Digilent adverises that USB-3114 is Matlab compliant. Does not work with Matlab

[PSLebow]

We just purchased a USB-3114 based upon the Digilent advertisement that it is Matlab compatible only to find that it is not. We now have to return to the vendor after spending 8 hours troubleshooting.

The MatLab DAQ Toolbox supports the USB-3114, but only asynchronous operations.  Please try the following code:

daqreset;
d = daqlist("mcc")
dq = daq("mcc")
addoutput(dq, "Board0", "Ao0", "Voltage")
for i=0:10
    write(dq,[i]);
    pause(1);
end
write(dq,[0]);
delete (dq);

The single-channel update rate is approximately 100 S/s and is system-dependent. For additional assistance, please contact Mathworks, the authors of the MCC support.

Thank you for the response.  I will try this routine. Is the 10 ms update time (100 S/s) time due to the Matlab limitation or MCC?  Why the 1 second pause?

[DAQman]

The USB-3114 throughput rate is 100 updates per second. I've circled the specification below in red.

OK, Thank you for the information. This does work.  I see the nomenclature is buried as a Matlab daq help topic "Getting started with MCC devices".  I didn't see any mention of that Matlab resource in any of the manuals. 

Is there a way to suppress the the Matlab warning "Added channel does not support clocked sampling:...." ?

100 Hz is sufficient for my purposes now.  Is there a higher rate DAC available with similar current output capabilities?  Can you recommend an output current buffer with no drifts or offsets?

Sorry, but we don't offer a higher-rated DAC with similar current output specs.
