LED Demo

MAX32625NEXPAQ development module

This project is a demonstration application for the MAX32625NEXPAQ development module. You will need the nexpaq application and a compatible phone to run this demo. This project demonstrates sending button information back to the application running on the phone, and the phone controlling the on board RGB LED.

Go to the nexpaq developers hub for details on how to load the code for the tile into the application.
