STM32F030满足条件后配置RTC唤醒
void RTC_AlarmConfig(void)
{
RTC_
timeTypeDef sTime = {0};
RTC_AlarmTypeDef sAlarm = {0};
/* Get current time */
HAL_RTC_GetTime( hrtc, sTime, RTC_FORMAT_BIN);
sAlarm.AlarmTime.Hours = sTime.Hours;
sAlarm.AlarmTime.Minutes = sTime.Minutes;
sAlarm.AlarmTime.Seconds = sTime.Seconds + 5;
sAlarm.AlarmTime.SubSeconds = 0;
sAlarm.AlarmTime.DayLightSaving = RTC_DAYLIGHTSAVING_NONE;
sAlarm.AlarmTime.StoreOperation = RTC_STOREOPERATION_RESET;
sAlarm.AlarmMask = RTC_ALARMMASK_DATEWEEKDAY|RTC_ALARMMASK_HOURS
|RTC_ALARMMASK_MINUTES;//|RTC_ALARMMASK_SECONDS
sAlarm.AlarmSubSecondMask = RTC_ALARMSUBSECONDMASK_ALL;
sAlarm.AlarmDateWeekDaySel = RTC_ALARMDATEWEEKDAYSEL_DATE;
sAlarm.AlarmDateWeekDay = 1;
sAlarm.Alarm = RTC_ALARM_A;
if (HAL_RTC_SetAlarm_IT( hrtc, sAlarm, RTC_FORMAT_BIN) != HAL_OK)
{
Error_Handler();
}
}
然后调用HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI)进入STOP模式正常，但是RTC唤醒后第二次
调用HAL_PWR_EnterSTOPMode函数发现MCU没有进入STOP模式，这个是什么原因啊？
