I am trying to use a serial port (via a USB-serial adapter) to send event markers from PsychoPy to COBI Studio (an fNIRS data acquisition software). I’ve achieved it via the Code component, but was really hoping to get it working with the Parallel Port Out component (following Jon’s response in this Google groups thread so it would be easier for a larger number of potential users (staff and students), but can’t get it working. My guess is that I am not specifying the port correctly… I’ve tried all the hex possibilities for COM4 (as well as just ‘COM4’) to no avail.
Any help would be greatly appreciated. In particular, how do I find the correct port name and what format does PsychoPy (v1.9.3 on Windows with Python 3.7.1) require this to be?
Thanks in advance!
