Connect Neurosky Mindwave in ATTENTION

I using code :

function read_ATTENTION

TG_DATA_ATTENTION = 2;

Matlab code to read attention using Mindwave mobile

%Clear Screen

clc;

%Clear Variables

clear all;

%Close figures

close all;

%Preallocate buffer

data_att = zeros(1,256);

%Comport Selection

portnum1 = 14;

%COM Port #

comPortName1 = sprintf('\\\\.\\COM%d', portnum1);

% Baud rate for use with TG_Connect() and TG_SetBaudrate().

TG_BAUD_115200 = 115200;

% Data format for use with TG_Connect() and TG_SetDataFormat().

TG_STREAM_PACKETS = 0;

% Data type that can be requested from TG_GetValue().

TG_DATA_ATTENTION = 2;

%load thinkgear dll

loadlibrary('Thinkgear.dll');

%To display in Command Window

fprintf('Thinkgear.dll loaded\n');

%get dll version

dllVersion = calllib('Thinkgear', 'TG_GetDriverVersion');

%To display in command window

fprintf('ThinkGear DLL version: %d\n', dllVersion );

% Get a connection ID handle to ThinkGear

connectionId1 = calllib('Thinkgear', 'TG_GetNewConnectionId');

if ( connectionId1 < 0 )

error( sprintf( 'ERROR: TG_GetNewConnectionId() returned %d.\n', connectionId1 ) );

end;

% Attempt to connect the connection ID handle to serial port "COM3"

errCode = calllib('Thinkgear', 'TG_Connect', connectionId1,comPortName1,TG_BAUD_115200,

TG_STREAM_PACKETS);

if ( errCode < 0 )

error( sprintf( 'ERROR: TG_Connect() returned %d.\n', errCode ) );

end

fprintf( 'Connected. Reading Packets...\n' );

i=0;

j=0;

%To display in Command Window

disp('Reading Brainwaves');

figure;

while i < 20

if (calllib('Thinkgear','TG_ReadPackets',connectionId1,1) == 1) %if a packet was read...

if (calllib('Thinkgear','TG_GetValueStatus',connectionId1,TG_DATA_ATTENTION ) ~= 0)

j = j + 1;

i = i + 1;

%Read attention Valus from thinkgear packets

data_att(j) = calllib('Thinkgear','TG_GetValue',connectionId1,TG_DATA_ATTENTION );

%To display in Command Window

disp(data_att(j));

%Plot Graph

plot(data_att);

title('Attention');

%Delay to display graph

pause(1);

end

end

end

%To display in Command Window

disp('Loop Completed')

%Release the comm port

calllib('Thinkgear', 'TG_FreeConnection', connectionId1 );

but the wrong code command window shows up:

Error: File: Connect.m Line: 36 Column: 88

Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched

delimiters.

means line 36 is:

errCode = calllib('Thinkgear', 'TG_Connect', connectionId1,comPortName1,TG_BAUD_115200,

TG_STREAM_PACKETS);

can you help me to solve this ? thankyou

Try change line 36 with :

errCode = calllib('Thinkgear', 'TG_SetStreamLog', connectionId1, 'streamLog.txt' );

Tsalsabilla. Could you pass me your mail, please? He needed help connecting mindwave to matlab. mail. [e-mail]

[SITI SURYANA BINTI MOHD FAUZI]

I used the same code as above an already try to change it, but it still more error.
