generate signals on both analog and digital channels

this example shows how to generate signals when the dataacquisition 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.
