Program Name    : ex1_LM6029ACW_HelloWorld
Author          : Grant Phillips
Date Modified   : 08/02/2016
Compiler        : ARMmbed
Tested On       : STM32F4-Discovery

Description     : Example program that writes "Hello World!" in
                  normal mode and then inverted to a LM6029ACW 
                  graphics LCD.    

Requirements    : * STM32F4-Discovery Board
              
Circuit         : * The LM6029ACW is connected as follows:
                    (see the LM6029ACW datasheet for a complete
                    description of each pin).
                    Vss (LM6029ACW pin 1)           -   GND
                    Vdd (LM6029ACW pin 2)           -   3.3V
                    DB7 (pin3)                      -   PC15
                    DB6 (pin4)                      -   PC14
                    DB5 (pin5)                      -   PC13
                    DB4 (pin6)                      -   PC11
                    DB3 (pin7)                      -   PC9
                    DB2 (pin8)                      -   PC8
                    DB1 (pin9)                      -   PC6
                    DB0 (pin10)                     -   PC2
                    /RD (pin11)                     -   PD2
                    /WR (pin12)                     -   PD3
                    RS (pin13)                      -   PD6
                    /RES (pin14)                    -   PE2
                    /CS (pin15)                     -   PD7
                    BLA (pin16)                     -   PB_7 with a transistor/FET circuit (or 3.3V if it is not required to switch the backlight on and off)
