This documentation is a tutorial for the BCI2000 software (version 2.0). It will cover every step I had to take for my bachelor's project (”A physiologically driven computer interface using EMG”), including the download of the source code, building of the code, and installation. The creation of an acquisition module will not be covered, since I used Biosemi2ADC and most hardware has an acquisition module for BCI2000 ready for use. If anything is unclear, you can always find more information on the BCI2000 wiki or the forum.
