RTC alarm interrupt while loop

Question

My problem is that when the rtc alarm is activated, it prints the message that is in the interrupt every 10 seconds, but it stops printing the messages that are in the while loop of the main.

I am using platformio and vs code to program the stm32f103rct6 microcontroller.

main.c

int main(void)
{
HAL_Init();
SystemClock_Config();
HardwareInit();
while (1)
{
HAL_RTC_GetDate(&hrtc, &sDate, RTC_FORMAT_BIN);
myprintf("Date: %02d-%02d-%02d\\n", sDate.Date, sDate.Month, 2000 + sDate.Year);

        HAL_RTC_GetTime(&hrtc, &sTime, RTC_FORMAT_BIN);
        myprintf("Time: %02d:%02d:%02d\n", sTime.Hours, sTime.Minutes, sTime.Seconds);
    
        HAL_RTC_GetAlarm(&hrtc, &sAlarm, RTC_ALARM_A, FORMAT_BIN);
        myprintf("Alarm: %02d:%02d:%02d\n", sAlarm.AlarmTime.Hours, sAlarm.AlarmTime.Minutes, sAlarm.AlarmTime.Seconds);
    
    }

}

stm32f1xx_it.c

void RTC_Alarm_IRQHandler(void)
{
    if (__HAL_RTC_ALARM_GET_FLAG(&hrtc, RTC_IT_ALRA) != RESET)
    {
        myprintf("Alarm match\\n");
        HAL_RTC_GetAlarm(&hrtc, &sAlarm, RTC_ALARM_A, FORMAT_BIN);
        sAlarm.AlarmTime.Seconds = sAlarm.AlarmTime.Seconds + 10;
        HAL_RTC_SetAlarm_IT(&hrtc, &sAlarm, FORMAT_BIN);
        __HAL_RTC_ALARM_CLEAR_FLAG(&hrtc, RTC_IT_ALRA);
    }
}

RTC_Init

void RTC_Init(void)
{
    __HAL_RCC_RTC_ENABLE();

    hrtc.Instance = RTC;
    hrtc.Init.AsynchPrediv = RTC_AUTO_1_SECOND;
    hrtc.Init.OutPut = RTC_OUTPUTSOURCE_ALARM;
    if (HAL_RTC_Init(&hrtc) != HAL_OK)
    {
        Error_Handler();
    }

    sTime.Hours = 0x13;
    sTime.Minutes = 0x30;
    sTime.Seconds = 0x0;
    if (HAL_RTC_SetTime(&hrtc, &sTime, RTC_FORMAT_BCD) != HAL_OK)
    {
        Error_Handler();
    }

    sDate.WeekDay = RTC_WEEKDAY_WEDNESDAY;
    sDate.Month = RTC_MONTH_NOVEMBER;
    sDate.Date = 0x29;
    sDate.Year = 0x23;
    if (HAL_RTC_SetDate(&hrtc, &sDate, RTC_FORMAT_BCD) != HAL_OK)
    {
        Error_Handler();
    }

    sAlarm.Alarm = RTC_ALARM_A;
    sAlarm.AlarmTime.Hours = sTime.Hours;
    sAlarm.AlarmTime.Minutes = sTime.Minutes;
    sAlarm.AlarmTime.Seconds = sTime.Seconds + 0x10;
    if (HAL_RTC_SetAlarm_IT(&hrtc, &sAlarm, RTC_FORMAT_BCD) != HAL_OK)
    {
        Error_Handler();
    }

    HAL_NVIC_SetPriority(RTC_Alarm_IRQn, 0, 0);
    HAL_NVIC_EnableIRQ(RTC_Alarm_IRQn);

    __HAL_RTC_ALARM_ENABLE_IT(&hrtc, RTC_IT_ALRA);
    __HAL_RTC_ALARM_CLEAR_FLAG(&hrtc, RTC_IT_ALRA);
}

I have tried clearing the flag and what I expect is that it will show me the message of the RTC alarm interruption but then follow the normal course until the new alarm.

Answer 1

I found the problem, by using the macro __HAL_RTC_ALARM_GET_FLAG and not using the usual function HAL_RTC_AlarmIRQHandler(&hrtc) to execute the callback function, I was missing the following line of code that is inside the previous function __HAL_RTC_ALARM_EXTI_CLEAR_FLAG().
