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
ans = Index Type Device Channel Measurement Type Range Name _____ _____ ______ _____________ _____________________ __________________ __________________ 1 "dio" "Dev1" "port0/line0" "OutputOnly" "n/a" "Dev1_port0/line0" 2 "dio" "Dev1" "port0/line1" "OutputOnly" "n/a" "Dev1_port0/line1" 3 "ao" "Dev1" "ao0" "Voltage (SingleEnd)" "-10 to +10 Volts" "Dev1_ao0"
Output a single scan of data on both the digital and analog channels.
