Program Name    : ex1_rng_GenerateRandomNumbers
Author          : Grant Phillips
Date Modified   : 08/02/2016
Compiler        : ARMmbed
Tested On       : STM32F4-Discovery

Description     : A program to demonstrate the use of the true
                  Random Number Generator (RNG) on STM32F4xxx 
                  devices through the use of the STM32F_RNG class 
                  library.  This example will simply display the
                  32-bit random generated numbers.

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