+# 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 [stm32f0xx_hal_driver](https://github.com/STMicroelectronics/stm32f0xx_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

+ * New ADC conversion starts only when the previous

+ * This mode allows to automatically adapt the ADC conversions
+ * triggers to the speed of the software that reads the data.
+ * Moreover, this avoids risk of overrun for low frequency
+ * applications.
+ * How to use this low power mode:
+ * - Do not use with interruption or DMA since these modes
+ * have to clear immediately the EOC flag to free the
+ * IRQ vector sequencer.
+ * - Do use with polling: 1. Start conversion,
+ * 2. Later on, when conversion data is needed: poll for end of
+ * conversion to ensure that conversion is completed and
+ * retrieve ADC conversion data. This will trig another
+ * ADC conversion start.
+ * - ADC low power mode "auto power-off" (feature available on
+ * this device if parameter LL_ADC_LP_MODE_AUTOOFF is available):
+ * the ADC automatically powers-off after a conversion and
+ * automatically wakes up when a new conversion is triggered
+ * (with startup time between trigger and start of sampling).
+ * This feature can be combined with low power mode "auto wait".
+ * @note With ADC low power mode "auto wait", the ADC conversion data read
+ * is corresponding to previous ADC conversion start, independently
+ * of delay during which ADC was idle.
+ * Therefore, the ADC conversion data may be outdated: does not

+ ##### 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.

-# stm32f0xx_hal_driver
-Provides the STM32Cube MCU Component "hal_driver" of the STM32F0 series.
+# STM32CubeF0 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 **stm32f0xx_hal_driver** MCU component repo is one element of the STM32CubeF0 MCU embedded software package, providing the **HAL-LL Drivers** part.

+ ******************************************************************************
+ * @file stm32f0xx_hal_can.c
+ * @author MCD Application Team
+ * @brief This file provides firmware functions to manage the following
+ * functionalities of the Controller Area Network (CAN) peripheral:
+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral Control functions
+ * + Peripheral State and Error functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### User NOTE #####
+ ==============================================================================
+ [..]
+ (#) This HAL CAN driver is deprecated, it contains some CAN Tx/Rx FIFO management limitations.
+ Another HAL CAN driver version has been designed with new API's, to fix these limitations.
+
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#) Enable the CAN controller interface clock using __HAL_RCC_CAN1_CLK_ENABLE();
+
+ (#) CAN pins configuration
+ (++) Enable the clock for the CAN GPIOs using the following function:
+ __HAL_RCC_GPIOx_CLK_ENABLE();
+ (++) Connect and configure the involved CAN pins to AF9 using the
+ following function HAL_GPIO_Init();
+
+ (#) Initialise and configure the CAN using HAL_CAN_Init() function.
+
+ (#) Transmit the desired CAN frame using HAL_CAN_Transmit() function.
+
+ (#) Or transmit the desired CAN frame using HAL_CAN_Transmit_IT() function.
+
+ (#) Receive a CAN frame using HAL_CAN_Receive() function.
+
+ (#) Or receive a CAN frame using HAL_CAN_Receive_IT() function.
+
+ *** Polling mode IO operation ***
+ =================================
+ [..]
+ (+) Start the CAN peripheral transmission and wait the end of this operation
+ using HAL_CAN_Transmit(), at this stage user can specify the value of timeout
+ according to his end application
+ (+) Start the CAN peripheral reception and wait the end of this operation
+ using HAL_CAN_Receive(), at this stage user can specify the value of timeout
+ according to his end application
+
+ *** Interrupt mode IO operation ***
+ ===================================
+ [..]
+ (+) Start the CAN peripheral transmission using HAL_CAN_Transmit_IT()
+ (+) Start the CAN peripheral reception using HAL_CAN_Receive_IT()
+ (+) Use HAL_CAN_IRQHandler() called under the used CAN Interrupt subroutine
+ (+) At CAN end of transmission HAL_CAN_TxCpltCallback() function is executed and user can
+ add his own code by customization of function pointer HAL_CAN_TxCpltCallback
+ (+) In case of CAN Error, HAL_CAN_ErrorCallback() function is executed and user can
+ add his own code by customization of function pointer HAL_CAN_ErrorCallback
+
+ *** CAN HAL driver macros list ***
+ =============================================
+ [..]
+ Below the list of most used macros in CAN HAL driver.
+
+ (+) __HAL_CAN_ENABLE_IT: Enable the specified CAN interrupts
+ (+) __HAL_CAN_DISABLE_IT: Disable the specified CAN interrupts
+ (+) __HAL_CAN_GET_IT_SOURCE: Check if the specified CAN interrupt source is enabled or disabled
+ (+) __HAL_CAN_CLEAR_FLAG: Clear the CAN's pending flags
+ (+) __HAL_CAN_GET_FLAG: Get the selected CAN's flag status
+
+ [..]
+ (@) You can refer to the CAN Legacy HAL driver header file for more useful macros

+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+
+ *** Configuration of top level parameters related to ADC ***
+ ============================================================
+ [..]
+
+ (#) Enable the ADC interface
+ (++) As prerequisite, ADC clock must be configured at RCC top level.
+ Caution: On STM32F0, ADC clock frequency max is 14MHz (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, also possibly conversion clock).
+
+ (+++) ADC clock (conversions clock).
+ Two possible clock sources: synchronous clock derived from APB clock
+ or asynchronous clock derived from ADC dedicated HSI RC oscillator
+ 14MHz.
+ If asynchronous clock is selected, parameter "HSI14State" must be set either:
+ - to "...HSI14State = RCC_HSI14_ADC_CONTROL" to let the ADC control
+ the HSI14 oscillator enable/disable (if not used to supply the main
+ system clock): feature used if ADC mode LowPowerAutoPowerOff is
+ enabled.
+ - to "...HSI14State = RCC_HSI14_ON" to maintain the HSI14 oscillator
+ always enabled: can be used to supply the main system clock.
+
+ (+++) Example:
+ Into HAL_ADC_MspInit() (recommended code location) or with
+ other device clock parameters configuration:
+ (+++) __HAL_RCC_ADC1_CLK_ENABLE(); (mandatory)
+
+ HI14 enable or let under control of ADC: (optional: if asynchronous clock selected)
+ (+++) RCC_OscInitTypeDef RCC_OscInitStructure;
+ (+++) RCC_OscInitStructure.OscillatorType = RCC_OSCILLATORTYPE_HSI14;
+ (+++) RCC_OscInitStructure.HSI14CalibrationValue = RCC_HSI14CALIBRATION_DEFAULT;
+ (+++) RCC_OscInitStructure.HSI14State = RCC_HSI14_ADC_CONTROL;
+ (+++) RCC_OscInitStructure.PLL... (optional if used for system clock)
+ (+++) HAL_RCC_OscConfig(&RCC_OscInitStructure);
+
+ (++) ADC clock source and clock prescaler are configured at ADC level with
+ parameter "ClockPrescaler" using function HAL_ADC_Init().
+
+ (#) ADC pins configuration
+ (++) Enable the clock for the ADC GPIOs
+ using macro __HAL_RCC_GPIOx_CLK_ENABLE()
+ (++) Configure these ADC pins in analog mode
+ using function HAL_GPIO_Init()
+
+ (#) Optionally, in case of usage of ADC with interruptions:
+ (++) Configure the NVIC for ADC
+ using function HAL_NVIC_EnableIRQ(ADCx_IRQn)
+ (++) Insert the ADC interruption handler function HAL_ADC_IRQHandler()
+ into the function of corresponding ADC interruption vector
+ ADCx_IRQHandler().
+
+ (#) Optionally, in case of usage of DMA:
+ (++) Configure the DMA (DMA channel, mode normal or circular, ...)
+ using function HAL_DMA_Init().
+ (++) Configure the NVIC for DMA
+ using function HAL_NVIC_EnableIRQ(DMAx_Channelx_IRQn)
+ (++) Insert the ADC interruption handler function HAL_ADC_IRQHandler()
+ into the function of corresponding DMA interruption vector
+ DMAx_Channelx_IRQHandler().
+
+ *** Configuration of ADC, group regular, channels parameters ***
+ ================================================================
+ [..]
+
+ (#) Configure the ADC parameters (resolution, data alignment, ...)
+ and regular group parameters (conversion trigger, sequencer, ...)
+ using function HAL_ADC_Init().
+
+ (#) Configure the channels for regular group parameters (channel number,
+ channel rank into sequencer, ..., into regular group)
+ using function HAL_ADC_ConfigChannel().
+
+ (#) Optionally, configure the analog watchdog parameters (channels
+ monitored, thresholds, ...)
+ using function HAL_ADC_AnalogWDGConfig().
+
+ *** Execution of ADC conversions ***
+ ====================================
+ [..]
+
+ (#) Optionally, perform an automatic ADC calibration to improve the
+ conversion accuracy
+ using function HAL_ADCEx_Calibration_Start().
+
+ (#) ADC driver can be used among three modes: polling, interruption,
+ transfer by DMA.
+
+ (++) ADC conversion by polling:
+ (+++) Activate the ADC peripheral and start conversions
+ using function HAL_ADC_Start()
+ (+++) Wait for ADC conversion completion
+ using function HAL_ADC_PollForConversion()
+ (+++) Retrieve conversion results
+ using function HAL_ADC_GetValue()
+ (+++) Stop conversion and disable the ADC peripheral
+ using function HAL_ADC_Stop()
+
+ (++) ADC conversion by interruption:
+ (+++) Activate the ADC peripheral and start conversions
+ using function HAL_ADC_Start_IT()
+ (+++) Wait for ADC conversion completion by call of function
+ HAL_ADC_ConvCpltCallback()
+ (this function must be implemented in user program)
+ (+++) Retrieve conversion results
+ using function HAL_ADC_GetValue()
+ (+++) Stop conversion and disable the ADC peripheral
+ using function HAL_ADC_Stop_IT()
+
+ (++) ADC conversion with transfer by DMA:
+ (+++) Activate the ADC peripheral and start conversions
+ using function HAL_ADC_Start_DMA()
+ (+++) Wait for ADC conversion completion by call of function
+ HAL_ADC_ConvCpltCallback() or HAL_ADC_ConvHalfCpltCallback()
+ (these functions must be implemented in user program)
+ (+++) Conversion results are automatically transferred by DMA into
+ destination variable address.
+ (+++) Stop conversion and disable the ADC peripheral
+ using function HAL_ADC_Stop_DMA()
+
+ [..]
+
+ (@) Callback functions must be implemented in user program:
+ (+@) HAL_ADC_ErrorCallback()
+ (+@) HAL_ADC_LevelOutOfWindowCallback() (callback of analog watchdog)
+ (+@) HAL_ADC_ConvCpltCallback()
+ (+@) HAL_ADC_ConvHalfCpltCallback
+
+ *** Deinitialization of ADC ***
+ ============================================================
+ [..]
+
+ (#) Disable the ADC interface
+ (++) ADC clock can be hard reset and disabled at RCC top level.
+ (++) Hard reset of ADC peripherals
+ using macro __ADCx_FORCE_RESET(), __ADCx_RELEASE_RESET().
+ (++) ADC clock disable
+ using the equivalent macro/functions as configuration step.
+ (+++) Example:
+ Into HAL_ADC_MspDeInit() (recommended code location) or with
+ other device clock parameters configuration:
+ (+++) RCC_OscInitStructure.OscillatorType = RCC_OSCILLATORTYPE_HSI14;
+ (+++) RCC_OscInitStructure.HSI14State = RCC_HSI14_OFF; (if not used for system clock)
+ (+++) HAL_RCC_OscConfig(&RCC_OscInitStructure);
+
+ (#) ADC pins configuration
+ (++) Disable the clock for the ADC GPIOs
+ using macro __HAL_RCC_GPIOx_CLK_DISABLE()
+
+ (#) Optionally, in case of usage of ADC with interruptions:
+ (++) Disable the NVIC for ADC
+ using function HAL_NVIC_EnableIRQ(ADCx_IRQn)
+
+ (#) Optionally, in case of usage of DMA:
+ (++) Deinitialize the DMA
+ using function HAL_DMA_Init().

+ using function HAL_NVIC_EnableIRQ(DMAx_Channelx_IRQn)

+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#) Initialize the CAN low level resources by implementing the
+ HAL_CAN_MspInit():
+ (++) Enable the CAN interface clock using __HAL_RCC_CANx_CLK_ENABLE()
+ (++) Configure CAN pins
+ (+++) Enable the clock for the CAN GPIOs
+ (+++) Configure CAN pins as alternate function open-drain
+ (++) In case of using interrupts (e.g. HAL_CAN_ActivateNotification())
+ (+++) Configure the CAN interrupt priority using
+ HAL_NVIC_SetPriority()
+ (+++) Enable the CAN IRQ handler using HAL_NVIC_EnableIRQ()
+ (+++) In CAN IRQ handler, call HAL_CAN_IRQHandler()
+
+ (#) Initialize the CAN peripheral using HAL_CAN_Init() function. This
+ function resorts to HAL_CAN_MspInit() for low-level initialization.
+
+ (#) Configure the reception filters using the following configuration
+ functions:
+ (++) HAL_CAN_ConfigFilter()
+
+ (#) Start the CAN module using HAL_CAN_Start() function. At this level
+ the node is active on the bus: it receive messages, and can send
+ messages.
+
+ (#) To manage messages transmission, the following Tx control functions
+ can be used:
+ (++) HAL_CAN_AddTxMessage() to request transmission of a new
+ message.
+ (++) HAL_CAN_AbortTxRequest() to abort transmission of a pending
+ message.
+ (++) HAL_CAN_GetTxMailboxesFreeLevel() to get the number of free Tx
+ mailboxes.
+ (++) HAL_CAN_IsTxMessagePending() to check if a message is pending
+ in a Tx mailbox.
+ (++) HAL_CAN_GetTxTimestamp() to get the timestamp of Tx message
+ sent, if time triggered communication mode is enabled.
+
+ (#) When a message is received into the CAN Rx FIFOs, it can be retrieved
+ using the HAL_CAN_GetRxMessage() function. The function
+ HAL_CAN_GetRxFifoFillLevel() allows to know how many Rx message are
+ stored in the Rx Fifo.
+
+ (#) Calling the HAL_CAN_Stop() function stops the CAN module.
+
+ (#) The deinitialization is achieved with HAL_CAN_DeInit() function.
+
+
+ *** Polling mode operation ***
+ ==============================
+ [..]
+ (#) Reception:
+ (++) Monitor reception of message using HAL_CAN_GetRxFifoFillLevel()
+ until at least one message is received.
+ (++) Then get the message using HAL_CAN_GetRxMessage().
+
+ (#) Transmission:
+ (++) Monitor the Tx mailboxes availability until at least one Tx
+ mailbox is free, using HAL_CAN_GetTxMailboxesFreeLevel().
+ (++) Then request transmission of a message using
+ HAL_CAN_AddTxMessage().
+
+
+ *** Interrupt mode operation ***
+ ================================
+ [..]
+ (#) Notifications are activated using HAL_CAN_ActivateNotification()
+ function. Then, the process can be controlled through the
+ available user callbacks: HAL_CAN_xxxCallback(), using same APIs
+ HAL_CAN_GetRxMessage() and HAL_CAN_AddTxMessage().
+
+ (#) Notifications can be deactivated using
+ HAL_CAN_DeactivateNotification() function.
+
+ (#) Special care should be taken for CAN_IT_RX_FIFO0_MSG_PENDING and
+ CAN_IT_RX_FIFO1_MSG_PENDING notifications. These notifications trig
+ the callbacks HAL_CAN_RxFIFO0MsgPendingCallback() and
+ HAL_CAN_RxFIFO1MsgPendingCallback(). User has two possible options
+ here.
+ (++) Directly get the Rx message in the callback, using
+ HAL_CAN_GetRxMessage().
+ (++) Or deactivate the notification in the callback without
+ getting the Rx message. The Rx message can then be got later
+ using HAL_CAN_GetRxMessage(). Once the Rx message have been
+ read, the notification can be activated again.
+
+
+ *** Sleep mode ***
+ ==================
+ [..]
+ (#) The CAN peripheral can be put in sleep mode (low power), using
+ HAL_CAN_RequestSleep(). The sleep mode will be entered as soon as the
+ current CAN activity (transmission or reception of a CAN frame) will
+ be completed.
+
+ (#) A notification can be activated to be informed when the sleep mode
+ will be entered.
+
+ (#) It can be checked if the sleep mode is entered using
+ HAL_CAN_IsSleepActive().
+ Note that the CAN state (accessible from the API HAL_CAN_GetState())
+ is HAL_CAN_STATE_SLEEP_PENDING as soon as the sleep mode request is
+ submitted (the sleep mode is not yet entered), and become
+ HAL_CAN_STATE_SLEEP_ACTIVE when the sleep mode is effective.
+
+ (#) The wake-up from sleep mode can be trigged by two ways:
+ (++) Using HAL_CAN_WakeUp(). When returning from this function,
+ the sleep mode is exited (if return status is HAL_OK).
+ (++) When a start of Rx CAN frame is detected by the CAN peripheral,
+ if automatic wake up mode is enabled.

+ * @brief CEC HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the High Definition Multimedia Interface
+ * Consumer Electronics Control Peripheral (CEC).
+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral Control functions
+ *

+ @verbatim
+ ===============================================================================
+ ##### How to use this driver #####
+ ===============================================================================
+ [..]
+ The CEC HAL driver can be used as follow:
+
+ (#) Declare a CEC_HandleTypeDef handle structure.
+ (#) Initialize the CEC low level resources by implementing the HAL_CEC_MspInit ()API:
+ (##) Enable the CEC interface clock.
+ (##) CEC pins configuration:
+ (+) Enable the clock for the CEC GPIOs.
+ (+) Configure these CEC pins as alternate function pull-up.
+ (##) NVIC configuration if you need to use interrupt process (HAL_CEC_Transmit_IT()
+ and HAL_CEC_Receive_IT() APIs):
+ (+) Configure the CEC interrupt priority.
+ (+) Enable the NVIC CEC IRQ handle.
+ (@) The specific CEC interrupts (Transmission complete interrupt,
+ RXNE interrupt and Error Interrupts) will be managed using the macros
+ __HAL_CEC_ENABLE_IT() and __HAL_CEC_DISABLE_IT() inside the transmit
+ and receive process.
+
+ (#) Program the Signal Free Time (SFT) and SFT option, Tolerance, reception stop in
+ in case of Bit Rising Error, Error-Bit generation conditions, device logical
+ address and Listen mode in the hcec Init structure.
+
+ (#) Initialize the CEC registers by calling the HAL_CEC_Init() API.
+
+ (@) This API (HAL_CEC_Init()) configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+ by calling the customed HAL_CEC_MspInit() API.

+ * @brief COMP HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the COMP peripheral:
+ * + Initialization/de-initialization functions
+ * + I/O operation functions
+ * + Peripheral Control functions
+ * + Peripheral State functions
+ *
+ @verbatim
+================================================================================
+ ##### COMP Peripheral features #####
+================================================================================
+
+ [..]
+ The STM32F0xx device family integrates up to 2 analog comparators COMP1 and COMP2:
+ (+) The non inverting input and inverting input can be set to GPIO pins.
+
+ (+) The COMP output is available using HAL_COMP_GetOutputLevel()
+ and can be set on GPIO pins.
+
+ (+) The COMP output can be redirected to embedded timers (TIM1, TIM2 and TIM3).
+
+ (+) The comparators COMP1 and COMP2 can be combined in window mode.
+
+ (+) The comparators have interrupt capability with wake-up
+ from Sleep and Stop modes (through the EXTI controller):
+ (++) COMP1 is internally connected to EXTI Line 21
+ (++) COMP2 is internally connected to EXTI Line 22
+
+ (+) From the corresponding IRQ handler, the right interrupt source can be retrieved with the
+ macros __HAL_COMP_COMP1_EXTI_GET_FLAG() and __HAL_COMP_COMP2_EXTI_GET_FLAG().
+
+
+ ##### How to use this driver #####
+================================================================================
+ [..]
+ This driver provides functions to configure and program the Comparators of STM32F05x, STM32F07x and STM32F09x devices.
+
+ To use the comparator, perform the following steps:
+
+ (#) Fill in the HAL_COMP_MspInit() to
+ (++) Configure the comparator input in analog mode using HAL_GPIO_Init()
+ (++) Configure the comparator output in alternate function mode using HAL_GPIO_Init() to map the comparator
+ output to the GPIO pin
+ (++) If required enable the COMP interrupt by configuring and enabling EXTI line in Interrupt mode and
+ selecting the desired sensitivity level using HAL_GPIO_Init() function. After that enable the comparator
+ interrupt vector using HAL_NVIC_EnableIRQ() function.
+
+ (#) Configure the comparator using HAL_COMP_Init() function:
+ (++) Select the inverting input (input minus)
+ (++) Select the non inverting input (input plus)
+ (++) Select the output polarity
+ (++) Select the output redirection
+ (++) Select the hysteresis level
+ (++) Select the power mode
+ (++) Select the event/interrupt mode
+ (++) Select the window mode
+
+ -@@- HAL_COMP_Init() calls internally __HAL_RCC_SYSCFG_CLK_ENABLE() in order
+ to access the comparator(s) registers.
+
+ (#) Enable the comparator using HAL_COMP_Start() function or HAL_COMP_Start_IT() function for interrupt mode.
+
+ (#) Use HAL_COMP_TriggerCallback() and/or HAL_COMP_GetOutputLevel() functions
+ to manage comparator outputs (event/interrupt triggered and output level).
+
+ (#) Disable the comparator using HAL_COMP_Stop() or HAL_COMP_Stop_IT()
+ function.
+
+ (#) De-initialize the comparator using HAL_COMP_DeInit() function.
+
+ (#) For safety purposes comparator(s) can be locked using HAL_COMP_Lock() function.
+ Only a MCU reset can reset that protection.

+ *** How to configure Systick using CORTEX HAL driver ***
+ ========================================================
+ [..]
+ Setup SysTick Timer for time base.
+
+ (+) 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 (0x03).
+ (++) 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_SYSTICK_CLKSourceConfig(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
+ HAL_SYSTICK_Config() function call. The HAL_SYSTICK_CLKSourceConfig() macro is defined
+ inside the stm32f0xx_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

+ ==============================================================================
+ ##### DAC Peripheral features #####
+ ==============================================================================
+ [..]
+ *** DAC Channels ***
+ ====================
+ [..]
+ STM32F0 devices integrates no, one or two 12-bit Digital Analog Converters.
+ STM32F05x devices have one converter (channel1)
+ STM32F07x & STM32F09x devices have two converters (i.e. channel1 & channel2)
+
+ When 2 converters are present (i.e. channel1 & channel2) they
+ can be used independently or simultaneously (dual mode):
+ (#) DAC channel1 with DAC_OUT1 (PA4) as output
+ (#) DAC channel2 with DAC_OUT2 (PA5) as output
+
+ *** 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, TIM3, TIM6, and TIM15
+ (DAC_TRIGGER_T2_TRGO, DAC_TRIGGER_T3_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.
+
+ *** GPIO configurations guidelines ***
+ =====================
+ [..]
+ When a DAC channel is used (ex channel1 on PA4) and the other is not
+ (ex channel1 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 correspondance ***
+ ================================================
+ [..]
+ 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 channel3 which must be
+ already configured
+ (#) DAC channel2 : mapped on DMA1 channel4 which must be
+ already configured
+
+ (@) For Dual mode and specific signal (Triangle and noise) generation please
+ refer to Extended Features Driver description
+ STM32F0 devices with one channel (one converting capability) does not
+ support Dual mode and specific signal (Triangle and noise) generation.
+
+ ##### 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
+ (+) 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()
+ function is executed and user can add his own code by customization of function pointer
+ HAL_DAC_DMAUnderrunCallbackCh1() or HAL_DACEx_DMAUnderrunCallbackCh2() and
+ add his own code by customization of function pointer HAL_DAC_ErrorCallbackCh1()
+ (+) Stop the DAC peripheral using HAL_DAC_Stop_DMA()
+
+ *** DAC HAL driver macros list ***
+ =============================================
+ [..]
+ Below the list of most used macros in DAC HAL driver.
+
+ (+) __HAL_DAC_ENABLE : Enable the DAC peripheral
+ (+) __HAL_DAC_DISABLE : Disable the DAC peripheral
+ (+) __HAL_DAC_CLEAR_FLAG: Clear the DAC's pending flags
+ (+) __HAL_DAC_GET_FLAG: Get the selected DAC's flag status
+
+ [..]
+ (@) You can refer to the DAC HAL driver header file for more useful macros

+ * @brief DMA HAL module driver.
+ *
+ * This file provides firmware functions to manage the following
+ * functionalities of the Direct Memory Access (DMA) peripheral:
+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral State and errors functions
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#) 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 Reference manual for connection between peripherals
+ and DMA requests .
+
+ (#) For a given Channel, program the required configuration through the following parameters:
+ 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_Channel_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 by customization of function pointer XferCpltCallback and
+ XferErrorCallback (i.e a member of DMA handle structure).
+
+ *** DMA HAL driver macros list ***
+ =============================================
+ [..]
+ Below the list of most used macros in DMA HAL driver.
+
+ [..]
+ (@) You can refer to the DMA HAL driver header file for more useful macros

+ * @brief FLASH HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the internal FLASH memory:
+ * + Program operations functions
+ * + Memory Control functions
+ * + Peripheral State functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### 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 STM32F0xx devices.
+
+ (#) FLASH Memory I/O Programming functions: this group includes all needed
+ functions to erase and program the main memory:
+ (++) Lock and Unlock the FLASH interface
+ (++) Erase function: Erase page, erase all pages
+ (++) Program functions: half word, word and doubleword
+ (#) FLASH Option Bytes Programming functions: this group includes all needed
+ functions to manage the Option Bytes:
+ (++) Lock and Unlock the Option Bytes
+ (++) Set/Reset the write protection
+ (++) Set the Read protection Level
+ (++) Program the user Option Bytes
+ (++) Launch the Option Bytes loader
+ (++) Erase Option Bytes
+ (++) Program the data Option Bytes
+ (++) Get the Write protection.
+ (++) Get the user option bytes.
+
+ (#) Interrupts and flags management functions : this group
+ includes all needed functions to:
+ (++) Handle FLASH interrupts
+ (++) Wait for last FLASH operation according to its status
+ (++) Get error flag status
+
+ [..] In addition to these function, this driver includes a set of macros allowing
+ to handle the following operations:
+
+ (+) Set/Get the latency
+ (+) Enable/Disable the prefetch buffer
+ (+) Enable/Disable the FLASH interrupts
+ (+) Monitor the FLASH flags status

+ * @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 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
+ (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 : __HAL_RCC_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.
+ (++) In alternate mode is selection, 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 PF0 and PF1, respectively, when the HSE oscillator is off.
+ The HSE has priority over the GPIO function.

+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The I2C HAL driver can be used as follows:
+
+ (#) Declare a I2C_HandleTypeDef handle structure, for example:
+ I2C_HandleTypeDef hi2c;
+
+ (#)Initialize the I2C low level resources by implementing the HAL_I2C_MspInit() API:
+ (##) Enable the I2Cx interface clock
+ (##) I2C pins configuration
+ (+++) Enable the clock for the I2C GPIOs
+ (+++) Configure I2C pins as alternate function open-drain
+ (##) NVIC configuration if you need to use interrupt process
+ (+++) Configure the I2Cx interrupt priority
+ (+++) Enable the NVIC I2C IRQ Channel
+ (##) DMA Configuration if you need to use DMA process
+ (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive channel
+ (+++) Enable the DMAx interface clock using
+ (+++) Configure the DMA handle parameters
+ (+++) Configure the DMA Tx or Rx channel
+ (+++) Associate the initialized DMA handle to the hi2c DMA Tx or Rx handle
+ (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on
+ the DMA Tx or Rx channel
+
+ (#) Configure the Communication Clock Timing, Own Address1, Master Addressing mode, Dual Addressing mode,
+ Own Address2, Own Address2 Mask, General call and Nostretch mode in the hi2c Init structure.
+
+ (#) Initialize the I2C registers by calling the HAL_I2C_Init(), configures also the low level Hardware
+ (GPIO, CLOCK, NVIC...etc) by calling the customized HAL_I2C_MspInit(&hi2c) API.
+
+ (#) To check if target device is ready for communication, use the function HAL_I2C_IsDeviceReady()
+
+ (#) For I2C IO and IO MEM operations, three operation modes are available within this driver :

+ * @brief I2S HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the Integrated Interchip Sound (I2S) peripheral:
+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral State and Errors functions
+ @verbatim
+ ===============================================================================
+ ##### How to use this driver #####
+ ===============================================================================
+ [..]
+ The I2S HAL driver can be used as follow:
+
+ (#) Declare a I2S_HandleTypeDef handle structure.
+ (#) Initialize the I2S low level resources by implement the HAL_I2S_MspInit() API:
+ (##) Enable the SPIx interface clock.
+ (##) I2S pins configuration:
+ (+++) Enable the clock for the I2S GPIOs.
+ (+++) Configure these I2S pins as alternate function pull-up.
+ (##) NVIC configuration if you need to use interrupt process (HAL_I2S_Transmit_IT()
+ and HAL_I2S_Receive_IT() APIs).
+ (+++) Configure the I2Sx interrupt priority.
+ (+++) Enable the NVIC I2S IRQ handle.
+ (##) DMA Configuration if you need to use DMA process (HAL_I2S_Transmit_DMA()
+ and HAL_I2S_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 initilalized DMA handle to the I2S DMA Tx/Rx handle.
+ (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the
+ DMA Tx/Rx Channel.
+
+ (#) Program the Mode, Standard, Data Format, MCLK Output, Audio frequency and Polarity
+ using HAL_I2S_Init() function.
+
+ -@- The specific I2S interrupts (Transmission complete interrupt,
+ RXNE interrupt and Error Interrupts) will be managed using the macros
+ __HAL_I2S_ENABLE_IT() and __HAL_I2S_DISABLE_IT() inside the transmit and receive process.
+ -@- Make sure that either:
+ (+@) External clock source is configured after setting correctly
+ the define constant EXTERNAL_CLOCK_VALUE in the stm32f0xx_hal_conf.h file.
+
+ (#) Three mode of operations are available within this driver :
+
+ *** Polling mode IO operation ***
+ =================================
+ [..]
+ (+) Send an amount of data in blocking mode using HAL_I2S_Transmit()
+ (+) Receive an amount of data in blocking mode using HAL_I2S_Receive()
+
+ *** Interrupt mode IO operation ***
+ ===================================
+ [..]
+ (+) Send an amount of data in non blocking mode using HAL_I2S_Transmit_IT()
+ (+) At transmission end of half transfer HAL_I2S_TxHalfCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_I2S_TxHalfCpltCallback

+ add his own code by customization of function pointer HAL_I2S_RxCpltCallback
+ (+) In case of transfer Error, HAL_I2S_ErrorCallback() function is executed and user can
+ add his own code by customization of function pointer HAL_I2S_ErrorCallback
+
+ *** DMA mode IO operation ***
+ ==============================
+ [..]
+ (+) Send an amount of data in non blocking mode (DMA) using HAL_I2S_Transmit_DMA()
+ (+) At transmission end of half transfer HAL_I2S_TxHalfCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_I2S_TxHalfCpltCallback
+ (+) At transmission end of transfer HAL_I2S_TxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_I2S_TxCpltCallback

+
+ *** I2S HAL driver macros list ***
+ =============================================
+ [..]
+ Below the list of most used macros in I2S HAL driver.
+
+ (+) __HAL_I2S_ENABLE: Enable the specified SPI peripheral (in I2S mode)
+ (+) __HAL_I2S_DISABLE: Disable the specified SPI peripheral (in I2S mode)
+ (+) __HAL_I2S_ENABLE_IT : Enable the specified I2S interrupts
+ (+) __HAL_I2S_DISABLE_IT : Disable the specified I2S interrupts

+ ##### IO operation functions #####

+ [..]
+ This subsection provides a set of functions allowing to manage the I2S data
+ transfers.
+
+ (#) There are two modes of transfer:
+ (++) Blocking mode : The communication is performed in the polling mode.
+ The 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 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.
+
+ (#) Blocking mode functions are :
+ (++) HAL_I2S_Transmit()
+ (++) HAL_I2S_Receive()
+
+ (#) No-Blocking mode functions with Interrupt are :
+ (++) HAL_I2S_Transmit_IT()
+ (++) HAL_I2S_Receive_IT()
+
+ (#) No-Blocking mode functions with DMA are :
+ (++) HAL_I2S_Transmit_DMA()
+ (++) HAL_I2S_Receive_DMA()
+
+ (#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
+ (++) HAL_I2S_TxCpltCallback()
+ (++) HAL_I2S_RxCpltCallback()
+ (++) HAL_I2S_ErrorCallback()

+ @verbatim
+ ==============================================================================
+ ##### 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
+ in setting the associated USART or UART in IRDA mode:
+ (++) Enable the USARTx/UARTx interface clock.
+ (++) USARTx/UARTx pins configuration:
+ (+++) Enable the clock for the USARTx/UARTx GPIOs.
+ (+++) Configure these USARTx/UARTx pins (TX as alternate function pull-up, RX as alternate function Input).
+ (++) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
+ and HAL_IRDA_Receive_IT() APIs):
+ (+++) Configure the USARTx/UARTx interrupt priority.
+ (+++) Enable the NVIC USARTx/UARTx IRQ handle.
+ (+++) 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.
+
+ (++) 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.
+
+ (#) Program the Baud Rate, Word Length and Parity and Mode(Receiver/Transmitter),
+ the normal or low power mode and the clock prescaler in the hirda handle 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 half of 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()
+ (+) At reception half of transfer HAL_IRDA_RxHalfCpltCallback() is executed and user can
+ add his own code by customization of function pointer HAL_IRDA_RxHalfCpltCallback()
+ (+) 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()
+
+ *** 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 or not the specified IRDA interrupt is enabled
+
+ [..]
+ (@) You can refer to the IRDA HAL driver header file for more useful macros

+ ===============================================================================
+ ##### IO operation functions #####
+ ===============================================================================
+ [..]
+ 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 mode 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.

+ * @brief IWDG HAL module driver.
+ * 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 @40KHz (LSI): ~0.1ms / ~26.2s
+ The IWDG timeout may vary due to LSI frequency dispersion. STM32F0xx
+ devices provide the capability to measure the LSI frequency (LSI clock
+ connected internally to TIM16 CH1 input capture). The measured value
+ can be used to have an IWDG timeout with an acceptable accuracy.
+
+ ##### 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 &
+ IWDG_WINR.
+ (++) 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"
+ (++) Depending on window parameter:
+ (+++) If Window Init parameter is same as Window register value,
+ nothing more is done but reload counter value in order to exit
+ function withy exact time base.
+ (+++) Else modify Window register. This will automatically reload
+ watchdog counter.
+
+ (#) 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

+
+ *** WakeUp pin configuration ***
+ ================================
+ [..]
+ (+) WakeUp pin is used to wakeup the system from Standby mode. This pin is
+ forced in input pull down configuration and is active on rising edges.
+ (+) There are two WakeUp pins, and up to eight Wakeup pins on STM32F07x & STM32F09x devices.
+ (++)WakeUp Pin 1 on PA.00.
+ (++)WakeUp Pin 2 on PC.13.
+ (++)WakeUp Pin 3 on PE.06.(STM32F07x/STM32F09x)
+ (++)WakeUp Pin 4 on PA.02.(STM32F07x/STM32F09x)
+ (++)WakeUp Pin 5 on PC.05.(STM32F07x/STM32F09x)
+ (++)WakeUp Pin 6 on PB.05.(STM32F07x/STM32F09x)
+ (++)WakeUp Pin 7 on PB.15.(STM32F07x/STM32F09x)
+ (++)WakeUp Pin 8 on PF.02.(STM32F07x/STM32F09x)
+
+ *** Low Power modes configuration ***
+ =====================================
+ [..]
+ The devices feature 3 low-power modes:
+ (+) Sleep mode: Cortex-M0 core stopped, peripherals kept running.
+ (+) Stop mode: all clocks are stopped, regulator running, regulator
+ in low power mode
+ (+) Standby mode: 1.2V domain powered off (mode not available on STM32F0x8 devices).
+
+ *** 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.
+
+ *** Stop mode ***
+ =================
+ [..]
+ In Stop mode, all clocks in the 1.8V domain are stopped, the PLL, the HSI,
+ and the HSE RC oscillators are disabled. Internal SRAM and register contents
+ are preserved.
+ The voltage regulator can be configured either in normal or low-power mode.
+ To minimize the consumption.
+
+ (+) Entry:
+ The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_MAINREGULATOR_ON, PWR_STOPENTRY_WFI )
+ function with:
+ (++) Main regulator ON.
+ (++) Low Power regulator ON.
+ (++) PWR_STOPENTRY_WFI: enter STOP mode with WFI instruction
+ (++) PWR_STOPENTRY_WFE: enter STOP mode with WFE instruction
+ (+) Exit:
+ (++) Any EXTI Line (Internal or External) configured in Interrupt/Event mode.
+ (++) Some specific communication peripherals (CEC, USART, I2C) interrupts,
+ when programmed in wakeup mode (the peripheral must be
+ programmed in wakeup mode and the corresponding interrupt vector
+ must be enabled in the NVIC)
+
+ *** Standby mode ***
+ ====================
+ [..]
+ The Standby mode allows to achieve the lowest power consumption. It is based
+ on the Cortex-M0 deep sleep mode, with the voltage regulator disabled.
+ The 1.8V domain is consequently powered off. The PLL, 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.
+ The voltage regulator is OFF.
+
+ (+) Entry:
+ (++) The Standby mode is entered using the HAL_PWR_EnterSTANDBYMode() function.
+ (+) Exit:
+ (++) WKUP pin rising edge, RTC alarm (Alarm A), 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 and Standby modes
+
+ (++) To wake up from the Stop mode with an RTC alarm event, it is necessary to
+ configure the RTC to generate the RTC alarm using the HAL_RTC_SetAlarm_IT() function.
+
+ (++) To wake up from the Stop mode with an RTC Tamper or time stamp event, it
+ is necessary to configure the RTC to detect the tamper or time stamp event using the
+ HAL_RTC_SetTimeStamp_IT() or HAL_RTC_SetTamper_IT() functions.
+
+ (++) To wake up from the Stop mode with an RTC WakeUp event, it is necessary to
+ configure the RTC to generate the RTC WakeUp event using the HAL_RTC_SetWakeUpTimer_IT() function.
+
+ (+) Comparator auto-wakeup (AWU) from the Stop mode
+
+ (++) To wake up from the Stop mode with a comparator wakeup event, it is necessary to:
+ (+++) Configure the EXTI Line associated with the comparator (example EXTI Line 22 for comparator 2)
+ to be sensitive to to the selected edges (falling, rising or falling
+ and rising) (Interrupt or Event modes) using the EXTI_Init() function.
+ (+++) Configure the comparator to generate the event.

+ * + Initialization and de-initialization functions
+ * + Peripheral Control functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### RCC specific features #####
+ ==============================================================================
+ [..]
+ After reset the device is running from Internal High Speed oscillator
+ (HSI 8MHz) with Flash 0 wait state, Flash prefetch buffer is enabled,
+ and all peripherals are off except internal SRAM, Flash and JTAG.
+ (+) There is no prescaler on High speed (AHB) and Low speed (APB) buses;
+ all peripherals mapped on these buses are running at HSI speed.
+ (+) The clock for all peripherals is switched off, except the SRAM and FLASH.
+ (+) All GPIOs are in input floating state, except the JTAG pins which
+ are assigned to be used for debug purpose.
+ [..] Once the device started from reset, the user application has to:
+ (+) Configure the clock source to be used to drive the System clock
+ (if the application needs higher frequency/performance)
+ (+) Configure the System clock frequency and Flash settings
+ (+) Configure the AHB and APB buses prescalers
+ (+) Enable the clock for the peripheral(s) to be used
+ (+) Configure the clock source(s) for peripherals whose clocks are not
+ derived from the System clock (RTC, ADC, I2C, USART, TIM, USB FS, etc..)
+
+ ##### 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 __HAL_RCC_PPP_CLK_ENABLE() macro.

+ (HSE, HSI, HSI14, HSI48, LSE, LSI, PLL, CSS and MCO) and the System buses clocks (SYSCLK,
+ AHB and APB1).
+
+ [..] Internal/external clock and PLL configuration
+ (#) HSI (high-speed internal), 8 MHz factory-trimmed RC used directly or through
+ the PLL as System clock source.
+ The HSI clock can be used also to clock the USART and I2C peripherals.
+
+ (#) HSI14 (high-speed internal), 14 MHz factory-trimmed RC used directly to clock
+ the ADC peripheral.
+
+ (#) LSI (low-speed internal), ~40 KHz low consumption RC used as IWDG and/or RTC
+ clock source.
+
+ (#) HSE (high-speed external), 4 to 32 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, HSI48 or HSE), featuring different output clocks:
+ (++) The first output is used to generate the high speed system clock (up to 48 MHz)
+ (++) The second output is used to generate the clock for the USB FS (48 MHz)
+ (++) The third output may be used to generate the clock for the TIM, I2C and USART
+ peripherals (up to 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 HSI and an interrupt
+ is generated if enabled. The interrupt is linked to the Cortex-M0 NMI
+ (Non-Maskable Interrupt) exception vector.
+
+ (#) MCO (microcontroller clock output), used to output SYSCLK, HSI, HSE, LSI, LSE or PLL
+ clock (divided by 2) output on pin (such as PA8 pin).
+
+ [..] System, AHB and APB buses clocks configuration
+ (#) Several clock sources can be used to drive the System clock (SYSCLK): HSI,
+ HSE and PLL.
+ The AHB clock (HCLK) is derived from System clock through configurable
+ prescaler and used to clock the CPU, memory and peripherals mapped
+ on AHB bus (DMA, GPIO...). APB1 (PCLK1) clock is derived
+ from AHB clock through configurable prescalers and used to clock
+ the peripherals mapped on these buses. You can use
+ "@ref HAL_RCC_GetSysClockFreq()" function to retrieve the frequencies of these clocks.
+
+ (#) All the peripheral clocks are derived from the System clock (SYSCLK) except:
+ (++) The FLASH program/erase clock which is always HSI 8MHz clock.
+ (++) The USB 48 MHz clock which is derived from the PLL VCO clock.
+ (++) The USART clock which can be derived as well from HSI 8MHz, LSI or LSE.
+ (++) The I2C clock which can be derived as well from HSI 8MHz clock.
+ (++) The ADC clock which is derived from PLL output.
+ (++) The RTC clock which is derived from the LSE, LSI or 1 MHz HSE_RTC
+ (HSE divided by a programmable prescaler). The System clock (SYSCLK)
+ frequency must be higher or equal to the RTC clock frequency.
+ (++) IWDG clock which is always the LSI clock.
+
+ (#) For the STM32F0xx devices, the maximum frequency of the SYSCLK, HCLK and PCLK1 is 48 MHz,
+ Depending on the SYSCLK frequency, the flash latency should be adapted accordingly.
+
+ (#) After reset, the System clock source is the HSI (8 MHz) with 0 WS and

+ ===============================================================================
+ ##### Extended Clock Recovery System Control functions #####
+ ===============================================================================
+ [..]
+ For devices with Clock Recovery System feature (CRS), RCC Extention HAL driver can be used as follows:
+
+ (#) In System clock config, HSI48 needs to be enabled
+
+ (#) Enable CRS clock in IP MSP init which will use CRS functions
+
+ (#) Call CRS functions as follows:
+ (##) Prepare synchronization configuration necessary for HSI48 calibration
+ (+++) Default values can be set for frequency Error Measurement (reload and error limit)
+ and also HSI48 oscillator smooth trimming.
+ (+++) Macro @ref __HAL_RCC_CRS_RELOADVALUE_CALCULATE can be also used to calculate
+ directly reload value with target and synchronization frequencies values
+ (##) Call function @ref HAL_RCCEx_CRSConfig which
+ (+++) Reset CRS registers to their default values.
+ (+++) Configure CRS registers with synchronization configuration
+ (+++) Enable automatic calibration and frequency error counter feature
+ Note: When using USB LPM (Link Power Management) and the device is in Sleep mode, the
+ periodic USB SOF will not be generated by the host. No SYNC signal will therefore be
+ provided to the CRS to calibrate the HSI48 on the run. To guarantee the required clock
+ precision after waking up from Sleep mode, the LSE or reference clock on the GPIOs
+ should be used as SYNC signal.
+
+ (##) A polling function is provided to wait for complete synchronization
+ (+++) Call function @ref HAL_RCCEx_CRSWaitSynchronization()
+ (+++) According to CRS status, user can decide to adjust again the calibration or continue
+ application if synchronization is OK
+
+ (#) User can retrieve information related to synchronization in calling function
+ @ref HAL_RCCEx_CRSGetSynchronizationInfo()
+
+ (#) Regarding synchronization status and synchronization information, user can try a new calibration
+ in changing synchronization configuration and call again HAL_RCCEx_CRSConfig.
+ Note: When the SYNC event is detected during the downcounting phase (before reaching the zero value),
+ it means that the actual frequency is lower than the target (and so, that the TRIM value should be
+ incremented), while when it is detected during the upcounting phase it means that the actual frequency
+ is higher (and that the TRIM value should be decremented).
+
+ (#) In interrupt mode, user can resort to the available macros (__HAL_RCC_CRS_XXX_IT). Interrupts will go
+ through CRS Handler (RCC_IRQn/RCC_IRQHandler)
+ (++) Call function @ref HAL_RCCEx_CRSConfig()
+ (++) Enable RCC_IRQn (thanks to NVIC functions)
+ (++) Enable CRS interrupt (@ref __HAL_RCC_CRS_ENABLE_IT)
+ (++) Implement CRS status management in the following user callbacks called from
+ HAL_RCCEx_CRS_IRQHandler():
+ (+++) @ref HAL_RCCEx_CRS_SyncOkCallback()
+ (+++) @ref HAL_RCCEx_CRS_SyncWarnCallback()
+ (+++) @ref HAL_RCCEx_CRS_ExpectedSyncCallback()
+ (+++) @ref HAL_RCCEx_CRS_ErrorCallback()
+
+ (#) To force a SYNC EVENT, user can use the function @ref HAL_RCCEx_CRSSoftwareSynchronizationGenerate().
+ This function can be called before calling @ref HAL_RCCEx_CRSConfig (for instance in Systick handler)

+ * @brief RTC HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the Real Time Clock (RTC) peripheral:
+ * + Initialization and de-initialization functions
+ * + RTC Time and Date functions
+ * + RTC Alarm functions
+ * + Peripheral Control functions
+ * + Peripheral State functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### 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 alarm (Alarm A),
+ RTC wake-up, 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-wake-up mode), by using the RTC alarm
+ or the RTC wake-up events.
+ [..] The RTC provides a programmable time base for waking up from the
+ Stop or Standby mode at regular intervals.
+ Wake-up from STOP and STANDBY modes is possible only when the RTC clock source
+ is LSE or LSI.

+ ===============================================================================
+ ##### Initialization and de-initialization 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 15-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 wake-up 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 Wake-up 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.
+ (@) Not available on F030x4/x6/x8 and F070x6
+
+ *** TimeStamp configuration ***
+ ===============================
+ [..]
+ (+) Configure the RTC_AF 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.
+
+ *** 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 in interrupt
+ mode using HAL_RTCEx_SetTamper_IT() function.
+
+ *** 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.
+ (@) Not available on F030x6/x8/xC and F070x6/xB (F0xx Value Line devices)

+ * + Peripheral Control functions
+ * + Peripheral State and Error functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The SMARTCARD HAL driver can be used as follows:
+
+ (#) Declare a SMARTCARD_HandleTypeDef handle structure (eg. SMARTCARD_HandleTypeDef hsmartcard).
+ (#) Associate a USART to the SMARTCARD handle hsmartcard.
+ (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
+ (++) Enable the USARTx interface clock.
+ (++) USART pins configuration:
+ (+++) Enable the clock for the USART GPIOs.
+ (+++) Configure the USART pins (TX as alternate function pull-up, RX as alternate function Input).
+ (++) 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.
+
+ (#) Program the Baud Rate, Parity, Mode(Receiver/Transmitter), clock enabling/disabling and accordingly,
+ the clock parameters (parity, phase, last bit), prescaler value, guard time and NACK on transmission
+ error enabling or disabling in the hsmartcard handle Init structure.
+
+ (#) If required, program SMARTCARD advanced features (TX/RX pins swap, TimeOut, auto-retry counter,...)
+ in the hsmartcard handle AdvancedInit structure.
+
+ (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
+ (++) This API configures 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
+ add his own code by customization of function pointer HAL_SMARTCARD_RxCpltCallback()
+ (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback()
+
+ *** DMA mode IO operation ***
+ ==============================
+ [..]
+ (+) Send an amount of data in non-blocking mode (DMA) using HAL_SMARTCARD_Transmit_DMA()
+ (+) 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 (DMA) using HAL_SMARTCARD_Receive_DMA()
+ (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback() is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_RxCpltCallback()
+ (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback()
+
+ *** SMARTCARD HAL driver macros list ***
+ ========================================
+ [..]
+ Below the list of most used macros in SMARTCARD HAL driver.
+
+ (+) __HAL_SMARTCARD_GET_FLAG : Check whether or not the specified SMARTCARD flag is set
+ (+) __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
+ (+) __HAL_SMARTCARD_GET_IT_SOURCE: Check whether or not the specified SMARTCARD interrupt is enabled

+ ##### Initialization and Configuration functions #####
+ ==============================================================================
+ [..]
+ This subsection provides a set of functions allowing to initialize the USARTx
+ associated to the SmartCard.
+ [..]
+ 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.
+ [..]
+ (+) These parameters can be configured:
+ (++) Baud Rate
+ (++) Parity: should be enabled
+ (++) Receiver/transmitter modes
+ (++) Synchronous mode (and if enabled, phase, polarity and last bit parameters)
+ (++) Prescaler value
+ (++) Guard bit time
+ (++) NACK enabling or disabling on transmission error
+
+ (+) The following advanced features can be configured as well:
+ (++) TX and/or RX pin level inversion
+ (++) data logical level inversion

+ ==============================================================================
+ ##### 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, the relevant API's 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.

+ * + IO operation functions
+ * + Peripheral State and Errors functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The SMBUS HAL driver can be used as follows:
+
+ (#) Declare a SMBUS_HandleTypeDef handle structure, for example:
+ SMBUS_HandleTypeDef hsmbus;
+
+ (#)Initialize the SMBUS low level resources by implementing the HAL_SMBUS_MspInit() API:
+ (##) Enable the SMBUSx interface clock
+ (##) SMBUS pins configuration
+ (+++) Enable the clock for the SMBUS GPIOs
+ (+++) Configure SMBUS pins as alternate function open-drain
+ (##) NVIC configuration if you need to use interrupt process
+ (+++) Configure the SMBUSx interrupt priority
+ (+++) Enable the NVIC SMBUS IRQ Channel
+
+ (#) Configure the Communication Clock Timing, Bus Timeout, Own Address1, Master Addressing mode,
+ Dual Addressing mode, Own Address2, Own Address2 Mask, General call, Nostretch mode,
+ Peripheral mode and Packet Error Check mode in the hsmbus Init structure.
+
+ (#) Initialize the SMBUS registers by calling the HAL_SMBUS_Init() API:
+ (++) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+ by calling the customized HAL_SMBUS_MspInit(&hsmbus) API.
+
+ (#) To check if target device is ready for communication, use the function HAL_SMBUS_IsDeviceReady()
+
+ (#) For SMBUS IO operations, only one mode of operations is available within this driver
+
+ *** Interrupt mode IO operation ***
+ ===================================
+ [..]
+ (+) Transmit in master/host SMBUS mode an amount of data in non-blocking mode using HAL_SMBUS_Master_Transmit_IT()
+ (++) At transmission end of transfer HAL_SMBUS_MasterTxCpltCallback() is executed and user can
+ add his own code by customization of function pointer HAL_SMBUS_MasterTxCpltCallback()
+ (+) Receive in master/host SMBUS mode an amount of data in non-blocking mode using HAL_SMBUS_Master_Receive_IT()
+ (++) At reception end of transfer HAL_SMBUS_MasterRxCpltCallback() is executed and user can
+ add his own code by customization of function pointer HAL_SMBUS_MasterRxCpltCallback()
+ (+) Abort a master/host SMBUS process communication with Interrupt using HAL_SMBUS_Master_Abort_IT()
+ (++) The associated previous transfer callback is called at the end of abort process
+ (++) mean HAL_SMBUS_MasterTxCpltCallback() in case of previous state was master transmit
+ (++) mean HAL_SMBUS_MasterRxCpltCallback() in case of previous state was master receive
+ (+) Enable/disable the Address listen mode in slave/device or host/slave SMBUS mode
+ using HAL_SMBUS_EnableListen_IT() HAL_SMBUS_DisableListen_IT()
+ (++) When address slave/device SMBUS match, HAL_SMBUS_AddrCallback() is executed and user can
+ add his own code to check the Address Match Code and the transmission direction request by master/host (Write/Read).
+ (++) At Listen mode end HAL_SMBUS_ListenCpltCallback() is executed and user can
+ add his own code by customization of function pointer HAL_SMBUS_ListenCpltCallback()
+ (+) Transmit in slave/device SMBUS mode an amount of data in non-blocking mode using HAL_SMBUS_Slave_Transmit_IT()
+ (++) At transmission end of transfer HAL_SMBUS_SlaveTxCpltCallback() is executed and user can
+ add his own code by customization of function pointer HAL_SMBUS_SlaveTxCpltCallback()
+ (+) Receive in slave/device SMBUS mode an amount of data in non-blocking mode using HAL_SMBUS_Slave_Receive_IT()
+ (++) At reception end of transfer HAL_SMBUS_SlaveRxCpltCallback() is executed and user can
+ add his own code by customization of function pointer HAL_SMBUS_SlaveRxCpltCallback()
+ (+) Enable/Disable the SMBUS alert mode using HAL_SMBUS_EnableAlert_IT() HAL_SMBUS_DisableAlert_IT()
+ (++) When SMBUS Alert is generated HAL_SMBUS_ErrorCallback() is executed and user can
+ add his own code by customization of function pointer HAL_SMBUS_ErrorCallback()
+ to check the Alert Error Code using function HAL_SMBUS_GetError()
+ (+) Get HAL state machine or error values using HAL_SMBUS_GetState() or HAL_SMBUS_GetError()
+ (+) In case of transfer Error, HAL_SMBUS_ErrorCallback() function is executed and user can
+ add his own code by customization of function pointer HAL_SMBUS_ErrorCallback()
+ to check the Error Code using function HAL_SMBUS_GetError()
+
+ *** SMBUS HAL driver macros list ***
+ ==================================
+ [..]
+ Below the list of most used macros in SMBUS HAL driver.
+
+ (+) __HAL_SMBUS_ENABLE: Enable the SMBUS peripheral
+ (+) __HAL_SMBUS_DISABLE: Disable the SMBUS peripheral
+ (+) __HAL_SMBUS_GET_FLAG: Check whether the specified SMBUS flag is set or not
+ (+) __HAL_SMBUS_CLEAR_FLAG: Clear the specified SMBUS pending flag
+ (+) __HAL_SMBUS_ENABLE_IT: Enable the specified SMBUS interrupt
+ (+) __HAL_SMBUS_DISABLE_IT: Disable the specified SMBUS interrupt
+
+ [..]
+ (@) You can refer to the SMBUS HAL driver header file for more useful macros

+ * + Peripheral Control functions
+ * + Peripheral State functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### 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 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=0) 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()
+ [..]
+ The HAL drivers do not allow reaching all supported SPI frequencies in the different SPI
+ modes. Refer to the source code (stm32xxxx_hal_spi.c header) to get a summary of the
+ maximum SPI frequency that can be reached with a data size of 8 or 16 bits, depending on
+ the APBx peripheral clock frequency (fPCLK) used by the SPI instance.
+
+ [..]
+ Data buffer address alignment restriction:
+ (#) In case more than 1 byte is requested to be transferred, the HAL SPI uses 16-bit access for data buffer.
+ But there is no support for unaligned accesses on the Cortex-M0 processor.
+ So, if the user wants to transfer more than 1 byte, it shall ensure that 16-bit aligned address is used for:
+ (##) pData parameter in HAL_SPI_Transmit(), HAL_SPI_Transmit_IT(), HAL_SPI_Receive() and HAL_SPI_Receive_IT()
+ (##) pTxData and pRxData parameters in HAL_SPI_TransmitReceive() and HAL_SPI_TransmitReceive_IT()
+ (#) There is no such restriction when going through DMA by using HAL_SPI_Transmit_DMA(), HAL_SPI_Receive_DMA()
+ and HAL_SPI_TransmitReceive_DMA().

+ ##### TIMER Generic features #####
+ ==============================================================================
+ [..] The Timer features include:
+ (#) 16-bit up, down, up/down auto-reload counter.
+ (#) 16-bit programmable prescaler allowing dividing (also on the fly) the
+ counter clock frequency either by any factor between 1 and 65536.
+ (#) Up to 4 independent channels for:
+ (++) Input Capture
+ (++) Output Compare
+ (++) PWM generation (Edge and Center-aligned Mode)
+ (++) One-pulse mode output
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#) Initialize the TIM low level resources by implementing the following functions
+ depending from feature used :
+ (++) Time Base : HAL_TIM_Base_MspInit()
+ (++) Input Capture : HAL_TIM_IC_MspInit()
+ (++) Output Compare : HAL_TIM_OC_MspInit()
+ (++) PWM generation : HAL_TIM_PWM_MspInit()
+ (++) One-pulse mode output : HAL_TIM_OnePulse_MspInit()
+ (++) Encoder mode output : HAL_TIM_Encoder_MspInit()
+
+ (#) Initialize the TIM low level resources :
+ (##) Enable the TIM interface clock using __HAL_RCC_TIMx_CLK_ENABLE();
+ (##) TIM pins configuration
+ (+++) Enable the clock for the TIM GPIOs using the following function:
+ __HAL_RCC_GPIOx_CLK_ENABLE();
+ (+++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
+
+ (#) The external Clock can be configured, if needed (the default clock is the
+ 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
+ Initialization function of this driver:
+ (++) 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
+ Output Compare signal.
+ (++) 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.
+ (++) HAL_TIM_Encoder_Init: to use the Timer Encoder Interface.
+
+ (#) Activate the TIM peripheral using one of the start functions depending from the feature used:
+ (++) Time Base : HAL_TIM_Base_Start(), HAL_TIM_Base_Start_DMA(), HAL_TIM_Base_Start_IT()
+ (++) Input Capture : HAL_TIM_IC_Start(), HAL_TIM_IC_Start_DMA(), HAL_TIM_IC_Start_IT()
+ (++) Output Compare : HAL_TIM_OC_Start(), HAL_TIM_OC_Start_DMA(), HAL_TIM_OC_Start_IT()
+ (++) PWM generation : HAL_TIM_PWM_Start(), HAL_TIM_PWM_Start_DMA(), HAL_TIM_PWM_Start_IT()
+ (++) One-pulse mode output : HAL_TIM_OnePulse_Start(), HAL_TIM_OnePulse_Start_IT()
+ (++) Encoder mode output : HAL_TIM_Encoder_Start(), HAL_TIM_Encoder_Start_DMA(), HAL_TIM_Encoder_Start_IT().
+
+ (#) The DMA Burst is managed with the two following functions:
+ HAL_TIM_DMABurst_WriteStart()
+ HAL_TIM_DMABurst_ReadStart()

+ * @author MCD Application Team
+ * @brief TIM HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the Timer Extended peripheral:
+ * + Time Hall Sensor Interface Initialization
+ * + Time Hall Sensor Interface Start
+ * + Time Complementary signal bread and dead time configuration
+ * + Time Master and Slave synchronization configuration
+ * + Timer remapping capabilities configuration
+ @verbatim
+ ==============================================================================
+ ##### TIMER Extended features #####
+ ==============================================================================
+ [..]
+ The Timer Extended features include:
+ (#) Complementary outputs with programmable dead-time for :
+ (++) Output Compare
+ (++) PWM generation (Edge and Center-aligned Mode)
+ (++) One-pulse mode output
+ (#) Synchronization circuit to control the timer with external signals and to
+ interconnect several timers together.
+ (#) Break input to put the timer output signals in reset state or in a known state.
+ (#) Supports incremental (quadrature) encoder and hall-sensor circuitry for
+ positioning purposes
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (#) Initialize the TIM low level resources by implementing the following functions
+ depending from feature used :
+ (++) Complementary Output Compare : HAL_TIM_OC_MspInit()
+ (++) Complementary PWM generation : HAL_TIM_PWM_MspInit()
+ (++) Complementary One-pulse mode output : HAL_TIM_OnePulse_MspInit()
+ (++) Hall Sensor output : HAL_TIM_HallSensor_MspInit()
+
+ (#) Initialize the TIM low level resources :
+ (##) Enable the TIM interface clock using __HAL_RCC_TIMx_CLK_ENABLE();
+ (##) TIM pins configuration
+ (+++) Enable the clock for the TIM GPIOs using the following function:
+ __HAL_RCC_GPIOx_CLK_ENABLE();
+ (+++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
+
+ (#) The external Clock can be configured, if needed (the default clock is the
+ internal clock from the APBx), using the following function:
+ HAL_TIM_ConfigClockSource, the clock configuration should be done before

+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ This file must be copied to the application folder and modified as follows:
+ (#) Rename it to 'stm32f0xx_hal_timebase_rtc_alarm.c'
+ (#) Add this file and the RTC HAL drivers to your project and uncomment
+ HAL_RTC_MODULE_ENABLED define in stm32f0xx_hal_conf.h
+
+ [..]
+ (@) HAL RTC alarm and HAL RTC wakeup drivers canÂ’t be used with low power modes:
+ The wake up capability of the RTC may be intrusive in case of prior low power mode
+ configuration requiring different wake up sources.
+ Application/Example behavior is no more guaranteed
+ (@) The stm32f0xx_hal_timebase_tim use is recommended for the Applications/Examples
+ requiring low power modes

+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ This file must be copied to the application folder and modified as follows:
+ (#) Rename it to 'stm32f0xx_hal_timebase_rtc_wakeup.c'
+ (#) Add this file and the RTC HAL drivers to your project and uncomment
+ HAL_RTC_MODULE_ENABLED define in stm32f0xx_hal_conf.h
+
+ [..]
+ (@) HAL RTC alarm and HAL RTC wakeup drivers canÂ’t be used with low power modes:
+ The wake up capability of the RTC may be intrusive in case of prior low power mode
+ configuration requiring different wake up sources.
+ Application/Example behavior is no more guaranteed
+ (@) The stm32f0xx_hal_timebase_tim use is recommended for the Applications/Examples
+ requiring low power modes

+ @verbatim
+================================================================================
+ ##### TSC specific features #####
+================================================================================
+ [..]
+ (+) Proven and robust surface charge transfer acquisition principle
+
+ (+) Supports up to 3 capacitive sensing channels per group
+
+ (+) Capacitive sensing channels can be acquired in parallel offering a very good
+ response time
+
+ (+) Spread spectrum feature to improve system robustness in noisy environments
+
+ (+) Full hardware management of the charge transfer acquisition sequence
+
+ (+) Programmable charge transfer frequency
+
+ (+) Programmable sampling capacitor I/O pin
+
+ (+) Programmable channel I/O pin
+
+ (+) Programmable max count value to avoid long acquisition when a channel is faulty
+
+ (+) Dedicated end of acquisition and max count error flags with interrupt capability
+
+ (+) One sampling capacitor for up to 3 capacitive sensing channels to reduce the system
+ components
+ (+) Compatible with proximity, touchkey, linear and rotary touch sensor implementation
+
+ ##### How to use this driver #####
+================================================================================
+ [..]
+ (#) Enable the TSC interface clock using __HAL_RCC_TSC_CLK_ENABLE() macro.
+
+ (#) GPIO pins configuration
+ (++) Enable the clock for the TSC GPIOs using __HAL_RCC_GPIOx_CLK_ENABLE() macro.
+ (++) Configure the TSC pins used as sampling IOs in alternate function output Open-Drain mode,
+ and TSC pins used as channel/shield IOs in alternate function output Push-Pull mode
+ using HAL_GPIO_Init() function.
+ (++) Configure the alternate function on all the TSC pins using HAL_xxxx() function.
+
+ (#) Interrupts configuration
+ (++) Configure the NVIC (if the interrupt model is used) using HAL_xxx() function.
+
+ (#) TSC configuration
+ (++) Configure all TSC parameters and used TSC IOs using HAL_TSC_Init() function.
+
+ *** Acquisition sequence ***
+ ===================================
+ [..]
+ (+) Discharge all IOs using HAL_TSC_IODischarge() function.
+ (+) Wait a certain time allowing a good discharge of all capacitors. This delay depends
+ of the sampling capacitor and electrodes design.
+ (+) Select the channel IOs to be acquired using HAL_TSC_IOConfig() function.
+ (+) Launch the acquisition using either HAL_TSC_Start() or HAL_TSC_Start_IT() function.

+ * @brief UART HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the Universal Asynchronous Receiver Transmitter (UART) peripheral:
+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral Control functions
+ * + Peripheral State and Errors functions
+ *
+ @verbatim
+ ===============================================================================
+ ##### 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 as alternate function pull-up.
+ (++) 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.
+ (++) UART interrupts handling:
+ -@@- The specific UART interrupts (Transmission complete interrupt,
+ RXNE interrupt and Error Interrupts) are managed using the macros
+ __HAL_UART_ENABLE_IT() and __HAL_UART_DISABLE_IT() inside the transmit and receive processes.
+ (++) 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.

+ This subsection provides a set of functions allowing to manage the UART asynchronous
+ and Half duplex data transfers.
+
+ (#) There are two mode 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()

+ (++) 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_IT()
+ (++) HAL_UART_AbortTransmit_IT()

+ (++) 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.

+ ##### Initialization and Configuration functions #####
+ ==============================================================================
+ [..]
+ This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
+ in asynchronous mode.
+ (+) For the asynchronous mode the parameters below can be configured:
+ (++) Baud Rate
+ (++) Word Length (Fixed to 8-bits only for LIN mode)
+ (++) Stop Bit
+ (++) Parity
+ (++) Hardware flow control
+ (++) Receiver/transmitter modes
+ (++) Over Sampling Method
+ (++) One-Bit Sampling Method
+ (+) For the asynchronous mode, the following advanced features can be configured as well:
+ (++) TX and/or RX pin level inversion
+ (++) data logical level inversion
+ (++) RX and TX pins swap
+ (++) RX overrun detection disabling
+ (++) DMA disabling on RX error
+ (++) MSB first on communication line
+ (++) auto Baud rate detection
+ [..]
+ The HAL_LIN_Init() and HAL_RS485Ex_Init() APIs follows respectively the LIN and
+ the UART RS485 mode configuration procedures (details for the procedures are
+ available in reference manual).
+
+@endverbatim
+ * @{
+ */
+
+/*
+ Additional Table: 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.
+ According to device capability (support or not of 7-bit word length),
+ frame length is either defined by the M bit (8-bits or 9-bits)
+ or by the M1 and M0 bits (7-bit, 8-bit or 9-bit).
+ Possible UART frame formats are as listed in the following table:

+ [..] This subsection provides a set of functions allowing to manage the USART synchronous
+ data transfers.
+
+ [..] 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 APIs 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
+
+ (#) No-Blocking mode APIs with Interrupt are :
+ (++) 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()
+
+ (#) No-Blocking mode APIs with DMA are :
+ (++) HAL_USART_Transmit_DMA()in simplex mode
+ (++) 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_TxCpltCallback()
+ (++) HAL_USART_RxCpltCallback()
+ (++) HAL_USART_TxHalfCpltCallback()
+ (++) HAL_USART_RxHalfCpltCallback()
+ (++) 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 function
+ * + 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 over 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 informs when a WWDG reset has
+ occurred (check available with __HAL_RCC_GET_FLAG(RCC_FLAG_WWDGRST)).
+
+ (+) The WWDG downcounter input clock is derived from the APB clock divided
+ by a programmable prescaler.
+
+ (+) WWDG downcounter clock (Hz) = PCLK / (4096 * Prescaler)
+
+ (+) WWDG timeout (ms) = (1000 * (T[5;0] + 1)) / (WWDG downcounter clock)
+ where T[5;0] are the lowest 6 bits of downcounter.
+
+ (+) WWDG Counter refresh is allowed between the following limits :
+ (++) min time (ms) = (1000 * (T[5;0] - Window)) / (WWDG downcounter clock)
+ (++) max time (ms) = (1000 * (T[5;0] - 0x40)) / (WWDG downcounter clock)
+
+ (+) Min-max timeout value @48 MHz(PCLK): ~85,3us / ~5,46 ms
+
+ (+) The Early Wakeup Interrupt (EWI) can be used if specific safety
+ operations or data logging must be performed before the actual reset is
+ generated. When the downcounter reaches the value 0x40, an EWI interrupt
+ is generated and the corresponding interrupt service routine (ISR) can
+ be used to trigger specific actions (such as communications or data
+ logging), before resetting the device.
+ In some applications, the EWI interrupt can be used to manage a software
+ system check and/or system recovery/graceful degradation, without
+ generating a WWDG reset. In this case, the corresponding interrupt
+ service routine (ISR) should reload the WWDG counter to avoid the WWDG
+ reset, then trigger the required actions.
+ Note:When the EWI interrupt cannot be served, e.g. due to a system lock
+ in a higher priority task, the WWDG reset will eventually be generated.
+
+ (+) Debug mode : When the microcontroller enters debug mode (core halted),
+ the WWDG counter either continues to work normally or stops, depending
+ on DBG_WWDG_STOP configuration bit in DBG module, accessible through
+ __HAL_DBGMCU_FREEZE_WWDG() and __HAL_DBGMCU_UNFREEZE_WWDG() macros
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ (+) Enable WWDG APB1 clock using __HAL_RCC_WWDG_CLK_ENABLE().
+
+ (+) Set the WWDG prescaler, refresh window, counter value and Early Wakeup
+ Interrupt mode using using HAL_WWDG_Init() function.
+ This enables WWDG peripheral and the downcounter starts downcounting
+ from given counter value.
+ Init function can be called again to modify all watchdog parameters,
+ however if EWI mode has been set once, it can't be clear until next
+ reset.
+
+ (+) 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 window value already programmed.
+
+ (+) if Early Wakeup Interrupt mode is enable an interrupt is generated when
+ the counter reaches 0x40. User can add his own code in weak function
+ HAL_WWDG_EarlyWakeupCallback().
+
+ *** WWDG HAL driver macros list ***
+ ==================================
+ [..]
+ Below the list of most used macros in WWDG HAL driver.
+
+ (+) __HAL_WWDG_GET_IT_SOURCE: Check the selected WWDG's interrupt source.
+ (+) __HAL_WWDG_GET_FLAG: Get the selected WWDG's flag status.
+ (+) __HAL_WWDG_CLEAR_FLAG: Clear the WWDG's pending flags.
