      It's not a difficult part to use, but it has so many features
the data sheet is 12 pages.  If you get a LED/LCD display catalog
from AND (415-347-9916) the data sheet is in the back, and they
even include wiring diagrams for the popular microcontrollers.
There's a character generator and cursor control in there, so
once you get it set up, it does most of the work.  But the
initialization ritual is complicated.
