The horizontal resolution is nowhere near real VGA (it's equivalent to 160-320 pixels), but the timing is almost correct. Color depth is one bit per color. I used all but one signal, so one could add one more bit to, say, green. One could probably free another bit by multiplexing HSync and VSync. The program does a number of evil things, including the disabling of interrupts and the display refresh, to gain memory bandwidth and to have more predictable timing. - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
