Hi @plonskipe , thank you so much for your reply. By reading the application notes on biopac, I also came across the idea of TTL module which was used in E-Prime’s integration with biopac (Application Notes | BIOPAC). In the application note on biopac, they further explain how to send individual markers to biopac for different stimuli. You may find the sample codes used in the examples useful.
So far, I have tried iohub on psychopy3, but it did not work. I have decided to switch to inquisit instead of psychopy, but I have found several resources that may be helpful to you.
- somebody recommended the imhr package on python, it worked for parallel port in EEG-psychopy, so it may also work for psychopy-biopac.
- (Parallel Port Builder View - #3 by SabrinaSghirripa) some examples about communicating psychopy with EEG
Good luck with your studies!
