Digital input using DataAcquisition interface MATLAB 2020a

I noticed that MATLAB no longer recommends some functions, like addDigitalChannel, in version 2020a onwards. Currently, I am creating an app to acquire signal from several NI DAQ-cards. However, I get an error I can't solve:

"Check for missing argument or incorrect argument data type in call to function 'addinput'".

The small example code below gives me that same error. I have looked at the documentation and my 'addinput'-line seems correct.

Has any of you experienced this issue? It seems like I am missing something obvious.

Thanks in advance.

daqreset
method = 1;
if method == 0 % Old method <2020a
    d = daq.getDevices;
    sCheck = daq.createSession('ni');
    chCheck = addDigitalChannel(sCheck,'SimDev1', ...
    'Port0/Line0:2','InputOnly');

    [data,~] = inputSingleScan(sCheck)

else
    d = daqlist("ni")
    addinput(d,"SimDev1",...
         "port0/line0","Digital");

end

Hi,

Can you try using 'daq' instead of 'daqlist'.

d = daq("ni");
addinput(d,"SimDev1",...
         "port0/line0","Digital");

Hope this helps!
