View And Record Data Panel - Analog Devices ADXRS800 User Manual

Evaluation Board User Guide

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 ADXRS800 data sheet.
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.

Figure 18. View and Record Data Panel
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 ADXRS800 data sheet.
This information is also recorded alongside 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 ADXRS800
gyroscope.
Adjusting the Supply Voltage
The ADXRS800 is 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 updates the voltage supplied to the
ADXRS800 satellite board. The Voltage Readback field
accurately displays the satellite supply voltage, which may be
slightly different from the value in the numeric control.
