Unable to see Digilent Analog Discovery 2 device in Analog Input Recorder app

Hi, I'm able to run successfully the code reported below, but I can't see my Analog Discovery 2 device in the Analog Input Recorder app (nor Analog Output Generator).

I can see the device in the Hardware Manager, but when I click on the device I get the following error message:

Many thanks in advance for any help or advice.

Regards

dev = daqlist

dev.DeviceInfo(5)

dq = daq("digilent")

addoutput(dq, "AD1", "1", "Voltage");
addoutput(dq, "AD1", "2", "Voltage");
ch_out = dq.Channels(1:2);
ch_out(1).Name = "AD1_1_out";
ch_out(2).Name = "AD1_2_out"

addinput(dq, "AD1", "1", "Voltage");

[data, startTime] = readwrite(dq, [output 2*output]);

Hi,

Actually having the same issue any suggestions why the Analog Input Recorder app doesn't see the AD2?

Thank you and Best Regards,

Hi,

As work arround I've used the code posted above.

I should mention that datestr is discouraged. Prefer datetime where possible.

For example,

dt = datetime("now","Format","dd-MMM-yyyy-HH-mm-ss")

dt = datetime
   12-Sep-2022-20-59-59

string(dt)

ans = "12-Sep-2022-20-59-59"
