With that in mind, if you want to use the GFX NTSC driver then you need add both the base NTSC driver along with the
GFX API as well to your project:
22.1 GFX Driver Architectural Overview
The idea of the Chameleon is that you use other people’s drivers, make your own and change them as you need them on
the Propeller side. Thus, we don’t want to spend too much time explaining how any particular driver works since you will
probably change it. However, the NTSC GFX API is worth covering for a little, so if you do want to create a game or
something more graphical, you can. Please refer to Figure 22.1 for the following paragraphs, I will assume you have some
experience in tile mapped graphics and game programming for the following explanations.
