“I looked at all the available rotary encoder sketches and none of them met my needs, so I have written my own, and here it is”. Well, I looked at all the ...

This library uses a PCF8575 to read the pulses of a rotary encoder. As a PCF8575 has 16 lines up to 8 decoders can be read over I2C. The PCF interrupt line can be used to detect changes in the ...

The difference between a full step or half step Rotary Encoder type is how the data signals of the two pins are generated. It depends on the mechanical construction of the notches and contacts inside ...

秋月電子通商で購入できる「LED付ロータリーエンコーダー(赤)ツマミ付セット」をESP32で読み取りたいと思っている。過去の2つの記事でポーリングで実装して、回転させた内容を読み取ることができた。今回、ポーリングの限界と割り込みの導入について ...
