Dear friends.
I´ve been having problems in my control application using LabView+DAQ NI-USB 6215.
In general, I need to read a analog input, filter this input by a LMS FIR filter and then write this filtered signal in analog output port.
The problem is that my output signal is okay in the window graph (Labview), but wrong in the output port of DAQ. To be more exact, the frequency of my generated signal is wrong, smallest than must be.
I'm setting the input port with the continuous samples mode, at a rate of 2500 Hz, with 1 sample to read for loop iteration. The output port has been configured with an on demand mode.
Somebody knows how to fix it? Maybe the the frequency of my signals were corrupted by the loop iteration time?
