I wrote a bit of VHDL for generating inc/dec pulses from quadrature rotary encoders like the CTS Electrocomponents ones I bought from Digikey for a project I worked on recently. This debounce circuit ...

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 ...

All engineers know how to use their digital oscilloscope to automatically measure basic parameters such as peak-to-peak voltage, rise time, or frequency on waveforms with a few button presses. Some ...

Optical rotary encoders, sensors used everyday in industrial applications, provide instantaneous and continuous data on rotational motion. Designed to monitor speed, position, distance, and direction ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. In many applications, accurately sensing the position of an electrically controlled mechanical device such as a motor is critical.

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 ...

Because they have higher resolution and accuracy, these encoders are often used in applications that need high precision, ...

Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...
