Hi,
In MQX4.0.1, I use the following code to create a RTC alarm. But when it enter the rtc_alarm_interrupt, the RTC_SR is always 0x10 which seems wrong. Because it is an alarm interrupt, it should be 0x04. Please advice.
Thank you.
void rtc_alarm_interrupt(pointer rtc_registers_ptr)
{
uint_32 ui32Status = 0;
ui32State = _rtc_get_status();
if(ui32State & RTC_RTCISR_ALM)
{
}
ui32Status = RTC_SR;
_rtc_clear_requests(ui32State);
}
void main()
{
DATE_STRUCT alarm_time_rtc;
TIME_STRUCT alarm_time_mqx;
if(MQX_OK != _rtc_int_install(rtc_alarm_interrupt))
{
_task_block();;
}
_rtc_clear_requests(RTC_RTCISR_ALM);
if(0 == _rtc_int_enable(TRUE, RTC_RTCIENR_ALM))
{
_task_block();
}
_rtc_set_alarm_mqxd(&alarm_time_rtc);
_time_to_date(&alarm_time_mqx, &alarm_time_rtc);
alarm_time_rtc.SECOND += 30;
for(;;);
}
