outputSingleScan

(Not recommended) Generate single scan on all output channels

This session object function is not recommended. Use DataAcquisition object functions instead. See Version History.

Syntax

outputSingleScan(s,data)

Description

outputSingleScan(s,data) outputs a single scan of data on one or more analog output channels.

Examples

Analog Output

Output a single scan on two analog output voltage channels

Create a session and add two analog output channels.

s = daq.createSession('ni');
addAnalogOutputChannel(s,'cDAQ1Mod2',0:1,'Voltage');

Create an output value and output a single scan for each channel added.

outputSingleScan(s,[1.5 4]);

Digital Output

Output one value on each of two lines on a digital channel

Create a session and add two digital channels from port 0 that measures output only:

s = daq.createSession('ni');
addDigitalChannel(s,'dev1','Port0/Line0:1','OutputOnly')

Output one value each on the two lines:

outputSingleScan(s,[0 1])

Input Arguments

s — Data acquisition session

session object

Data acquisition session, specified as a session object. Create the session object using daq.createSession. Use the data acquisition session for acquisition and generation operations. Create one session per vendor and use that vendor session to perform all data acquisition operations.

data — Data to output

doubles

Data to output, represented as a 1-by-n matrix of doubles, where n is the number of output channels in the session.

Version History

Introduced in R2010b

R2020a: session object interface is not recommended

Use of this function with a session object is not recommended. To access a data acquisition device, use a DataAcquisition object with its functions and properties instead.
