+// HelloWorld - simple demonstration of lcd
+// Created by Bill Perry 2016-07-02
+// bperrybap@opensource.billsworld.billandterrie.com
+//
+// This example code is unlicensed and is released into the public domain
+// ----------------------------------------------------------------------------
+// 
+// This sketch is for the Nortake CU165ECBP-T2J display
+//
+// Sketch prints "Hello, World!" on the LCD
+//
+// If initialization of the LCD fails and the arduino supports a built in LED,
+// the sketch will simply blink the built in LED.
+//
+// Datasheet can be found here:
+//	http://www.blog.zapro.dk/wp-content/CU165.pdf
+// Full datasheet/release notes:
+//	http://www.blog.zapro.dk/wp-content/CU165ECPB_T2J_specification.pdf
+//
+// The device uses SPI for communication.
+// Pinout:
+// 1 Vcc
+// 2 GND
+// 3 /CS  (SS)   - Digital Pin 10 on Uno
+// 4 CLK  (SCK)  - Digital Pin 13 on Uno
+// 5 DATA (MOSI) - Digital Pin 11 on Uno
+//
+// ----------------------------------------------------------------------------
+// LiquidCrystal compability:
+// Since hd44780 is LiquidCrystal API compatible, most existing LiquidCrystal
+// sketches should work with hd44780 hd44780_NTCU165ECPB i/o class once the
+// includes are changed to use hd44780 and the lcd object constructor is
+// changed to use the hd44780_I2CNTCU165ECPB i/o class/
+
+#include <SPI.h> // optional, include to use h/w spi
+#include <hd44780.h>
+#include <hd44780ioClass/hd44780_NTCU165ECPB.h> // include io class header
+
+// constructor parameters:
+// lcd([cs], [clock, data])
+// If no parameters, then library will use SS, SCK, and MOSI pins
+// If cs parameter specified, then use it for chip select then SCK and MOSI
+// If <SPI.h> is included and clock & data pins match h/w SPI pins SCK and MOSI,
+//	 h/w spi will be used
+// If h/w spi is not possible, then the code will fall back to bit banging.
+//
+// NOTE:
+//  - Leonardo h/w is "stupid" and does not bring out SS
+//     (it only drives an LED)
+//  - Leonardo does not bring SPI signals to female headers,
+//     they are only on 6 pin ISP header.
+//  - ESP8266 is does not use naked constants for digital pin numbers 
+//
+//
+// To work around these pin issues in this sketch,
+// Leonardo will use uno digital pins for SPI h/w which means it will
+// will not use h/w spi. All the other boards will use the h/w SPI pins.
+// Consult board pinout diagram to see where SS, SCK, and MOSI are available.
+//

+	// Special Note:
+	// =============
+	// Since this device uses a write only SPI interface, there is no way for
+	// the library/sketch to know if the device is present or if there is any
+	// type of issue communicating with the device.
+	// So while begin() returns a status as to whether it was successful,
+	// the library will never report a failure since it has no way of detecting
+	// a communication or initialization issue.
+
+	// initialize LCD with number of columns and rows: 
+	lcd.begin(LCD_COLS, LCD_ROWS);
+	
+	// Print a message to the LCD
+	lcd.print("Hello, World!");
