// Date: 21 Nov 2004
//
// Usage : Include 3310.c in the main project file, include delay.h and delay.c
// in the main file, define the PIC pins to be used in this file, in the main
// code file call init_nokia(); to initialise the LCD
// nokia_gotoxy(0,0);
// nokia_printchar('D');
// nokia_printmessage("hello can you really read this?");
