3.6.1.1
Base Converter
To convert between binary, decimal, or hexadecimal, the base converter lets the user enter a value from
one base, and the GUI calculates the equivalent value for the other bases. All numeric up-down control
values are displayed as decimal values in the GUI, thus this tool can be effective for converter between
decimal and hexadecimal.
3.6.1.2
Time-of-Flight Converter
Because the TUSS44x0 device is intended for use in time-of-flight calculations, the time-of-flight converter
is used to compute a distance or round-trip time equivalent for the user input variable. Speed of sound is
assumed to be 343 m/s at room temperature by default. The speed of sound can change across
temperature and humidity. All conversions from time-of-flight to distance reference the speed of sound
value in this tool.
3.6.1.3
Datalog
The
Datalog
can be used to record and track GUI activity, as well as print device information such as error
status, diagnostic results, or ultrasonic measurement results. The contents of the
Datalog
section can be
saved to a new text file for each save button click. The text file is saved with the term
datalog
and a date-
time stamp in the "My Documents\Texas Instruments\TUSS Generation III\TUSS44x0" directory.
