Program Name    : ex2_rng_dices
Author          : Grant Phillips
Date Modified   : 08/02/2016
Compiler        : ARMmbed
Tested On       : STM32F4-Discovery

Description     : This example will demonstrate the STM32F4_RNG
                  class library to simulate the throw of two 
                  dices.

Requirements    : * STM32F4-Discovery Board
              
Circuit         : * A wire link between PB3 and pin6 of the SWD
                    connector (CN2) as explained in the SWV
                    examples section
