Got my QuickStart propeller board....how do I connect it to my TV?

cbmeeks

OK, I cannot find anywhere that tells me HOW to connect the Propeller QuickStart board to my TV.

I got it to work (after finding demo code buried in the Mac application binary) by randomly inserting a wire from pin to pin (connected via RCA adapter I made).

I *think* it's pin 13. Anyway, I see text on the screen but obviously, it appears to be just chroma information. As other nearby pins show a rolling B/W signal so I assume I need to put this through an R-2R ladder to get a better picture.

But how? I have yet to find any tutorials that tell us how to hook things up. It's got to be out there. lol

Usually, you would think things like that would be in the code but I guess I'm missing it.

Thanks,

You can use the Propeller Demo Board schematic as a template, as most earlier demo programs have been written using these pins.

There are also one pin TV drivers. I have not used them yet.

You need 3 resistors.

Thanks everyone!

I didn't have those exact values but I used a 768, 383, and a 180 and it's PERFECT.

Wow. This is sweet.
