Now Support for PIC and SAM MCUs with MPLAB Harmony version 3

Users of MPLAB® Harmony, a flexible, fully integrated embedded software development framework for 32-bit microcontrollers (MCUs) and microprocessors (MPUs), are now able to use MPLAB Harmony v3. This release extends software framework support for SAM MCUs and MPUs in the MPLAB development environment for the first time. The first 32-bit families to be supported in MPLAB Harmony v3 include the PIC32MZ EF, PIC32MZ DA, PIC32MK, SAM E7x, SAM V7x, SAM S7x, SAM C2x , SAM D2x, SAM D5x/E5x MCUs and SAMA5D2 MPUs.

MPLAB Harmony v3 includes the MPLAB Harmony Configurator (MHC) tool, a set of modular device and middleware libraries and numerous example applications, all of which are designed to help you quickly and easily develop powerful and efficient embedded software for Microchip’s 32-bit PIC® and SAM devices.

MHC is an easy-to-use development tool with a Graphical User Interface (GUI) that simplifies device set up, library selection, configuration and application development. The MPLAB Harmony Configurator 3 is available as a plugin that directly integrates with the MPLAB X Integrated Development Environment (IDE). To provide additional flexibility to your programming experience, MPLAB Harmony can now also be used as a stand-alone tool outside of MPLAB X IDE. This enables you to start a new project in your native development environment.
