LED Demo with proximity sensor support for nexpaq development system

Dependencies:   MAX44000 nexpaq_mdk

Fork of LED_Prox_Demo by Maxim nexpaq

LED Prox 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, along with the MAX44000PMB1# peripheral module. This project demonstrates polling the proximity sensor to use it like a button and sending the information back to the application running on the phone, and the phone controlling the on board RGB LED to create different colors.

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