/*
 * This library is designed to make it easy for anyone to get the Nokia 5110 display 3.3V module up and running without delay
 * It provides a convenient interface for printing single characters or strings of characters and vertical bar graphs, all at various magnifications.
 * It is free to use and modify. I accept NO liability for malfunctions or damage caused by this software
 * I hope it is useful to the community and am open to suggestions for improvement.
 *
 *
 * ---Example code---
 * 
 * #include "mbed.h"
 * #include "N_5110_Display.h"
 *
 * N_5110_Display Display( p5, p6, p7, p8, p9, p10 );
 *
 * int main()
 * {
 *     Display.setCharPos( 0, 0 );              //x pos = 0, y pos = 0
 *     Display.printString( 'Bar', 2, 3 );      //output string with char width 2, char height 3
 *
 *     Display.setCharPos( 0, 3 );              //x pos = 0, y pos = 3
 *     Display.printString( 'Graph', 2, 3 );    //output string with char width 2, char height 3
 *
 *     Display.setCharPos( 11, 0 );             //x pos = 11, y pos = 0 .... X pos is 11 to allow for a bar graph with width 3
 *     Display.VertBarGraph( 40, 3, 6 );        //generate a vertical bar graph 40% full with width = 3 char, height = 6 char
 *
 *     while (1)
 *     {
 *
 *     }
 * }
 *
 *
 * ---End of example code
