Not to HiJack the PropStick Video Driver thread, but on video output in general
I've seen quite a number (three to be exact) of methods of connecting the propeller to·one video source·or another.· Could someone please verify the following?

Thanks!

- Composite output.· There are two versions of this connection, one with three, the other with four resistors.· I believe the one with 4 resistors includes sound or is for broadcasting the output.· Can the four resistor version be used for either mode?
- VGA output.· What should be done with the unused connections in the DB15 female housing?
- RGB output.· I believe a subcomponent of the VGA output is RGB.· Is this the same single that would typically be sent to the RGB inputs on a VCR/DVR?
- I have an 1702 Commodore Monitor that has Luminance and Video inputs (and audio, but that will come later).· How would I create that type of video output?
Thanks!

1) Composite output to TV: It works fine with only three resistors. I haven't tried it with four.
2) VGA: unused connection in housing: I left them unconnected. It worked fine without them.
3) RGB: don't know. But looking at the connector schematic, it does look like there is an RGB output. Try it?
4) Commodore with Luminance and Video: don't know. Maybe try the TV output connect to the Video port on the Commodore?
THe commodore connection didn't work... [noparse]:([/noparse]
I'm going to have to do some some more stuff... but, I do have an old VGA monitor that it should work with... My dev board is 99% completed...

I got the cheaper.
Anyway, it keeps the clutter from building and provides an outboard, all hardware solution to using the computer's VGA.
It has a typical remote that jumps you between computer and video. Also, you want volume control.
I am having trouble with determining is RGB and VGA use the same plug.
The Commodore is ancient. I suppose you can eventually get software and interface for it. Quite odd.

..C64 has floppy & hard drive access, as well as printer... & I'v LOTS and LOTS of C64 equipment...
Their serial interface protocall is very simular to the SERIN/OUT interface and protocall.. More on that in another thread...

Check your PM to continue the JACS discussion.
why green is to the right in the saturated colors, but in the middle in the desaturated colors; why is blue in the
middle in the saturated colors, but to the left in the desaturated colors (and to the right)? It looks like there is
a 180 phase shift from the saturated to the unsaturated colors, and I'm not sure why.

another set of colors where as the luminance goes up, the saturation goes down.
I'm trying to figure out how to map this color space to RGB (and from this information, how to map RGB into this color space); I think you've given
me the clues I need. Thanks!
(And like others, I'm amazed at how responsive you and everyone at Parallax are. You guys must really have almost as much fun as all us
tinkerers!)
