Cardputer Buddy

anthropics/claude-plugins-officialOfficial

Once you've flashed your M5Stack Cardputer with the Buddy firmware, you'll want this for everything that comes after. It gives you scripts to push individual Python files over USB serial, tail device logs, and fire off one-shot REPL commands without reflashing the whole device. The main use case is iterating on the app bundle (Claude Buddy BLE client, Snake, or your own additions). Drop a new .py into the apps folder, run install_apps.py or push.py, and it shows up in the launcher menu on next boot. Beats the write-flash-pray cycle when you're tweaking a game or adding hardware integrations.

Install

$ npx -y skills add anthropics/claude-plugins-official --skill cardputer-buddy --agent claude-code

Installs into .claude/skills of the current project.

Files

Cardputer Buddy app bundle

The buddy/ directory in the local build-with-claude clone is the MicroPython payload that m5-onboard installs onto /flash/. Work inside that clone.

Device layout

/flash/
├── main.py              launcher menu (replaces UIFlow's boot flow)
├── buddy_*.py           shared libs (BLE, UI, state, protocol, chars)
├── burst_frames.py      sprite frames
└── apps/
    ├── claude_buddy.py  BLE client → Claude Desktop's Hardware Buddy
    ├── hello_cardputer.py
    └── snake.py

main.py scans /flash/apps/ at boot and lists every .py as a menu entry. Drop a file into buddy/device/apps/, push it, and it appears on next boot.

Adding an app

Crib from buddy/device/apps/hello_cardputer.py — smallest example of keyboard polling, font, and exit conventions. Then push without re-flashing:

python3 onboard/scripts/install_apps.py --port <PORT> --src buddy

<PORT> is whatever detect.py reported last run (e.g. /dev/cu.usbmodem1101, /dev/ttyACM0, COM3).

Dev loop tooling (buddy/scripts/)

# Push a subset of files over USB-serial
python3 buddy/scripts/push.py --port <PORT> --files apps/snake.py
