This has been posted to the list before, but I think it bears repeating.
Anything that includes the Hitachi HD44780 or a clone, this is the best
reference material I've found.

Start here - http://www.wizard.org/auction_support/lcd1.pdf
move on to here - http://www.datsi.fi.upm.es/docencia/Micro_C/lcd
/HowtouseLCD2.pdf

The first one starts with dip switches and a pushbutton and puts text on
the screen.

Good luck
