I am running an EEG experiment for which I would like to send event triggers to the EEG recording computer.
For stimulus presentation, I am using a laptop that does not have a parallel port (and if possible, we don’t want to have intervening adaptors etc.), but VGA, HDMI, USB and ethernet interfaces. The EEG system receives digital inputs via a Dual Link DVI-I interface.
Now the most straightforward solution would be to send triggers from Psychopy via HDMI or VGA output pins to the DVI-I input pins with a regular HDMI/VGA to DVI-I adaptor and a HDMI or VGA cable. Is there any way to control the HDMI or VGA pins explicitly in my Psychopy code, just like I can control the parallel port?
Thanks for your help!
