// LCDiSpeed - LCD Interface Speed test
// ----------------------------------------------------------------------------
// This sketch is a wrapper sketch for the hd44780 library example LCDiSpeed.
// 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/LCDiSpeed/LCDiSpeed.ino
// From IDE:
// [File]->Examples-> hd44780/hd44780examples/LCDiSpeed

#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

// 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.
