Controlling Logging Parameters
6-29
start(vid)
The object executes an immediate trigger and begins acquiring frames of data. The
start function returns control to the command line immediately but the object
continues logging the data to the memory buffer. After logging the specified number
of frames, the object stops running.

Check how many frames have been acquired — To determine how many frames
the object has acquired and how many frames are available in the memory buffer,
check the value of the FramesAcquired and FramesAvailable properties.
vid.FramesAcquired
ans =
15
vid.FramesAvailable
ans =
15
The object updates the value of these properties continuously as it acquires frames
of data. The following figure illustrates how the object puts acquired frames in the
memory buffer as the acquisition progresses.
