Hardware peripherals to read quadrature encoders (and the quadrature encoder example) count steps by looking at the sequence of phase states read from a quadrature encoder. To estimate the encoder ...

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 ...

An unexpected revisit to my earlier post on mouse encoder hacking sparked a timely opportunity to reexamine quadrature encoders, this time with a clearer lens and a more targeted focus on their signal ...

This project implements closed-loop position control of a Pololu 70:1 metal gearmotor (4754) using an Arduino UNO R4 WiFi and a Pololu Dual G2 High-Power Motor Shield 24v14 (M1). A panel rotary ...

Rotary quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...
