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
daqvendorlist
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");
addinput(dq, "AD1", "2", "Voltage");
ch_in = dq.Channels(3:4);
ch_in(1).Name = "AD1_1_in";
ch_in(2).Name = "AD1_2_in"
rate = 300e3;
dq.Rate = rate;
% Specify a 10 Hz sine wave for 1 second.
f = 10;
totalduration = 1;
n = totalduration * rate;
t = (1:n)/rate;
output = sin(2*pi*f*t)';
[data, startTime] = readwrite(dq, [output 2*output]);
plot(data.Time, data.AD1_1_in, data.Time, data.AD1_2_in);
xlabel('Time (s)');
ylabel('Voltage (V)');

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,
no progress from my side, still unable to use Analog Input Recorder app.
As work arround I've used the code posted above.
Regards,

Ran in:
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"
