int main ( void  )

Light & proximity sensor demo application entry.

After initializing the Xplained platform and sensor boards, this application attaches descriptors to the ambient light and proximity sensor devices on an Xplained inertial sensor board. The sensor data, which is formatted and printed via printf() after being read, can be viewed with a serial terminal application on a machine attached to the USB interface on the Xplained board.
