I’m trying to use a Cedrus response box/pad with PsychoPy (1.85.2) on a Mac (OS 10.12.5).
I’ve confirmed with Cedrus that I’ve installed the right driver (according to Cedrus: VCP, rather than the D2xx driver; note that this seems to be different than what I first found in this post: Cedrus Responsebox doesn’t working )
I’ve confirmed with Cedrus (and a code from them), that in theory, PsychoPy can see my response box, but I still cannot get a simple routine to run:
I’ve tried a super simple “experiment” in PsychoPy’s builder with one routine (one text component and one Cedrus component). I’ve also tried another “experiment”, with a a second routine, where I copied the first routine and copied some code into the code component of the second routine: I tried to find and copy the start-routine and each-frame code from the button box part of the first routine into the code component of the second routine, since I read that this needs to be done for non-first Cedrus response components. (I’ve attached the code for this two-routine ‘experiment’ - perhaps I didn’t copy the right sections?)
In both cases, the program crashes and I get the following error message:
File XXX, line 126, in
if t >= 0.0 and buttonBox.status == NOT_STARTED:
File “/Applications/PsychoPy2.app/Contents/Resources/lib/python2.7/pyxid/pyxid_impl.py”, line 433, in getattr
return getattr(self._impl, attrname)
AttributeError: ‘ResponseDevice’ object has no attribute ‘status’
- Do I need to do any coding or add code to the code component for the first routine (if I have just one routine)? I assumed, as long as the response pad works, I can just plug the hardware in, select “Cedrus” as a response component and not have to use code.
- Any suggestions why I’m getting error messages in either case? Is PsychoPy not able to communicate with the box?
Thank you so much for any ideas, insights, or help!
