+// HelloWorld - simple demonstration of lcd
+// Created by Bill Perry 2019-11-23
+// bperrybap@opensource.billsworld.billandterrie.com
+//
+// This example code is unlicensed and is released into the public domain
+// ----------------------------------------------------------------------------
+// 
+// This sketch is for Noritake CU-U series displays like the
+// Noritake CU20025ECPB-U1J or CU20025ECPB-W1J
+// The Noritake CU20025ECPB display is a 20x2 line VFD display.
+// It is not a hd44780 display but is nearly fully compatible with a hd44780
+// display. The only real difference is the backlight control.
+// So while this device is supported by the hd44780 library,
+// the subclass will do its best to emulatate hd44780 functions and map
+// them to equivalent functionality when possible.
+//
+// Sketch prints "Hello, World!" on the lcd
+//
+// See below for configuring the Arduino pins used.
+//
+// Noritake CU-U series LCD module pins
+//  1 - LCD gnd
+//  2 - VCC (5v)
+//  3 - not connected
+//  4 - RS Register Select (rs) --- connect to Arduino pin
+//  5 - Read/Write ------ connect to gnd
+//  6 - Enable (en) ----- connect to Arduino pin
+//  7 - Data 0 (db0) ----
+//  8 - Data 1 (db1)     |-------- Not used in 4 bit mode
+//  9 - Data 2 (db2)     |
+// 10 - Data 3 (db3) ----
+// 11 - Data 4 (db4) ---- connect to Arduino pin
+// 12 - Data 5 (db5) ---- connect to Arduino pin
+// 13 - Data 6 (db6) ---- connect to Arduino pin
+// 14 - Data 7 (db7) ---- connect to Arduino pin

+// LiquidCrystal compability:
+// Since hd44780 is LiquidCrystal API compatible, most existing LiquidCrystal
+// sketches should work with hd44780 hd44780_NTCU20025ECPB_pinIO i/o class
+// once the includes are changed to use hd44780 and the lcd object constructor
+// is changed to use the hd44780_NTCU20025ECPB_pinIO class.

+// declare Arduino pins used for LCD functions

+// The parameters used by hd44780_NTCU20025ECPB_pinIO are the same as those
