What would be the best starting point for writing a bare metal app for the Wio Terminal?
The ArduPy repo (https://github.com/Seeed-Studio/ArduPy/tree/master/ports/samd) looks like it could be an option, but I was hoping to maybe get a more minimal repo, with a “Blinky” kind of example app.
I don’t know what you mean, but the Arduino code itself is bare code.
We just merged support for the Wio-terminal into the samd embedded-Rust HAL, so you can write bare-metal Rust that runs on the Wio Terminal now.
Buttons / screen / USB works, and I’m working on getting the WiFi working next.
