RGBS w/ Csync results in scrambled image #210

Closed ghost closed 3 years ago

ghost commented 3 years ago

I've had some good luck with the GBS-C project thus far with both YPbPr and RGBHV via the DE-15 connector, but have yet to have any success with RGBS when using the appropriate header connected to a SCART socket.

I have the socket wired as outline by Tom Dalby's wiring diagram, albeit omitting the sync stripping circuitry and connecting the sync line directly but have only managed to output scrambled images as though the sync signal were not there at all. Going into a conventional display directly proves to not be an issue. I also have the 100ohm resistor across the sync and ground lines as outlined in the wiki, along with the Si5351 clock generator installed.

Below is a photograph of what is being output: (For reference, this is meant to be the main menu from a SCPH-102 model PSone's BIOS.)

And attached is an exerpt from the GBS-C log. gbsc log exerpt.txt

If you require any more details to help figure this issue out, please let me know and I'll do my best to give you what you need. Thankyou!

Disregard this issue, the problem I found was with my SCART cabling and several pins not being properly grounded.
