#Nokia 5510 GLCD control code

This code is a direct port of the public domain Arduino source code to control the Nokia 5510 LCDs that are available from Sparkfun. It was converted and tested with a C18 toolchain in MPLABX against a PIC18F2550, but should be pretty easy to convert to XC8 -- in fact, I suspect that you just need to add it to your project. Your PIC will need an SPI port connected to the MISO and MOSI pins on the LCD, ##Usage

Add both glcd.h and glcd.c to your project, then in your main.c

#include "glcd.h"
#include <spi.h>

#define _LCDSelect LATAbits.LATA3 //These can be any output pins, but these are the ones that I chose.
#define _LCDReset LATAbits.LATA4
#define _LCDData LATAbits.LATA5

Then in void main()

void main()
{
	TRISA=0;
	
	LCDInit();
	LCDClear();
	LCDString(myString, strlen(myString));
}

Do not drive the backlight with 5V. It will smoke. However, the backlight on the LCD seems to be happy with direct drive from the 3.3V regulator.
