TTL triggering

mkcyeungmkcyeung Hong Kong

Hi,

I am new to OpenBCI, and so far I am happy about the recently purchased Cyton board.

I plan to use the Cyton board in a psychological experiment. To ensure precise timing of events on the EEG, the OpenBCI system needs to receive a TTL trigger from a stimulus presentation computer (triggered inside the E-Prime software). I think the use of a USB to serial UART cable, as well as some wiring and firmware changes may do the trick, but I am not sure.

Is there any practical advice as to what I can do to set up the communication? @wjcroft @retiutut @evaesteban

Many thanks!

Best,
Michael
