The
Log a Single Entry
command causes logging to start, collect one single entry, and
immediately stop again. This function is not available when logging is already running.
Click
Clear Log
to discard any data that has already been collected. If there is data in memory,
which has not been saved to disk, this function displays a prompt asking to verify it is OK to discard
the data. If the log is running when this function is clicked, the log continues running after the
existing data is discarded.
Click
Save Log
to save the collected log data to a csv file. This stops the logging function, if it is
active, and displays a file dialog box to specify where to store the logged data. The default file
name is described in the
Log Status and Control Information
section, but the file name may be
changed if desired.
4.2.3 Help Menu
The Help menu contains a single function: About.
Figure 6. Help Menu

OK
button to close this window and continue.

System Level Controls
Immediately below the top menu bar there are checkboxes used to control the system level
functions of the TSL2540 device.
The
Power-On
checkbox controls the PON function of the TSL2540. When this box is checked, the
power is on and the device can operate. When this box is unchecked, the power is off and the
device does not operate (The control registers can still be written, but the device does not function).
The
ALS Enable
checkbox controls the AEN function of the TSL2540. When this box is checked,
the device collects and report ALS data as programmed. When this box is unchecked, the ALS
functions do not operate.
