VGA Interface Using Only 74xx IC’s
Posted October 6, 2011 by Chris
To go with my other vga oriented projects here’s a VGA interface that is built entirely with TTL discrete logic chips. I built it primarily for the 7400 contest over at dangerous prototypes, so give a comment over there if you like the design. This interface outputs the proper Hsync and Vsync signals using some 74193 counters and uses an 8-state machine to output different color signals to an LCD.

Hi,
Nice work!
FYI I found a “masochist” who write some assembly to get pictures from its arduino: look at VGAout by Nabe

Thanks,
