These vintage push-button light switches look extremely satisfying to use. If I had them in my home there would be a little problem for the people I live with. The lights would constantly be ...

How to substantially reduce encoder cost while gaining functionality with 44-Turn multi-turn rotary position sensors—retaining count and position during power loss.

rot_btn_i2c is a ESP32 IDF component to read and decode a mechanical rotary encoder and up to 14 buttons connected to the ESP32 by a TCA9555 port expander. It uses the RiskV ULP of the ESP32-S3 and ...

Abstract: The paper proposes an offline self-calibration scheme about establishing a signal flow network(SNF) to calibrate capacitive rotary encoder. This scheme proposes to simulate the flow of ...
