REAL TIME DATA TAB

The Real Time Data tab configures the inertial sensor evaluation
system and the ADXRS290 for real-time angular velocity
monitoring. This tab contains an oscilloscope-like interface that
shows the output of the gyroscope and allows you to adjust the
relevant parameters, such as high-pass filter and low-pass filter (see
Figure 16).
After configuration is complete, click the View Meas button to
begin real-time measurement. To prevent software conflicts,
many of the options and tabs gray out or disappear until you
click the Stop Meas button. The gyroscope output data then
begins to flow across the screen.
The View & Save Meas button performs the same basic function as
the View Meas button; however, it allows you to continuously
stream the data to 11 text files, which is useful for recording the
response of the device even during long term events. The first
text file is named and located by you, the other 10 text files are
named based on the first text file and are located in the same
folder.
Figure 16. Real Time Data Tab
For example, if you name the first text file ADXRS290Test.txt in
the pop-up dialog box and save it on your desktop, the other
10 text files, which are named ADXRS290Test_1.txt,
ADXRS290Test_2.txt, ... ADXRS290Test_10.txt, are built
automatically on your desktop. When ADXRS290Test.txt saves
the 64k samples, the next 64k sample sets are stored in the files
ADXRS290Test_1.txt through ADXRS290Test_9.txt. In the
last file, ADXRS290Test_10.txt, the data is saved continuously
even if its size is bigger than the 64k samples. If you test the
sensor in short time, and the samples are smaller than 64k, the
files without any data automatically delete when you click the
Stop Meas button.
Each text file created contains a header with the date, the time,
and the X and Y axes angular velocity data (in degree/second),
which are aligned in tab-delimited columns.
