A developer launched an open-source eInk bike computer project called OpenTrailPaper. Notably, the project also includes an AI-assisted implementation of the ANT wireless sensor protocol for ESP32, discovered through undocumented register exploration.
Background
E-ink displays are popular for bike computers due to their low power consumption and sunlight readability. The ANT+ protocol is widely used in cycling sensors but lacks official open-source ESP32 support.
