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