Generate Signals on Both Analog and Digital Channels

This example shows how to generate signals when the DataAcquisition object contains both analog and digital channels.

Discover NI™ devices connected to your system and find the ID for the NI 6255.

d = daqlist("ni")

dev =

  3×4 table

    DeviceID                Description                  Model             DeviceInfo       
    ________    ___________________________________    __________    _______________________

     "Dev1"     "National Instruments(TM) USB-6255"    "USB-6255"    [1×1 daq.ni.DeviceInfo]
     "Dev2"     "National Instruments(TM) USB-6363"    "USB-6363"    [1×1 daq.ni.DeviceInfo]

Create a DataAcquisition and add two digital output lines from port 0 on Dev1.

d = daq("ni");
addoutput(d,"Dev1","Port0/Line0:1","Digital")

Add an analog output channel from Dev1, then view all channels.

addoutput(d,'Dev1',0,'Voltage')
d.Channels

Output a single scan of data on both the digital and analog channels.
