28.1.5 Dual NTSC / VGA Printing Demo
One of the cool things about the NTSC and VGA terminal tile drivers is they have the exact same base features. Which
means that porting your code to work on NTSC or VGA is usually a matter of changing API prefix function names with
from “NTSC” to “VGA” and vice versa. Of course, the advanced “gaming” tile engine support is only for the NTSC driver;
however, no one is stopping you from using or making a more advanced VGA drivers on the Propeller. I simply choose
not to this time around. In any case, this demo is just a “Hello World” demo that prints both on the NTSC and VGA
monitors at the same time to show you how easy this is. Figure 28.5 shows the demo in action.
