Digital input using DataAcquisition interface MATLAB 2020a

2 views (last 30 days)
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!
