Software and Hardware Solutions for the 32-bit Designer
Introduction
MPLAB Harmony is a flexible, abstracted, fully integrated
firmware development environment for PIC32
microcontrollers. It enables robust framework development
of interoperable RTOS-friendly libraries with quick and
extensive Microchip support for third party software
integration. MPLAB Harmony includes a set of peripheral
libraries, drivers and system services that are readily
accessible for application development. The code
development format allows for maximum re-use and
reduces time-to-market.
Benefits
■ Faster time-to-market
■ Improved code interoperability
■ Simplified support
■ Improved 32-bit scalability
■ Enhanced third party software integration

Hardware
Software Framework
Application Layer
■ Implements desired overall behavior
■ Abstracted hardware access
■ Allows for easy port across PIC32 parts
Common System Services
■ Provides common functionality to avoid duplication
and conflicts
■ Eliminates complex interactions and interdependencies
between modules
■ OSAL provides OS compatibility and interface
■ Manages shared resources
■ Supports low-level configuration and board
support package
Middleware Layer
■ Implements complex libraries and protocols
(USB, TCP/IP, file systems, graphics)
■ Provides a highly abstracted application program interface
■ Libraries are thread safe and RTOS ready
■ Built on drivers, PLIBS, system services
■ Supports third party library integration
Device Driver Layer
■ Provides highly-abstracted interface to peripheral
■ Controls access to the peripheral
■ Manages multiple hardware instances and software
clients with select drivers
■ Manages peripheral state and multiple
peripheral instances
■ Accesses hardware via PLIB
■ Supports blocking or non-blocking code
Peripheral Libraries (PLIB) Layer
■ Provide functional interface for Microchip
PIC32 scalability
■ Implements part-specific features
