This library uses a PCF8575 to read the pulses of a rotary encoder. As a PCF8575 has 16 lines up to 5 decoders with a switch can be read over I2C. The PCF interrupt line can be used to detect changes ...

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 ...

If you’ve ever spent time in a modern BMW, you’ve probably fussed about with the goofy iDrive controller. It’s a rotary knobbery slidery thing that just never really feels that good to use. [Garage ...

In robotics, movements must be precise and well-controlled. As robots are asked to do more as industry becomes more familiar with the technology, there will be an increasing need for high accuracy ...

Abstract: In this article, two approximate Radix-4 Booth encoders Approximate Radix-4 Booth Encoder1, 2 (AR4BE1 and AR4BE2) are. proposed to achieve great accuracy-cost tradeoff, and a series of ...
