Hey guys,
I have a circuit that has one atmega128 with a typical parallel 20x2 lcd display and a 5 button keypad. I have used all of the outputs on the first atmega128 and I would like to add a second atmega128 to handle some other applications, but use the same keypad and display. Is that possible and what would be a standard hookup between the two for that kind of interface with the capability to control both IC's with the same keypad/display?
Thanks for any advice,
J
