  ==============================================================================
                      ##### 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()
