Today I successfully got #Rust code working for a #RaspberryPi #PicoW board! Not bad. All credit goes to the toolchains and projects... my efforts here are purely exploratory / discovery. My current status is I got some Pico / Pico W sample code working and then merged some samples together to form a foundation I'll build more code on top of. The merged code achieves:
The real TL;DR is: The embassy project seems to be the best starting point for Rust on a Pico W. (Not a Pico 2, this is an older RP2040 board.)
The long version is: https://yvan.seth.id.au/rusty-pico-w.html
