cardputer-buddy

What problem does it solve?

Iterating on the Cardputer-Adv MicroPython “Cardputer Buddy” app bundle is slow when you have to re-flash for every small change, so developers need a faster workflow to add new apps, push updates, and debug what the device is doing over serial logs.

Core Features & Use Cases

• Add apps via a local buddy/device/apps workflow: Create or adapt an app module (e.g., based on the provided hello and snake examples) so it appears in the device launcher menu without rebuilding the whole payload.
• Push single-file changes: Upload only the modified .py (or a small subset) over USB-serial instead of performing full device re-flashing.
• Debug with device serial logs and one-shot commands: Tail serial output and run REPL one-liners to inspect the device filesystem and verify behavior after pushing changes.
• Best fit use cases: Following up after initial /maker-setup, adding a new app, updating Claude Buddy/MicroPython payload behavior, and iterating on BLE/UI/state/protocol integration.

Quick Start

Ask Claude Code to help you push a single changed app file to your already-provisioned Cardputer over USB-serial and verify the result by tailing the device logs.
