This firmware demo is a simple test of the graphic test pattern commands in the firmware. The board does not appear as a USB device. When the board is power up, this display below appears. You can connect a terminal app window to the COM port if desired.
Clicking the push button (top left corner) causes a
series of test patterns
to be displayed. Some of them are shown below.
This demo firmware is very basic and simply tests that the board and LCD is functional.
For a more comprehensive demonstration, see the USB HID Graphics Demo that configures the board as a USB Human Interface Device. PiXCL 11 includes a comprehensive set of commands to write graphics objects and text to the LCD.
