Catch RTC Alarm Interrupt

I would like to use the RTC to set an alarm and then catch the event when it goes off.

I know how to set the time and the alarm. Also found instructions on how to use the Alarm to wake up from a power sleep.

Is it possible to catch the interrupt and process it as a normal interrupt?

I’ve looked everywhere I can think of for instructions or an example, without success.


@ Duncan -

RTC doesn’t support this event. You can use Register class to check RTC Alarm register, poll and raise by yourself, but not exactly what you wanted.

Or you can create a class that checks the system clock (or RTC ) on a seperate thread and create your own event once it is greater than the alarm time.

@ Dat and hagster

Thanks for confirming it can’t be done directly.

I figure out something using the timer class.
