My best advice to you is to just begin playing around with it.Continuous data acquisition matlab The aim is to measure of quantity, the data and that will be stored in the cloud. After that, all you have to do is call one function from the ADLink API to output on the AUX lines. I think that's covered in the above example.

Most of your code in a MEX file is going to be devoted to the handover of variables from MATLAB-land to C-land. Just copy/paste the following into the Command Window,Įdit() Not a good learning example.īest thing to do is to start by looking at a Mathworks-provided MEX template.
And it probably wouldn't help you, it's a bit specific. I would give you a code example, but the code is the property of the lab I used to work for- I wouldn't feel right posting on the internet. > Has anyone tried to access the counters in ADLINK cards from Matlab and Data Acquisition Toolbox and if so would someone be willing to provide example code for that.īy counters, are you referring to the auxiliary lines? If so, yes, we've used them. So, to do this, you need basic knowledge of C++, and you need to study two things:ġ) MATLAB's MEX functions (for translating from MATLAB-land to C++-land)Ģ) ADLink's API - so you can know which ADLink functions will give you the output you want. Then, just fill in variables and functions according to your needs.Įssentially, all you are doing with this MEX wrapper is 1) translating MATLAB variables into C++ variables, and 2) feeding these new C++ variables into functions from the ADLink API. Go online, find a MEX tutorial and make a code template from the MEX tutorial. If you are going to take the MEX route, I have the following suggestion: This conditioning isn't exactly C++, as you would expect it. It's C++, but there's a lot of conditioning that must be done to translate variables from MATLAB-land into C++-land. MEX took a while to get down- it's sort of a hybrid of languages.
Instead, the MEX wrappers solved most if not all possible problems with timing. In my case, it was, so even if the DAQ toolbox worked properly with our card, I presume we still would have had issues using it for our application.

Since MATLAB is a software process, your timing could be off by tens of milliseconds (if timing is important to your application). Though, I would still be skeptical- if you were using the DIO card as I was, you would presumably depend on the speed of the card. It'd be interesting to see if ADLink does in fact release a new adapter in December that overcomes this limitation. It is implied by this advertisement that the main feature of the card- in my case, 32 high-speed DI/O - would be able to interact with the DAQ toolbox. Yes, ADLink certainly did misleadingly advertise when they advertised that the card could seamlessly integrate with MATLAB's DAQ toolbox.

Does anyone have any idea how to resolve this? I'm not finding anyone with similar issues on internet message boards. So when we attempt to create a digitalio object (using MATLAB's DAQ toolbox), MATLAB experiences a Segmentation Violation. However, it returns an empty array of object constructors.
When we check, in MATLAB, to see that the card is recognized, we get the following,ĪdaptorDllName: 'C:\ADLINK\DAQ-MTLB\DLL\mwADLINK.dll'Ĭlearly, MATLAB recognizes the ADLink adapter.
#Daq matlab 2009 manual#
We have installed this library, according to the user manual supplied by ADLink. ADLink has released a MATLAB library + adaptor that allows you to use ADLink DAQ cards with MATLAB's DAQ toolbox. We have an ADLink PCI-7300A Rev B high-speed digital I/O card. This might be a somewhat specific question- but if anyone has any experience with using the DAQ toolbox with an ADLink DAQ card, any feedback/experience would be appreciated.
