This is something that will have to be built into the video controller. Perhaps opcode 4 should be a set sync mode operation with the bottom eight bits being the sync mode bits: 7: reserved 6: reserved 5: reserved 4: reserved 3: hsync polarity (1 - positive, 0 - negative) 2: vsync polarity (1 - positive, 0 - negative) 1: composite sync 0: sync on green
This might not be a vid controller setting at all. Rather, it's probably a configuration of the DAC that tells it how to interpret composite sync (which we just put out on h and v together or something). _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
