The latest version of my OS for ATmega AVRs, AVRoxide, is now available - with drivers for storage and graphics devices.

As I’ve written before, more than a year ago Rust on AVR went into the weeds because of bugs in LLVM.

I made a workaround, but it was far from ideal - and if it’s been frustrating for me, I’m sure it’s been a complete barrier to many even getting started with AVR on Rust.

Anyway, all that has now changed, thanks to Patryk27, who has managed to merge the necessary patches into the Rust master, so now the regular Rust nightly toolchain builds for AVR again. Hurrah, and the inaugural (and possibly ultimate) ‘Hero of the Week’ award goes to Patryk :-).

A new release of AVRoxide, my OS for ATmega AVRs, is out - now with multithreading!

There are subtle differences between the way interrupts are handled on different AVR microcontrollers. I didn’t see this written in plain English anywhere, so I’ll have a go.

It’s been quite a few months' work, with many challenges along the way - but finally I’m pleased to announce that I have a working runtime for writing applications in Rust for the ATmega4809 microcontroller (and thus also for the Arduino Nano Every.)
