Hi,

As to the data sheets, I had a headache with the Hitachi part because Hitachi's
own datasheet was incorrect. I assume it has been corrected now......It was to
do with the "display off" in 4 bit mode.........(I hate it when the datasheet is
wrong).

I have attached a stripped down version of something I wrote to familiarize
myself with the display operating in 4 bit mode.  It is passionately brain
dead code (we write in C  for real projects).

It was developed for a display using the KS0066U.  You can find the
datasheet for that at
http://www.usa.samsungsemi.com/products/summary/charlcd/KS0066U.htm
or reference the Hitachi datasheet for the HD44780 at
http://semiconductor.hitachi.com/products/product_abstract.cfm?p_id=36

I would recommend reading these if you are reading the LCD manufacturer's
data sheets.
