This software is available in the

The demo shows how to use the
demo shows the user how to enable the touch screen, create buttons, and use graphics primitives
including colors and images.
The program begins by calibrating the touch screen. There is a routine that detects the four corner
coordinates to determine if an eligible rectangle boundary is formed. If the calibration was incorrect, a
message displays on the screen indicating the calibration failed. When successful, the calibration provides
a reference for all button presses throughout the rest of the program.
The next step is to select the mode of the program: display primitives or images. Each mode simply cycles
through without user interaction to show features of the display. In the graphics primitives mode, the
following primitives are shown:
• Pixels
• Lines
• Circles
• Rectangles
