Hi, I tried your driver but I still obtain the same behavior. I think the problem is the Labiew_DLL.dll dynamic library or the Biosemi2 module (a mistake in the C++ code). That is my conclusion, because with Actiview software I obtain the behavior we hope. Finally, do you suggest to used the g.Usbam...

Hi, everyone Changing the Labview_DLL.dll with another version of this library, I'm able to close the Biosemi 2 module in asynchrone mode. However, I obtain the same result as before (constant signals 0 valued or strongly negatives). May be the error comes from the Labview_DLL.dll. Does someone have...

Thank Grev, You was right. I forgot to install the Biosemi driver. However, I'm still not able to acquire data from Biosemi 2. First, on the Biosemi2Client.cpp source file, I have to call the mpfCLOSE_DRIVER(mDevice) handler (at line 294) instead of mpfCLOSE_DRIVER_ASYNC(mDevice), otherwise a segmen...

Biosemi Active 2 source module

Hi everyone, Currently, I'm trying to configure BCI 2000 in order to acquire EEGs from the Biosemi Active 2 device. Through BCI 2000 launcher, I ran the Biosemi source module with DummySignalProcessing (as signal processing module) and FeedbackDemo (as application module). On the source view, I defi...

Hi, Juergen

I have found my mistake. I must send the following message :
-> 'Running 0\n'
I forgot the '\n' characters at the end of the message.

Best,

Martin Miguel

Hi, Juergen Finally, I think I'm sending a wrong message to BCI 2000 in order to set the 'Running' state variable to 0. I tried several solution : - 'SET STATE Running 0' - 'Running 0' - 'Running 1 0 0 0' - 'SET STATE Running 1 0 0 0' - 'Running 1 0 2 1' - 'SET STATE Running 1 0 2 1' But all these s...

Hi, Juergen : There is another thing that I note. Even if I send a message "TOTO" that generate the same behavior when BCI 2000 receive it. May be the problem is the UDP connection. Do know how should I initialize the UDP connection with Java for sending packets to BCI 2000 ? Thank you very much for...

Hi, Juergen Thank you for your last suggestion. I tried to implement it. However, I have a little problem. From my java application, I run the following commands prompt : > {path_to_BCI2000}\prog\SignalGenerator.exe > {path_to_BCI2000}\prog\DummySignalProcessing.exe > {path_to_BCI2000}\prog\Feedback...

BCI 2000 Client/Server communication

Dear Juergen, Thanks to you I have a lot of new ideas for my BCI application. However, I would like to know the following things : 1. Is it possible to start BCI 2000 operator module without starting any Application module ? Because, in my Java application, brain stimulations are managed by another ...

BCI2000 Client/Server communications

Hi everyone! I would like to develop a BCI with Java and using BCI 2000 as acquisition system. Currently, I'm trying to understand how can we transmit acquired brain signals by BCI 2000 to a Java application (with TCP or UDP). If I well understand, the BCI 2000 web page mention that we can do it thr...
