BrainBay DSP Environment Update for Ganglion & Cyton

BrainBay-design

BrainBay is an open source Visual Programming Language (VPL) that allows Digital Signal Processing (DSP) elements to be connected together graphically to construct a signal processing and biofeedback pipeline.

Chris Veigl, author of BrainBay has just released the latest 2.4 version of BrainBay that includes support for OpenBCI Ganglion (both dongles: BLED112 and CSR). Previous versions have supported Cyton, so all OpenBCI platforms / interfaces are available to create your own designs. BrainBay has a unique ability to provide a framework for neurofeedback / biofeedback applications.

The main site for BrainBay is here, and it’s Github page here. For related forum posts, see this forum thread and this forum search.

We want to thank Chris very much for adding this capability and also AJ Keller (of OpenBCI and Neurosity) who created the Hub mechanism / process that allows BrainBay to access the Ganglion stream.

Chris advises:

“For Ganglion the BrainBay integration needs the OpenBCI Hub bridge for interfacing with the Ganglion. To achieve this, the path to OpenBCI Hub.exe must be specified in the BrainBay menu Options / Application Settings. The recommended way is to install the OpenBCI GUI for first operation of the Ganglion, and then providing the path of the Hub exe to BrainBay in App Settings panel. Typically: C:\Program Files\OpenBCI_GUI\data\OpenBCIHub\OpenBCIHub.exe. This panel also has a Sampling Rate box which defaults to 256 Hz. That should be changed to 200 when using Ganglion.”
