SOFTWARE FOR TESTING

Figure 11.
Before running the software evaluation GUI, reset the ISEB by
pressing the SW2 button described in the Installing the Latest
ISEB Firmware section. Pressing SW2 removes any errors that
may be lingering due to an improper shutdown or disconnection
from the PC.
After completion of the software GUI installation routine, a
shortcut to launch the executable is added to the Program
Menu->Analog Devices – Inertial Sensor Eval. To launch the
evaluation GUI, click ADXL372 EVB GUI. A window similar
to the one shown in Figure 11 displays.
At this point, the functionality of the GUI deactivates completely.
Before testing any devices, the software GUI must be associated
with the previously installed hardware through the COM port.
See the PC Device Manager under the Ports (COM & LTP)
submenu to determine which COM port is assigned to the
Analog Devices inertial sensor evaluation system. Select this
COM port from the dropdown menu, and click Connect to
begin using the GUI.
After the COM port is connected, the full functionality of the
software evaluation GUI is available for use. The following
sections describe the purpose of each tab of the GUI. Exit the
GUI at any time by clicking Quit Program located in the lower
right side of the startup window.
Note: do not press the reset button (SW2) while the GUI is
running because it causes the ISEB and the software GUI to lose
sync and the evaluation system to malfunction. Additionally, if
for any reason, the ISEB board and the software evaluation GUI
do not appear to be properly communicating, perform the
following reset routine:
Close the software GUI by clicking Quit Program or by

REAL-TIME DATA TAB

The Real Time Data tab configures the inertial sensor
evaluation system and the
monitoring. The tab contains an oscilloscope-like interface to
view the output of the accelerometer and adjust the relevant
parameters, such as output data rate, bandwidth, filter, and
offset (see Figure 12).
The Low Noise checkbox toggles the LOW_NOISE bit of the
ADXL372. When low noise is activated, the device operates at
approximately 1/3 the normal noise level.
The LFP_DISABLE and HPF_DISABLE checkboxes toggle the
digital low-pass filter and digital high-pass filter bits of the
ADXL372. Activating the high- and low-pass filters disables the
internal digital filter of the ADXL372.
After configuration, begin real-time measurements by clicking
View Meas. To prevent software conflicts, clicking View Meas
causes many of the options and tabs to gray out or to disappear
until the Stop Meas button is clicked. The accelerometer output
data then begins to flow across the screen at the selected output
data rate.
Clicking View & Save Meas performs the same basic function
as View Meas except that it allows continuous data streaming to
the eleven .txt files. View & Save Meas is useful for recording
the response of the
The first .txt file is named and located by the user, and the other
ten .txt files are named based on the first .txt file and located in
the same folder.
