Figure 19. View and Record Data Panel
The
View and Record Data
panel is the primary panel for
interacting with the device. The drop-down box, located
beneath the graph, contains the following three options:
Do Nothing
(the default option)
View Gyro Signals
Record Gyro Signals
Clicking
View Gyro Signals
obtains the rateout signal, filtered
self-test, raw self-test, and quadrature information from the
device and plots all four signals simultaneously. As indicated by
the GUI, the data rate at which this information is obtained is
500 Hz ± 5%. The data rate is hardware controlled so that it
remains constant regardless of the priority and processor load
assigned to the software GUI by the operating system. For more
information on the significance of the plotted signals, see the
ADXRS450
and
ADXRS453
data sheets.
Clicking
Record Gyro Signals
performs the same basic
function as
View Gyro Signals
; however, it allows you to
continuously stream the data to a .txt file. This is useful for
recording the response of the part during short term events of
less than ~2 minutes. This also ensures that the resulting data
file is manageable across most data analysis software packages.
You can perform the record functionality indefinitely.
Secondary information that is transmitted along with the
plotted signals is graphically represented. This includes the fault
register, sequence bits, status bits, and sensor module bits.
This information is described in detail in the
ADXRS450
and
ADXRS453
data sheets. This information is also recorded along
with the plotted signals when you select
Record Gyro Signals
.
Additional functionality on this panel includes the ability to
change the supply voltage, read the device ID and serial
number, read the individual memory registers, and perform
offset adjustments to zero out any residual offset. These
options encompass the majority of the functionality of the
ADXRS450
/
ADXRS453
gyroscope.
Adjusting the Supply Voltage
The
ADXRS450
/
ADXRS453
are designed to operate over the
full voltage range of 3.3 V to 5 V (±5%). The device is designed
to offer equivalent performance regardless of the voltage level
available in the application. The numeric control allows you to
adjust the voltage to reflect the voltage level available in your
application. Clicking the
Set
button in the
Supply Voltage
Adjust
box updates the voltage supplied to the
ADXRS450
/
ADXRS453
satellite board. The
Voltage Readback
box accu-
rately displays the satellite supply voltage, which may be slightly
different from the value in the numeric control.
