EncoderTool: using rotary encoders on Teensy ARM boards #Teensy @luni_64
EncoderTool is a software library to manage and read out rotary encoders with Teensy ARM boards. It has an MIT license.
Key features
Supports directly connected and multiplexed encoders
Supports all common types of encoders, i.e., full (no detents, 4 counts per period), half (two detents and two counts per period) and quarter (1 detent and one count per period) and some variants of those.
A callback mechanism allows for easy event based menu systems. Callbacks use std::function and can call non static member functions.
Fully bounce free without additional hardware
Provides hard and cyclic count limits
Supports and debounces encoder push buttons. Callback for notification of button events available
Currently 74165, 4067 and 4051 based multiplexers are supported but the class structure allows for easy extension to any other multiplexer.
Schematics and Eagle files for multiplexed encoders available in the Extras folder

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
