Control Signal going to Application Module

Hi,

I was exploring signal processing and application modules, however, I can't find the code that links them together. Where can I find the code that sends the control signal to the application module?

Please advise,
Thanks.

Nadoona,

The BCI2000 framework provides all appropriate communication in the system, including sending control signals to the application. Unless it is your personal interest, you should never have to inspect or modify the BCI2000 framework. All you should have to do is to focus on operation of the particular filter you would like to modify.

Thanks for your reply.

I do not really want to change the BCI2000 framework. I just want to know where is the control signal set and then used by the application, so I can set the control signal to whatever value I want in my own filter. Then, I would like to use that value passed fromt the signal processing module in my application.

Please help.

Thanks.

Nadoona,

The control signal that finally makes it to the application is defined in the Process() function of the last filter in the filter chain of the Signal Processing Module. Does this make sense?
