Do you have any tutorials for this? I'm an embedded newbie and all the things I've seen required more knowledge than I have to either get to hello world or move an iota past it.
For AVR specifically, no. The Embedded Book [0] (which uses the ARM-based Discovery board) is a great introduction.
I can envision a future where clean abstractions are written that can provide an Arduino-like experience in Rust, but we are still a long way from there.
You are making me want to write some Rust AVR tutorials. Once we get the latest compiler building AVR code again, that will be my next focus.
I can really recommend getting a micro:bit board and following the discovery book [1].
There are a few other books in the embedded Rust bookshelf [2].
Otherwise, I wrote a bunch of sensor drivers and simple examples for several boards: [3]
