I’m currently switching from using SuperLab to Psychopy and am having some problems in regards to sending event markers to BIOPAC (MP150). Essentially, I want to send an event marker right before the start of a video. On SuperLab, I could do so by creating an event “Digital Output” which I could see as a raised line on one of the digital channels on AcqKnowledge.
Is there a way to do this on Psychopy? As per the API, I tried to implement pyserial:
ser = serial.Serial (‘COM1’)
But I am not sure what to actually “write” in order to get that raised line on AcqKnowledge (nor am I sure I am doing any of this correctly…) If anyone has any insight on this, that would be greatly appreciated!
Edit: I am using Psychopy 1.84 on a Windows 7
