6 Assignment 5: Differential ADC

In this assignment, the Differential mode of the ADC will be demonstrated. In Single-Ended mode, the ADC reads the voltage of a single selectable input source, while in Differential mode, the ADC reads the voltage difference between two input sources.

For this assignment, the Force Click board will be used as one input source, while the other input will be the internal voltage reference AC0 DACREF.

The Microchip Studio Solution Assignment5 includes the required starting point for this assignment and should be available in the training material folder at the following path: Assignment5.

  • Objectives
    • Configure the ADC for Differential mode using the Force Click board as MUXPOS and DACREF0 as MUXNEG
    • Use the Data Visualizer to graph received ADC results
