 ### [`ravedude`](./ravedude) [![crates.io page](https://img.shields.io/crates/v/ravedude.svg)](https://crates.io/crates/ravedude)
 `ravedude` is a utility for seamlessly integrating avrdude and a serial console into the cargo workflow.  With a bit of configuration (check its [README](./ravedude/README.md)!) you can then upload your code to your board and view its output over the serial console by just using `cargo run` as you would normally.
