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