#123329 - Ok, why not do this
Responding to: ???'s previous message
debounce becomes a breeze if you handle all keypad processing in a timer interrupt. Then just disable the timer interrupt during LCD operations and no conflict will ever happen.

the disable will, at the worst make the debounce time a bit longet.

PS
in that scheme, you need separate the 'calculation' of the display and the actual writing to the display or the disable time may become prohibitive.
