3.1.2 MPLAB® Harmony v3
MPLAB® Harmony v3 is a fully integrated embedded software development framework that provides flexible and interoperable software modules to simplify the development of value-added features and reduce the product’s time to market. MPLAB Code Configurator (MCC) is a free graphical programming environment that generates seamless, easy-to-understand C code that can be used in user’s 32-bit application development. MPLAB Harmony v3 supports all Microchip’s 32-bit MIPS, Arm® Cortex® based MCU and MPU device families. Device and embedded software libraries can be configured with MCC, a GUI-based configurator integrated into MPLAB X IDE, which provides a unified interface to all the features of the embedded software framework.
MPLAB Harmony v3 is an extension of the MPLAB ecosystem for creating embedded firmware solutions for 32-bit Microchip devices. For better installation and configuration management the software is available through GitHub.
MPLAB Harmony v3 has a layered architecture that consists of several software modules. These modules are portable, compatible to each other and they communicate and exchange data and information with each other. The low-level Peripheral Libraries (PLIBs) are simple functions to initialize and control peripherals and basic device features. The System drivers enable the configuration of general functionality, often used by other peripherals, such as Pins, Interrupts and the System Clock. Drivers depend on PLIBs and abstract the hardware details away from Libraries and applications. Libraries use drivers and system services for device independence, and they provide support for networking, USB, cryptography, and other capabilities often required by today’s embedded applications.
