Matlab DAQmxReadAnalogF64 taking too long (myDAQ dmm)

[rockofclay]

Hi there.

I am trying to use the daq.ni.NIDAQmx.DAQmxReadAnalogF64 function in matlab to read a resistance value from the myDAQ dmm port.

It's taking 1.8sec to do a read. Anyone know why this function is taking so long?

Cheers,

Paul

Does it function correctly in NI MAX? If it does, it could be something in your .m file or programming environment adding in the overhead. If it does not, that points to something with the driver, hardware, or signal you are reading.
