Posted on March 31, 2015 at 17:08Hello,
I am trying to read the RTC time after setting it up. I am experiencing weird behavior.
I am using the STM32L0 discovery board.
I am using the new HAL libraries and the RTC alarm example.
I am using internal LSI and set the prescaler accordingly, per an app note.
I am using IAR
The alarm is working all the time, I can see the interrupt fire at the end of a minute delay, so I know the clock is actually working
However, I am trying to periodically read the current time using the following code:
//get time
if(HAL_RTC_GetTime(&RtcHandle,¤ttimestructure,FORMAT_BIN)==HAL_OK)
{
sprintf((char *) statusline,''%2d:%2d:%2d'',currenttimestructure.Hours,currenttimestructure.Minutes,currenttimestructure.Seconds);
}
else
{
sprintf((char *) statusline,''error'');
}
HAL_Delay(5000);
The problem:
if I set a breakpoint in the code, I see the RTC_TR update and the time is updated on the epd display
If I remove the breakpoint, the currenttime structure is never updated.
Thanks,
Ashraf
