code Read Out Protection (PcROP):    
+    (#) The PcROP sector is selected by using the same option bytes as the Write
+        protection. As a result, these 2 options are exclusive each other.
+    (#) To activate PCROP mode for Flash sectors(s), you need to follow the sequence below:
+        (++) Use this function HAL_FLASHEx_AdvOBProgram with PCROPState = OB_PCROP_STATE_ENABLE.

+    [..] Any operation of erase or program should follow these steps:
+    (#) Call the @ref HAL_FLASH_OB_Unlock() function to enable the Flash option control 
+        register access.
+    (#) Call following function to program the desired option bytes.
+        (++) @ref HAL_FLASHEx_OBProgram:
+         - To Enable/Disable the desired sector write protection.
+         - To set the desired read Protection Level.
+         - To configure the user option Bytes: IWDG, STOP and the Standby.
+         - To Set the BOR level.
+    (#) Once all needed option bytes to be programmed are correctly written, call the
+        @ref HAL_FLASH_OB_Launch(void) function to launch the Option Bytes programming process.
+    (#) Call the @ref HAL_FLASH_OB_Lock() to disable the Flash option control register access (recommended
+        to protect the option Bytes against possible unwanted operations).
+
+    [..] Proprietary code Read Out Protection (PcROP):
+    (#) The PcROP sector is selected by using the same option bytes as the Write
+        protection (nWRPi bits). As a result, these 2 options are exclusive each other.
+    (#) In order to activate the PcROP (change the function of the nWRPi option bits), 
+        the SPRMOD option bit must be activated.
+    (#) The active value of nWRPi bits is inverted when PCROP mode is active, this
+        means: if SPRMOD = 1 and nWRPi = 1 (default value), then the user sector "i"
+        is read/write protected.
+    (#) To activate PCROP mode for Flash sector(s), you need to call the following function:
+        (++) @ref HAL_FLASHEx_AdvOBProgram in selecting sectors to be read/write protected
+        (++) @ref HAL_FLASHEx_OB_SelectPCROP to enable the read/write protection
+    (#) PcROP is available only in STM32L151xBA, STM32L152xBA, STM32L151xC, STM32L152xC & STM32L162xC devices.

+  * @brief   GPIO HAL module driver.
+  *          This file provides firmware functions to manage the following 
+  *          functionalities of the General Purpose Input/Output (GPIO) peripheral:
+  *           + Initialization and de-initialization functions
+  *           + IO operation functions
+  *         
+  @verbatim
+  ==============================================================================
+                    ##### GPIO Peripheral features #####
+  ==============================================================================         
+  [..] 
+  Each port bit of the general-purpose I/O (GPIO) ports can be individually 
+  configured by software in several modes:
+  (+) Input mode 
+  (+) Analog mode
+  (+) Output mode
+  (+) Alternate function mode
+  (+) External interrupt/event lines
+ 
+  [..]  
+  During and just after reset, the alternate functions and external interrupt  
+  lines are not active and the I/O ports are configured in input floating mode.
+  
+  [..]   
+  All GPIO pins have weak internal pull-up and pull-down resistors, which can be 
+  activated or not.
+
+  [..]
+  In Output or Alternate mode, each IO can be configured on open-drain or push-pull
+  type and the IO speed can be selected depending on the VDD value.
+  
+  [..]
+  The microcontroller IO pins are connected to onboard peripherals/modules through a 
+  multiplexer that allows only one peripheral s alternate function (AF) connected 
+  to an IO pin at a time. In this way, there can be no conflict between peripherals 
+  sharing the same IO pin. 
+  
+  [..]  
+  All ports have external interrupt/event capability. To use external interrupt 
+  lines, the port must be configured in input mode. All available GPIO pins are 
+  connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
+  
+  [..]  
+  The external interrupt/event controller consists of up to 28 edge detectors 
+  (depending on products 16 lines are connected to GPIO) for generating event/interrupt
+  requests (each input line can be independently configured to select the type 
+  (interrupt or event) and the corresponding trigger event (rising or falling or both). 
+  Each line can also be masked independently. 
+   
+            ##### How to use this driver #####
+  ==============================================================================

+   (#) Enable the GPIO AHB clock using the following function : __GPIOx_CLK_ENABLE(). 
+                                    
+   (#) Configure the GPIO pin(s) using HAL_GPIO_Init().
+       (++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure
+       (++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef 
+            structure.
+       (++) In case of Output or alternate function mode selection: the speed is 
+            configured through "Speed" member from GPIO_InitTypeDef structure, 
+            the speed is configurable: Low, Medium and High.
+       (++) If alternate mode is selected, the alternate function connected to the IO
+            is configured through "Alternate" member from GPIO_InitTypeDef structure
+       (++) Analog mode is required when a pin is to be used as ADC channel 
+            or DAC output.
+       (++) In case of external interrupt/event selection the "Mode" member from 
+            GPIO_InitTypeDef structure select the type (interrupt or event) and 
+            the corresponding trigger event (rising or falling or both).
+  
+   (#) In case of external interrupt/event mode selection, configure NVIC IRQ priority 
+       mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
+       HAL_NVIC_EnableIRQ().
+  
+   (#) HAL_GPIO_DeInit allows to set register values to their reset value. It's also 
+       recommended to use it to unconfigure pin which was used as an external interrupt 
+       or in event mode. That's the only way to reset corresponding bit in EXTI & SYSCFG 
+       registers.
+  
+   (#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
+  
+   (#) To set/reset the level of a pin configured in output mode use 
+       HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
+  
+   (#) To lock pin configuration until next reset use HAL_GPIO_LockPin().
+  
+   (#) During and just after reset, the alternate functions are not 
+       active and the GPIO pins are configured in input floating mode (except JTAG
+       pins).
+  
+   (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose 
+       (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has 
+       priority over the GPIO function.
+  
+   (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as 
+       general purpose PH0 and PH1, respectively, when the HSE oscillator is off. 
+       The HSE has priority over the GPIO function.

+     [..]
+       Below the list of most used macros in I2C HAL driver.
+
+      (+) @ref __HAL_I2C_ENABLE:     Enable the I2C peripheral
+      (+) @ref __HAL_I2C_DISABLE:    Disable the I2C peripheral

+     =============================================
+
+     The compilation flag USE_HAL_I2C_REGISTER_CALLBACKS when set to 1
+     allows the user to configure dynamically the driver callbacks.
+     Use Functions @ref HAL_I2C_RegisterCallback() or @ref HAL_I2C_RegisterAddrCallback()
+     to register an interrupt callback.
+
+     Function @ref HAL_I2C_RegisterCallback() allows to register following callbacks:
+       (+) MasterTxCpltCallback : callback for Master transmission end of transfer.
+       (+) MasterRxCpltCallback : callback for Master reception end of transfer.
+       (+) SlaveTxCpltCallback  : callback for Slave transmission end of transfer.
+       (+) SlaveRxCpltCallback  : callback for Slave reception end of transfer.

+       (+) ErrorCallback        : callback for error detection.
+       (+) AbortCpltCallback    : callback for abort completion process.
+       (+) MspInitCallback      : callback for Msp Init.
+       (+) MspDeInitCallback    : callback for Msp DeInit.
+     This function takes as parameters the HAL peripheral handle, the Callback ID
+     and a pointer to the user callback function.
+
+     For specific callback AddrCallback use dedicated register callbacks : @ref HAL_I2C_RegisterAddrCallback().
+
+     Use function @ref HAL_I2C_UnRegisterCallback to reset a callback to the default
+     weak function.
+     @ref HAL_I2C_UnRegisterCallback takes as parameters the HAL peripheral handle,
+     and the Callback ID.
+     This function allows to reset following callbacks:
+       (+) MasterTxCpltCallback : callback for Master transmission end of transfer.
+       (+) MasterRxCpltCallback : callback for Master reception end of transfer.
+       (+) SlaveTxCpltCallback  : callback for Slave transmission end of transfer.
+       (+) SlaveRxCpltCallback  : callback for Slave reception end of transfer.
+       (+) ListenCpltCallback   : callback for end of listen mode.
+       (+) MemTxCpltCallback    : callback for Memory transmission end of transfer.
+       (+) MemRxCpltCallback    : callback for Memory reception end of transfer.
+       (+) ErrorCallback        : callback for error detection.
+       (+) AbortCpltCallback    : callback for abort completion process.
+       (+) MspInitCallback      : callback for Msp Init.
+       (+) MspDeInitCallback    : callback for Msp DeInit.
+
+     For callback AddrCallback use dedicated register callbacks : @ref HAL_I2C_UnRegisterAddrCallback().
+
+     By default, after the @ref HAL_I2C_Init() and when the state is @ref HAL_I2C_STATE_RESET
+     all callbacks are set to the corresponding weak functions:
+     examples @ref HAL_I2C_MasterTxCpltCallback(), @ref HAL_I2C_MasterRxCpltCallback().
+     Exception done for MspInit and MspDeInit functions that are
+     reset to the legacy weak functions in the @ref HAL_I2C_Init()/ @ref HAL_I2C_DeInit() only when
+     these callbacks are null (not registered beforehand).
+     If MspInit or MspDeInit are not null, the @ref HAL_I2C_Init()/ @ref HAL_I2C_DeInit()
+     keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
+
+     Callbacks can be registered/unregistered in @ref HAL_I2C_STATE_READY state only.
+     Exception done MspInit/MspDeInit functions that can be registered/unregistered
+     in @ref HAL_I2C_STATE_READY or @ref HAL_I2C_STATE_RESET state,
+     thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
+     Then, the user first registers the MspInit/MspDeInit user callbacks
+     using @ref HAL_I2C_RegisterCallback() before calling @ref HAL_I2C_DeInit()
+     or @ref HAL_I2C_Init() function.
+
+     When the compilation flag USE_HAL_I2C_REGISTER_CALLBACKS is set to 0 or
+     not defined, the callback registration feature is not available and all callbacks
+     are set to the corresponding weak functions.

+
+   *** I2S HAL driver macros list ***
+   ===================================
+   [..]
+       Callback registration:
+
+      (#) The compilation flag USE_HAL_I2S_REGISTER_CALLBACKS when set to 1U
+          allows the user to configure dynamically the driver callbacks.
+          Use Functions HAL_I2S_RegisterCallback() to register an interrupt callback.
+
+          Function HAL_I2S_RegisterCallback() allows to register following callbacks:
+            (+) TxCpltCallback        : I2S Tx Completed callback
+            (+) RxCpltCallback        : I2S Rx Completed callback
+            (+) TxHalfCpltCallback    : I2S Tx Half Completed callback
+            (+) RxHalfCpltCallback    : I2S Rx Half Completed callback
+            (+) ErrorCallback         : I2S Error callback
+            (+) MspInitCallback       : I2S Msp Init callback
+            (+) MspDeInitCallback     : I2S Msp DeInit callback
+          This function takes as parameters the HAL peripheral handle, the Callback ID
+          and a pointer to the user callback function.
+
+
+      (#) Use function HAL_I2S_UnRegisterCallback to reset a callback to the default
+          weak function.
+          HAL_I2S_UnRegisterCallback takes as parameters the HAL peripheral handle,
+          and the Callback ID.
+          This function allows to reset following callbacks:
+            (+) TxCpltCallback        : I2S Tx Completed callback
+            (+) RxCpltCallback        : I2S Rx Completed callback
+            (+) TxHalfCpltCallback    : I2S Tx Half Completed callback
+            (+) RxHalfCpltCallback    : I2S Rx Half Completed callback
+            (+) ErrorCallback         : I2S Error callback
+            (+) MspInitCallback       : I2S Msp Init callback
+            (+) MspDeInitCallback     : I2S Msp DeInit callback
+
+       By default, after the HAL_I2S_Init() and when the state is HAL_I2S_STATE_RESET
+       all callbacks are set to the corresponding weak functions:
+       examples HAL_I2S_MasterTxCpltCallback(), HAL_I2S_MasterRxCpltCallback().
+       Exception done for MspInit and MspDeInit functions that are
+       reset to the legacy weak functions in the HAL_I2S_Init()/ HAL_I2S_DeInit() only when
+       these callbacks are null (not registered beforehand).
+       If MspInit or MspDeInit are not null, the HAL_I2S_Init()/ HAL_I2S_DeInit()
+       keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
+
+       Callbacks can be registered/unregistered in HAL_I2S_STATE_READY state only.
+       Exception done MspInit/MspDeInit functions that can be registered/unregistered
+       in HAL_I2S_STATE_READY or HAL_I2S_STATE_RESET state,
+       thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
+       Then, the user first registers the MspInit/MspDeInit user callbacks
+       using HAL_I2S_RegisterCallback() before calling HAL_I2S_DeInit()
+       or HAL_I2S_Init() function.
+
+       When The compilation define USE_HAL_I2S_REGISTER_CALLBACKS is set to 0 or
+       not defined, the callback registering feature is not available
+       and weak (surcharged) callbacks are used.

+       (++) No-Blocking mode : The communication is performed using Interrupts
+            or DMA. These functions return the status of the transfer startup.
+            The end of the data processing will be indicated through the
+            dedicated I2S IRQ when using Interrupt mode or the DMA IRQ when
+            using DMA mode.

+  ==============================================================================
+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    The IRDA HAL driver can be used as follows:
+
+    (#) Declare a IRDA_HandleTypeDef handle structure (eg. IRDA_HandleTypeDef hirda).
+    (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API:
+        (##) Enable the USARTx interface clock.
+        (##) IRDA pins configuration:
+            (+++) Enable the clock for the IRDA GPIOs.
+            (+++) Configure IRDA pins as alternate function pull-up.
+        (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
+             and HAL_IRDA_Receive_IT() APIs):
+            (+++) Configure the USARTx interrupt priority.
+            (+++) Enable the NVIC USART IRQ handle.
+        (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
+             and HAL_IRDA_Receive_DMA() APIs):
+            (+++) Declare a DMA handle structure for the Tx/Rx channel.
+            (+++) Enable the DMAx interface clock.
+            (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
+            (+++) Configure the DMA Tx/Rx channel.
+            (+++) Associate the initialized DMA handle to the IRDA DMA Tx/Rx handle.
+            (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
+            (+++) Configure the IRDAx interrupt priority and enable the NVIC USART IRQ handle
+                  (used for last byte sending completion detection in DMA non circular mode)
+
+    (#) Program the Baud Rate, Word Length, Parity, IrDA Mode, Prescaler
+        and Mode(Receiver/Transmitter) in the hirda Init structure.
+
+    (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
+        (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+             by calling the customized HAL_IRDA_MspInit() API.
+
+         -@@- The specific IRDA interrupts (Transmission complete interrupt,
+             RXNE interrupt and Error Interrupts) will be managed using the macros
+             __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
+
+    (#) Three operation modes are available within this driver :
+
+    *** Polling mode IO operation ***
+    =================================
+    [..]
+      (+) Send an amount of data in blocking mode using HAL_IRDA_Transmit()
+      (+) Receive an amount of data in blocking mode using HAL_IRDA_Receive()
+
+    *** Interrupt mode IO operation ***
+    ===================================
+    [..]
+      (+) Send an amount of data in non blocking mode using HAL_IRDA_Transmit_IT()
+      (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can
+           add his own code by customization of function pointer HAL_IRDA_TxCpltCallback
+      (+) Receive an amount of data in non blocking mode using HAL_IRDA_Receive_IT()
+      (+) At reception end of transfer HAL_IRDA_RxCpltCallback is executed and user can
+           add his own code by customization of function pointer HAL_IRDA_RxCpltCallback
+      (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can
+           add his own code by customization of function pointer HAL_IRDA_ErrorCallback
+
+    *** DMA mode IO operation ***
+    =============================
+    [..]
+      (+) Send an amount of data in non blocking mode (DMA) using HAL_IRDA_Transmit_DMA()
+      (+) At transmission end of half transfer HAL_IRDA_TxHalfCpltCallback is executed and user can
+            add his own code by customization of function pointer HAL_IRDA_TxHalfCpltCallback
+      (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can
+           add his own code by customization of function pointer HAL_IRDA_TxCpltCallback
+      (+) Receive an amount of data in non blocking mode (DMA) using HAL_IRDA_Receive_DMA()

+      (+) Resume the DMA Transfer using HAL_IRDA_DMAResume()
+      (+) Stop the DMA Transfer using HAL_IRDA_DMAStop()
+
+    *** IRDA HAL driver macros list ***
+    ===================================
+    [..]
+      Below the list of most used macros in IRDA HAL driver.
+
+       (+) __HAL_IRDA_ENABLE: Enable the IRDA peripheral
+       (+) __HAL_IRDA_DISABLE: Disable the IRDA peripheral
+       (+) __HAL_IRDA_GET_FLAG : Check whether the specified IRDA flag is set or not
+       (+) __HAL_IRDA_CLEAR_FLAG : Clear the specified IRDA pending flag
+       (+) __HAL_IRDA_ENABLE_IT: Enable the specified IRDA interrupt
+       (+) __HAL_IRDA_DISABLE_IT: Disable the specified IRDA interrupt
+       (+) __HAL_IRDA_GET_IT_SOURCE: Check whether the specified IRDA interrupt has occurred or not
+
+    [..]
+     (@) You can refer to the IRDA HAL driver header file for more useful macros
+
+    ##### Callback registration #####
+    ==================================
+
+    [..]
+      The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS when set to 1
+      allows the user to configure dynamically the driver callbacks.
+
+    [..]
+      Use Function @ref HAL_IRDA_RegisterCallback() to register a user callback.
+      Function @ref HAL_IRDA_RegisterCallback() allows to register following callbacks:
+       (+) TxHalfCpltCallback        : Tx Half Complete Callback.
+       (+) TxCpltCallback            : Tx Complete Callback.
+       (+) RxHalfCpltCallback        : Rx Half Complete Callback.
+       (+) RxCpltCallback            : Rx Complete Callback.
+       (+) ErrorCallback             : Error Callback.
+       (+) AbortCpltCallback         : Abort Complete Callback.
+       (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
+       (+) AbortReceiveCpltCallback  : Abort Receive Complete Callback.
+       (+) MspInitCallback           : IRDA MspInit.
+       (+) MspDeInitCallback         : IRDA MspDeInit.
+      This function takes as parameters the HAL peripheral handle, the Callback ID
+      and a pointer to the user callback function.
+
+    [..]
+      Use function @ref HAL_IRDA_UnRegisterCallback() to reset a callback to the default
+      weak (surcharged) function.
+      @ref HAL_IRDA_UnRegisterCallback() takes as parameters the HAL peripheral handle,
+      and the Callback ID.
+      This function allows to reset following callbacks:
+       (+) TxHalfCpltCallback        : Tx Half Complete Callback.
+       (+) TxCpltCallback            : Tx Complete Callback.
+       (+) RxHalfCpltCallback        : Rx Half Complete Callback.
+       (+) RxCpltCallback            : Rx Complete Callback.
+       (+) ErrorCallback             : Error Callback.
+       (+) AbortCpltCallback         : Abort Complete Callback.
+       (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
+       (+) AbortReceiveCpltCallback  : Abort Receive Complete Callback.
+       (+) MspInitCallback           : IRDA MspInit.
+       (+) MspDeInitCallback         : IRDA MspDeInit.
+
+    [..]
+      By default, after the @ref HAL_IRDA_Init() and when the state is HAL_IRDA_STATE_RESET
+      all callbacks are set to the corresponding weak (surcharged) functions:
+      examples @ref HAL_IRDA_TxCpltCallback(), @ref HAL_IRDA_RxHalfCpltCallback().
+      Exception done for MspInit and MspDeInit functions that are respectively
+      reset to the legacy weak (surcharged) functions in the @ref HAL_IRDA_Init()
+      and @ref HAL_IRDA_DeInit() only when these callbacks are null (not registered beforehand).
+      If not, MspInit or MspDeInit are not null, the @ref HAL_IRDA_Init() and @ref HAL_IRDA_DeInit()
+      keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
+
+    [..]
+      Callbacks can be registered/unregistered in HAL_IRDA_STATE_READY state only.
+      Exception done MspInit/MspDeInit that can be registered/unregistered
+      in HAL_IRDA_STATE_READY or HAL_IRDA_STATE_RESET state, thus registered (user)
+      MspInit/DeInit callbacks can be used during the Init/DeInit.
+      In that case first register the MspInit/MspDeInit user callbacks
+      using @ref HAL_IRDA_RegisterCallback() before calling @ref HAL_IRDA_DeInit()
+      or @ref HAL_IRDA_Init() function.
+
+    [..]
+      When The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS is set to 0 or
+      not defined, the callback registration feature is not available
+      and weak (surcharged) callbacks are used.
+
+  @endverbatim
+     [..]
+       (@) Additionnal remark: If the parity is enabled, then the MSB bit of the data written
+           in the data register is transmitted but is changed by the parity bit.
+           Depending on the frame length defined by the M bit (8-bits or 9-bits),
+           the possible IRDA frame formats are as listed in the following table:
+    +-------------------------------------------------------------+
+    |   M bit |  PCE bit  |            IRDA frame                 |
+    |---------------------|---------------------------------------|
+    |    0    |    0      |    | SB | 8 bit data | 1 STB |        |
+    |---------|-----------|---------------------------------------|
+    |    0    |    1      |    | SB | 7 bit data | PB | 1 STB |   |
+    |---------|-----------|---------------------------------------|
+    |    1    |    0      |    | SB | 9 bit data | 1 STB |        |
+    |---------|-----------|---------------------------------------|
+    |    1    |    1      |    | SB | 8 bit data | PB | 1 STB |   |

+    [..]
+    This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
+    in asynchronous IrDA mode.
+      (+) For the asynchronous mode only these parameters can be configured:
+        (++) BaudRate
+        (++) WordLength
+        (++) Parity: If the parity is enabled, then the MSB bit of the data written
+             in the data register is transmitted but is changed by the parity bit.
+             Depending on the frame length defined by the M bit (8-bits or 9-bits),
+             please refer to Reference manual for possible IRDA frame formats.
+        (++) Prescaler: A pulse of width less than two and greater than one PSC period(s) may or may

+  ==============================================================================
+    [..]
+    This subsection provides a set of functions allowing to manage the IRDA data transfers.
+    IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
+    on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
+    is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
+    While receiving data, transmission should be avoided as the data to be transmitted
+    could be corrupted.
+
+    (#) There are two modes of transfer:
+       (++) Blocking mode: The communication is performed in polling mode.
+            The HAL status of all data processing is returned by the same function
+            after finishing transfer.
+       (++) Non-Blocking mode: The communication is performed using Interrupts
+           or DMA, these API's return the HAL status.
+           The end of the data processing will be indicated through the
+           dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
+           using DMA mode.
+           The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
+           will be executed respectively at the end of the Transmit or Receive process
+           The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected
+
+    (#) Blocking mode APIs are :
+        (++) HAL_IRDA_Transmit()
+        (++) HAL_IRDA_Receive()
+
+    (#) Non Blocking mode APIs with Interrupt are :
+        (++) HAL_IRDA_Transmit_IT()
+        (++) HAL_IRDA_Receive_IT()
+        (++) HAL_IRDA_IRQHandler()
+
+    (#) Non Blocking mode functions with DMA are :
+        (++) HAL_IRDA_Transmit_DMA()
+        (++) HAL_IRDA_Receive_DMA()
+        (++) HAL_IRDA_DMAPause()
+        (++) HAL_IRDA_DMAResume()
+        (++) HAL_IRDA_DMAStop()
+
+    (#) A set of Transfer Complete Callbacks are provided in Non Blocking mode:
+        (++) HAL_IRDA_TxHalfCpltCallback()
+        (++) HAL_IRDA_TxCpltCallback()
+        (++) HAL_IRDA_RxHalfCpltCallback()
+        (++) HAL_IRDA_RxCpltCallback()
+        (++) HAL_IRDA_ErrorCallback()
+
+    (#) Non-Blocking mode transfers could be aborted using Abort API's :
+        (+) HAL_IRDA_Abort()
+        (+) HAL_IRDA_AbortTransmit()
+        (+) HAL_IRDA_AbortReceive()
+        (+) HAL_IRDA_Abort_IT()
+        (+) HAL_IRDA_AbortTransmit_IT()
+        (+) HAL_IRDA_AbortReceive_IT()
+
+    (#) For Abort services based on interrupts (HAL_IRDA_Abortxxx_IT), a set of Abort Complete Callbacks are provided:
+        (+) HAL_IRDA_AbortCpltCallback()
+        (+) HAL_IRDA_AbortTransmitCpltCallback()
+        (+) HAL_IRDA_AbortReceiveCpltCallback()
+
+    (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
+        Errors are handled as follows :
+        (+) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
+            to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
+            Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
+            and HAL_IRDA_ErrorCallback() user callback is executed. Transfer is kept ongoing on IRDA side.
+            If user wants to abort it, Abort services should be called by user.
+        (+) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
+            This concerns Overrun Error In Interrupt mode reception and all errors in DMA mode.
+            Error code is set to allow user to identify error type, and HAL_IRDA_ErrorCallback() user callback is executed.

+  *          This file provides firmware functions to manage the following 
+  *          functionalities of the Independent Watchdog (IWDG) peripheral:
+  *           + Initialization and Start functions
+  *           + IO operation functions
+  *
+  @verbatim
+  ==============================================================================
+                    ##### IWDG Generic features #####
+  ==============================================================================
+  [..]
+    (+) The IWDG can be started by either software or hardware (configurable
+        through option byte).
+
+    (+) The IWDG is clocked by Low-Speed clock (LSI) and thus stays active even
+        if the main clock fails.
+
+    (+) Once the IWDG is started, the LSI is forced ON and both can not be 
+        disabled. The counter starts counting down from the reset value (0xFFF).
+        When it reaches the end of count value (0x000) a reset signal is 
+        generated (IWDG reset).
+
+    (+) Whenever the key value 0x0000 AAAA is written in the IWDG_KR register, 
+        the IWDG_RLR value is reloaded in the counter and the watchdog reset is
+        prevented.
+
+    (+) The IWDG is implemented in the VDD voltage domain that is still functional
+        in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).
+        IWDGRST flag in RCC_CSR register can be used to inform when an IWDG
+        reset occurs.
+
+    (+) Debug mode : When the microcontroller enters debug mode (core halted),
+        the IWDG counter either continues to work normally or stops, depending 
+        on DBG_IWDG_STOP configuration bit in DBG module, accessible through
+        __HAL_DBGMCU_FREEZE_IWDG() and __HAL_DBGMCU_UNFREEZE_IWDG() macros
+
+    (+) Min-max timeout value @37KHz (LSI): ~108us / ~28.3s
+         The IWDG timeout may vary due to LSI frequency dispersion. STM32L1xx
+         devices provide the capability to measure the LSI frequency (LSI clock
+         connected internally to TIM10 CH1 input capture). The measured value
+         can be used to have an IWDG timeout with an acceptable accuracy. 
+         For more information, please refer to the STM32L1xx Reference manual.
+
+                     ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    (#) Use IWDG using HAL_IWDG_Init() function to :
+      (++) Enable instance by writing Start keyword in IWDG_KEY register. LSI 
+           clock is forced ON and IWDG counter starts downcounting.
+      (++) Enable write access to configuration register: IWDG_PR, IWDG_RLR.
+      (++) Configure the IWDG prescaler and counter reload value. This reload 
+           value will be loaded in the IWDG counter each time the watchdog is 
+           reloaded, then the IWDG will start counting down from this value.
+      (++) wait for status flags to be reset"
+
+    (#) Then the application program must refresh the IWDG counter at regular
+        intervals during normal operation to prevent an MCU reset, using
+        HAL_IWDG_Refresh() function.
+
+     *** IWDG HAL driver macros list ***
+     ====================================
+     [..]
+       Below the list of most used macros in IWDG HAL driver:
+      (+) __HAL_IWDG_START: Enable the IWDG peripheral
+      (+) __HAL_IWDG_RELOAD_COUNTER: Reloads IWDG counter with value defined in
+          the reload register

+                        ##### How to use this driver #####
+  ==============================================================================   
+      [..] The LCD HAL driver can be used as follows:
+    
+      (#) Declare a LCD_HandleTypeDef handle structure.
+
+      (#) Initialize the LCD low level resources by implement the HAL_LCD_MspInit() API:
+          (##) Enable the LCDCLK (same as RTCCLK): to configure the RTCCLK/LCDCLK, proceed as follows:
+               (+++) Use RCC function HAL_RCCEx_PeriphCLKConfig in indicating RCC_PERIPHCLK_LCD and 
+                     selected clock source (HSE, LSI or LSE)
+               (+++) The frequency generator allows you to achieve various LCD frame rates 
+                     starting from an LCD input clock frequency (LCDCLK) which can vary 
+                     from 32 kHz up to 1 MHz.
+          (##) LCD pins configuration:
+               (+++) Enable the clock for the LCD GPIOs.
+               (+++) Configure these LCD pins as alternate function no-pull.
+          (##) Enable the LCD interface clock.
+
+      (#) Program the Prescaler, Divider, Blink mode, Blink Frequency Duty, Bias,
+           Voltage Source, Dead Time, Pulse On Duration and Contrast in the hlcd Init structure.
+
+      (#) Initialize the LCD registers by calling the HAL_LCD_Init() API.
+
+      -@- The HAL_LCD_Init() API configures also the low level Hardware GPIO, CLOCK, ...etc)
+          by calling the custumed HAL_LCD_MspInit() API.
+      -@- After calling the HAL_LCD_Init() the LCD RAM memory is cleared
+
+      (#) Optionally you can update the LCD configuration using these macros:
+          (++) LCD High Drive using the __HAL_LCD_HIGHDRIVER_ENABLE() and __HAL_LCD_HIGHDRIVER_DISABLE() macros
+          (++) LCD Pulse ON Duration using the __HAL_LCD_PULSEONDURATION_CONFIG() macro
+          (++) LCD Dead Time using the __HAL_LCD_DEADTIME_CONFIG() macro  
+          (++) The LCD Blink mode and frequency using the __HAL_LCD_BLINK_CONFIG() macro
+          (++) The LCD Contrast using the __HAL_LCD_CONTRAST_CONFIG() macro  
+
+      (#) Write to the LCD RAM memory using the HAL_LCD_Write() API, this API can be called
+          more time to update the different LCD RAM registers before calling 
+          HAL_LCD_UpdateDisplayRequest() API.
+
+      (#) The HAL_LCD_Clear() API can be used to clear the LCD RAM memory.
+
+      (#) When LCD RAM memory is updated enable the update display request using
+          the HAL_LCD_UpdateDisplayRequest() API.
+
+      [..] LCD and low power modes:
+           (#) The LCD remain active during STOP mode.

+ [..] Using its double buffer memory the LCD controller ensures the coherency of the 
+ displayed information without having to use interrupts to control LCD_RAM 
+ modification.
+ (+)The application software can access the first buffer level (LCD_RAM) through 
+ the APB interface. Once it has modified the LCD_RAM using the HAL_LCD_Write() API,
+ it sets the UDR flag in the LCD_SR register using the HAL_LCD_UpdateDisplayRequest() API.
+ This UDR flag (update display request) requests the updated information to be 
+ moved into the second buffer level (LCD_DISPLAY).
+ (+)This operation is done synchronously with the frame (at the beginning of the 
+ next frame), until the update is completed, the LCD_RAM is write protected and 
+ the UDR flag stays high.
+ (+)Once the update is completed another flag (UDD - Update Display Done) is set and
+ generates an interrupt if the UDDIE bit in the LCD_FCR register is set.
+ The time it takes to update LCD_DISPLAY is, in the worst case, one odd and one 
+ even frame.
+ (+)The update will not occur (UDR = 1 and UDD = 0) until the display is 
+ enabled (LCDEN = 1).

+  * @brief   NOR HAL module driver.
+  *          This file provides a generic firmware to drive NOR memories mounted 
+  *          as external device.
+  *         
+  @verbatim
+  ==============================================================================
+                     ##### How to use this driver #####
+  ==============================================================================       
+    [..]
+      This driver is a generic layered driver which contains a set of APIs used to 
+      control NOR flash memories. It uses the FSMC layer functions to interface 
+      with NOR devices. This driver is used as follows:
+    
+      (+) NOR flash memory configuration sequence using the function HAL_NOR_Init() 
+          with control and timing parameters for both normal and extended mode.
+            
+      (+) Read NOR flash memory manufacturer code and device IDs using the function
+          HAL_NOR_Read_ID(). The read information is stored in the NOR_ID_TypeDef 
+          structure declared by the function caller. 
+        
+      (+) Access NOR flash memory by read/write data unit operations using the functions
+          HAL_NOR_Read(), HAL_NOR_Program().
+        
+      (+) Perform NOR flash erase block/chip operations using the functions 
+          HAL_NOR_Erase_Block() and HAL_NOR_Erase_Chip().
+        
+      (+) Read the NOR flash CFI (common flash interface) IDs using the function
+          HAL_NOR_Read_CFI(). The read information is stored in the NOR_CFI_TypeDef
+          structure declared by the function caller.
+        
+      (+) You can also control the NOR device by calling the control APIs HAL_NOR_WriteOperation_Enable()/
+          HAL_NOR_WriteOperation_Disable() to respectively enable/disable the NOR write operation  
+       
+      (+) You can monitor the NOR device HAL state by calling the function
+          HAL_NOR_GetState() 
+    [..]
+     (@) This driver is a set of generic APIs which handle standard NOR flash operations.
+         If a NOR flash device contains different operations and/or implementations, 
+         it should be implemented separately.
+
+     *** NOR HAL driver macros list ***
+     ============================================= 
+     [..]
+       Below the list of most used macros in NOR HAL driver.
+       
+      (+) NOR_WRITE : NOR memory write data to specified address

+================================================================================
+          ##### OPAMP Peripheral Features #####
+================================================================================
+  [..] The device integrates up to 3 operational amplifiers OPAMP1, OPAMP2,
+       OPAMP3 (OPAMP3 availability depends on device category)
+       
+       (#) The OPAMP(s) provide(s) several exclusive running modes.
+       (++) Standalone mode
+       (++) Follower mode
+
+       (#) All OPAMP (same for all OPAMPs) can operate in
+       (++) Either Low range (VDDA < 2.4V) power supply
+       (++) Or High range (VDDA > 2.4V) power supply
+
+       (#) Each OPAMP(s) can be configured in normal and low power mode.
+
+       (#) The OPAMP(s) provide(s) calibration capabilities.  
+       (++) Calibration aims at correcting some offset for running mode.
+       (++) The OPAMP uses either factory calibration settings OR user defined 
+           calibration (trimming) settings (i.e. trimming mode).
+       (++) The user defined settings can be figured out using self calibration 
+           handled by HAL_OPAMP_SelfCalibrate, HAL_OPAMPEx_SelfCalibrateAll
+       (++) HAL_OPAMP_SelfCalibrate:
+       (+++) Runs automatically the calibration in 2 steps: for transistors 
+            differential pair high (PMOS) or low (NMOS)
+       (+++) Enables the user trimming mode
+       (+++) Updates the init structure with trimming values with fresh calibration 
+            results.
+            The user may store the calibration results for larger 
+            (ex monitoring the trimming as a function of temperature 
+            for instance)
+       (+++) For devices having several OPAMPs, HAL_OPAMPEx_SelfCalibrateAll
+            runs calibration of all OPAMPs in parallel to save search time.
+            
+       (#) Running mode: Standalone mode 
+       (++) Gain is set externally (gain depends on external loads).
+       (++) Follower mode also possible externally by connecting the inverting input to
+           the output.
+       
+       (#) Running mode: Follower mode
+       (++) No Inverting Input is connected.
+       (++) The OPAMP(s) output(s) are internally connected to inverting input.
+        
+            ##### How to use this driver #####
+================================================================================
+  [..] 
+
+    *** Power supply range ***
+    ============================================
+    [..] To run in low power mode:
+
+      (#) Configure the OPAMP using HAL_OPAMP_Init() function:
+      (++) Select OPAMP_POWERSUPPLY_LOW (VDDA lower than 2.4V)
+      (++) Otherwise select OPAMP_POWERSUPPLY_HIGH (VDDA higher than 2.4V)
+
+    *** Low / normal power mode ***
+    ============================================
+    [..] To run in low power mode:
+
+      (#) Configure the OPAMP using HAL_OPAMP_Init() function:
+      (++) Select OPAMP_POWERMODE_LOWPOWER
+      (++) Otherwise select OPAMP_POWERMODE_NORMAL
+
+    *** Calibration ***
+    ============================================
+    [..] To run the OPAMP calibration self calibration:
+
+      (#) Start calibration using HAL_OPAMP_SelfCalibrate. 
+           Store the calibration results.
+
+    *** Running mode ***
+    ============================================
+      
+    [..] To use the OPAMP, perform the following steps:
+            
+      (#) Fill in the HAL_OPAMP_MspInit() to
+      (++) Enable the OPAMP Peripheral clock using macro __HAL_RCC_OPAMP_CLK_ENABLE()
+      (++) Configure the OPAMP input AND output in analog mode using
+           HAL_GPIO_Init() to map the OPAMP output to the GPIO pin.
+
+      (#) Registrate Callbacks
+      (++) The compilation define  USE_HAL_OPAMP_REGISTER_CALLBACKS when set to 1
+           allows the user to configure dynamically the driver callbacks.
+
+      (++) Use Functions @ref HAL_OPAMP_RegisterCallback() to register a user callback,
+           it allows to register following callbacks:
+      (+++) MspInitCallback         : OPAMP MspInit.
+      (+++) MspDeInitCallback       : OPAMP MspFeInit.
+           This function takes as parameters the HAL peripheral handle, the Callback ID
+           and a pointer to the user callback function.
+
+      (++) Use function @ref HAL_OPAMP_UnRegisterCallback() to reset a callback to the default
+           weak (surcharged) function. It allows to reset following callbacks:
+      (+++) MspInitCallback         : OPAMP MspInit.
+      (+++) MspDeInitCallback       : OPAMP MspdeInit.
+      (+++) All Callbacks
+  
+      (#) Configure the OPAMP using HAL_OPAMP_Init() function:
+      (++) Select the mode
+      (++) Select the inverting input
+      (++) Select the non-inverting input 
+      (++) Select either factory or user defined trimming mode.
+      (++) If the user-defined trimming mode is enabled, select PMOS & NMOS trimming values
+          (typically values set by HAL_OPAMP_SelfCalibrate function).
+      
+      (#) Enable the OPAMP using HAL_OPAMP_Start() function.
+           
+      (#) Disable the OPAMP using HAL_OPAMP_Stop() function.
+      
+      (#) Lock the OPAMP in running mode using HAL_OPAMP_Lock() function.
+          Caution: On STM32L1, HAL OPAMP lock is software lock only (not 
+          hardware lock as on some other STM32 devices)
+
+      (#) If needed, unlock the OPAMP using HAL_OPAMPEx_Unlock() function.
+
+    *** Running mode: change of configuration while OPAMP ON  ***
+    ============================================
+    [..] To Re-configure OPAMP when OPAMP is ON (change on the fly)
+      (#) If needed, fill in the HAL_OPAMP_MspInit()
+      (++) This is the case for instance if you wish to use new OPAMP I/O
+
+      (#) Configure the OPAMP using HAL_OPAMP_Init() function:
+      (++) As in configure case, select first the parameters you wish to modify.
+      
+      (#) Change from low power mode to normal power mode (& vice versa) requires  
+          first HAL_OPAMP_DeInit() (force OPAMP OFF) and then HAL_OPAMP_Init(). 
+          In other words, of OPAMP is ON, HAL_OPAMP_Init can NOT change power mode
+          alone.

+                    ##### How to use this driver #####
+  ==============================================================================
+    [..]
+      The PCD HAL driver can be used as follows:
+
+     (#) Declare a PCD_HandleTypeDef handle structure, for example:
+         PCD_HandleTypeDef  hpcd;
+
+     (#) Fill parameters of Init structure in HCD handle
+
+     (#) Call HAL_PCD_Init() API to initialize the PCD peripheral (Core, Device core, ...)
+
+     (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
+         (##) Enable the PCD/USB Low Level interface clock using
+              (+++) __HAL_RCC_USB_CLK_ENABLE(); For USB Device only FS peripheral
+
+         (##) Initialize the related GPIO clocks
+         (##) Configure PCD pin-out
+         (##) Configure PCD NVIC interrupt
+
+     (#)Associate the Upper USB device stack to the HAL PCD Driver:
+         (##) hpcd.pData = pdev;
+
+     (#)Enable PCD transmission and reception:
+         (##) HAL_PCD_Start();

+ ===============================================================================
+
+    *** PVD configuration ***
+    =========================
+    [..]
+      (+) The PVD is used to monitor the VDD power supply by comparing it to a
+          threshold selected by the PVD Level (PLS[2:0] bits in the PWR_CR).
+      (+) The PVD can use an external input analog voltage (PVD_IN) which is compared
+      internally to VREFINT. The PVD_IN (PB7) has to be configured in Analog mode
+      when PWR_PVDLevel_7 is selected (PLS[2:0] = 111).
+
+      (+) A PVDO flag is available to indicate if VDD/VDDA is higher or lower
+          than the PVD threshold. This event is internally connected to the EXTI
+          line16 and can generate an interrupt if enabled. This is done through
+          __HAL_PWR_PVD_EXTI_ENABLE_IT() macro.
+      (+) The PVD is stopped in Standby mode.
+
+    *** WakeUp pin configuration ***
+    ================================
+    [..]
+      (+) WakeUp pin is used to wake up the system from Standby mode. This pin is
+          forced in input pull-down configuration and is active on rising edges.
+      (+) There are two or three WakeUp pins:
+          WakeUp Pin 1 on PA.00.
+          WakeUp Pin 2 on PC.13.
+          WakeUp Pin 3 on PE.06. : Only on product with GPIOE available
+
+    [..]
+    *** Main and Backup Regulators configuration ***
+    ================================================
+
+      (+) The main internal regulator can be configured to have a tradeoff between
+          performance and power consumption when the device does not operate at
+          the maximum frequency. This is done through __HAL_PWR_VOLTAGESCALING_CONFIG()
+          macro which configure VOS bit in PWR_CR register:
+        (++) When this bit is set (Regulator voltage output Scale 1 mode selected)
+             the System frequency can go up to 32 MHz.
+        (++) When this bit is reset (Regulator voltage output Scale 2 mode selected)
+             the System frequency can go up to 16 MHz.
+        (++) When this bit is reset (Regulator voltage output Scale 3 mode selected)
+             the System frequency can go up to 4.2 MHz.
+
+        Refer to the datasheets for more details.
+
+    *** Low Power modes configuration ***
+    =====================================
+     [..]
+      The device features 5 low-power modes:
+      (+) Low power run mode: regulator in low power mode, limited clock frequency,
+        limited number of peripherals running.
+      (+) Sleep mode: Cortex-M3 core stopped, peripherals kept running.
+      (+) Low power sleep mode: Cortex-M3 core stopped, limited clock frequency,
+         limited number of peripherals running, regulator in low power mode.
+      (+) Stop mode: All clocks are stopped, regulator running, regulator in low power mode.
+      (+) Standby mode: VCORE domain powered off
+
+   *** Low power run mode ***
+   =========================
+    [..]
+       To further reduce the consumption when the system is in Run mode, the regulator can be
+        configured in low power mode. In this mode, the system frequency should not exceed
+        MSI frequency range1.
+        In Low power run mode, all I/O pins keep the same state as in Run mode.
+
+      (+) Entry:
+        (++) VCORE in range2
+        (++) Decrease the system frequency tonot exceed the frequency of MSI frequency range1.
+        (++) The regulator is forced in low power mode using the HAL_PWREx_EnableLowPowerRunMode()
+             function.
+      (+) Exit:
+        (++) The regulator is forced in Main regulator mode using the HAL_PWREx_DisableLowPowerRunMode()
+              function.
+        (++) Increase the system frequency if needed.
+
+   *** Sleep mode ***
+   ==================
+    [..]
+      (+) Entry:
+          The Sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFx)
+              functions with
+          (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
+          (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
+
+      (+) Exit:
+        (++) Any peripheral interrupt acknowledged by the nested vectored interrupt
+              controller (NVIC) can wake up the device from Sleep mode.
+
+   *** Low power sleep mode ***
+   ============================
+    [..]
+      (+) Entry:
+          The Low power sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFx)
+              functions with
+          (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
+          (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
+       (+) The Flash memory can be switched off by using the control bits (SLEEP_PD in the FLASH_ACR register.
+             This reduces power consumption but increases the wake-up time.
+
+      (+) Exit:
+        (++) If the WFI instruction was used to enter Low power sleep mode, any peripheral interrupt
+              acknowledged by the nested vectored interrupt controller (NVIC) can wake up the device
+              from Low power sleep mode. If the WFE instruction was used to enter Low power sleep mode,
+              the MCU exits Sleep mode as soon as an event occurs.
+
+   *** Stop mode ***
+   =================
+    [..]
+      The Stop mode is based on the Cortex-M3 deepsleep mode combined with peripheral
+      clock gating. The voltage regulator can be configured either in normal or low-power mode.
+      In Stop mode, all clocks in the VCORE domain are stopped, the PLL, the MSI, the HSI and
+      the HSE RC oscillators are disabled. Internal SRAM and register contents are preserved.
+      To get the lowest consumption in Stop mode, the internal Flash memory also enters low
+      power mode. When the Flash memory is in power-down mode, an additional startup delay is
+      incurred when waking up from Stop mode.
+      To minimize the consumption In Stop mode, VREFINT, the BOR, PVD, and temperature
+      sensor can be switched off before entering Stop mode. They can be switched on again by
+      software after exiting Stop mode using the ULP bit in the PWR_CR register.
+      In Stop mode, all I/O pins keep the same state as in Run mode.
+
+      (+) Entry:
+           The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI )
+             function with:
+          (++) Main regulator ON.
+          (++) Low Power regulator ON.
+          (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
+          (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
+      (+) Exit:
+        (++) By issuing an interrupt or a wakeup event, the MSI RC oscillator is selected as system clock.
+
+   *** Standby mode ***
+   ====================
+     [..]
+      The Standby mode allows to achieve the lowest power consumption. It is based on the
+      Cortex-M3 deepsleep mode, with the voltage regulator disabled. The VCORE domain is
+      consequently powered off. The PLL, the MSI, the HSI oscillator and the HSE oscillator are
+      also switched off. SRAM and register contents are lost except for the RTC registers, RTC
+      backup registers and Standby circuitry.
+
+      To minimize the consumption In Standby mode, VREFINT, the BOR, PVD, and temperature
+       sensor can be switched off before entering the Standby mode. They can be switched
+       on again by software after exiting the Standby mode.
+       function.
+
+      (+) Entry:
+        (++) The Standby mode is entered using the HAL_PWR_EnterSTANDBYMode() function.
+      (+) Exit:
+        (++) WKUP pin rising edge, RTC alarm (Alarm A and Alarm B), RTC wakeup,
+             tamper event, time-stamp event, external reset in NRST pin, IWDG reset.
+
+   *** Auto-wakeup (AWU) from low-power mode ***
+   =============================================
+    [..]
+      The MCU can be woken up from low-power mode by an RTC Alarm event, an RTC
+      Wakeup event, a tamper event, a time-stamp event, or a comparator event,
+      without depending on an external interrupt (Auto-wakeup mode).
+
+    (+) RTC auto-wakeup (AWU) from the Stop mode
+        (++) To wake up from the Stop mode with an RTC alarm event, it is necessary to:
+             (+++) Configure the EXTI Line 17 to be sensitive to rising edges (Interrupt
+                   or Event modes) and Enable the RTC Alarm Interrupt using the HAL_RTC_SetAlarm_IT()
+                   function
+             (+++) Configure the RTC to generate the RTC alarm using the HAL_RTC_Init()
+                   and HAL_RTC_SetTime() functions.
+        (++) To wake up from the Stop mode with an RTC Tamper or time stamp event, it
+             is necessary to:
+             (+++) Configure the EXTI Line 19 to be sensitive to rising edges (Interrupt or Event modes) and
+                   Enable the RTC Tamper or time stamp Interrupt using the HAL_RTCEx_SetTamper_IT()
+                   or HAL_RTCEx_SetTimeStamp_IT() functions.
+        (++) To wake up from the Stop mode with an RTC WakeUp event, it is necessary to:
+             (+++) Configure the EXTI Line 20 to be sensitive to rising edges (Interrupt or Event modes) and
+                   Enable the RTC WakeUp Interrupt using the HAL_RTCEx_SetWakeUpTimer_IT() function.
+             (+++) Configure the RTC to generate the RTC WakeUp event using the HAL_RTCEx_SetWakeUpTimer()
+                   function.
+
+    (+) RTC auto-wakeup (AWU) from the Standby mode
+        (++) To wake up from the Standby mode with an RTC alarm event, it is necessary to:
+             (+++) Enable the RTC Alarm Interrupt using the HAL_RTC_SetAlarm_IT() function.
+             (+++) Configure the RTC to generate the RTC alarm using the HAL_RTC_Init()
+                   and HAL_RTC_SetTime() functions.
+        (++) To wake up from the Standby mode with an RTC Tamper or time stamp event, it
+             is necessary to:
+             (+++) Enable the RTC Tamper or time stamp Interrupt and Configure the RTC to
+                   detect the tamper or time stamp event using the HAL_RTCEx_SetTimeStamp_IT()
+                   or HAL_RTCEx_SetTamper_IT()functions.
+        (++) To wake up from the Standby mode with an RTC WakeUp event, it is necessary to:
+             (+++) Enable the RTC WakeUp Interrupt and Configure the RTC to generate the RTC WakeUp event
+                   using the HAL_RTCEx_SetWakeUpTimer_IT() and HAL_RTCEx_SetWakeUpTimer() functions.
+
+    (+) Comparator auto-wakeup (AWU) from the Stop mode
+        (++) To wake up from the Stop mode with an comparator 1 or comparator 2 wakeup
+             event, it is necessary to:
+             (+++) Configure the EXTI Line 21 or EXTI Line 22 for comparator to be sensitive to to the
+                   selected edges (falling, rising or falling and rising) (Interrupt or Event modes) using
+                   the COMP functions.
+             (+++) Configure the comparator to generate the event.

+
+      (#) HSI (high-speed internal), 16 MHz factory-trimmed RC used directly or through
+          the PLL as System clock source.
+      (#) LSI (low-speed internal), ~37 KHz low consumption RC used as IWDG and/or RTC
+          clock source.
+
+      (#) HSE (high-speed external), 1 to 24 MHz crystal oscillator used directly or
+          through the PLL as System clock source. Can be used also as RTC clock source.
+
+      (#) LSE (low-speed external), 32 KHz oscillator used as RTC clock source.
+
+      (#) PLL (clocked by HSI or HSE), featuring different output clocks:
+        (++) The first output is used to generate the high speed system clock (up to 32 MHz)
+        (++) The second output is used to generate the clock for the USB OTG FS (48 MHz)
+
+      (#) CSS (Clock security system), once enable using the macro __HAL_RCC_CSS_ENABLE()
+          and if a HSE clock failure occurs(HSE used directly or through PLL as System
+          clock source), the System clocks automatically switched to MSI and an interrupt

+      (#) Several clock sources can be used to drive the System clock (SYSCLK): MSI, HSI,
+          HSE and PLL.

+          prescaler and used to clock the CPU, memory and peripherals mapped
+          on AHB bus (DMA, GPIO...). APB1 (PCLK1) and APB2 (PCLK2) clocks are derived

+ ===============================================================================
+                          ##### RTC Operating Condition #####
+ ===============================================================================
+  [..] The real-time clock (RTC) and the RTC backup registers can be powered
+       from the VBAT voltage when the main VDD supply is powered off.
+       To retain the content of the RTC backup registers and supply the RTC
+       when VDD is turned off, VBAT pin can be connected to an optional
+       standby voltage supplied by a battery or by another source.
+
+  [..] To allow the RTC operating even when the main digital supply (VDD) is turned
+       off, the VBAT pin powers the following blocks:
+    (#) The RTC
+    (#) The LSE oscillator
+    (#) PC13 to PC15 I/Os (when available)
+
+  [..] When the backup domain is supplied by VDD (analog switch connected to VDD),
+       the following pins are available:
+    (#) PC14 and PC15 can be used as either GPIO or LSE pins
+    (#) PC13 can be used as a GPIO or as the RTC_AF1 pin
+
+  [..] When the backup domain is supplied by VBAT (analog switch connected to VBAT
+       because VDD is not present), the following pins are available:
+    (#) PC14 and PC15 can be used as LSE pins only
+    (#) PC13 can be used as the RTC_AF1 pin
+
+                   ##### Backup Domain Reset #####
+ ===============================================================================
+  [..] The backup domain reset sets all RTC registers and the RCC_BDCR register
+       to their reset values.
+  [..] A backup domain reset is generated when one of the following events occurs:
+    (#) Software reset, triggered by setting the BDRST bit in the
+        RCC Backup domain control register (RCC_BDCR).
+    (#) VDD or VBAT power on, if both supplies have previously been powered off.
+
+                   ##### Backup Domain Access #####
+ ===================================================================
+  [..] After reset, the backup domain (RTC registers, RTC backup data
+       registers and backup SRAM) is protected against possible unwanted write
+       accesses.
+  [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
+    (+) Enable the Power Controller (PWR) APB1 interface clock using the
+        __HAL_RCC_PWR_CLK_ENABLE() function.
+    (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
+    (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
+    (+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function.
+
+
+                  ##### How to use RTC Driver #####
+ ===================================================================
+  [..]
+    (+) Enable the RTC domain access (see description in the section above).
+    (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
+        format using the HAL_RTC_Init() function.
+
+  *** Time and Date configuration ***
+  ===================================
+  [..]
+    (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime()
+        and HAL_RTC_SetDate() functions.
+    (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions.
+
+  *** Alarm configuration ***
+  ===========================
+  [..]
+    (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function.
+            You can also configure the RTC Alarm with interrupt mode using the
+            HAL_RTC_SetAlarm_IT() function.
+    (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
+
+                  ##### RTC and low power modes #####
+  ==================================================================
+  [..] The MCU can be woken up from a low power mode by an RTC alternate
+       function.
+  [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
+       RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
+       These RTC alternate functions can wake up the system from the Stop and
+       Standby low power modes.
+  [..] The system can also wake up from low power modes without depending
+       on an external interrupt (Auto-wakeup mode), by using the RTC alarm
+       or the RTC wakeup events.
+  [..] The RTC provides a programmable time base for waking up from the
+       Stop or Standby mode at regular intervals.
+       Wakeup from STOP and STANDBY modes is possible only when the RTC clock source
+       is LSE or LSI.
+
+  *** Callback registration ***
+  =============================================
+
+  The compilation define  USE_RTC_REGISTER_CALLBACKS when set to 1
+  allows the user to configure dynamically the driver callbacks.
+  Use Function @ref HAL_RTC_RegisterCallback() to register an interrupt callback.
+
+  Function @ref HAL_RTC_RegisterCallback() allows to register following callbacks:
+    (+) AlarmAEventCallback          : RTC Alarm A Event callback.
+    (+) AlarmBEventCallback          : RTC Alarm B Event callback.
+    (+) TimeStampEventCallback       : RTC TimeStamp Event callback.
+    (+) WakeUpTimerEventCallback     : RTC WakeUpTimer Event callback.
+    (+) Tamper1EventCallback         : RTC Tamper 1 Event callback.
+    (+) Tamper2EventCallback         : RTC Tamper 2 Event callback.
+    (+) Tamper3EventCallback         : RTC Tamper 3 Event callback.
+    (+) MspInitCallback              : RTC MspInit callback.
+    (+) MspDeInitCallback            : RTC MspDeInit callback.
+  This function takes as parameters the HAL peripheral handle, the Callback ID
+  and a pointer to the user callback function.
+
+  Use function @ref HAL_RTC_UnRegisterCallback() to reset a callback to the default
+  weak function.
+  @ref HAL_RTC_UnRegisterCallback() takes as parameters the HAL peripheral handle,
+  and the Callback ID.
+  This function allows to reset following callbacks:
+    (+) AlarmAEventCallback          : RTC Alarm A Event callback.
+    (+) AlarmBEventCallback          : RTC Alarm B Event callback.
+    (+) TimeStampEventCallback       : RTC TimeStamp Event callback.
+    (+) WakeUpTimerEventCallback     : RTC WakeUpTimer Event callback.
+    (+) Tamper1EventCallback         : RTC Tamper 1 Event callback.
+    (+) Tamper2EventCallback         : RTC Tamper 2 Event callback.
+    (+) Tamper3EventCallback         : RTC Tamper 3 Event callback.
+    (+) MspInitCallback              : RTC MspInit callback.
+    (+) MspDeInitCallback            : RTC MspDeInit callback.
+
+  By default, after the @ref HAL_RTC_Init() and when the state is HAL_RTC_STATE_RESET,
+  all callbacks are set to the corresponding weak functions :
+  examples @ref AlarmAEventCallback(), @ref WakeUpTimerEventCallback().
+  Exception done for MspInit and MspDeInit callbacks that are reset to the legacy weak function
+  in the @ref HAL_RTC_Init()/@ref HAL_RTC_DeInit() only when these callbacks are null
+  (not registered beforehand).
+  If not, MspInit or MspDeInit are not null, @ref HAL_RTC_Init()/@ref HAL_RTC_DeInit()
+  keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
+
+  Callbacks can be registered/unregistered in HAL_RTC_STATE_READY state only.
+  Exception done MspInit/MspDeInit that can be registered/unregistered
+  in HAL_RTC_STATE_READY or HAL_RTC_STATE_RESET state,
+  thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
+  In that case first register the MspInit/MspDeInit user callbacks
+  using @ref HAL_RTC_RegisterCallback() before calling @ref HAL_RTC_DeInit()
+  or @ref HAL_RTC_Init() function.
+
+  When The compilation define USE_HAL_RTC_REGISTER_CALLBACKS is set to 0 or
+  not defined, the callback registration feature is not available and all callbacks
+  are set to the corresponding weak functions.

+ ===============================================================================
+   [..] This section provides functions allowing to initialize and configure the
+         RTC Prescaler (Synchronous and Asynchronous), RTC Hour format, disable
+         RTC registers Write protection, enter and exit the RTC initialization mode,
+         RTC registers synchronization check and reference clock detection enable.
+         (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base.
+             It is split into 2 programmable prescalers to minimize power consumption.
+             (++) A 7-bit asynchronous prescaler and a 13-bit synchronous prescaler.
+             (++) When both prescalers are used, it is recommended to configure the
+                 asynchronous prescaler to a high value to minimize power consumption.
+         (#) All RTC registers are Write protected. Writing to the RTC registers
+             is enabled by writing a key into the Write Protection register, RTC_WPR.
+         (#) To configure the RTC Calendar, user application should enter
+             initialization mode. In this mode, the calendar counter is stopped
+             and its value can be updated. When the initialization sequence is
+             complete, the calendar restarts counting after 4 RTCCLK cycles.
+         (#) To read the calendar through the shadow registers after Calendar
+             initialization, calendar update or after wakeup from low power modes
+             the software must first clear the RSF flag. The software must then
+             wait until it is set again before reading the calendar, which means
+             that the calendar registers have been correctly copied into the
+             RTC_TR and RTC_DR shadow registers.The HAL_RTC_WaitForSynchro() function
+             implements the above software sequence (RSF clear and RSF check).

+  * @brief   Extended RTC HAL module driver.
+  *          This file provides firmware functions to manage the following
+  *          functionalities of the Real Time Clock (RTC) Extended peripheral:
+  *           + RTC Time Stamp functions
+  *           + RTC Tamper functions
+  *           + RTC Wake-up functions
+  *           + Extended Control functions
+  *           + Extended RTC features functions
+  *
+  @verbatim
+  ==============================================================================
+                  ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    (+) Enable the RTC domain access.
+    (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
+        format using the HAL_RTC_Init() function.
+
+  *** RTC Wakeup configuration ***
+  ================================
+  [..]
+    (+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTCEx_SetWakeUpTimer()
+        function. You can also configure the RTC Wakeup timer with interrupt mode
+        using the HAL_RTCEx_SetWakeUpTimer_IT() function.
+    (+) To read the RTC WakeUp Counter register, use the HAL_RTCEx_GetWakeUpTimer()
+        function.
+
+  *** TimeStamp configuration ***
+  ===============================
+  [..]
+    (+) Configure the RTC_AFx trigger and enable the RTC TimeStamp using the
+        HAL_RTCEx_SetTimeStamp() function. You can also configure the RTC TimeStamp with
+        interrupt mode using the HAL_RTCEx_SetTimeStamp_IT() function.
+    (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTCEx_GetTimeStamp()
+        function.
+    (+) The TIMESTAMP alternate function can be mapped to RTC_AF1 (PC13).
+
+  *** Tamper configuration ***
+  ============================
+  [..]
+    (+) Enable the RTC Tamper and configure the Tamper filter count, trigger Edge
+        or Level according to the Tamper filter (if equal to 0 Edge else Level)
+        value, sampling frequency, precharge or discharge and Pull-UP using the
+        HAL_RTCEx_SetTamper() function. You can configure RTC Tamper with interrupt
+        mode using HAL_RTCEx_SetTamper_IT() function.
+    (+) The TAMPER1 alternate function can be mapped to RTC_AF1 (PC13).
+
+  *** Backup Data Registers configuration ***
+  ===========================================
+  [..]
+    (+) To write to the RTC Backup Data registers, use the HAL_RTCEx_BKUPWrite()
+        function.
+    (+) To read the RTC Backup Data registers, use the HAL_RTCEx_BKUPRead()
+        function.

+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    This driver implements a high level communication layer for read and write from/to
+    this memory. The needed STM32 hardware resources (SDIO and GPIO) are performed by
+    the user in HAL_SD_MspInit() function (MSP layer).
+    Basically, the MSP layer configuration should be the same as we provide in the
+    examples.
+    You can easily tailor this configuration according to hardware resources.
+
+  [..]
+    This driver is a generic layered driver for SDIO memories which uses the HAL
+    SDIO driver functions to interface with SD and uSD cards devices.
+    It is used as follows:
+
+    (#)Initialize the SDIO low level resources by implementing the HAL_SD_MspInit() API:
+        (##) Enable the SDIO interface clock using __HAL_RCC_SDIO_CLK_ENABLE();
+        (##) SDIO pins configuration for SD card
+            (+++) Enable the clock for the SDIO GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE();
+            (+++) Configure these SDIO pins as alternate function pull-up using HAL_GPIO_Init()
+                  and according to your pin assignment;
+        (##) DMA configuration if you need to use DMA process (HAL_SD_ReadBlocks_DMA()
+             and HAL_SD_WriteBlocks_DMA() APIs).
+            (+++) Enable the DMAx interface clock using __HAL_RCC_DMAx_CLK_ENABLE();
+            (+++) Configure the DMA using the function HAL_DMA_Init() with predeclared and filled.
+        (##) NVIC configuration if you need to use interrupt process when using DMA transfer.
+            (+++) Configure the SDIO and DMA interrupt priorities using functions
+                  HAL_NVIC_SetPriority(); DMA priority is superior to SDIO's priority
+            (+++) Enable the NVIC DMA and SDIO IRQs using function HAL_NVIC_EnableIRQ()
+            (+++) SDIO interrupts are managed using the macros __HAL_SD_ENABLE_IT()
+                  and __HAL_SD_DISABLE_IT() inside the communication process.
+            (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_GET_IT()
+                  and __HAL_SD_CLEAR_IT()
+        (##) NVIC configuration if you need to use interrupt process (HAL_SD_ReadBlocks_IT()
+             and HAL_SD_WriteBlocks_IT() APIs).
+            (+++) Configure the SDIO interrupt priorities using function HAL_NVIC_SetPriority();
+            (+++) Enable the NVIC SDIO IRQs using function HAL_NVIC_EnableIRQ()
+            (+++) SDIO interrupts are managed using the macros __HAL_SD_ENABLE_IT()
+                  and __HAL_SD_DISABLE_IT() inside the communication process.
+            (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_GET_IT()
+                  and __HAL_SD_CLEAR_IT()
+    (#) At this stage, you can perform SD read/write/erase operations after SD card initialization
+
+
+  *** SD Card Initialization and configuration ***
+  ================================================
+  [..]
+    To initialize the SD Card, use the HAL_SD_Init() function. It Initializes
+    SDIO Peripheral(STM32 side) and the SD Card, and put it into StandBy State (Ready for data transfer).
+    This function provide the following operations:
+
+    (#) Apply the SD Card initialization process at 400KHz and check the SD Card
+        type (Standard Capacity or High Capacity). You can change or adapt this
+        frequency by adjusting the "ClockDiv" field.
+        The SD Card frequency (SDIO_CK) is computed as follows:
+
+           SDIO_CK = SDIOCLK / (ClockDiv + 2)
+
+        In initialization mode and according to the SD Card standard,
+        make sure that the SDIO_CK frequency doesn't exceed 400KHz.
+
+        This phase of initialization is done through SDIO_Init() and
+        SDIO_PowerState_ON() SDIO low level APIs.
+
+    (#) Initialize the SD card. The API used is HAL_SD_InitCard().
+        This phase allows the card initialization and identification
+        and check the SD Card type (Standard Capacity or High Capacity)
+        The initialization flow is compatible with SD standard.
+
+        This API (HAL_SD_InitCard()) could be used also to reinitialize the card in case
+        of plug-off plug-in.
+
+    (#) Configure the SD Card Data transfer frequency. You can change or adapt this
+        frequency by adjusting the "ClockDiv" field.
+        In transfer mode and according to the SD Card standard, make sure that the
+        SDIO_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
+        To be able to use a frequency higher than 24MHz, you should use the SDIO
+        peripheral in bypass mode. Refer to the corresponding reference manual
+        for more details.
+
+    (#) Select the corresponding SD Card according to the address read with the step 2.
+
+    (#) Configure the SD Card in wide bus mode: 4-bits data.
+
+  *** SD Card Read operation ***
+  ==============================
+  [..]
+    (+) You can read from SD card in polling mode by using function HAL_SD_ReadBlocks().
+        This function support only 512-bytes block length (the block size should be
+        chosen as 512 bytes).
+        You can choose either one block read operation or multiple block read operation
+        by adjusting the "NumberOfBlocks" parameter.
+        After this, you have to ensure that the transfer is done correctly. The check is done
+        through HAL_SD_GetCardState() function for SD card state.
+
+    (+) You can read from SD card in DMA mode by using function HAL_SD_ReadBlocks_DMA().
+        This function support only 512-bytes block length (the block size should be
+        chosen as 512 bytes).
+        You can choose either one block read operation or multiple block read operation
+        by adjusting the "NumberOfBlocks" parameter.
+        After this, you have to ensure that the transfer is done correctly. The check is done
+        through HAL_SD_GetCardState() function for SD card state.
+        You could also check the DMA transfer process through the SD Rx interrupt event.
+
+    (+) You can read from SD card in Interrupt mode by using function HAL_SD_ReadBlocks_IT().
+        This function support only 512-bytes block length (the block size should be

+
+  *** SD card information ***
+  ===========================
+  [..]
+    (+) To get SD card information, you can use the function HAL_SD_GetCardInfo().

+    (+) __HAL_SD_GET_FLAG:Check whether the specified SD flag is set or not
+    (+) __HAL_SD_CLEAR_FLAG: Clear the SD's pending flags
+
+    (@) You can refer to the SD HAL driver header file for more useful macros
+
+  *** Callback registration ***
+  =============================================
+  [..]
+    The compilation define USE_HAL_SD_REGISTER_CALLBACKS when set to 1
+    allows the user to configure dynamically the driver callbacks.
+
+    Use Functions @ref HAL_SD_RegisterCallback() to register a user callback,
+    it allows to register following callbacks:
+      (+) TxCpltCallback : callback when a transmission transfer is completed.
+      (+) RxCpltCallback : callback when a reception transfer is completed.
+      (+) ErrorCallback : callback when error occurs.
+      (+) AbortCpltCallback : callback when abort is completed.
+      (+) MspInitCallback    : SD MspInit.
+      (+) MspDeInitCallback  : SD MspDeInit.
+    This function takes as parameters the HAL peripheral handle, the Callback ID
+    and a pointer to the user callback function.
+
+    Use function @ref HAL_SD_UnRegisterCallback() to reset a callback to the default
+    weak (surcharged) function. It allows to reset following callbacks:
+      (+) TxCpltCallback : callback when a transmission transfer is completed.
+      (+) RxCpltCallback : callback when a reception transfer is completed.
+      (+) ErrorCallback : callback when error occurs.
+      (+) AbortCpltCallback : callback when abort is completed.
+      (+) MspInitCallback    : SD MspInit.
+      (+) MspDeInitCallback  : SD MspDeInit.
+    This function) takes as parameters the HAL peripheral handle and the Callback ID.
+
+    By default, after the @ref HAL_SD_Init and if the state is HAL_SD_STATE_RESET
+    all callbacks are reset to the corresponding legacy weak (surcharged) functions.
+    Exception done for MspInit and MspDeInit callbacks that are respectively
+    reset to the legacy weak (surcharged) functions in the @ref HAL_SD_Init
+    and @ref  HAL_SD_DeInit only when these callbacks are null (not registered beforehand).
+    If not, MspInit or MspDeInit are not null, the @ref HAL_SD_Init and @ref HAL_SD_DeInit
+    keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
+
+    Callbacks can be registered/unregistered in READY state only.
+    Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
+    in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
+    during the Init/DeInit.
+    In that case first register the MspInit/MspDeInit user callbacks
+    using @ref HAL_SD_RegisterCallback before calling @ref HAL_SD_DeInit
+    or @ref HAL_SD_Init function.
+
+    When The compilation define USE_HAL_SD_REGISTER_CALLBACKS is set to 0 or
+    not defined, the callback registering feature is not available
+    and weak (surcharged) callbacks are used.

+  @verbatim
+  ==============================================================================
+                     ##### How to use this driver #####
+  ==============================================================================
+    [..]
+      The SMARTCARD HAL driver can be used as follows:
+
+    (#) Declare a SMARTCARD_HandleTypeDef handle structure.
+    (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
+        (##) Enable the interface clock of the USARTx associated to the SMARTCARD.
+        (##) SMARTCARD pins configuration:
+            (+++) Enable the clock for the SMARTCARD GPIOs.
+            (+++) Configure SMARTCARD pins as alternate function pull-up.
+        (##) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
+             and HAL_SMARTCARD_Receive_IT() APIs):
+            (+++) Configure the USARTx interrupt priority.
+            (+++) Enable the NVIC USART IRQ handle.
+        (##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
+             and HAL_SMARTCARD_Receive_DMA() APIs):
+            (+++) Declare a DMA handle structure for the Tx/Rx channel.
+            (+++) Enable the DMAx interface clock.
+            (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
+            (+++) Configure the DMA Tx/Rx channel.
+            (+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
+            (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
+            (+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle
+                  (used for last byte sending completion detection in DMA non circular mode)
+
+    (#) Program the Baud Rate, Word Length , Stop Bit, Parity, Hardware
+        flow control and Mode(Receiver/Transmitter) in the SMARTCARD Init structure.
+
+    (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
+        (++) These APIs configure also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+             by calling the customized HAL_SMARTCARD_MspInit() API.
+    [..]
+    (@) The specific SMARTCARD interrupts (Transmission complete interrupt,
+        RXNE interrupt and Error Interrupts) will be managed using the macros
+        __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
+
+    [..]
+    Three operation modes are available within this driver :
+
+    *** Polling mode IO operation ***
+    =================================
+    [..]
+      (+) Send an amount of data in blocking mode using HAL_SMARTCARD_Transmit()
+      (+) Receive an amount of data in blocking mode using HAL_SMARTCARD_Receive()
+
+    *** Interrupt mode IO operation ***
+    ===================================
+    [..]
+      (+) Send an amount of data in non blocking mode using HAL_SMARTCARD_Transmit_IT()
+      (+) At transmission end of transfer HAL_SMARTCARD_TxCpltCallback is executed and user can
+          add his own code by customization of function pointer HAL_SMARTCARD_TxCpltCallback
+      (+) Receive an amount of data in non blocking mode using HAL_SMARTCARD_Receive_IT()
+      (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback is executed and user can

+    ========================================
+    [..]

+
+      (+) __HAL_SMARTCARD_ENABLE: Enable the SMARTCARD peripheral
+      (+) __HAL_SMARTCARD_DISABLE: Disable the SMARTCARD peripheral
+      (+) __HAL_SMARTCARD_GET_FLAG : Check whether the specified SMARTCARD flag is set or not
+      (+) __HAL_SMARTCARD_CLEAR_FLAG : Clear the specified SMARTCARD pending flag
+      (+) __HAL_SMARTCARD_ENABLE_IT: Enable the specified SMARTCARD interrupt
+      (+) __HAL_SMARTCARD_DISABLE_IT: Disable the specified SMARTCARD interrupt
+
+    [..]
+      (@) You can refer to the SMARTCARD HAL driver header file for more useful macros
+
+    ##### Callback registration #####
+    ==================================
+
+    [..]
+    The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS when set to 1
+    allows the user to configure dynamically the driver callbacks.
+
+    [..]
+    Use Function @ref HAL_SMARTCARD_RegisterCallback() to register a user callback.
+    Function @ref HAL_SMARTCARD_RegisterCallback() allows to register following callbacks:
+    (+) TxCpltCallback            : Tx Complete Callback.
+    (+) RxCpltCallback            : Rx Complete Callback.
+    (+) ErrorCallback             : Error Callback.
+    (+) AbortCpltCallback         : Abort Complete Callback.
+    (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
+    (+) AbortReceiveCpltCallback  : Abort Receive Complete Callback.
+    (+) MspInitCallback           : SMARTCARD MspInit.
+    (+) MspDeInitCallback         : SMARTCARD MspDeInit.
+    This function takes as parameters the HAL peripheral handle, the Callback ID
+    and a pointer to the user callback function.
+
+    [..]
+    Use function @ref HAL_SMARTCARD_UnRegisterCallback() to reset a callback to the default
+    weak (surcharged) function.
+    @ref HAL_SMARTCARD_UnRegisterCallback() takes as parameters the HAL peripheral handle,
+    and the Callback ID.
+    This function allows to reset following callbacks:
+    (+) TxCpltCallback            : Tx Complete Callback.
+    (+) RxCpltCallback            : Rx Complete Callback.
+    (+) ErrorCallback             : Error Callback.
+    (+) AbortCpltCallback         : Abort Complete Callback.
+    (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
+    (+) AbortReceiveCpltCallback  : Abort Receive Complete Callback.
+    (+) MspInitCallback           : SMARTCARD MspInit.
+    (+) MspDeInitCallback         : SMARTCARD MspDeInit.
+
+    [..]
+    By default, after the @ref HAL_SMARTCARD_Init() and when the state is HAL_SMARTCARD_STATE_RESET
+    all callbacks are set to the corresponding weak (surcharged) functions:
+    examples @ref HAL_SMARTCARD_TxCpltCallback(), @ref HAL_SMARTCARD_RxCpltCallback().
+    Exception done for MspInit and MspDeInit functions that are respectively
+    reset to the legacy weak (surcharged) functions in the @ref HAL_SMARTCARD_Init()
+    and @ref HAL_SMARTCARD_DeInit() only when these callbacks are null (not registered beforehand).
+    If not, MspInit or MspDeInit are not null, the @ref HAL_SMARTCARD_Init() and @ref HAL_SMARTCARD_DeInit()
+    keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
+
+    [..]
+    Callbacks can be registered/unregistered in HAL_SMARTCARD_STATE_READY state only.
+    Exception done MspInit/MspDeInit that can be registered/unregistered
+    in HAL_SMARTCARD_STATE_READY or HAL_SMARTCARD_STATE_RESET state, thus registered (user)
+    MspInit/DeInit callbacks can be used during the Init/DeInit.
+    In that case first register the MspInit/MspDeInit user callbacks
+    using @ref HAL_SMARTCARD_RegisterCallback() before calling @ref HAL_SMARTCARD_DeInit()
+    or @ref HAL_SMARTCARD_Init() function.
+
+    [..]
+    When The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS is set to 0 or
+    not defined, the callback registration feature is not available
+    and weak (surcharged) callbacks are used.

+  ==============================================================================
+  [..]
+  This subsection provides a set of functions allowing to initialize the USART
+  in Smartcard mode.
+  [..]
+  The Smartcard interface is designed to support asynchronous protocol Smartcards as
+  defined in the ISO 7816-3 standard.
+  [..]
+  The USART can provide a clock to the smartcard through the SCLK output.
+  In smartcard mode, SCLK is not associated to the communication but is simply derived
+  from the internal peripheral input clock through a 5-bit prescaler.
+  [..]
+  (+) For the Smartcard mode only these parameters can be configured:
+      (++) Baud Rate
+      (++) Word Length => Should be 9 bits (8 bits + parity)
+      (++) Stop Bit
+      (++) Parity: => Should be enabled
+      (++) USART polarity
+      (++) USART phase
+      (++) USART LastBit
+      (++) Receiver/transmitter modes
+      (++) Prescaler
+      (++) GuardTime
+      (++) NACKState: The Smartcard NACK state
+
+     (+) Recommended SmartCard interface configuration to get the Answer to Reset from the Card:
+        (++) Word Length = 9 Bits
+        (++) 1.5 Stop Bit
+        (++) Even parity
+        (++) BaudRate = 12096 baud
+        (++) Tx and Rx enabled
+  [..]
+  Please refer to the ISO 7816-3 specification for more details.
+
+  [..]
+   (@) It is also possible to choose 0.5 stop bit for receiving but it is recommended
+       to use 1.5 stop bits for both transmitting and receiving to avoid switching
+       between the two configurations.
+  [..]
+    The HAL_SMARTCARD_Init() function follows the USART  SmartCard configuration
+    procedures (details for the procedures are available in reference manual (RM0038)).
+
+@endverbatim
+
+  The SMARTCARD frame format is given in the following table:
+       +-------------------------------------------------------------+
+       |   M bit |  PCE bit  |        SMARTCARD frame                |
+       |---------------------|---------------------------------------|
+       |    1    |    1      |    | SB | 8 bit data | PB | STB |     |

+ ===============================================================================
+                      ##### IO operation functions #####
+ ===============================================================================
+ [..]
+   This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
+
+ [..]
+    (#) Smartcard is a single wire half duplex communication protocol.
+    The Smartcard interface is designed to support asynchronous protocol Smartcards as
+    defined in the ISO 7816-3 standard.
+    (#) The USART should be configured as:
+       (++) 8 bits plus parity: where M=1 and PCE=1 in the USART_CR1 register
+       (++) 1.5 stop bits when transmitting and receiving: where STOP=11 in the USART_CR2 register.
+
+    (#) There are two modes of transfer:
+       (++) Blocking mode: The communication is performed in polling mode.
+            The HAL status of all data processing is returned by the same function
+            after finishing transfer.
+       (++) Non Blocking mode: The communication is performed using Interrupts
+           or DMA, These APIs return the HAL status.
+           The end of the data processing will be indicated through the
+           dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
+           using DMA mode.
+           The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
+           will be executed respectively at the end of the Transmit or Receive process
+           The HAL_SMARTCARD_ErrorCallback() user callback will be executed when a communication error is detected
+
+    (#) Blocking mode APIs are :
+        (++) HAL_SMARTCARD_Transmit()
+        (++) HAL_SMARTCARD_Receive()
+
+    (#) Non Blocking mode APIs with Interrupt are :
+        (++) HAL_SMARTCARD_Transmit_IT()
+        (++) HAL_SMARTCARD_Receive_IT()
+        (++) HAL_SMARTCARD_IRQHandler()
+
+    (#) Non Blocking mode functions with DMA are :
+        (++) HAL_SMARTCARD_Transmit_DMA()
+        (++) HAL_SMARTCARD_Receive_DMA()
+
+    (#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
+        (++) HAL_SMARTCARD_TxCpltCallback()
+        (++) HAL_SMARTCARD_RxCpltCallback()
+        (++) HAL_SMARTCARD_ErrorCallback()
+
+    (#) Non-Blocking mode transfers could be aborted using Abort API's :
+        (+) HAL_SMARTCARD_Abort()
+        (+) HAL_SMARTCARD_AbortTransmit()
+        (+) HAL_SMARTCARD_AbortReceive()
+        (+) HAL_SMARTCARD_Abort_IT()
+        (+) HAL_SMARTCARD_AbortTransmit_IT()
+        (+) HAL_SMARTCARD_AbortReceive_IT()
+
+    (#) For Abort services based on interrupts (HAL_SMARTCARD_Abortxxx_IT), a set of Abort Complete Callbacks are provided:
+        (+) HAL_SMARTCARD_AbortCpltCallback()
+        (+) HAL_SMARTCARD_AbortTransmitCpltCallback()
+        (+) HAL_SMARTCARD_AbortReceiveCpltCallback()
+
+    (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
+        Errors are handled as follows :
+       (+) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
+           to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
+           Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
+           and HAL_SMARTCARD_ErrorCallback() user callback is executed. Transfer is kept ongoing on SMARTCARD side.
+           If user wants to abort it, Abort services should be called by user.
+       (+) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
+           This concerns Frame Error in Interrupt mode tranmission, Overrun Error in Interrupt mode reception and all errors in DMA mode.
+           Error code is set to allow user to identify error type, and HAL_SMARTCARD_ErrorCallback() user callback is executed.

+  ==============================================================================
+                        ##### How to use this driver #####
+  ==============================================================================
+    [..]
+      The SPI HAL driver can be used as follows:
+
+      (#) Declare a SPI_HandleTypeDef handle structure, for example:
+          SPI_HandleTypeDef  hspi;
+
+      (#)Initialize the SPI low level resources by implementing the HAL_SPI_MspInit() API:
+          (##) Enable the SPIx interface clock
+          (##) SPI pins configuration
+              (+++) Enable the clock for the SPI GPIOs
+              (+++) Configure these SPI pins as alternate function push-pull
+          (##) NVIC configuration if you need to use interrupt process
+              (+++) Configure the SPIx interrupt priority
+              (+++) Enable the NVIC SPI IRQ handle
+          (##) DMA Configuration if you need to use DMA process
+              (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive Stream/Channel
+              (+++) Enable the DMAx clock
+              (+++) Configure the DMA handle parameters
+              (+++) Configure the DMA Tx or Rx Stream/Channel
+              (+++) Associate the initialized hdma_tx(or _rx)  handle to the hspi DMA Tx or Rx handle
+              (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream/Channel
+
+      (#) Program the Mode, BidirectionalMode , Data size, Baudrate Prescaler, NSS
+          management, Clock polarity and phase, FirstBit and CRC configuration in the hspi Init structure.
+
+      (#) Initialize the SPI registers by calling the HAL_SPI_Init() API:
+          (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+              by calling the customized HAL_SPI_MspInit() API.
+     [..]
+       Circular mode restriction:
+      (#) The DMA circular mode cannot be used when the SPI is configured in these modes:
+          (##) Master 2Lines RxOnly
+          (##) Master 1Line Rx
+      (#) The CRC feature is not managed when the DMA circular mode is enabled
+      (#) When the SPI DMA Pause/Stop features are used, we must use the following APIs
+          the HAL_SPI_DMAPause()/ HAL_SPI_DMAStop() only under the SPI callbacks
+     [..]
+       Master Receive mode restriction:
+      (#) In Master unidirectional receive-only mode (MSTR =1, BIDIMODE=0, RXONLY=1) or
+          bidirectional receive mode (MSTR=1, BIDIMODE=1, BIDIOE=0), to ensure that the SPI
+          does not initiate a new transfer the following procedure has to be respected:
+          (##) HAL_SPI_DeInit()
+          (##) HAL_SPI_Init()
+     [..]
+       Callback registration:
+
+      (#) The compilation flag USE_HAL_SPI_REGISTER_CALLBACKS when set to 1U
+          allows the user to configure dynamically the driver callbacks.
+          Use Functions HAL_SPI_RegisterCallback() to register an interrupt callback.
+
+          Function HAL_SPI_RegisterCallback() allows to register following callbacks:
+            (+) TxCpltCallback        : SPI Tx Completed callback
+            (+) RxCpltCallback        : SPI Rx Completed callback
+            (+) TxRxCpltCallback      : SPI TxRx Completed callback
+            (+) TxHalfCpltCallback    : SPI Tx Half Completed callback
+            (+) RxHalfCpltCallback    : SPI Rx Half Completed callback
+            (+) TxRxHalfCpltCallback  : SPI TxRx Half Completed callback
+            (+) ErrorCallback         : SPI Error callback
+            (+) AbortCpltCallback     : SPI Abort callback
+            (+) MspInitCallback       : SPI Msp Init callback
+            (+) MspDeInitCallback     : SPI Msp DeInit callback
+          This function takes as parameters the HAL peripheral handle, the Callback ID
+          and a pointer to the user callback function.
+
+
+      (#) Use function HAL_SPI_UnRegisterCallback to reset a callback to the default
+          weak function.
+          HAL_SPI_UnRegisterCallback takes as parameters the HAL peripheral handle,
+          and the Callback ID.
+          This function allows to reset following callbacks:
+            (+) TxCpltCallback        : SPI Tx Completed callback
+            (+) RxCpltCallback        : SPI Rx Completed callback
+            (+) TxRxCpltCallback      : SPI TxRx Completed callback
+            (+) TxHalfCpltCallback    : SPI Tx Half Completed callback
+            (+) RxHalfCpltCallback    : SPI Rx Half Completed callback
+            (+) TxRxHalfCpltCallback  : SPI TxRx Half Completed callback
+            (+) ErrorCallback         : SPI Error callback
+            (+) AbortCpltCallback     : SPI Abort callback
+            (+) MspInitCallback       : SPI Msp Init callback
+            (+) MspDeInitCallback     : SPI Msp DeInit callback
+
+       By default, after the HAL_SPI_Init() and when the state is HAL_SPI_STATE_RESET
+       all callbacks are set to the corresponding weak functions:
+       examples HAL_SPI_MasterTxCpltCallback(), HAL_SPI_MasterRxCpltCallback().
+       Exception done for MspInit and MspDeInit functions that are
+       reset to the legacy weak functions in the HAL_SPI_Init()/ HAL_SPI_DeInit() only when
+       these callbacks are null (not registered beforehand).
+       If MspInit or MspDeInit are not null, the HAL_SPI_Init()/ HAL_SPI_DeInit()
+       keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
+
+       Callbacks can be registered/unregistered in HAL_SPI_STATE_READY state only.
+       Exception done MspInit/MspDeInit functions that can be registered/unregistered
+       in HAL_SPI_STATE_READY or HAL_SPI_STATE_RESET state,
+       thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
+       Then, the user first registers the MspInit/MspDeInit user callbacks
+       using HAL_SPI_RegisterCallback() before calling HAL_SPI_DeInit()
+       or HAL_SPI_Init() function.
+
+       When The compilation define USE_HAL_PPP_REGISTER_CALLBACKS is set to 0 or
+       not defined, the callback registering feature is not available
+       and weak (surcharged) callbacks are used.
+
+     [..]
+       Using the HAL it is not possible to reach all supported SPI frequency with the different SPI Modes,
+       the following table resume the max SPI frequency reached with data size 8bits/16bits,
+         according to frequency of the APBx Peripheral Clock (fPCLK) used by the SPI instance.

+    data transfers.
+
+    [..] The SPI supports master and slave mode :
+
+    (#) There are two modes of transfer:
+       (++) Blocking mode: The communication is performed in polling mode.
+            The HAL status of all data processing is returned by the same function
+            after finishing transfer.
+       (++) No-Blocking mode: The communication is performed using Interrupts
+            or DMA, These APIs return the HAL status.
+            The end of the data processing will be indicated through the
+            dedicated SPI IRQ when using Interrupt mode or the DMA IRQ when
+            using DMA mode.
+            The HAL_SPI_TxCpltCallback(), HAL_SPI_RxCpltCallback() and HAL_SPI_TxRxCpltCallback() user callbacks
+            will be executed respectively at the end of the transmit or Receive process
+            The HAL_SPI_ErrorCallback()user callback will be executed when a communication error is detected
+
+    (#) APIs provided for these 2 transfer modes (Blocking mode or Non blocking mode using either Interrupt or DMA)
+        exist for 1Line (simplex) and 2Lines (full duplex) modes.

+  ==============================================================================
+                          ##### How to use this driver #####
+  ==============================================================================  
+  [..]
+    This driver is a generic layered driver which contains a set of APIs used to 
+    control SRAM memories. It uses the FSMC layer functions to interface 
+    with SRAM devices.  
+    The following sequence should be followed to configure the FSMC to interface
+    with SRAM/PSRAM memories: 
+      
+   (#) Declare a SRAM_HandleTypeDef handle structure, for example:
+          SRAM_HandleTypeDef  hsram; and: 
+          
+       (++) Fill the SRAM_HandleTypeDef handle "Init" field with the allowed 
+            values of the structure member.
+            
+       (++) Fill the SRAM_HandleTypeDef handle "Instance" field with a predefined 
+            base register instance for NOR or SRAM device 
+                         
+       (++) Fill the SRAM_HandleTypeDef handle "Extended" field with a predefined
+            base register instance for NOR or SRAM extended mode 
+             
+   (#) Declare two FSMC_NORSRAM_TimingTypeDef structures, for both normal and extended 
+       mode timings; for example:
+          FSMC_NORSRAM_TimingTypeDef  Timing and FSMC_NORSRAM_TimingTypeDef  ExTiming;
+      and fill its fields with the allowed values of the structure member.
+      
+   (#) Initialize the SRAM Controller by calling the function HAL_SRAM_Init(). This function
+       performs the following sequence:
+          
+       (##) MSP hardware layer configuration using the function HAL_SRAM_MspInit()
+       (##) Control register configuration using the FSMC NORSRAM interface function 
+            FSMC_NORSRAM_Init()
+       (##) Timing register configuration using the FSMC NORSRAM interface function 
+            FSMC_NORSRAM_Timing_Init()
+       (##) Extended mode Timing register configuration using the FSMC NORSRAM interface function 
+            FSMC_NORSRAM_Extended_Timing_Init()
+       (##) Enable the SRAM device using the macro __FSMC_NORSRAM_ENABLE()    
+
+   (#) At this stage you can perform read/write accesses from/to the memory connected 
+       to the NOR/SRAM Bank. You can perform either polling or DMA transfer using the
+       following APIs:
+       (++) HAL_SRAM_Read()/HAL_SRAM_Write() for polling read/write access
+       (++) HAL_SRAM_Read_DMA()/HAL_SRAM_Write_DMA() for DMA read/write transfer
+       
+   (#) You can also control the SRAM device by calling the control APIs HAL_SRAM_WriteOperation_Enable()/
+       HAL_SRAM_WriteOperation_Disable() to respectively enable/disable the SRAM write operation  
+

+        (##) Enable the TIM interface clock using __HAL_RCC_TIMx_CLK_ENABLE();
+        (##) TIM pins configuration

+         internal clock from the APBx), using the following function:
+         HAL_TIM_ConfigClockSource, the clock configuration should be done before
+         any start function.
+
+     (#) Configure the TIM in the desired functioning mode using one of the

+       (++) HAL_TIM_Base_Init: to use the Timer to generate a simple time base
+       (++) HAL_TIM_OC_Init and HAL_TIM_OC_ConfigChannel: to use the Timer to generate an

+       (++) HAL_TIM_PWM_Init and HAL_TIM_PWM_ConfigChannel: to use the Timer to generate a
+            PWM signal.
+       (++) HAL_TIM_IC_Init and HAL_TIM_IC_ConfigChannel: to use the Timer to measure an
+            external signal.
+       (++) HAL_TIM_OnePulse_Init and HAL_TIM_OnePulse_ConfigChannel: to use the Timer
+            in One Pulse Mode.

+
+    *** Callback registration ***
+  =============================================
+
+  The compilation define  USE_HAL_TIM_REGISTER_CALLBACKS when set to 1
+  allows the user to configure dynamically the driver callbacks.
+
+  Use Function @ref HAL_TIM_RegisterCallback() to register a callback.
+  @ref HAL_TIM_RegisterCallback() takes as parameters the HAL peripheral handle,
+  the Callback ID and a pointer to the user callback function.
+
+  Use function @ref HAL_TIM_UnRegisterCallback() to reset a callback to the default
+  weak function.
+  @ref HAL_TIM_UnRegisterCallback takes as parameters the HAL peripheral handle,
+  and the Callback ID.
+
+  These functions allow to register/unregister following callbacks:
+    (+) Base_MspInitCallback              : TIM Base Msp Init Callback.
+    (+) Base_MspDeInitCallback            : TIM Base Msp DeInit Callback.
+    (+) IC_MspInitCallback                : TIM IC Msp Init Callback.
+    (+) IC_MspDeInitCallback              : TIM IC Msp DeInit Callback.
+    (+) OC_MspInitCallback                : TIM OC Msp Init Callback.
+    (+) OC_MspDeInitCallback              : TIM OC Msp DeInit Callback.
+    (+) PWM_MspInitCallback               : TIM PWM Msp Init Callback.
+    (+) PWM_MspDeInitCallback             : TIM PWM Msp DeInit Callback.
+    (+) OnePulse_MspInitCallback          : TIM One Pulse Msp Init Callback.
+    (+) OnePulse_MspDeInitCallback        : TIM One Pulse Msp DeInit Callback.
+    (+) Encoder_MspInitCallback           : TIM Encoder Msp Init Callback.
+    (+) Encoder_MspDeInitCallback         : TIM Encoder Msp DeInit Callback.
+    (+) PeriodElapsedCallback             : TIM Period Elapsed Callback.
+    (+) PeriodElapsedHalfCpltCallback     : TIM Period Elapsed half complete Callback.
+    (+) TriggerCallback                   : TIM Trigger Callback.
+    (+) TriggerHalfCpltCallback           : TIM Trigger half complete Callback.
+    (+) IC_CaptureCallback                : TIM Input Capture Callback.
+    (+) IC_CaptureHalfCpltCallback        : TIM Input Capture half complete Callback.
+    (+) OC_DelayElapsedCallback           : TIM Output Compare Delay Elapsed Callback.
+    (+) PWM_PulseFinishedCallback         : TIM PWM Pulse Finished Callback.
+    (+) PWM_PulseFinishedHalfCpltCallback : TIM PWM Pulse Finished half complete Callback.
+    (+) ErrorCallback                     : TIM Error Callback.
+
+By default, after the Init and when the state is HAL_TIM_STATE_RESET
+all interrupt callbacks are set to the corresponding weak functions:
+  examples @ref HAL_TIM_TriggerCallback(), @ref HAL_TIM_ErrorCallback().
+
+  Exception done for MspInit and MspDeInit functions that are reset to the legacy weak
+  functionalities in the Init / DeInit only when these callbacks are null
+  (not registered beforehand). If not, MspInit or MspDeInit are not null, the Init / DeInit
+    keep and use the user MspInit / MspDeInit callbacks(registered beforehand)
+
+    Callbacks can be registered / unregistered in HAL_TIM_STATE_READY state only.
+    Exception done MspInit / MspDeInit that can be registered / unregistered
+    in HAL_TIM_STATE_READY or HAL_TIM_STATE_RESET state,
+    thus registered(user) MspInit / DeInit callbacks can be used during the Init / DeInit.
+  In that case first register the MspInit/MspDeInit user callbacks
+      using @ref HAL_TIM_RegisterCallback() before calling DeInit or Init function.
+
+      When The compilation define USE_HAL_TIM_REGISTER_CALLBACKS is set to 0 or
+      not defined, the callback registration feature is not available and all callbacks
+      are set to the corresponding weak functions.

+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    The UART HAL driver can be used as follows:
+
+    (#) Declare a UART_HandleTypeDef handle structure (eg. UART_HandleTypeDef huart).
+    (#) Initialize the UART low level resources by implementing the HAL_UART_MspInit() API:
+        (##) Enable the USARTx interface clock.
+        (##) UART pins configuration:
+            (+++) Enable the clock for the UART GPIOs.
+            (+++) Configure these UART pins (TX as alternate function pull-up, RX as alternate function Input).
+        (##) NVIC configuration if you need to use interrupt process (HAL_UART_Transmit_IT()
+             and HAL_UART_Receive_IT() APIs):
+            (+++) Configure the USARTx interrupt priority.
+            (+++) Enable the NVIC USART IRQ handle.
+        (##) DMA Configuration if you need to use DMA process (HAL_UART_Transmit_DMA()
+             and HAL_UART_Receive_DMA() APIs):
+            (+++) Declare a DMA handle structure for the Tx/Rx channel.
+            (+++) Enable the DMAx interface clock.
+            (+++) Configure the declared DMA handle structure with the required
+                  Tx/Rx parameters.
+            (+++) Configure the DMA Tx/Rx channel.
+            (+++) Associate the initialized DMA handle to the UART DMA Tx/Rx handle.
+            (+++) Configure the priority and enable the NVIC for the transfer complete
+                  interrupt on the DMA Tx/Rx channel.
+            (+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle
+                  (used for last byte sending completion detection in DMA non circular mode)
+
+    (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware
+        flow control and Mode(Receiver/Transmitter) in the huart Init structure.
+
+    (#) For the UART asynchronous mode, initialize the UART registers by calling
+        the HAL_UART_Init() API.
+
+    (#) For the UART Half duplex mode, initialize the UART registers by calling
+        the HAL_HalfDuplex_Init() API.
+
+    (#) For the LIN mode, initialize the UART registers by calling the HAL_LIN_Init() API.
+
+    (#) For the Multi-Processor mode, initialize the UART registers by calling
+        the HAL_MultiProcessor_Init() API.
+
+     [..]
+       (@) The specific UART interrupts (Transmission complete interrupt,
+            RXNE interrupt and Error Interrupts) will be managed using the macros
+            __HAL_UART_ENABLE_IT() and __HAL_UART_DISABLE_IT() inside the transmit
+            and receive process.
+
+     [..]
+       (@) These APIs (HAL_UART_Init() and HAL_HalfDuplex_Init()) configure also the
+            low level Hardware GPIO, CLOCK, CORTEX...etc) by calling the customized
+            HAL_UART_MspInit() API.
+
+    ##### Callback registration #####
+    ==================================
+
+    [..]
+    The compilation define USE_HAL_UART_REGISTER_CALLBACKS when set to 1
+    allows the user to configure dynamically the driver callbacks.
+
+    [..]
+    Use Function @ref HAL_UART_RegisterCallback() to register a user callback.
+    Function @ref HAL_UART_RegisterCallback() allows to register following callbacks:
+    (+) TxHalfCpltCallback        : Tx Half Complete Callback.
+    (+) TxCpltCallback            : Tx Complete Callback.
+    (+) RxHalfCpltCallback        : Rx Half Complete Callback.
+    (+) RxCpltCallback            : Rx Complete Callback.
+    (+) ErrorCallback             : Error Callback.
+    (+) AbortCpltCallback         : Abort Complete Callback.
+    (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
+    (+) AbortReceiveCpltCallback  : Abort Receive Complete Callback.
+    (+) MspInitCallback           : UART MspInit.
+    (+) MspDeInitCallback         : UART MspDeInit.
+    This function takes as parameters the HAL peripheral handle, the Callback ID
+    and a pointer to the user callback function.
+
+    [..]
+    Use function @ref HAL_UART_UnRegisterCallback() to reset a callback to the default
+    weak (surcharged) function.
+    @ref HAL_UART_UnRegisterCallback() takes as parameters the HAL peripheral handle,
+    and the Callback ID.
+    This function allows to reset following callbacks:
+    (+) TxHalfCpltCallback        : Tx Half Complete Callback.
+    (+) TxCpltCallback            : Tx Complete Callback.
+    (+) RxHalfCpltCallback        : Rx Half Complete Callback.
+    (+) RxCpltCallback            : Rx Complete Callback.
+    (+) ErrorCallback             : Error Callback.
+    (+) AbortCpltCallback         : Abort Complete Callback.
+    (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
+    (+) AbortReceiveCpltCallback  : Abort Receive Complete Callback.
+    (+) MspInitCallback           : UART MspInit.
+    (+) MspDeInitCallback         : UART MspDeInit.
+
+    [..]
+    By default, after the @ref HAL_UART_Init() and when the state is HAL_UART_STATE_RESET
+    all callbacks are set to the corresponding weak (surcharged) functions:
+    examples @ref HAL_UART_TxCpltCallback(), @ref HAL_UART_RxHalfCpltCallback().
+    Exception done for MspInit and MspDeInit functions that are respectively
+    reset to the legacy weak (surcharged) functions in the @ref HAL_UART_Init()
+    and @ref HAL_UART_DeInit() only when these callbacks are null (not registered beforehand).
+    If not, MspInit or MspDeInit are not null, the @ref HAL_UART_Init() and @ref HAL_UART_DeInit()
+    keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
+
+    [..]
+    Callbacks can be registered/unregistered in HAL_UART_STATE_READY state only.
+    Exception done MspInit/MspDeInit that can be registered/unregistered
+    in HAL_UART_STATE_READY or HAL_UART_STATE_RESET state, thus registered (user)
+    MspInit/DeInit callbacks can be used during the Init/DeInit.
+    In that case first register the MspInit/MspDeInit user callbacks
+    using @ref HAL_UART_RegisterCallback() before calling @ref HAL_UART_DeInit()
+    or @ref HAL_UART_Init() function.
+
+    [..]
+    When The compilation define USE_HAL_UART_REGISTER_CALLBACKS is set to 0 or
+    not defined, the callback registration feature is not available
+    and weak (surcharged) callbacks are used.
+
+     [..]
+        Three operation modes are available within this driver :
+
+     *** Polling mode IO operation ***
+     =================================

+     ===================================

+       (+) Resume the DMA Transfer using HAL_UART_DMAResume()
+       (+) Stop the DMA Transfer using HAL_UART_DMAStop()
+
+     *** UART HAL driver macros list ***
+     =============================================
+     [..]
+       Below the list of most used macros in UART HAL driver.
+
+      (+) __HAL_UART_ENABLE: Enable the UART peripheral
+      (+) __HAL_UART_DISABLE: Disable the UART peripheral
+      (+) __HAL_UART_GET_FLAG : Check whether the specified UART flag is set or not
+      (+) __HAL_UART_CLEAR_FLAG : Clear the specified UART pending flag

+       (@) You can refer to the UART HAL driver header file for more useful macros
+
+  @endverbatim
+     [..]
+       (@) Additionnal remark: If the parity is enabled, then the MSB bit of the data written
+           in the data register is transmitted but is changed by the parity bit.
+           Depending on the frame length defined by the M bit (8-bits or 9-bits),
+           the possible UART frame formats are as listed in the following table:
+    +-------------------------------------------------------------+
+    |   M bit |  PCE bit  |            UART frame                 |

+ ===============================================================================
+    This subsection provides a set of functions allowing to manage the UART asynchronous
+    and Half duplex data transfers.
+
+    (#) There are two modes of transfer:
+       (+) Blocking mode: The communication is performed in polling mode.
+           The HAL status of all data processing is returned by the same function
+           after finishing transfer.
+       (+) Non-Blocking mode: The communication is performed using Interrupts
+           or DMA, these API's return the HAL status.
+           The end of the data processing will be indicated through the
+           dedicated UART IRQ when using Interrupt mode or the DMA IRQ when
+           using DMA mode.
+           The HAL_UART_TxCpltCallback(), HAL_UART_RxCpltCallback() user callbacks
+           will be executed respectively at the end of the transmit or receive process
+           The HAL_UART_ErrorCallback()user callback will be executed when a communication error is detected.
+
+    (#) Blocking mode API's are :
+        (+) HAL_UART_Transmit()
+        (+) HAL_UART_Receive()
+
+    (#) Non-Blocking mode API's with Interrupt are :
+        (+) HAL_UART_Transmit_IT()
+        (+) HAL_UART_Receive_IT()
+        (+) HAL_UART_IRQHandler()
+
+    (#) Non-Blocking mode API's with DMA are :
+        (+) HAL_UART_Transmit_DMA()
+        (+) HAL_UART_Receive_DMA()
+        (+) HAL_UART_DMAPause()
+        (+) HAL_UART_DMAResume()
+        (+) HAL_UART_DMAStop()
+
+    (#) A set of Transfer Complete Callbacks are provided in Non_Blocking mode:
+        (+) HAL_UART_TxHalfCpltCallback()
+        (+) HAL_UART_TxCpltCallback()
+        (+) HAL_UART_RxHalfCpltCallback()
+        (+) HAL_UART_RxCpltCallback()
+        (+) HAL_UART_ErrorCallback()
+
+    (#) Non-Blocking mode transfers could be aborted using Abort API's :
+        (+) HAL_UART_Abort()
+        (+) HAL_UART_AbortTransmit()
+        (+) HAL_UART_AbortReceive()
+        (+) HAL_UART_Abort_IT()
+        (+) HAL_UART_AbortTransmit_IT()
+        (+) HAL_UART_AbortReceive_IT()
+
+    (#) For Abort services based on interrupts (HAL_UART_Abortxxx_IT), a set of Abort Complete Callbacks are provided:
+        (+) HAL_UART_AbortCpltCallback()
+        (+) HAL_UART_AbortTransmitCpltCallback()
+        (+) HAL_UART_AbortReceiveCpltCallback()
+
+    (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
+        Errors are handled as follows :
+       (+) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
+           to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
+           Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
+           and HAL_UART_ErrorCallback() user callback is executed. Transfer is kept ongoing on UART side.
+           If user wants to abort it, Abort services should be called by user.
+       (+) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
+           This concerns Overrun Error In Interrupt mode reception and all errors in DMA mode.
+           Error code is set to allow user to identify error type, and HAL_UART_ErrorCallback() user callback is executed.
+
+    -@- In the Half duplex communication, it is forbidden to run the transmit
+        and receive process in parallel, the UART state HAL_UART_STATE_BUSY_TX_RX can't be useful.

+  ==============================================================================
+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    The USART HAL driver can be used as follows:
+
+    (#) Declare a USART_HandleTypeDef handle structure (eg. USART_HandleTypeDef husart).
+    (#) Initialize the USART low level resources by implementing the HAL_USART_MspInit() API:
+        (##) Enable the USARTx interface clock.
+        (##) USART pins configuration:
+             (+++) Enable the clock for the USART GPIOs.
+             (+++) Configure the USART pins as alternate function pull-up.
+        (##) NVIC configuration if you need to use interrupt process (HAL_USART_Transmit_IT(),
+             HAL_USART_Receive_IT() and HAL_USART_TransmitReceive_IT() APIs):
+             (+++) Configure the USARTx interrupt priority.
+             (+++) Enable the NVIC USART IRQ handle.
+        (##) DMA Configuration if you need to use DMA process (HAL_USART_Transmit_DMA()
+             HAL_USART_Receive_DMA() and HAL_USART_TransmitReceive_DMA() APIs):
+             (+++) Declare a DMA handle structure for the Tx/Rx channel.
+             (+++) Enable the DMAx interface clock.
+             (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
+             (+++) Configure the DMA Tx/Rx channel.
+             (+++) Associate the initialized DMA handle to the USART DMA Tx/Rx handle.
+             (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
+             (+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle
+                   (used for last byte sending completion detection in DMA non circular mode)
+
+    (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware
+        flow control and Mode(Receiver/Transmitter) in the husart Init structure.
+
+    (#) Initialize the USART registers by calling the HAL_USART_Init() API:
+        (++) These APIs configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+             by calling the customized HAL_USART_MspInit(&husart) API.
+
+        -@@- The specific USART interrupts (Transmission complete interrupt,
+             RXNE interrupt and Error Interrupts) will be managed using the macros
+             __HAL_USART_ENABLE_IT() and __HAL_USART_DISABLE_IT() inside the transmit and receive process.
+
+    (#) Three operation modes are available within this driver :
+
+     *** Polling mode IO operation ***
+     =================================
+     [..]
+       (+) Send an amount of data in blocking mode using HAL_USART_Transmit()
+       (+) Receive an amount of data in blocking mode using HAL_USART_Receive()
+
+     *** Interrupt mode IO operation ***
+     ===================================
+     [..]
+       (+) Send an amount of data in non blocking mode using HAL_USART_Transmit_IT()
+       (+) At transmission end of transfer HAL_USART_TxHalfCpltCallback is executed and user can
+            add his own code by customization of function pointer HAL_USART_TxCpltCallback

+       (+) At transmission end of transfer HAL_USART_TxCpltCallback is executed and user can

+       (+) Resume the DMA Transfer using HAL_USART_DMAResume()
+       (+) Stop the DMA Transfer using HAL_USART_DMAStop()
+
+     *** USART HAL driver macros list ***
+     =============================================
+     [..]
+       Below the list of most used macros in USART HAL driver.
+
+       (+) __HAL_USART_ENABLE: Enable the USART peripheral
+       (+) __HAL_USART_DISABLE: Disable the USART peripheral
+       (+) __HAL_USART_GET_FLAG : Check whether the specified USART flag is set or not
+       (+) __HAL_USART_CLEAR_FLAG : Clear the specified USART pending flag
+       (+) __HAL_USART_ENABLE_IT: Enable the specified USART interrupt
+       (+) __HAL_USART_DISABLE_IT: Disable the specified USART interrupt
+
+     [..]
+       (@) You can refer to the USART HAL driver header file for more useful macros
+
+    ##### Callback registration #####
+    ==================================
+
+    [..]
+    The compilation define USE_HAL_USART_REGISTER_CALLBACKS when set to 1
+    allows the user to configure dynamically the driver callbacks.
+
+    [..]
+    Use Function @ref HAL_USART_RegisterCallback() to register a user callback.
+    Function @ref HAL_USART_RegisterCallback() allows to register following callbacks:
+    (+) TxHalfCpltCallback        : Tx Half Complete Callback.
+    (+) TxCpltCallback            : Tx Complete Callback.
+    (+) RxHalfCpltCallback        : Rx Half Complete Callback.
+    (+) RxCpltCallback            : Rx Complete Callback.
+    (+) TxRxCpltCallback          : Tx Rx Complete Callback.
+    (+) ErrorCallback             : Error Callback.
+    (+) AbortCpltCallback         : Abort Complete Callback.
+    (+) MspInitCallback           : USART MspInit.
+    (+) MspDeInitCallback         : USART MspDeInit.
+    This function takes as parameters the HAL peripheral handle, the Callback ID
+    and a pointer to the user callback function.
+
+    [..]
+    Use function @ref HAL_USART_UnRegisterCallback() to reset a callback to the default
+    weak (surcharged) function.
+    @ref HAL_USART_UnRegisterCallback() takes as parameters the HAL peripheral handle,
+    and the Callback ID.
+    This function allows to reset following callbacks:
+    (+) TxHalfCpltCallback        : Tx Half Complete Callback.
+    (+) TxCpltCallback            : Tx Complete Callback.
+    (+) RxHalfCpltCallback        : Rx Half Complete Callback.
+    (+) RxCpltCallback            : Rx Complete Callback.
+    (+) TxRxCpltCallback          : Tx Rx Complete Callback.
+    (+) ErrorCallback             : Error Callback.
+    (+) AbortCpltCallback         : Abort Complete Callback.
+    (+) MspInitCallback           : USART MspInit.
+    (+) MspDeInitCallback         : USART MspDeInit.
+
+    [..]
+    By default, after the @ref HAL_USART_Init() and when the state is HAL_USART_STATE_RESET
+    all callbacks are set to the corresponding weak (surcharged) functions:
+    examples @ref HAL_USART_TxCpltCallback(), @ref HAL_USART_RxHalfCpltCallback().
+    Exception done for MspInit and MspDeInit functions that are respectively
+    reset to the legacy weak (surcharged) functions in the @ref HAL_USART_Init()
+    and @ref HAL_USART_DeInit() only when these callbacks are null (not registered beforehand).
+    If not, MspInit or MspDeInit are not null, the @ref HAL_USART_Init() and @ref HAL_USART_DeInit()
+    keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
+
+    [..]
+    Callbacks can be registered/unregistered in HAL_USART_STATE_READY state only.
+    Exception done MspInit/MspDeInit that can be registered/unregistered
+    in HAL_USART_STATE_READY or HAL_USART_STATE_RESET state, thus registered (user)
+    MspInit/DeInit callbacks can be used during the Init/DeInit.
+    In that case first register the MspInit/MspDeInit user callbacks
+    using @ref HAL_USART_RegisterCallback() before calling @ref HAL_USART_DeInit()
+    or @ref HAL_USART_Init() function.
+
+    [..]
+    When The compilation define USE_HAL_USART_REGISTER_CALLBACKS is set to 0 or
+    not defined, the callback registration feature is not available
+    and weak (surcharged) callbacks are used.
+
+  @endverbatim
+     [..]
+       (@) Additionnal remark: If the parity is enabled, then the MSB bit of the data written
+           in the data register is transmitted but is changed by the parity bit.
+           Depending on the frame length defined by the M bit (8-bits or 9-bits),
+           the possible USART frame formats are as listed in the following table:
+    +-------------------------------------------------------------+
+    |   M bit |  PCE bit  |            USART frame                 |
+    |---------------------|---------------------------------------|
+    |    0    |    0      |    | SB | 8 bit data | STB |          |
+    |---------|-----------|---------------------------------------|
+    |    0    |    1      |    | SB | 7 bit data | PB | STB |     |
+    |---------|-----------|---------------------------------------|
+    |    1    |    0      |    | SB | 9 bit data | STB |          |
+    |---------|-----------|---------------------------------------|
+    |    1    |    1      |    | SB | 8 bit data | PB | STB |     |

+  [..]
+  This subsection provides a set of functions allowing to initialize the USART
+  in asynchronous and in synchronous modes.
+  (+) For the asynchronous mode only these parameters can be configured:
+      (++) Baud Rate
+      (++) Word Length
+      (++) Stop Bit
+      (++) Parity: If the parity is enabled, then the MSB bit of the data written
+           in the data register is transmitted but is changed by the parity bit.
+           Depending on the frame length defined by the M bit (8-bits or 9-bits),
+           please refer to Reference manual for possible USART frame formats.
+      (++) USART polarity
+      (++) USART phase
+      (++) USART LastBit
+      (++) Receiver/transmitter modes
+
+  [..]
+    The HAL_USART_Init() function follows the USART  synchronous configuration
+    procedures (details for the procedures are available in reference manual (RM0038)).

+

+    The USART supports master mode only: it cannot receive or send data related to an input
+    clock (SCLK is always an output).
+
+    (#) There are two modes of transfer:
+        (++) Blocking mode: The communication is performed in polling mode.
+             The HAL status of all data processing is returned by the same function
+             after finishing transfer.
+        (++) No-Blocking mode: The communication is performed using Interrupts
+             or DMA, These API's return the HAL status.
+             The end of the data processing will be indicated through the
+             dedicated USART IRQ when using Interrupt mode or the DMA IRQ when
+             using DMA mode.
+             The HAL_USART_TxCpltCallback(), HAL_USART_RxCpltCallback() and HAL_USART_TxRxCpltCallback()
+              user callbacks
+             will be executed respectively at the end of the transmit or Receive process
+             The HAL_USART_ErrorCallback() user callback will be executed when a communication
+             error is detected
+
+    (#) Blocking mode APIs are :
+        (++) HAL_USART_Transmit() in simplex mode
+        (++) HAL_USART_Receive() in full duplex receive only
+        (++) HAL_USART_TransmitReceive() in full duplex mode
+

+        (++) HAL_USART_Transmit_IT()in simplex mode
+        (++) HAL_USART_Receive_IT() in full duplex receive only
+        (++) HAL_USART_TransmitReceive_IT() in full duplex mode
+        (++) HAL_USART_IRQHandler()
+
+    (#) Non Blocking mode functions with DMA are :

+        (++) HAL_USART_Receive_DMA() in full duplex receive only
+        (++) HAL_USART_TransmitReceive_DMA() in full duplex mode
+        (++) HAL_USART_DMAPause()
+        (++) HAL_USART_DMAResume()
+        (++) HAL_USART_DMAStop()
+
+    (#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
+        (++) HAL_USART_TxHalfCpltCallback()
+        (++) HAL_USART_TxCpltCallback()
+        (++) HAL_USART_RxHalfCpltCallback()
+        (++) HAL_USART_RxCpltCallback()
+        (++) HAL_USART_ErrorCallback()
+        (++) HAL_USART_TxRxCpltCallback()
+
+    (#) Non-Blocking mode transfers could be aborted using Abort API's :
+        (++) HAL_USART_Abort()
+        (++) HAL_USART_Abort_IT()
+
+    (#) For Abort services based on interrupts (HAL_USART_Abort_IT), a Abort Complete Callbacks is provided:
+        (++) HAL_USART_AbortCpltCallback()
+
+    (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
+        Errors are handled as follows :
+        (++) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
+             to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
+             Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
+             and HAL_USART_ErrorCallback() user callback is executed. Transfer is kept ongoing on USART side.
+             If user wants to abort it, Abort services should be called by user.
+        (++) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
+             This concerns Overrun Error In Interrupt mode reception and all errors in DMA mode.
+             Error code is set to allow user to identify error type, and HAL_USART_ErrorCallback() user callback is executed.

+  * @brief   WWDG HAL module driver.
+  *          This file provides firmware functions to manage the following
+  *          functionalities of the Window Watchdog (WWDG) peripheral:
+  *           + Initialization and Configuration functions
+  *           + IO operation functions
+  @verbatim
+  ==============================================================================
+                      ##### WWDG Specific features #####
+  ==============================================================================
+  [..]
+    Once enabled the WWDG generates a system reset on expiry of a programmed
+    time period, unless the program refreshes the counter (T[6;0] downcounter)
+    before reaching 0x3F value (i.e. a reset is generated when the counter
+    value rolls down from 0x40 to 0x3F).
+
+    (+) An MCU reset is also generated if the counter value is refreshed
+        before the counter has reached the refresh window value. This
+        implies that the counter must be refreshed in a limited window.
+    (+) Once enabled the WWDG cannot be disabled except by a system reset.
+    (+) WWDGRST flag in RCC CSR register can be used to inform when a WWDG
+        reset occurs.
+    (+) The WWDG counter input clock is derived from the APB clock divided
+        by a programmable prescaler.
+    (+) WWDG clock (Hz) = PCLK1 / (4096 * Prescaler)
+    (+) WWDG timeout (mS) = 1000 * (T[5;0] + 1) / WWDG clock (Hz)
+        where T[5;0] are the lowest 6 bits of Counter.
+    (+) WWDG Counter refresh is allowed between the following limits :
+        (++) min time (mS) = 1000 * (Counter - Window) / WWDG clock
+        (++) max time (mS) = 1000 * (Counter - 0x40) / WWDG clock
+    (+) Typical values:
+        (++) Counter min (T[5;0] = 0x00) @32MHz (PCLK1) with zero prescaler:
+             max timeout before reset: approximately 128 microseconds
+        (++) Counter max (T[5;0] = 0x3F) @32MHz (PCLK1) with prescaler dividing by 128:
+             max timeout before reset: approximately 65.54 milliseconds
+
+  ==============================================================================
+                     ##### How to use this driver #####
+  ==============================================================================
+
+    *** Common driver usage ***
+    ===========================
+
+  [..]
+    (+) Enable WWDG APB1 clock using __HAL_RCC_WWDG_CLK_ENABLE().
+    (+) Set the WWDG prescaler, refresh window and counter value
+        using HAL_WWDG_Init() function.
+    (+) Start the WWDG using HAL_WWDG_Start() function.
+        When the WWDG is enabled the counter value should be configured to
+        a value greater than 0x40 to prevent generating an immediate reset.
+    (+) Optionally you can enable the Early Wakeup Interrupt (EWI) which is
+        generated when the counter reaches 0x40, and then start the WWDG using
+        HAL_WWDG_Start_IT(). At EWI HAL_WWDG_WakeupCallback is executed and user can
+        add his own code by customization of callback HAL_WWDG_WakeupCallback.
+        Once enabled, EWI interrupt cannot be disabled except by a system reset.
+    (+) Then the application program must refresh the WWDG counter at regular
+        intervals during normal operation to prevent an MCU reset, using
+        HAL_WWDG_Refresh() function. This operation must occur only when
+        the counter is lower than the refresh window value already programmed.
+
+    *** Callback registration ***
+    =============================
+
+  [..]
+    The compilation define  USE_HAL_WWDG_REGISTER_CALLBACKS when set to 1 allows
+    the user to configure dynamically the driver callbacks. Use Functions
+    @ref HAL_WWDG_RegisterCallback() to register a user callback.
+
+    (+) Function @ref HAL_WWDG_RegisterCallback() allows to register following
+        callbacks:
+        (++) EwiCallback : callback for Early WakeUp Interrupt.
+        (++) MspInitCallback : WWDG MspInit.
+    This function takes as parameters the HAL peripheral handle, the Callback ID
+    and a pointer to the user callback function.
+
+    (+) Use function @ref HAL_WWDG_UnRegisterCallback() to reset a callback to
+    the default weak (surcharged) function. @ref HAL_WWDG_UnRegisterCallback()
+    takes as parameters the HAL peripheral handle and the Callback ID.
+    This function allows to reset following callbacks:
+        (++) EwiCallback : callback for  Early WakeUp Interrupt.
+        (++) MspInitCallback : WWDG MspInit.
+
+    [..]
+    When calling @ref HAL_WWDG_Init function, callbacks are reset to the
+    corresponding legacy weak (surcharged) functions: 
+    @ref HAL_WWDG_EarlyWakeupCallback() and HAL_WWDG_MspInit() only if they have
+    not been registered before.
+
+    [..]
+    When compilation define USE_HAL_WWDG_REGISTER_CALLBACKS is set to 0 or
+    not defined, the callback registering feature is not available 
+    and weak (surcharged) callbacks are used.
+
+    *** WWDG HAL driver macros list ***
+    ===================================
+    [..]
+      Below the list of most used macros in WWDG HAL driver.
+      (+) __HAL_WWDG_ENABLE: Enable the WWDG peripheral
+      (+) __HAL_WWDG_GET_FLAG: Get the selected WWDG's flag status
+      (+) __HAL_WWDG_CLEAR_FLAG: Clear the WWDG's pending flags
+      (+) __HAL_WWDG_ENABLE_IT: Enable the WWDG early wakeup interrupt

+  =============================================================================
+                        ##### FSMC peripheral features #####
+  =============================================================================
+    [..] The Flexible static memory controller (FSMC) includes following memory controllers:
+         (+) The NOR/PSRAM memory controller
+
+    [..] The FSMC functional block makes the interface with synchronous and asynchronous static
+         memories. Its main purposes are:
+         (+) to translate AHB transactions into the appropriate external device protocol.
+         (+) to meet the access time requirements of the external memory devices.
+
+    [..] All external memories share the addresses, data and control signals with the controller.
+         Each external device is accessed by means of a unique Chip Select. The FSMC performs
+         only one access at a time to an external device.
+         The main features of the FSMC controller are the following:
+          (+) Interface with static-memory mapped devices including:
+             (++) Static random access memory (SRAM).
+             (++) NOR Flash memory.
+             (++) PSRAM (4 memory banks).
+          (+) Independent Chip Select control for each memory bank
+          (+) Independent configuration for each memory bank

+  ==============================================================================
+                       ##### SDMMC peripheral features #####
+  ==============================================================================        
+    [..] The SD/SDMMC MMC card host interface (SDMMC) provides an interface between the AHB
+         peripheral bus and MultiMedia cards (MMCs), SD memory cards, SDMMC cards and CE-ATA
+         devices.
+    
+    [..] The SDMMC features include the following:
+         (+) Full compliance with MultiMedia Card System Specification Version 4.2. Card support
+             for three different databus modes: 1-bit (default), 4-bit and 8-bit
+         (+) Full compatibility with previous versions of MultiMedia Cards (forward compatibility)
+         (+) Full compliance with SD Memory Card Specifications Version 2.0
+         (+) Full compliance with SD I/O Card Specification Version 2.0: card support for two
+             different data bus modes: 1-bit (default) and 4-bit
+         (+) Full support of the CE-ATA features (full compliance with CE-ATA digital protocol
+             Rev1.1)
+         (+) Data transfer up to 48 MHz for the 8 bit mode
+         (+) Data and command output enable signals to control external bidirectional drivers
+   
+                           ##### How to use this driver #####
+  ==============================================================================
+    [..]
+      This driver is a considered as a driver of service for external devices drivers 
+      that interfaces with the SDMMC peripheral.
+      According to the device used (SD card/ MMC card / SDMMC card ...), a set of APIs 
+      is used in the device's driver to perform SDMMC operations and functionalities.
+   
+      This driver is almost transparent for the final user, it is only used to implement other
+      functionalities of the external device.
+   
+    [..]
+      (+) The SDMMC clock (SDMMCCLK = 48 MHz) is coming from a specific output (MSI, PLLUSB1CLK,
+          PLLUSB2CLK). Before start working with SDMMC peripheral make sure that the
+          PLL is well configured.
+          The SDMMC peripheral uses two clock signals:
+          (++) SDMMC adapter clock (SDMMCCLK = 48 MHz)
+          (++) APB2 bus clock (PCLK2)
+       
+          -@@- PCLK2 and SDMMC_CK clock frequencies must respect the following condition:
+               Frequency(PCLK2) >= (3 / 8 x Frequency(SDMMC_CK))
+  
+      (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDMMC
+          peripheral.
+
+      (+) Enable the Power ON State using the SDIO_PowerState_ON() 
+          function and disable it using the function SDIO_PowerState_OFF().
+                
+      (+) Enable/Disable the clock using the __SDIO_ENABLE()/__SDIO_DISABLE() macros.
+  
+      (+) Enable/Disable the peripheral interrupts using the macros __SDIO_ENABLE_IT() 
+          and __SDIO_DISABLE_IT() if you need to use interrupt mode. 
+  
+      (+) When using the DMA mode 
+          (++) Configure the DMA in the MSP layer of the external device
+          (++) Active the needed channel Request 
+          (++) Enable the DMA using __SDIO_DMA_ENABLE() macro or Disable it using the macro
+               __SDIO_DMA_DISABLE().
+  
+      (+) To control the CPSM (Command Path State Machine) and send 
+          commands to the card use the SDIO_SendCommand(), 
+          SDIO_GetCommandResponse() and SDIO_GetResponse() functions. First, user has
+          to fill the command structure (pointer to SDIO_CmdInitTypeDef) according 
+          to the selected command to be sent.
+          The parameters that should be filled are:
+           (++) Command Argument
+           (++) Command Index
+           (++) Command Response type
+           (++) Command Wait
+           (++) CPSM Status (Enable or Disable).
+  
+          -@@- To check if the command is well received, read the SDIO_CMDRESP
+              register using the SDIO_GetCommandResponse().
+              The SDMMC responses registers (SDIO_RESP1 to SDIO_RESP2), use the
+              SDIO_GetResponse() function.
+  
+      (+) To control the DPSM (Data Path State Machine) and send/receive 
+           data to/from the card use the SDIO_DataConfig(), SDIO_GetDataCounter(), 
+          SDIO_ReadFIFO(), SDIO_WriteFIFO() and SDIO_GetFIFOCount() functions.
+

+      (#) First, user has to fill the data structure (pointer to

+     (#) The commands used for Read/Write/Erase operations are managed in 
+         separate functions. 
+         Each function allows to send the needed command with the related argument,
+         then check the response.
+         By the same approach, you could implement a command and check the response.
