// LCDcharset - Display LCD character set for hd44780 hd44780_NTCUUserial i/o class
|
|
// ----------------------------------------------------------------------------
|
|
// This sketch is a wrapper sketch for the hd44780 library example LCDcharset.
|
|
// Note:
|
|
// This is not a normal sketch and should not be used as model or example
|
|
// of hd44780 library sketches.
|
|
// This sketch is simple wrapper that declares the needed lcd object for the
|
|
// hd44780 library sketch.
|
|
// It is provided as a convenient way to run a pre-configured sketch for
|
|
// the i/o class.
|
|
// The source code for this sketch lives in hd44780 examples:
|
|
// hd44780/examples/hd44780examples/LCDcharset/LCDcharset.ino
|
|
// From IDE:
|
|
// [File]->Examples-> hd44780/hd44780examples/LCDcharset
|
|

|
#include <SPI.h> // optional, include to use h/w spi
|
|
#include <hd44780.h> // main hd44780 header
|
|
#include <hd44780ioClass/hd44780_NTCUUserial.h> // Noritake CU-U serial i/o class header
|
|
|
|
// define the LCD geometry
|
|
#define LCD_COLS 16
|
|
#define LCD_ROWS 2
|
|
|
|
// 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
|
|
// 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.
