ScansQueued
Indicate number of scans queued for output
Description
In the session-based interface, the ScansQueued
property
displays the number of scans queued for output queueOutputData
.
The ScansQueued
property increases when you successfully
call queueOutputData
. The ScansQueued
property
decreases when the hardware reports that it has successfully output
data.
Values
This read-only value is based on the number of scans queued.
Example
Display Scans Queued
Queue some output data to an analog output channel and examine the session properties to see how many scans are queued.
Create a session and add an analog output channel.
s = daq.createSession('ni'); ch = addAnalogOutputChannel(s,'Dev1','ao1','voltage');
Queue some output data and call the ScansQueued
property to
see number of data queued.
s.queueOutputData(linspace(-1,1,1000)'); s.ScansQueued
s.ScansQueued
ans = 1000
