Temp Prox Demo

MAX32625NEXPAQ development module

This project is a demonstration application for the MAX32625NEXPAQ development module and a MAX3010x sensor.

This project demonstrates polling the proximity sensor to use it like a button and also polling the temperature sensor and sending the information back to the application running on the phone, and the phone controlling the threshold for the proximity sensor and controlling the on board RGB LED to create different colors.
