Short timer IRQ

ONE
1

First happy new year to all of you!

Now back to reality:

I am using rtc.enableAlarm(RTCZero::MATCH_SS) to wakeup my program from deep sleep every minute. This is also the shortest timeout that I know that I can set.

Now I am looking for a way to receive a wakeup event every second or even better, every milli second.

Who knows?

I found a work around for the one second problem: MATCH_SS: a one second timer.

Still looking for a high speed IRQ to do some multiplexing. Who knows?
