AVRoxide Release 0.4.0
The latest version of my OS for ATmega AVRs, AVRoxide, is now available - with drivers for storage and graphics devices.
Subtle differences in interrupt handling on AVR microcontrollers
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.
Finally: AVRoxide - a working Rust runtime for ATmega4809
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.)
You Won’t Believe How to Make rustc Generate Working Optimised Code for ATmega4809
Until I discovered this trick, I couldn’t build working ATmega4809 Rust code with anything other than optimisation level 1…
