Interface to send triggers to BioSemi system.
BioSemiSerialPort - This is a class (function) that sends triggers to a BioSemi EEG system.
This function requires the purchase (or manufacture) of a USB to serial
hardware device.
sp = BioSemiSerialPort(); % open serial port
sp.testTriggers; % test pins 1-8
sp.sendTrigger(5); % send trigger '5' to eeg system
sp.findSerialPortName(); % for troubleshooting if not connecting properly
Note, if very fast (sub milisecond) serial port latency is important consider implementing this interface (pc only) to open serial port.
