Define and preload data for device output, then start output generation to repeat in the background while MATLAB continues. d = daq("ni"); addoutput(d,"Dev1",1,"Voltage"); signalData = sin((1:1000)*2*pi/1000); preload(d,signalData') % Column of data for one channel start(d,"...
I am using a NI 9211 thermocouple DAQ module with the MATLAB Data Acquisition Toolbox to acquire temperature data. The module has a max of 4 channels with an aggregate sampling rate of 12Hz (12Hz/channel at one channel, 6Hz/channel for 2 chann...
the ni daq device must give a short output. I tried many ways to fulfill this function. Anyway, the problem is that I can't output other signals when the sine wave signal is outputting. Matlab warns the device has been reserved and the new output signal can't be start. Is there...
I'm using an MCC daq board USB-1208FS on Matlab-32bit r2013a. I am trying to test how the board works, and to do so I want to generate an analog output, and read it on an analog input channel. Here's the code (it should be correct, since this is what Measurement Computing su...
MATLAB Online에서 열기 Failures with supported versions of InstaCal may occur when the MCC DAQ Adaptor from one version of MATLAB is unintentionally used in another. To diagnose this situation, execute the following command at the MATLAB Command Pro...
Open in MATLAB Online Good afternoon, I'm having some trouble updating some old NI interfacing code (for a PCI-6115) to the new session based interface in 2011b. Here's the basic idea: I'd like to run my DAQ board like an oscilloscope, so ...
To simulate the hydraulic system, models from the Simscape/Fluids/Gas library of the Matlab Simulink environment were used, designed to simulate the flow of an ideal gas. The presented model uses the following gas dynamics simulation blocks: Fan (G), Pipe (G), and Fluids Local Restriction (...
I collect data with an NI Daq and then read in the csv to matlab for processing. the csv has ~10columns and the last column has string statements that say data 1 start...blank cells... data 1 end, data 2 start...blank cells... data 2 ...
