Ok, now I've dug myself deeper. ![:)]( "Smile")
Thanks to the pointers above, I could easily extend the pico_sleep code so that the Pico2 would wake up on GPIO activity. I set up IRQs for 24 pins, and it would exit Dormant state for any of them. The problem was that the power consumption in dormant state was a bit high - around 3mA or so.
I switched to the powman approach and got between 0.65 and 0.85 mA of current in the power down stage which is MUCH better. The problem with this approach is that it seems I can only actively monitor 4 GPIOs at a time. The wakeup source is specified by an index instead of a bitfield.
Is there any way to get around this?
