micropython-rotary
A MicroPython driver for reading rotary encoders with hardware interrupt support and effective debouncing.
What is micropython-rotary?
micropython-rotary is a MicroPython library for interfacing with rotary encoders on embedded development boards. It reads encoder rotations using hardware interrupts and implements a debouncing state machine to provide accurate and reliable counts. The driver supports various range modes, configurable increments, and platform-specific optimizations for boards like ESP32, Raspberry Pi Pico, and Pyboard.
Embedded developers and hobbyists working with MicroPython on devices like ESP32, Raspberry Pi Pico, or Pyboard who need to integrate rotary encoders for input control in projects such as dials, menus, or parameter adjustment interfaces.
Developers choose this library for its robust debouncing implementation, interrupt-driven efficiency, and cross-platform support. It offers a reliable, battle-tested solution adapted from Ben Buxton's proven algorithm, reducing software glitches and ensuring accurate encoder readings in resource-constrained embedded environments.
