Function Documentation

HAL_StatusTypeDef HAL_InitTick ( uint32_t TickPriority )

This function configures the RTC_WKUP as a time base source. The time source is configured to have 1ms time base with a dedicated Tick interrupt priority. Wakeup Time base = ((RTC_ASYNCH_PREDIV + 1) * (RTC_SYNCH_PREDIV + 1)) / RTC_CLOCK = 1ms Wakeup Time = WakeupTimebase * WakeUpCounter (0 + 1) = 1 ms.

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

Parameters

TickPriority Tick interrupt priority.

Return values

HAL status

Definition at line 120 of file stm32f7xx_hal_timebase_rtc_wakeup_template.c.

void HAL_ResumeTick ( void )

Resume Tick increment.

Note: Enable the tick increment by Enabling RTC_WKUP interrupt.

Parameters

None

Return values

None

Definition at line 255 of file stm32f7xx_hal_timebase_rtc_wakeup_template.c.

void HAL_RTCEx_WakeUpTimerEventCallback ( RTC_HandleTypeDef * hrtc )

Wake Up Timer Event Callback in non blocking mode.

Note: This function is called when RTC_WKUP interrupt took place, inside RTC_WKUP_IRQHandler(). It makes a direct call to HAL_IncTick() to increment a global variable "uwTick" used as application time base.

Parameters
