After moving ESP32 firmware from ESP-IDF to Rust + embassy, a developer dissatisfied with existing UI options built twine, an LVGL-style declarative Rust graphics library for embedded displays, written largely with Claude Opus 5.5 and dual-licensed open source.
- Demo on a CYD board: live aircraft radar fed by a Raspberry Pi ADS-B receiver
- Considerable time spent (with Claude) optimizing animations and scrolling for smooth on-device performance
- Repo includes an llms.txt so coding agents can integrate with the API without reading the codebase
- API and internals still maturing; author plans ongoing maintenance
