group TimeBase_TIM_Exported_Functions

This group gathers functions for the HAL timebase based on a timer instance.

Functions

hal_status_t HAL_InitTick ( hal_tick_freq_t tick_freq , uint32_t tick_priority )

This function configures the TIMx as a time base source. The time source is configured to have a 1 ms time base with a dedicated tick interrupt priority.

Note

This function is called automatically at the beginning of the program after reset by HAL_Init() or when the clock is configured by HAL_RCC_ClockConfig().

Parameters :

tick_priority – Tick interrupt priority.

Return values :

• HAL_OK – HAL TIM time base correctly configured.

• HAL_ERROR – Error occurred during HAL TIM time base configuration.

void HAL_SuspendTick ( void )

Suspend tick increment.

Note

Disable the tick increment by disabling the TIMx update interrupt.

void HAL_ResumeTick ( void )

Resume tick increment.

Note

Enable the tick increment by enabling the TIMx update interrupt.

void TimeBase_TIM_UpdateCallback ( hal_tim_handle_t * htim )

Timer update interrupt callback.

Note

Depending on the configuration, it can be registered as a callback or used directly.
