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