Author          : Grant Phillips
Date Modified   : 03/05/2016
Compiler        : ARMmbed
Tested On       : STM32F4-Discovery

Description     : Example program that writes "Hello World!" to 
                  a HD44780-based text LCD. 

Requirements    : * STM32F4-Discovery Board
              
Circuit         : * The HD44780-based text LCD is connected 
                    as follows:
                    Vss (LCD pin 1)             -   GND
                    Vdd (LCD pin 2)             -   3.3V
                    Vee (pin3)                  -   Contrast circuit
                    RS  (pin4)                  -   PD8
                    RW  (pin5)                  -   GND
                    E   (pin6)                  -   PD10
                    DB0 (pin7)                  -   
                    DB1 (pin8)                  -   
                    DB2 (pin9)                  -   
                    DB3 (pin10)                 -   
                    DB4 (pin11)                 -   PD12
                    DB5 (pin12)                 -   PD13
                    DB6 (pin13)                 -   PD14
                    DB7 (pin14)                 -   PD15
