Human Machine Interface (HMI)
The MPLAB Harmony Graphics Composer Suite provides tools for creating advanced graphics content, supporting 24-bit color, multi-layer graphics, and touch gestures.

Digital Audio and Bluetooth
The framework includes a Bluetooth Audio Package for audio playback and control, supporting various audio protocols and profiles. It also offers audio decoder libraries and USB audio device libraries for implementing USB audio classes.

Basic Libraries and System Services
Peripheral Libraries (PLIBs) offer functions for controlling PIC32 MCU peripherals, compliant with MISRA-C:2012 standards. Additional libraries include Class B safety routines, DSP Fixed-Point Math Library, Cryptographic Library, and File System service.

Overview
The document provides an overview of the MPLAB Harmony Integrated Software Framework, detailing system services, bootloader configurations, operating system abstraction layer, and third-party partnerships. It also covers board support packages, application development tools, and resources for support and training.

System Services
MPLAB Harmony System Services manage shared resources to prevent conflicts among drivers, middleware, and applications. Key services include clock, console, debug, device control, DMA, interrupt, messaging, ports, random number generator, reset, timer, and watchdog timer.

Bootloader
The bootloader enables firmware upgrades on target devices without external programmers, supporting configurations like UART, USB, Ethernet, and SD card.

Operating System Abstraction Layer (OSAL)
OSAL provides a unified interface for Real-Time Operating Systems (RTOS), supporting FreeRTOS, OpenRTOS, Micrium μC/OS-II, Micrium μC/OS-III, ThreadX, and embOS.

Third-Party Partnerships
MPLAB Harmony collaborates with industry leaders in RTOS, IoT, security, and graphics, including Express Logic (ThreadX), FreeRTOS, Micrium, PubNub, iREASONING Networks, SEGGER, WITTENSTEIN high integrity systems, and wolfSSL.

Board Support Packages (BSPs)
BSPs provide code and configuration for board-specific hardware, supporting various development tools and allowing customization for application-specific needs.

Application Development Tools
A range of starter kits and development boards are available for connectivity, graphics, and digital audio applications, including PIC32MX, PIC32MZ, and chipKIT boards.

Resources and Support
MPLAB Harmony offers downloadable resources, user support through forums, self-paced training, and a one-stop shop for licensing and support. Microchip provides extensive technical support and training resources globally.
