Hi All,
a quick question or two.

How many people use the hd44780 driver and how many find it slow or too
slow?

Has anyone ever looked at optimising it for display speed? ie. only update
those bits on screen that have changed?

if not enough people care to be worthwhile doing an optimise, whats the best
place to change the 8 updates to say 1 a second?

for those who haven't looked lately you can now hook up a hd44780 display
with keypad using only 4 wires (plus power) and a shift register (and some
diodes and switches) http://members.xoom.com/andrewmuck/LCD.htm

if no one has any complaints, I will stop making changes and see if anyone
adopts it.

cya, Andrew...
