3 MCC Melody GUI

This document provides information about the MCC Melody Core details instructions on using its features like the Toolbar, Easy View and Register Initialization/View.

3.1 Introduction

MPLAB® Code Configurator (MCC) Melody Core provides Libraries, Drivers, and Peripheral Libraries (PLIB) for the development of embedded software for Microchip PIC® and AVR® Microcontrollers (MCUs) and dsPIC® Digital Signal Controllers (DSCs). The 4 MCC Melody Components are customized via a graphical configuration tool, which generates highly efficient C code.

Resource Management Panel: The Resource Management Area has two views: The tree and the flat view. Both provide access to the complete list of software/peripheral components and the selected components for the current project configuration.

Application Builder Panel: A structured relationship manager with used resources, providing a clear visualization of a component's related dependencies and context in your project.

Composer Panel: When a peripheral, library or other external component is selected from the Project Resources Area, its corresponding configuration GUI is displayed in the Composer Area.

Pins Package Panel: Displays pins in graphical view and provides a zooming feature by the scrolling mouse wheel when the mouse is over the package view.

Pin Grid Panel: Displays pins in a structured table format,with lock and unlock features.

3.2 Melody Component Toolbar

The Toolbar provides quick access to commonly used functionality of Easy Views and Register views, such as Search , Text Size , Expand/Collapse and Track Change.

The toolbar is available for all Easy Views and Register Views.

3.2.1 Search

This feature allows users to quickly find specific information within the views.

Users can search across register names, settings names, descriptions, values and more in both Easy view and Register view.

Search across:
  1. Easy View
  2. Register Initialization/ Register View.
  3. Register names.
  4. Settings names.
  5. Descriptions
  6. Bit values

3.2.2 Text Size

Adjust text size using two buttons located inside the toolbar.

3.2.3 Expand/Collapse

This feature allows users to quickly show or hide the content within the groups.

Users can expand and collapse all the groups in both easy and register views by clicking on the buttons in the toolbar.

3.2.4 Track Changes

The Track Changes feature is enabled for Register Initialization/ Register View only (not enabled for Easy View) supporting tracking of Registers/Settings values concerning POR (Power-on Reset) values.

The Track Changes Drop-down is visible under the Toolbar and will be set to ‘None’ by default.
Table 3-1. Options
# Option Description On Selection

2 Highlight Register Changes from POR POR: Highlight default Register values as mentioned in the datasheet. Enables highlighted and downlighted icons beside each Register/Settings to represent changes only
3 Reset to MCC Defaults Resets the user-modified values to default MCC values
  1. Selecting ‘Reset to MCC Defaults’ will give a Confirmation window to proceed further.
    • Yes. Will reset the user-modified values to default values
    • No. Will be kept in same window without resetting any values
  2. Available for Register View only

3.3 Component Views

Different views are presented when configuring an MCC Melody Components (such as Libraries, Drivers, PLIBs), different views are presented, depending on whether an easy or very detailed configuration is required.

For more information, see MCC Melody Components.

3.3.1 Easy View

Easy View allows users to interact with the Graphical User interface.

Users can interact with the Graphical User interface and use it to configure peripherals parameters of registers and settings.

Table 3-2. Easy View Features
# User Interface Description
1 Easy View Tab When a peripheral, library or other external component is selected from the Project Resources Area, its corresponding configuration GUI is displayed in Easy Views,where user configure the peripherals and libraries
2 Collapsible Groups GUI controls (Register/Settings) are grouped according to their functionality, e.g., Software Settings, Hardware Settings, Interrupts
3 Configurable Controls User configurable parameters are reflected into Register Values and Firmware Code
4 Configuration-field help On-demand help for most UI components, which take users to the related

3.3.2 Register View

Register View or Register Initialization is a read-only tab. It shows the resultant values of the registers based on Easy View changes and Firmware code is generated reflecting these values.

Any module configuration using the Easy Setup tab will be reflected in the values displayed in the Registers tab.

Table 3-3. Register View Features
# User Interface Description
1 Register View or Register Initialization Tab Displays Register and Setting value
2 Collapsible Groups Each Collapsible Group represents the Register and collection of Setting bits within the Register
