Introduction to PIC Programming Using C: Byte Lights With the ADC – Part 2: The Mock-Up

Reading Time: 22 minutesIntroduction Welcome back! In this series, we’re still continuing our goal to understand analog-to-digital conversion (ADC) of a PIC microcontroller, and how to program one to accept and convert an analog input. It is my personal goal to help guide you to do this in a way that I learned from a terrific book I […]
