Compiling

To compile the program, the thumbv6m-none-eabi toolchain is required

rustup target add thumbv6m-none-eabi

To convert the ELF into a UF2 file, elf2uf2-rs is required

cargo install elf2uf2-rs

Once these are installed, plug the pico in while holding the BOOTSEL button and run cargo run

To get the executable instead, run cargo build then elf2uf2-rs target/thumbv6m-none-eabi/debug/morse_code
