Generate stimuli with the OpenBCI board

Hello ! I'm waiting for my Cyton board... and I want to generate some stimuli based on the attention levels (turn on leds or generate a "beep" for example)... One approach is to process the signal with a software for example OpenVibe and return a value and send it to the board to generate the stimuli (i dont know if it is possible) or  the other approach is: i was wondering if there is a library for processing the signal on the Cyton board itself (as if openBCI was an arduino).

I hope you can help me

    Hugo, hi.

    Checkout Chip's blog,


    Easiest way to do this is with signal processing on the laptop, then send "commands" out a separate serial port to an arduino, which can do arbitrary digital output.

    Even easier is to use a VPL such as OpenViBE, BioEra, Bioexplorer, BrainBay, LabVIEW, neuromore, etc. that generates the feedback directly on the laptop. This is how neurofeedback programs work.

    While you can program the firmware on the Cyton for any function, it takes considerably more effort than feedback from your signal processing app. And digital level output from the Cyton also has the potential to overwhelm the very sensitive microvolt EEG signals.
