Step 5.2 - Configure the Graphics Controller

In the MHC Options tab, expand the Harmony Framework Configuration > Drivers > Graphic Controllers selection tree.

As you have enabled the Graphics Library, the MHC enables the Graphics Controller automatically. In addition, as you have selected the Board Support Package (BSP) for this project, the BSP takes care that the appropriate Graphics Controller for the hardware is selected. As we selected BSP related to the MEBII board, the MHC selects the Low-Cost Controllerless (LCC) as the Graphics Controller. Look into the below graphics for the Graphics Controller configuration.
