Sending triggers from Response Switch through parallel port to psychopy
Posted: Thu Sep 21, 2023 8:09 pm
Hello
I'm tying to implement an experiment that requires the use of two buttons "Response Switches" which go to the AC-Box (port ERGO1). AC-Box in turn is connected through fiber optic to the Analog Input Box. This AIB is connected by a parallel port to the display computer and through USB to an EEG computer. On the EEG computer, on ActiveView software I'm fully able to detect psychopy-evoked LTP triggers and button-produced triggers.
The thing is I would like to be able to read the LTP triggers produced by the button on the psychopy computer to log responses and give feedback.
I've tried several options, including writing code that checks if I'm receiving LTP signals through any pin (2-13 nor 15).
I also tried using this solution https://discourse.psychopy.org/t/issue- ... box/9759/2
that consisted on manually changing pin7 of the parallel port.
I don't really know what else to try.
Best,
Gonzalo
