Harmony Configurator (MHC)
MPLAB Harmony Integrated 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
Provides functional interface for Microchip
PIC32 scalability
Implements part-specific features
