I often get questions about how to measure voltage with microcontrollers. We will look at this topic, at the quality of built-in and external Analog-to-digital converters, and I will show you some “secrets.”
In this video, we will:
See how ADCs work
Look at how we can determine the quality of ADCs
Compare the ADCs of different microcontrollers with external chips
Learn how to tweak the calculations to get the best out of any ADC
See how we can extend the range of ADCs
Discover some “hidden” things of Microcontrollers and their ADCs
Look at different external boards and their usage
