Hello,

I have been trying to synchronize NI frame grabber (NI PCIe -1430) and NI-DAQ(6221) using Matlab 64-bit version . I know that there is a similar example (source code) written in 32-bit version Matlab software like the following link:

http://www.mathworks.com/help/imaq/examples/synchronizing-a-national-instruments-frame-grabber-and-data-acquisition-card.html.

I am looking for an example (source code) written in 64-bit version Matlab commends because 32-bit Matlab commends became obsolete in 64-bit version.

Thank you so much for your help in advance.

Hello Jong Kim,

64- bit MATLAB supports Session based Interface for Data Acquisition. In session based interface we create a session and all communication is handled using that session object.

The Synchronizing a National Instruments Frame Grabber And Data Acquisition Card example you mentioned in the question uses legacy based functions and the corresponding Session based Interface functions can be found in the documentation link below :

Acquire Data using Session Based Interface

An example on how to do data acquisition using session based interface example in MATLAB can be found in the documentation link below:

Acquire Analog Input Data

Hope this helps.

Thanks
