I’m developing a thermostat for my house gas stove. Version 1 was quite simple, but version 2 uses the M5Stack dial for a user interface and communicates via Grove-WIO-E5-HF’s with the stove to turn it on & off. It’s at https://github.com/vashjuan/M5DialThermo if the code helps anyone.
My question is simply whether the Grove-Wio-E5 exposes DIO0/DIO1 pins? If so one could avoid all the polling I’m currently doing and move to a hardware interrupt scheme that I presume would be much lower power.
Thanks!
