legato_adv_ck_cu_wqvga.X
Defining the Architecture
The architecture for this configuration is the PIC32CK_GC Curiosity Ultra with High-Performance 4.3” WQVGA Display Module with maXTouch® Technology.
User touch input on the display panel is received through the PCAP capacitive touch controller, which sends a notification to the Touch Input Driver. The Touch Input Driver reads the touch information over I2C and sends the touch event to the Graphics Library through the Input System Service.
Demonstration Features
- Legato Graphics Library
- Input system service and touch driver
- Time system service, timer-counter peripheral library and driver
- 16-bit RGB565 color depth support (65535 unique colors)
- EBI peripheral library and driver
- 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 PIC32CK_GC Curiosity Ultra BSP and Legato 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 apps/legato_adventure. To build this application, use MPLAB X IDE open the apps/legato_adventure/firmware/legato_adv_ck_cu_wqvga.X project file.
The following table lists configuration properties:
| Project Name | BSP Used | Graphics Template Used | Description |
|---|---|---|---|
| legato_adv_ck_cu_wqvga.X | PIC32CK_GC Curiosity Ultra | Legato Graphics w/ PDA TM4301B Display | Legato GFX on PIC32CK_GC Curiosity Ultra board with PDA TM4301B 480x272 (WQVGA) Display |
**_NOTE:_** 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
The final setup should be:
Configuring the 4.3-inch WQVGA Display requires disconnecting the ribbon cable that connects the display to the interposer board.
First, release the ribbon cable from the interposer board. Next, release the black clamp on the RGB565 connector and turn the display over. Finally, insert the ribbon cable into connector and close the clamp.
The board can be debug via the on-board EDBG via the Debug USB port , or by using the ICE4 Debugger and the ICE4 Cortex-M Trace Adapter Board.
Running the Demonstration
The application first boots to an animated Splash Screen. Once the Splash Screen animation completes, the application boots to a Main Screen.
When at rest, the demo will cycle through idle sprite animations. Various areas of the screen are touch interactive
If initiated to run, the lamb sprite will run to the end of the screen, and play out a sequence of smacking into a wall, hurt and dizzy animations.
Tap Jump and the lamb will play out a jump animation.
