Any one know of any good sites that will help me learn the basics on
using an Hitachi LCD 44780 with the PIC 16f84. Or if any one can post just
a simple assembly prog just to clear the screen and put one character on
it...that would be great I can learn from there.

THis http://www.optrex.com/pdfs/Dmcman_full.pdf manual explains in great
detail what is required. The "hard" part is getting the display throught
the initialization sequence. Just be a little conservative on the timing
and, if possible, check it with an analyzer or scope to verify that what
you want to happen, is happening.
