◆ HAL_RTCEx_DeactivateWakeUpTimer()

HAL_StatusTypeDef HAL_RTCEx_DeactivateWakeUpTimer ( RTC_HandleTypeDef * hrtc )

#include <stm32f4xx_hal_rtc_ex.h>

Deactivates wakeup timer counter.

Parameters

hrtc	pointer to a RTC_HandleTypeDef structure that contains the configuration information for RTC.

Return values

◆ HAL_RTCEx_GetWakeUpTimer()

uint32_t HAL_RTCEx_GetWakeUpTimer ( RTC_HandleTypeDef * hrtc )

#include <stm32f4xx_hal_rtc_ex.h>

Gets wakeup timer counter.

Parameters

hrtc	pointer to a RTC_HandleTypeDef structure that contains the configuration information for RTC.

Return values

Counter value

◆ HAL_RTCEx_WakeUpTimerIRQHandler()

void HAL_RTCEx_WakeUpTimerIRQHandler ( RTC_HandleTypeDef * hrtc )

#include <stm32f4xx_hal_rtc_ex.h>

Handles Wakeup Timer interrupt request.

Note: Unlike alarm interrupt line (shared by Alarms A and B) or tamper interrupt line (shared by timestamp and tampers) wakeup timer interrupt line is exclusive to the wakeup timer. There is no need in this case to check on the interrupt enable status via __HAL_RTC_WAKEUPTIMER_GET_IT_SOURCE().
