“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 ...

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、1msec間隔でポーリングして、AとBの値を監視して、グラフにしてみる実験。 理想では、「右回り (CW): 00 → 10 → 11 → 01 → 00」、「左回り (CCW): 00 → 01 → 11 → 10 → 00 ...

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 ...

There’s something to be said for the feel of controls. Whether it’s the satisfying snap of a high-quality switch or the buttery touch of the pots on an expensive amplifier, the tactile experience of ...

As you may have noticed, I’ve been working with an STM32 ARM CPU using Mbed. There was a time when Mbed was pretty simple, but a lot has changed since it has morphed into Mbed OS. Unfortunately, that ...

This file type includes high resolution graphics and schematics when applicable. Rotary encoders track motor shaft movement for myriad pieces of industrial equipment and commercial devices. For ...
