MiSTer FPGA 15-pin Pinout

[Mikey]

This must exist somewhere.

Anyone?

A pinout for the MiSTer FPGA "VGA" port?

It changes with each daughter board revision.
The schematics are available for each on github. Nice detailed pics.

It's the QMTECH version.

Got it. Thanks.

I should make a point of something that is incorrect with the MiSTer VGA output.

VGA monitors accept 3 types of sync input.
RGBHV 5 pins is the most common.
RGsB 3 pins Sync on Green is quite common also.
RGBs 4 pins I am yet to find a VGA monitor that does not accept this. They will take Csync on the Hsync pin then the monitor will strip it into HV sync and do its thing.
When running RGBs with a MiSTer the lonely Vsync pin is ACTIVE HIGH 5V!!! (Turns into a scart blanking signal)
You need to cut the pin if feeding this to a VGA monitor else it will drop sync or not even work.

All standard assumptions for a device with robust output options on a DE-15/HD-15. You'll also find sync on the green pin using YPbPr component.

For Y/C "svideo" pin 1 is luma and pin 2 is chroma. Composite sits on pin 1.

I understand the composite signal may need some additional attenuation (?), but I don't know the details or care. I'm sure there's answers on the MiSTer forums.
