Picoscope executable

Postby Renaat » Thu May 16, 2013 5:25 pm


Below i have some code to read my signal into matlab.
After this i do some operations. This works all but now i want to make an executable so i can use it on a pc without maltab. When i make the executable i always get a problem. Always at loadlibrary. The error is can't find lcc.exe.
i already installed MRC (Matlab runtime compiler) but still the same problem.
After some search work i found that i have to make a prototype file or something like that.
Got somebody experience with that with the picoscope and can help me further ?

Thx in advance

Hi Renaat,

You would have generated your prototype file when executing the line:

Code: Select all
loadlibrary 'PS5000.dll' 'ps5000Api.h' addheader 'picoStatus.h' mfilename 'PS5000MFile';

I've not compiled an executable before from MATLAB but you might want to change the line to:

Code: Select all
loadlibrary 'PS5000.dll' 'PS5000MFile';

Hope this helps.
