MCC Melody Device Support for AVR MCUs (Latest Release notes)

Getting Started Use Cases

To get started with MCC Melody, training materials have been built into the API references for each MCU Family supported: AVR, PIC16F/PIC18F and dsPIC33).

Note: Find a supported MCU here: MCC Melody API References and MCU Device Support.

Many components have a "How to Use the …." section, which include a number of use cases consisting of the following:

Required configuration settings of the component (and potentially other components).
Schematics of the board used, e.g., In Pin Grid View: Select a LED pin as an Output, renaming it to LED.
Code snippets to add to your application.

The use cases can be run on any of the MCUs associated with the that MCU Families API reference and some even more broadly. Only minor modifications will be required to run the use cases on a particular board, e.g., selecting the analog input channel.

Videos: Some of the use cases include videos, which give a high level overview of how to run the use cases. These may be especially useful if new to the MPLAB Tools Ecosystem.

Note: While the videos give an overview of the use case, always check the configuration settings and code snippets for the latest use case version. Use cases will be updated when changes or improvements are made to the component's configuration setting options or the generated API.

Videos Running MCC Melody use case code snippets for AVR:

Many of use cases build on the following components, so this is a good place to start if you are new to MCC Melody:

Recommended starting point: UART Driver, Timer/Counter A PLIB Driver and the Data Streamer Library.
Videos also included for: RTC PLIB Driver, AVR Event System.

Library Reference

MCC Melody Libraries implement 'Middleware' functionality, such as protocols. They are independent of MCU peripherals, providing a highly abstracted portable application program interface.

MCC Melody Components - Libraries

Data Streamer Library - Implements the Data Stream protocol needed to plot multiple variables on the MPLAB Data Visualizer.
Data Visualizer Run Time (DVRT) Library - Supports the the DVRT functionality of the MPLAB Data Visualizer to "watch" and plot project variables at run time on the Data Visualizer plugin window.
EEPROM Library - Provides APIs to support various EEPROM operations for a wide range of I2C EEPROM devices.
Ethernet Drivers Library - Provides drivers for the ENC28J60 and ENCX24J600 family of ethernet controllers.
TCP/IP Lite Driver Library - Facilitates the development of TCPIP-Lite applications for 8-bit microcontrollers.
Temperature Sensor Off-chip Device Driver - Provides an API interface to access a temperature sensor's functions like reading temperature, converting from one scale to another, and selecting power modes.
USB Device Stack Library - Enables users to define descriptors for selected USB Device classes.
Off-chip Libraries - Generates firmware drivers for independent off-chip devices that are interfaced with the microcontroller via common communication protocols or GPIO. The following off-chip device drivers are supported:

Driver API Reference

MCC Melody Drivers support both Configuration and Firmware portability, providing an easy to read and efficient abstraction to the functionality of the peripheral.

MCC Melody Components - Drivers

Configuration: Easy View + Register Initialization panel.
Generated code: PERIPHERAL_Initialize( ) + API to develop application functionality.

PLIB Driver API Reference

MCC Melody Peripheral LIBraries (PLIBs) provide an API to support periperal specific functionality. (Optional) Portable interface to support firmware portability, but in general only provide non-portable interface to peripheral functionality.
