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
