// Project: Nokia5110 - Controlling a NK5110 display from an NXP LPC1768
// File: NOKIA_5110.h
// Author: Chris Yan
// Created: January, 2012
// Revised: January, 2014
//  Desc: Commands, fonts, and class for using a
//      Nokia 5110 LCD via the Phillips 8554 LCD driver.
//  Typical Usage: User must fill the LcdPins struct with the pinout used to control the LCD and
//      instantiate the NokiaLcd class - passing the created LcdPins struct to the constructor.
//      The class function NokiaLcd::InitLcd may then be called to reset and start the LCD driver.
//      A simple 6x6 font (6x8 in LCD space and ~5x5 character space) is included to facilitate 
//      the NokiaLcd::DrawChar( char character ) function, which will copy the character 8 bits 
//      at a time for 6 clock cycles.
//                 Commands may be sent to the LCD via the NokiaLcd::SendFunction(char cmd) 
//      function, but be aware that certain commands require the Function Set register's H-value
//      to be either 1 or 0, depending on the command. This class does not check to see whether
//      the H-value is of proper status. The Function Set register /may/ be changed via the 
//      NokiaLcd::SendFunction(char cmd), but the code uses this internally and expects that
//      most function registers have not been changed by the user.
//      Example:
//          #include "mbed.h"
//          #include "NOKIA_5110.h"
//          int main() {
//              LcdPins myLcdPins = { p11, NC, p13, p10, p8, p9 };
//              NokiaLcd myLcd( myLcdPins );    // SPI is started here (8-bits, mode 1)
//              myLcd.InitLcd();                // LCD is reset and DDRAM is cleared
//              myLcd.TestLcd( 0xAA );          // Draws a vertical pattern where every other pixel is on 
//              wait(10);                       
//              myLcd.ShutdownLcd();            // Clears the LCD's DDRAM and powers it down via CMD_FS_POWER_DOWN_MODE, H=0
//              while(1)
//              {   };
//          }
