Hello, I am trying to send triggers to BrainVision through a parallel port. My experiment consists of many different images flashing briefly onscreen one after another. I am hoping to send triggers whenever a new image flashes on screen. It would be most convenient if I were able to send a differen…

After a long time of attempting to figure out this issue, I finally have resolved it, so I am posting it here for anyone who is having a similar problem! For reference, my stimuli consist of face, pareidolia, and object images. To align your triggers with your stimuli, I inserted the following code …

Parallel port code no longer working since update to Psychopy 2022.1.1 Coding

Hello all, We recently updated the psychopy version in our EEG lab to version 2022.1.1 from a much older version (I’m not sure which but at least 3 years old). Everything mostly works fine but all of my code interacting with parallel ports no longer works. For example, if I use: parallel.setPortAddress(address = 0xCEF8) then try to use the parallel port I get the error message: ‘RuntimeError: Port address must be set using setPortAddres’. If I check the parallel port via print(parallel.PORT) th…

Sending triggers via parallel port to eego software Builder

OS (e.g. Win10): Win 7 PsychoPy version (e.g. 1.84.x): PsychoPy2 **Standard Standalone? y **What are you trying to achieve?: First of all, thanks in advance and apologies for bringing up a common issue again but I’ve been searching for answers all day and not been able to solve this issue. I’m trying to get PsychoPy to send triggers to the eego EEG software to see when certain images are displayed. I’ve followed threads such as this: Cannot send a signal via ParallelPort using PsychoPy on…

Parallel module and class Coding

Hello, I have written a script using Psychopy’s coder and now I need to send triggers through a parallel port to our data collection equipment. I found this article that explains how to use Psychopy’s Builder to communicate via a parallel port. I also found the documentation to the psychopy.parallel module described in this article. Unfortunately, the article does not provide access to the source code of the module and there is no documentation about the class methods and attributes besides th…

Parallell Port component doesn't send triggers to EEG recording device Builder

Hello everyone, I’m trying to send markers to an EEG recording device (I’m using BrainVision Recorder) with the help of the Parallel Port component of the builder. I tried to make sure that I follow the instructions for the component (Communicating via a Parallel Port — PsychoPy v2023.2.3). I’ve attached screenshots of my try of rebuilding the test experiment suggested in the Parallel Port component instructions and of the folder with my experiment file and the driver files needed in case I ma…

Differentiating Parallel Port Signals for Each Video in a Loop Builder

Hello, I am currently working on an experiment where I have a routine with a loop that displays three different video clips. Each time the routine resumes, it cycles through these videos. Alongside this, I am using a parallel port that sends out a signal with the value “9”. However, for my data analysis, I need each video clip to be associated with a unique signal. (10, 11 …) I am having trouble figuring out how to modify the parallel port signal so that it sends a different value each time a…
