Nothing Special / testF100R6

simple tests for STM32F100R6 microcontroller with dedicated library

Dependencies:   mbed-STM32F100R6

To compile a program with this library, use NUCLEO-F103RB as the target name. !

Change only one "#if" to "#if 1" to select the desired test. Others "#if" must be "#if 0".
