Need code suggestions for "colorful" VGA output demo

WBA Consulting

I am setting up a test jig where I need to generate a VGA signal that allows for an easy way to ensure all connections are made properly. I need a simple VGA demo that will utilize at least 16 colors. I can use Chip's VGA demo code that shipped with the Propeller Demo Board, but I was hoping somebody would have something else to suggest. Maybe some sprites jumping around the screen?

It's only a single sprite but it's big ... http://forums.parallax.com/showthread.php/142764-FYI-VGA-400x300-scanline-driver-(SVGA-timing-single-cog)?p=1153215&viewfull=1#post1153215

kuroneko: the bouncing ball should do the trick! Thanks for the quick reply. The setup will only be generating video and playing a WAV file, so I should be able to join the bouncing ball code with the KISS WAV player and call it done.
Do you happen to know how many cogs the bouncing ball code takes up?

EDIT: I re-read the thread and caught that it takes 5 cogs. Since the KISS WAV player takes only 1 cog, I should be set. Thanks again!

Update: I began working with both the Bouncing Ball code and the KISS WAV code separately. Both were working perfectly, but when I went to combine them for a final version, I ran out of longs. :frown:

I am still using the KISS WAV player, but now I am using the 640x480 Tile Map driver from Kye and just throwing some colored boxes in basic test patterns. My first draft of combined code works excellent. It simply displays a title, starts a loop of three WAV files (left, right, stereo), and runs through two different test pattern loops. Works very well for my need. I will post the finished setup as a project once it is moved off of the Quickstart/QS HIB setup. (if the touchpads on the QS are touched during playback, it wreaks havoc on the WAV player)
