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.
