This aria_quickstart project uses an OLED1 Xplained Pro display panel that is connected to the E54 Xplained board. The display panel has an SSD1306 display controller that communicates to the E54 using the SPI peripheral. The SSD1306 contains a frame buffer and the Aria graphics library uses the SSD1306 driver to write pixel data to the SSD1306 frame buffer. 

• ILI9488 SPI display driver 

• 16-bit RGB565 color depth support 

• JPEG image support 

• SPI driver 

The Project Graph diagram shows the Harmony components that are included in this application. Lines between components are drawn to satisfy components that depend on a capability that another component provides. 

Adding the “SAM E54 Xplained Pro BSP” and “Aria Graphics w/ OLED1 Xplained Pro Display” Graphics Template component into the project graph will automatically add the components needed for a graphics project and resolve their dependencies. It will also configure the pins needed to drive the external peripherals like the display controller. 

The parent directory for this application is gfx/apps/aria_quickstart. To build this application, open the gfx/apps/aria_quickstart/firmware/aria_qs_e54_xpld_oled1.X project file. 

The following table lists configuration properties:

Important!

This application may contain custom code that is marked by the comments // START OF CUSTOM CODE ... and // END OF CUSTOM CODE. When using the MPLAB Harmony Configurator to regenerate the application code, use the "ALL" merging strategy and do not remove or replace the custom code.

The final setup should be: 

The OLED1 Xplained Pro display board is connected to the SAM E54 Xplained Pro board thru the EXT1 connector. 

When power-on is successful, the demonstration will display a similar menu to that shown in the following figure (different configurations may have slight variation in the screen aspect ratio):
