RGB-HV output #502

Closed oziphantom closed 12 months ago

oziphantom commented 1 year ago

Is it possible to get RGBHV output and not RGBs output?

Basically I'm looking to get VGA -> RGBHV which it seems nothing does.

Nuck-TH commented 12 months ago

VGA is RGBHV by definition. Or you mean VGA 15khz?

ramapcsx2 commented 12 months ago

The default output is RGBHV already?

oziphantom commented 12 months ago

Say the 640x480 at 60hz or possibly SVGA spec of 800x600 at 60hz transmitted via a DE-15 connector to analouge RGB 576i 0.7 p-p with a 15khz Horizontal rate at 50hz vertical or 480i at 60hz vertical suitable for a DB9 pin RGB with a H and V sync output.

I guess you mean you want to use the bypass function, but with H+V syncs. That's something the chip can't do, or I haven't found out how to do it.

Also this chip can't do framerate conversion.

seems "GBS-Control" and this "GBSC" https://www.ebay.com.au/itm/314802317450 are not the same thing, hence my confusion. Thanks for your help.

Well, just as info: This is the same, though they added a bunch of hardware to make it more convenient. It still runs this software without any modifications (as far as I know) :)
