Technical Overview
The demo simply uses the NTSC GFX to animate the top and bottom overscan colors (this is only supported with the
default2 version of the driver and the NTSC system). Below is an excerpt of the code from the main while loop that
performs the animation.
The code simply formats a Propeller compliant color and then calls the API function to change the top and bottom
overscan color, that’s it.
Summary
This demo shows how easy it is to use the advanced GFX tile engine API functions, in particular to animate the overscan
color on the NTSC display.
