After getting the SCART-Genie done and perusing the internet. I came across JediMatt's project page on using the Geneve with a VGA monitor.
so I said what the hell, lets try it all Geneve users need options. Also the SCART monitors are hard to come by.
This project was originally proved out by JediMatt42 HERE
I purchased myself a GBS8200 RGB to VGA converter HERE
JediMatt and myself emailed back an forth on this a while back and he answered quite a few of my questions.
Thanks to JediMatt's wiring diagram. I was able to get mine up in running in no time on a breadboard. I did change a couple of things such as:
- use of a 8pin din socket as used on my SCART-Genie's
- added a 470 ohm resistor to the Sync ouput line
- added a 1k resistor to the audio line
otherwise it is exactly the same. It looks very good on VGA. With this you can only use external speakers or your monitor must have a line in for the speakers.
attached are some pictures and a concept design PCB image. Not sure why my camera makes my 910mp text look off-white, but it looks good. No shadowing.
I did find out that you want to make sure you have an adequate power supply for the GBS, it calls for 2.5 amp 5v. If not you will get scrolling, blanking on the monitor and various other stuff.
i may modify the PCB design to act like a daughter board and just plug right on top of the GBS8200 unit. Then the only wires that will have to be connected is the 5v and ground from the GBS8200 to the Genie.
