Hello,
I want to send triggers to a Brain Amp MR system by Brain Products, specifically to the Recorder program, via Parallel Port. However, I did not find the parallel port component in the current version of PsychoPy i’m using (1.78). Is there any way to do this through the builder in this version? or maybe by coding?
Any solutions would be greatly appreciated,
Ofir
Hi Ofir,
Version 1.78 is now nearly 4 years old, which makes it very difficult for people here to offer useful support. Are you able to update to the latest version?
Hi Michael,
I completed updating to the recent version successfully (version number 1.84.2), and attempted to send triggers by using the parallel port component module – but this does not work.
Currently, the experiment is running on windows 7.
At first, I received this error: "p_port = parallel.ParallelPort(address=u‘0x0378‘)
AttributeError: ‘module’ object has no attribute ‘ParallelPort’ ".
Subsequently, I inserted the “inpout32.dll” file in the experiment’s folder, as suggested in a previous post about this error (python - PsychoPy sending triggers on 64bit OS - Stack Overflow). Afterwards the experiment managed to work again, but I did not get triggers in my recorder. Next, I installed the LPT Test Utility as suggested in the above-mentioned post as well, and succeeded to get triggers in my recorder from this program, but not from PsychoPy. Hence, it seems that the triggers do not work specifically while using PsychoPy.
Please see a picture of the component’s properties attached.
Looking forward for a solution,
Thanks,
Ofir
