• Set up a Rust environment for embedded development.
• Run Blinky on RaspberryPi Pico.
• Control a SPI device from the Pico.

• Evaluate how the Rust ecosystem compares against traditional embedded development tools.
• Evaluate Just against tradtional Make.
• Evaluate DevEnv as depencency management.

1. Make sure that you have libudev-dev, eg. sudo apt install libudev-dev.
2. Install DevEnv so that you have a Nix package management infrastructure. See notes.

Run devenv shell to switch into the development environment where all the needed tools and dependencies are installed, sort of like with Python virtual environments.

Run just to see the available project-specific commands.

Run exit to exit the development environment.

Have not found out how to actually make devenv control to the rust eco system, so not using the devenv setup for rust. Had to do this instead:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
sudo apt install libudev-dev
cargo install elf2uf2-rs flip-link --locked

On NixOS, do nix-shell -p pkg-config udev instead of installing libudev, and then run cargo install flip-link & elf2uf2-rs --locked.

Finally do

rustup target add thumbv6m-none-eabi

For Just:

wget -qO - 'https://proget.makedeb.org/debian-feeds/prebuilt-mpr.pub' | gpg --dearmor | sudo tee /usr/share/keyrings/prebuilt-mpr-archive-keyring.gpg 1> /dev/null
echo "deb [arch=all,$(dpkg --print-architecture) signed-by=/usr/share/keyrings/prebuilt-mpr-archive-keyring.gpg] https://proget.makedeb.org prebuilt-mpr $(lsb_release -cs)" | sudo tee /etc/apt/sources.list.d/prebuilt-mpr.list
sudo apt update
sudo apt install just
