-LCD4Bit v0.1 16/Oct/2006 neillzero http://abstractplain.net
-
-What is this?
-An arduino library for comms with HD44780-compatible LCD, in 4-bit mode (saves pins)
-
-Sources:
-- The original "LiquidCrystal" 8-bit library and tutorial
-    http://www.arduino.cc/en/uploads/Tutorial/LiquidCrystal.zip
-    http://www.arduino.cc/en/Tutorial/LCDLibrary
-- DEM 16216 datasheet http://www.maplin.co.uk/Media/PDFs/N27AZ.pdf
-- Massimo's suggested 4-bit code (I took initialization from here) http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1144924220/8
-See also:
-- glasspusher's code (probably more correct): http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1160586800/0#0
-
-Tested only with a DEM 16216 (maplin "N27AZ" - http://www.maplin.co.uk/Search.aspx?criteria=N27AZ)
-If you use this successfully, consider feeding back to the arduino wiki with a note of which LCD it worked on.
-
-Usage:
-see the examples folder of this library distribution.

-//Improvements ------------------------------------------------
