MPLAB® Harmony Graphics Composer (MHGC) Overview

The MPLAB® Harmony Graphics Composer (MHGC) is a graphical user interface design tool that is integrated as part of the MPLAB Harmony Configurator (MHC). This tool enables you to easily configure and visually design for the MPLAB Harmony Graphics Primitive Library and the MPLAB Harmony Graphics Object Layer.

The Graphics Composer performs the following tasks for you:

  • Import image and font assets
  • Create screens and schemes
  • Add objects to screens
  • Configure objects
  • Generate MHC configuration
  • Upload program to the device

Graphics Composer Screen

When MHGC is opened, the Graphics Composer Screen is displayed (see the associated image). This screen is the same size and resolution as your actual display, and it simulates how objects will appear on the screen.

Graphics Composer Tool Box

You will find the Graphics Composer Tool Box in the top left pane. It shows the various objects that can be added to the display screen. You will see two types of objects in this window:

  • Primitives (basic objects: Line, Rectangle, Circle, Image, Text)
  • Widgets (complex objects: Button, Check Box, Progress Bar, Meter, etc…)

Graphics Composer Properties

The Graphics Composer Properties tab is displayed in the right top pane. This allows you to view and edit the properties of the selected screen or object.
