Hi everyone,
Quick question to sanity-check our setup:
We’re running an EEG experiment in PsychoPy (Coder) with a g.tec g.HIamp. Right now we’re using LSL/software markers, but we’re worried about latency/jitter for ERP work.
We’re thinking of switching to hardware triggers: sending codes from PsychoPy via a PCIe DB25 parallel port using win.callOnFlip(...), into the g.HIamp DIGITAL IN, and validating timing with a photodiode.
Is this the recommended approach in the PsychoPy community for reliable event timing with g.HIamp?
