MPLAB® Harmony 3 is a software development framework consisting of compatible and interoperable modules that include peripheral libraries (PLIBs), drivers, system services, middleware, and third-party libraries. The MPLAB Harmony Configurator (MHC) is a GUI-based tool that provides an easy way to enable and configure various MPLAB Harmony modules. The MHC is a plug-in to the MPLAB X Integrated Development Environment (IDE). You can find more details about MPLAB Harmony v3 at https://www.microchip.com/mplab/mplab-harmony This video introduces PIC32MZ DA Curiosity Development Kit and explains how to create a simple application on Microchip's PIC32MZ DA based on MIPS Core 32-bit microcontroller using Harmony v3 MHC. The application demonstrates an LED (RGB LED) toggle on a timeout basis and prints the LED toggling rate on the serial terminal. The timeout periodicity will change from 500 milliseconds to One second, Two seconds, Four seconds, and back to 500 milliseconds every time pressing the switch SW1 on the PIC32MZ DA Curiosity Development Kit. Additionally, The application uses the onboard temperature sensor to periodically print the current room temperature on the serial terminal when pressing the SW2 on the PIC32MZ DA Curiosity Development Kit.
