ravedude

ravedude is a CLI utility to make Rust development for AVR microcontrollers super smooth. It's a wrapper around avrdude and provides easy access to the target's serial console, similar to the Arduino IDE.

ravedude is meant to be used as a cargo "runner". This allows you to just use cargo run for building, deploying, and running your AVR code!

Installation

On Linux systems, you'll need pkg-config and libudev development files installed:

• Archlinux: pacman -S systemd pkgconf
• Ubuntu/Debian: apt install libudev-dev pkg-config
• Fedora: dnf install systemd-devel pkgconf-pkg-config

Next, install the latest version from crates.io with the following command:

cargo install ravedude

Now you need to add ravedude to your project. For example in a project for Arduino Uno, place the following into your .cargo/config.toml (not in Cargo.toml):

[target.'cfg(target_arch = "avr")']
runner = "ravedude uno --open-console --baudrate 57600"

And that's all, now just call cargo run and watch it do its magic:

avr-hal/examples/arduino-uno on ravedude via v1.51.0-nightly 
❯ cargo run --bin uno-i2cdetect
   Compiling arduino-uno-examples v0.0.0 (avr-hal/examples/arduino-uno)
