Use Matlab with USB-6009

[hohenjm]

Hello,

I have a project to. For this project I have to send signal from Matlab to the USB-6009. After the signal go trough a filter and come back to the USB-6009, so I also have to recieve informations to Matlab from the USB-6009. Is there anybody who know the Matlab instructions in order to do it?

Thank you so much!!!!

Hey hohenjm,

I think the following tutorial will help you: An Introduction to NI-DAQmx Tools for The Mathworks, Inc. MATLAB® Software

Thank You.

I already have this programm. I tried to creat channels but I can't. Do you know how to do this with matlab?

Thank you.

hohenjm,
why do you want to create channels?
In MAX the USB device is recognized as "devX" (where X represents a number)
In Matlab you only have to use one of the delivered functions (DAQ_DEMO_Browser) of the DAQmx Tools for Matlab and to specify a device and a channel.
For example:
[data, time, initial_time, timed_out] = AcqNUpdates('dev3/ai0', -10, 10, 100, 1000, 10)

Whereas dev3/ai0 indicates the USB 6008 device (information from MAX -> Measurement and Automation Explorer)

Thank you very much to answer. For my study I have to generate and send signals in real time. An other solution is to use the Matlab Data Acquisition Toolbox 2.8,

with this solution I think that I must create channels so I would like to know how to do this.

Thanks for any help.

I am so sorry, but in this point I cannot give you support.
Either contact directly Mathworks or have a look on the following links:

Data Acquisition Toolbox
User's Guide
Examples

Another option to get access directly in Simulink to our HW would be to compile the m files (with some modifications for sure) with the s-function builder and to include it via a user function block in Simulink

Hi Folks,

I got a problem with the USB 6009 NI when I connect a PID Controller to an Analog Output in the Simulink.

I would like to know how do I use the PID Controller without change the Time Domain to Discrete-Time, because I need to use a Continuous-Time.

Thank in Advantage.

Best Regards

Can you Tell me how i make simulink/matlab 2012b to recognize the ni usb 6009 

where matlab recognize usb6009 in matlab but in simulink give me it recognize to winsound microphone

can any body replay for me

Hi Pedro,

Have you solved this problem yet? I have the same problem as you but could not find any solutions in any forums.

Can you help me?

Thank you a lot.
