Hi all,

I googled for computer VGA Card circuit diagram or its information to learn its function and want to try to use it with microcontroller. But there is no such sufficient info. I wonder that the sea of info (google) is empty in this matter. Can any body help to find some circuit of simple old vga cards and how to give them data to display on VGA Screen. Thanks.

Yes it is useful but I need some cheaper around $10-20.

But is there any info to use old VGA cards which are so cheaper on old PC shop.

Hi thetrueman,
I think than oldvan is right. if you look more deeply in tinyvga.com:
http://tinyvga.com/avr-isa-vga
they offer a schematic and the source code in C. Should be portable to other microcontroller.
