Posted on August 01, 2015 at 18:18*Bug: HAL_RTC weakup does not interrupt
*Reason:
The library
stm32f4xx_hal_rtc_ex.h missing to clear the interrupt flag before enabling the interrupt
*Solution:
Manually add this line (clear the interrupt flag):
/* Clear the Flags in the RTC_ISR register */
RTC->ISR = (uint32_t)((uint32_t)(~((RTC_FLAG_WUTF | RTC_ISR_INIT)& 0x0000FFFF) | (uint32_t)(RTC->ISR & RTC_ISR_INIT)));
before the /* RTC WakeUpTimer Interrupt Configuration: EXTI configuration */ line
*ST please fix file:
@file stm32f4xx_hal_rtc_ex.c
* @author MCD Application Team
* @version V1.3.2
