Compiler errors with PS3000a and MATLAB

Postby DavidMcKnight » Tue Aug 28, 2012 4:20 pm

Hi,

I've been trying to get a 3206B to talk with MATLAB, with not too much success. I modified a very simple script from elsewhere on this board and when I try to get it to run, the compiler complains and returns some errors.

I suspect that either a compiler setting has gone wrong, or there is some additional header file required and is missing, but if someone could give me some hints where to start to look that would be very much appreciated.

Code: Select all
    global data;

    loadlibrary('PS3000a.dll','ps3000aApi.h');
    if ~libisloaded('PS3000a')
        error('library PS3000a.dll or PS3000a.h not found') %check if the library is loaded
    end

    data.unithandle = 0;
    data.serial =[];

    [status_open, data.unithandle, data.serial] = calllib('PS3000a', 'ps3000aOpenUnit', data.unithandle, data.serial)

    status_close = calllib('PS3000a', 'ps3000aCloseUnit', data.unithandle);

    unloadlibrary('PS3000a');



The errors I get are:

Re: Compiler errors with PS3000a and MATLAB

Hi David,

It looks as though the compiler is not picking up the PicoStatus.h file - you might be able to confirm this by calling the 'libfunctionsview' function on the library and seeing the the return type for the 'status' value from the PS3000a dll function call.

Please refer to the following post in this forum:

http://www.picotech.com/support/topic10809.html

which uses the 'addheader' function; the alternative being to create your own protofile.

Hi Hitesh,

Thanks for looking at the problem. It wasn't the PicoStatus.h file (which I renamed and tried again and got a very different error message)

I've got the code to compile now, by changing the following things:
1) Commenting out line 54. It was typedef int64_t __int64; and came right after an #include stdint.h, which I think includes this.
2) Changing line 810 from u_int64_t to uint64_t

It now compiles, but when I try to run it MATLAB is unhappy about the dll file.

Error using loadlibrary (line 421)
There was an error loading the library "C:\Users\david.mcknight\Documents\MATLAB\WSL\PS3000a.dll"
C:\Users\david.mcknight\Documents\MATLAB\WSL\PS3000a.dll is not a valid Win32 application.

Caused by:
Error using loaddefinedlibrary
C:\Users\david.mcknight\Documents\MATLAB\WSL\PS3000a.dll is not a valid Win32 application.


I am wondering if it might be that my 64 bit version of MATLAB is having trouble with the driver running in 32bit compatibility mode. Might it be possible to get a DLL compiled as 64bit?

Hi David,

Thanks for your reply.

I hadn't realised you are using a 64-bit version of MATLAB. Unfortunately, we do not have any 64-bit drivers available. It is something that is being considered but there are no immediate plans for a 64-bit driver.

Update:

64-bit drivers are now available in the Software Development Kit.
