Rust RP2040 USB Device Example

This is a worked example of implementing a USB device on the RP2040 microcontroller, in Rust. It is designed to be easy to read, as a reference for how to get USB working.

More details in the comment at the top of src/main.rs.

Running this code

As of this writing (2022-04-08), you will need my fixed version of elf2uf2-rs to run this binary. This program is available from:

https://github.com/cbiffle/elf2uf2-rs/tree/fix-range-check

Checkout that code and run, in that directory,

cargo install --path .

Now, back in this directory, cargo run --release ought to work.
