First steps to realtime EEG and BCI on Raspberry Pi

2 Replies

I just compiled the FieldTrip realtime EEG interface on the Raspberry Pi. The code compiled out of the box, not a single line of code needed to be changed thanks to the existing cross-platform support for the old Apple PPC-G4 and the Neuromag HPUX-RISC MEG system. Streaming data to and from the FieldTrip buffer over TCP/IP works like a charm.

I’ll add my binaries for the Raspberry Pi to the regular FieldTrip release.

The next step will be to compile some of the EEG acquisition drivers, e.g. for OpenEEG and BrainVision.

Eventually it would be nice to also get BCI2000 to work on the Pi. According to Juergen large parts of BCI2000v3 should compile on the ARM… I look forward to gving it a try.

FieldTrip is a Matlab toolbox for MEG/EEG analysis that is being developed by the F.C. Donders Centre in Nijmegen, the Netherlands. The toolbox includes algorithms for simple and complex analysis of MEG and EEG data, such as time-frequency analysis, sourceanalysis and non-parametric statistial testing. It contains high-level functions that you can use to construct your own analysis protocol in Matlab. It supports various file formats, and new formats can be added easily.

FieldTrip has its own website where you can download the code and documentation.
