EEG Emotiv - Matlab - matlab

Question

Im trying to run the eeglogger or the emotiv Toolbox to record some samples of the EEG Emotiv, but it always show some errors:
Error in EmotivEEG (line 73)
[notfound,warnings] = loadlibrary('edk.dll','edk.h');
%#ok
and If I follow some instructions of forums I can get this:
Warning:
'EE_COGNITIV}EE_EmotivSuite_t;typedefenumEE_ExpressivAlgo_enum{EXP_NEUTRAL=0x0001'
exceeds MATLAB's maximum name length of 63 characters and has been
truncated to
'EE_COGNITIV}EE_EmotivSuite_t;typedefenumEE_ExpressivAlgo_enum{E'.
In edk_proto at 11 In loadlibrary at 379 In eeglogger at 84 Error loading library intermediate output follows. The actual error is
at the end of this output.

Caused by:

I put all files needed in the same folder
Anyone know how can I be able to use emotiv with matlab? and why everyone has the same problems but no confirmed solution?
thanks

Answer 1

Ok as i wrote before and got punished for it, i had the same problem, but i solve it, first of all are you using matlab 32 bits?? otherwise it wont work anything, im using matlab 32 bit 2013, you also need visual studio 32 bit compiler 2010 or older,you need to have all the .dll files on the same folder as well as the edk.h file and set the proper c compiler suing mex -setup, i use the files share by akshaybabloo to acces the emotiv and its working so far.
Note: You must have a research edition Emotiv Epoc otherwise you wont be able to access EEG raw data .
