Hello!

I want to run some of the tasks I developed on psychopy with LFP recordings. I was wondering if is possible to just use the offline version (python code) and add LFP markers to psychopy programs. Our device get markers through parallel ports. Does someone knows how to work this out?

Thank you so much!
