Generate Digital Output Using Decimal Data Across Multiple Lines

This example shows how to convert decimal data and output to two lines on an NI 6255.

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 port0onDev1.

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

Convert the decimal number 2 to a binary vector, and generate that digital output value on the two lines.

write(d,decimalToBinaryVector(2))
