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 project focuses on stabilizing an inverted pendulum — a classic problem in control systems — using an Arduino-based setup. Since the pendulum is naturally unstable, the goal is to keep it ...

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 scenario demonstrates how to configure a timer in encoder mode to determine the rotation direction. Initialization phase: At main program start, the mx_system_init() function is called. It ...

To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...

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 ...
