I have a Matlab application for use with the Picoscope 3205A. When running it from the command line of Matlab everything works fine, however when I create executables using the Matlab compiler I can no longer connect to the Picoscope. I am using the same computer the whole time, there is no difference in installed drivers or hardware setup.
I am using the latest versions of Matlab and compiler, R2015a. I looked at the link you provided, we are already using the prototype and thunk files provided in the Picoscope SDK for Matlab.
Are the ps3000a.dll, picoipp.dll and ps3000aWrap.dll files in a location on the Windows PATH environment variable so that your executable can locate them?
They are included as part of the compiled Matlab executable, and we have also tried putting them on the Windows PATH env variable. No luck with either. From the console output, it appears to be finding everything and breaking on something when it loads ps3000aWrap_thunk_pcwin64. Just before that it looks like it had loaded ps3000_think_pcwin64 without any problems.
