TUSS44x0 EVM for Ultrasonic Sensors User's Guide
The default start-up GUI view is of the block diagram page, which provides a high-level perspective of the
internal blocks and configurable features of the device. This perspective is intended to present which user-
controlled settings are most important for proper device operation. A more detailed settings perspective
can be found on the
Data Monitor
page. When the settings have been properly adjusted for the specific
driver mode and transducer combination, navigate to the
Data Monitor
page. The
Data Monitor
page
displays the ultrasonic echo data dump and measurement results the user must optimize for a particular
sensor configuration, environment, and target combination. The user can immediately click the
START
button from the
Run Options
group box to determine if the entire EVM is working. All pages and tabs of
the GUI features are described in the sections that follow.
The GUI is partitioned into three panels: left, center, and right. The left and right panels are secondary
panels for utilities, supporting tools, calculators, and background functions. The center panel displays and
allows the user to update all device related pages.

Device Status
The GUI monitors the device status by periodically reading back the device status registers. All status
error bits must read a given state for the device to be in the normal or working state, and is indicated by a
blue back color. If any of the status bits read an irregular state, an operational fault exists or the register
map is corrupt, and the device may not function properly, and is indicated by a red back color. The Device
Status automatically updates after each time of flight command measurement. To manually update the
Device Status fields at any time, click the refresh button in the bottom left corner.
