# Raspberry Pi Pico 2 - with Rust!
You will need nix with flakes enabled. Then:
# Setup
```shell_session
$ direnv allow # setup rustup and picotool
$ rustup show # install rustc, cargo, and the pico 2 toolchain
# plug in your pico 2 while holding the BOOTSEL button
$ cargo run --release
# this will probably fail the first and you will need to install whatever is missing with rustup
# then try again
```
1. Get `rustup` and `picotool` by running `direnv allow` (or however you like)
2. Install Rust components via `rustup` by running `rustup show`
Have fun!
# Flashing
Hold your Pi Pico 2's `BOOTSEL` button while plugging it in to your machine.
Then run `cargo run --release`.
To use the RISC-V target, run
`cargo run --release --target riscv32imac-unknown-none-elf`.
