The simple RTX Kernel based example simulates the step-motor 
driver. Four LEDs are blinking simulating the activation of 
the four output driver stages:

- phase A
- phase B
- phase C
- phase D

This example simulates Half step driver mode and
CW rotation direction.

The Blinky program is available in different targets:
  NUC1xx Flash:  runs from Internal Flash located on chip
                 (used for production or target debugging)
