MPLAB® Harmony 3 Reference Applications

MPLAB® Harmony 3 is an extension of the MPLAB® ecosystem for creating embedded firmware solutions for Microchip 32-bit SAM and PIC® microcontroller unit(MCU) and microprocessor unit (MPU). Refer to the following links for more information.

This repository contains the MPLAB® Harmony 3 Reference Application Package.

Reference applications are standalone applications which demonstrates specific features or capabilities of Microchip 32-bit SAM/PIC MCUs and MPUs. These applications are developed on Microchip 32-bit SAM/PIC MCU and MPU development boards/kits.

In addition to having the MCU/MPU, the 32-bit SAM and PIC MCU/MPU development boards/kits also provide support to exercise the features of MCU/MPU through additional hardware like displays, communication buses, transceivers, sensors, external memories, etc. The additional hardware features are available on the MCU/MPU development boards/kits or is available as plugin through interface headers like mikroBUS Click or Xplained Pro extensions.

Following are the typical application types in this repository

  • Large feature-rich applications involving integration of several technologies like Audio, USB, TCP/IP, Wireless, Security, Low Power, RTOS, etc.
  • Applications demonstrating certain capabilities of the Microchip 32-bit SAM/PIC MCUs and MPUs. For example: Low Power application on SAM L21 Xplained Pro Evaluation Kit demonstrating idle and standby modes
  • Applications demonstrating capabilities of Microchip 32-bit SAM/PIC MCUs and MPUs development boards/kits (Curiosity, Nano, etc.) which allows extending hardware capability through mikroBUS Click or Xplained Pro extensions
  • Getting started applications pertaining to the Microchip’s MCU/MPU products. These getting started applications demonstrates usage of MPLAB Harmony 3 framework by exercising commonly used peripheral features

The above application types serve as a reference source to evaluate solutions on 32-bit SAM/PIC MCUs and MPUs by developing applications using MPLAB Harmony 3 software framework.

Repository and demo application support:

  • The following table lists the fundamental and few technology specific repositories in MPLAB Harmony 3 Software Framework
Repository # Demo Application
csp Simple applications that directly control the SAM and PIC peripherals
core Applications that use the drivers and system services that have advanced capabilities and a higher level of abstraction that gives better hardware independence
usb Applications that demonstrate the capabilities of the MPLAB Harmony USB stack
net Applications that demonstrate the capabilities of the MPLAB Harmony TCP/IP stack. These applications use well-known protocols like TCP, UDP, HTTP, SMTP, etc.
gfx Quick start applications that demonstrates MPLAB Harmony Aria/Legato Graphics Libraries
gfx_apps Non quick start applications that demonstrates MPLAB Harmony Aria/Legato Graphics Libraries
audio Applications that demonstrates capabilities of the MPLAB Harmony audio offerings, drivers for hardware codecs that can be connected to development boards, audio decoders, etc.

Note:

The above is not an exhaustive list of all MPLAB Harmony 3 packages and corresponding application offerings. Refer the MPLAB Harmony 3 GitHub Launch page to view the complete list of MPLAB Harmony 3 packages. In each of these packages refer the underlying “apps” folder for the applications offering.
