Rotary Encoder Experimenter's Dev Board
UPDATE: new revision 9-29-24 posted. Lower parts count, more reliable software debouncing for the encoder, and improved ground plane--please see this blog post for details:
https://audiodiwhy.blogspot.com/2024/11/rotary-encoder-dev-board-improving.html
================
I want to learn more about creating user interfaces for embedded system projects, so I made a board that accommodate A Raspberry Pi Pico development board, a single rotary encoder, some GPIOs brought out to wirepads, 4 LED's, and an I2C 1306 based OLED.
Please see this blog post for details:
https://audiodiwhy.blogspot.com/2024/08/debouncing-rotary-encoder-revisted.html
The project uses an extremely useful debounce library from Marco Pinteric, further modified by Christer Janson.
I have ported the polling class to RP2040. There will be an ongoing series of projects based on this algorithm.
You can get the RP2040 port from GitHub:
