FPGAs For MCU Guys

Electronics News Updates / Ibrar Ayyub

A little while ago, it struck me that I was getting tired of explaining what FPGAs are and how they work their magic to those of my chums who — thus far — have worked only with microcontrollers (MCUs), so I decided to write a three-part mini-series of articles to offer as an introduction. As

Adding ADC to Microcontrollers without ADC

Electronics News Updates / Ibrar Ayyub

I recently had the need to carefully measure a voltage with a microcontroller which lacks an analog-to-digital converter (ADC), and I hacked together a quick and dirty method to do just this using a comparator, two transistors, and a few passives. The purpose of this project is to make a crystal oven controller at absolute minimal
