int main ( void  )

Inertial sensor demo application entry.

After initializing the Xplained platform and sensor boards, this application attaches descriptors to the accelerometer, gyroscope, and compass 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.

Initialize sensor data output streams for Atmel Data Visualizer.

This routine initializes the data streams used in this application for the Atmel Data Visualizer (ADV) tool. First, a start-of-configuration packet is constructed and sent. Next, each data stream is described with a stream descriptor packet and either one or three field descriptor packets (depending on how many data fields are used to report a single set of data from that device). After all streams and data fields have been described, an end-of-configuration packet is sent.
