Defining the Architecture 

Demonstration Features 

• Input system service and touch driver 

• Time system service, timer-counter peripheral library and driver 

• LCDC display controller and GFX2D GPU 

• 32-bit RGBA color frame buffer in external DDR memory 

• I2C peripheral library and driver 

• JPEG image stored in internal flash 

Creating the Project Graph  

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 9x60 Evaluation Kit BSP” and “Aria Graphics w/ PDA TM4301b 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 and the touch controller. 

Building the Application 

The parent directory for this application is gfx/apps/aria_quickstart. To build this application, open the IAR project at: gfx/apps/aria_quickstart/firmware/aria_qs_9x60_ek_tm4301b.eww. Once IAR is launched, simply build the application to produce the harmony.bin image. Copy harmony.bin to a FAT32-formatted SD card. The SD card must also contain the supplied bootloader binary needed to boot Harmony applications. Insert the card to the SDMMC1 port on the board. 

The SAM 9x60 build environment is similar to SAMA592. For more building information, see: Getting started with Harmony 3 on the SAMA5D2. 

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.

Configuring the Hardware 

Connect the ribbon cable from the display to the J16 connector on the back of the SAM 9x60 Evaluation Kit board. 

Power up the board by connecting the power adapter to power connector or a powered USB cable to the USB port on the SAM 9x60 Evaluation Kit board. The final hardware setup should be:

Running the Demonstration 

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):

When Make changes. Generate. Run. is touched, the button will toggle with each individual touch.
