First, it should be amazing to you that in a few lines of code you are generating a NTSC color text display! Reviewing the
code, the program starts, waits for the Propeller to boot (don’t forget to do this), then the call to clear the screen, and we
enter the main while loop. Here a redundant call to set the color is made and the text is printed to the NTSC terminal with
NTSC_Term_Print(…) – that’s it!
Summary
This demo shows how easy it is to get NTSC terminal like text output going on the Chameleon.
28.1.2 NTSC Glowing Top/Bottom Overscan Demo
This demo simply uses the NTSC tile graphics engine extensions to glow the top and bottom overscan colors on the
display. The default2 driver uses a high performance tile engine that we developed that supports scrolling, 4 colors per
tile, large playfields and a lot of more. One of its simple features is the ability to control the top and bottom over scan
colors on the screen. This demo simply cycles thru those colors and shows you how to make calls to update the overscan
color registers in the tile engine running on the Propeller chip. Figure 28.2 shows the demo in action.
