##### 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 __TIMx_CLK_ENABLE();
(##) TIM pins configuration
(+++) Enable the clock for the TIM GPIOs using the following function:
__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()
