==============================================================================
##### 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 @ref HAL_TIM_RegisterCallback() to register a callback.
@ref HAL_TIM_RegisterCallback() takes as parameters the HAL peripheral handle,
the Callback ID and a pointer to the user callback function.
[..]
Use function @ref HAL_TIM_UnRegisterCallback() to reset a callback to the default
weak function.
@ref HAL_TIM_UnRegisterCallback takes as parameters the HAL peripheral handle,
and the Callback ID.
[..]
These functions allow to register/unregister following callbacks:
(+) Base_MspInitCallback : TIM Base Msp Init Callback.
(+) Base_MspDeInitCallback : TIM Base Msp DeInit Callback.
(+) IC_MspInitCallback : TIM IC Msp Init Callback.
(+) IC_MspDeInitCallback : TIM IC Msp DeInit Callback.
(+) OC_MspInitCallback : TIM OC Msp Init Callback.
(+) OC_MspDeInitCallback : TIM OC Msp DeInit Callback.
(+) PWM_MspInitCallback : TIM PWM Msp Init Callback.
(+) PWM_MspDeInitCallback : TIM PWM Msp DeInit Callback.
(+) OnePulse_MspInitCallback : TIM One Pulse Msp Init Callback.
(+) OnePulse_MspDeInitCallback : TIM One Pulse Msp DeInit Callback.
(+) Encoder_MspInitCallback : TIM Encoder Msp Init Callback.
(+) Encoder_MspDeInitCallback : TIM Encoder Msp DeInit Callback.
(+) HallSensor_MspInitCallback : TIM Hall Sensor Msp Init Callback.
(+) HallSensor_MspDeInitCallback : TIM Hall Sensor 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.
(+) CommutationCallb

温馨提示
输入捕获说的通俗一点就是用计数器(定时器)来记录某一个脉冲高电平的时间,或者我们只捕获脉冲的上升沿或者下降沿,这具体要根据具体事例进行分析。 它的基本工作过程就是先捕捉一次脉冲上升沿,然后计数器开始计时,等待着捕捉到脉冲下降沿,等到捕捉到下降沿的时候,计数器停止计数,计算计数器中的数值,这个数值就是高电平所持续的时间,然后再重现开始下一轮的捕捉。 此程序输入捕获来实现计算某一个脉冲的低电平持续时间
