Bounce-Free Rotary Encoder Library
+Standard or Multiplexed Wiring
+Push Button Support
+Callback System



Supports



Board Compatibility


  • PJRC Teensy (Teensy-LC, Teensy 3.x, Teensy 4.x, MicroMod)

  • SAMD (SEEED XIAO, Nano33 ...)

  • 8bit Arduino AVR (UNO, Nano, Mega...)

  • ESP32

  • Fallback solution for other boards (using slow digitalRead/Write)


Features

  • Fully bounce free readout without additional hardware

  • Provides hard and cyclic count limits

  • Supports and debounces encoder push buttons

  • Modern callback system for event driven applications

  • Encoders can be connected directly (A / B / Btn connected to pins)

  • Encoder connection using various multiplexers (up to 32 encoders on only 4 control pins)

  • Schematics and Gerbers available for multiplexed encoder boards (Eagle/KiCad).
