The Data Log frame, in the bottom center of the Main screen contains a Start / Stop button, as shown in
the following figure. That button enables or disables, respectively, the logging of sensor data to a file on
the PC’s hard disc.
When the Start button is clicked, the user is prompted for the output filename and location. Because the
file is written in the ASCII format, a .txt filename extension should be used. The data is written at a fixed
rate of 10 Hz, irrespective of the sampling rate selected for the eCompass.
The file format is below. The column headings after Time Stamp match the data fields in the main screen.
The columns and example data are as follows:
Time when this line was recorded and written.
