Hello oogieoogieful,
Someone else might be able to help you get things working, but our experience is that we have not had a customer be able to utilize our supplied 32-bit Matlab example on a 64-bit version of Matlab. We do not have a version of 64-bit Matlab in our shop and so have been unable to attempt to work through the incompatibilities. It does appear that one would have to go through quite a bit of effort to call a 32-bit DLL from 64-bit Matlab.
If you are interested, we have fully updated our SA device APIs. There are now 32 and 64 bit versions of the API that get installed when you download the latest version of our Spike spectrum analyzer software. http://www.shnavloginupdates250428.kinsta.cloud/Spike. We recommend all new developers target these new APIs. They come with documentation as well to get you going. We do not currently provide Matlab interfaces to them, but if you are adept at C/Matlab programming you should be able to find enough information to call our 64-bit DLL from Matlab. The new APIs do have a different interface than the old ones, so there will be a learning curve which may not be acceptable if you are already familiar with the older APIs.
Let me know if you have any follow up questions.
Regards,
A.J.
