The
operation select
dropdown allows device operating mode to be switched between power down and
continuous capture modes. The oneshot mode of the device is not exposed by the EVM GUI.
The
mode select
drop down changes the device gain range setting mode. The device supports automatic gain
control (ACG), which is the recommended mode setting for most use cases, or the gain range of the device can
be selected manually using this dropdown.
The device supports two
conversion times
: 100ms and 800ms, which can be selected using the respective
dropdown.
The
display sample count
selects how many samples are displayed on the x-axis of the plot.
Save to file
The
set save to file name
check box allows the data captured in the GUI to be dumped to a CSV file. Clicking
this check box will display a windows file selector screen. Select the directory to store the CSV and set the name
for the CSV. After clicking save the GUI will wait for you to click the
start capture
button to start saving data and
susequently it will wait for a click on the
stop capture
button to copy all the data into the indicated CSV file. When
capturing data with save enabled, the GUI will initially dump the data to temporary .npy files. After clicking
stop
capture
this data is written over to the CSV file and .npy files removed.
Mean, Std, and the Blue Slider
There is a blue slider on the lux plot shown on the right side of the plot in the figure. Mean and Std columns in
the table where capture data is displayed are calculated from only the data within the blue slider. Left-clicking on
the middle of this slider and dragging moves the slider. Left-clicking on the edge of either side of the slider and
dragging will adjust the size of the slider. This allows the mean and standard deviation of the distance, phase,
and amplitude to be computed for any continuous portion of the displayed data. If capture is running this data
updates in real-time along with the data in the Live column.
Scripts Window
When Latte is launched the GUI window appears front and center. However, there is a second window that is
minimized at launch. This is the scripts window and exposes some more advanced features of the Latte platform
that will be described below.
