Copi

An easier way to control Raspberry Pi Pico.

Extend IO for smart devices (Android/macOS/Windows/Linux) or enhance computing for Pico.

Build

Dependencies:

• Rust (Cargo)
• picotool (only for elf to uf2)

Add Pico2 target support

rustup target add thumbv8m.main-none-eabihf

Build Pico2 firmware

./build-firmware.sh

Output binary: firmware-output/copi-firmware-pico2.uf2

(Will use nightly to compile Pico2 firmware because the feature #![feature(generic_arg_infer)] is required)

Build copi-cli

cargo build --bin copi

Output executable:

target/debug/copi

Usage

$ target/debug/copi -h

Usage: copi [COMMAND]

Commands:
  list   List all connected boot pico devices
  flash  Flash copi firmware to the pico device
  help   Print this message or the help of the given subcommand(s)

Options:
  -h, --help     Print help
  -V, --version  Print version

Flash firmware to a Pico2

Hold the Pico2 BOOT button while connecting to the PC

List all connected boot pico devices

$ target/debug/copi list

Note the Pico2 mount location, e.g. /Volumes/RP2350 (macOS) or F: (Windows)

Flash copi firmware to the pico device

$ target/debug/copi flash /Volumes/RP2350

or

$ target/debug/copi flash F:

Run Copi

target/debug/copi
