Finally getting back into some electronics after a long hiatus. Starting up with a little servo project that I'm hoping to run off of a QT PY SAMD21. I'd like to have the mechanism plugged in 24/7 in a low power state, wake using an interrupt, do its motor thing, then go back to sleep.
- I see that hardware interrupts are supported: viewtopic.php?f=19&p=856812
- And in this thread, I see that the SAMD21 can go pretty low but doesn't have the "deep sleep" of the ESP32-S2: viewtopic.php?p=916484&hilit=qt+py+samd21+sleep#p916484
Secondly and perhaps more strategically: what's the best way to create a 24/7 plugged-in device that is low power until needed? I assumed that my approach of "sleep + interrupt" was good, but I'm open to hearing something better!
Thanks in advance!
