1 year ago @dseymore Sorry we don't have a plan to implement RTC based dormant function. Instead of this function you can use delay(msec) function to make the board sleep mode.
you can find the detailed information in the below link. https://github.com/kaluma-project/kaluma/issues/412
I hit a snag with my project because of a naive expectation was that RTC would continue running while dormant. I noticed that there is an example on pico-extras/.../sleep.c that shows the ability for the device to maintain RTC with a time based interrupt.
I'd still like to preserve the wake on pin semantics but provide a new sleep operation on the RP2 module.
Is this possibly already under development? If not I think I could proof of concept it in a couple weekends. Or is there an alternative approach that would be suggested?
