Inertial sensor data visualizer demo application entry.

This application uses a serial connection to transmit sensor data. The data is formatted for use by the Atmel Data Visualizer application running on a remote host.

Upon entry, the hardware (including processor and sensor board) are initialized, and the sensor interfaces are established. The application then transmits a series of special data stream configuration packets, which tell the remote application the number, type, and labels for data streams that will subsequently be used.

After this initialization, the application enters a continuous loop in which it periodically samples the sensors that are defined and sends the obtained data values to the remote host in stream data packets. Each type of sensor measurement uses an interval counter to determine how often the measurement should be performed and transmitted.

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.
