VPixx hardware support

[tomwallis]

Hi Psychopy forum,

I’m a current psychtoolbox user who’s dabbled in PsychoPy previously. After once more getting fed up with Matlab I’m planning to dip back into the PsychoPy world for future research.

My question: is there hardware support for VPixx Technologies hardware yet? It doesn’t appear on the hardware page of the API, so I’m guessing not. I asked about this some time ago on the old psychopy forum. Specifically, it would be good to be able to access the high-bitdepth / scanning backlight modes of VIEWPixx displays.

Any update or pointer to what would need to happen for this to exist would be appreciated.

Cheers

Tom

To be honest I never got around to playing with this but VPixx themselves created a Python library (I believe, maybe just for win32?) and other users have certainly used VPixx combined with PsychoPy (@rebeccajsharman?).

It would be great to see support built better into PsychoPy but it just isn’t where the majority of support requests come from

I have used VPixx with PsychoPy, I didn’t do anything fancy with the functionality, but I had a responsePixx working quite happily. The VPixx library for Python is very similar to the Matlab version. When I used it it wasn’t amazingly user friendly as there was a definite lack of documentation. I think they did quite a big update a couple of years ago though, so it may well be better now.

Ok, thanks Jon and Rebecca!

@rebeccajsharman A collaborator is asking me to put together a barebones experiment using VPixx - would you be willing to dig out and share the experiment (or relevant snippets from) that had responsePixx working? Thanks in advance!

Hot topic:

VPIXX hardware class?

I’m hoping to switch our lab computer over to use PsychoPy from PTB. We use a VPIXX Inc ViewPixx 3D monitor. As previously discussed, it should be relatively simple to integrate psychopy code and the VPIXX python API (to control screen properties) within the same script by just importing both. What I’d like to know from the developers is whether it would make sense to create a new ViewPixx class within psychopy.hardware similar to the bits++ class. This might be nice to unify the API between ha…

Hi Erik,

It’s been quite a few years since I wrote this, so I make no promises about it’s compatibility with the current versions of anything and I don’t currently have access to a VPixx set up so I can’t test anything. However, assuming it all works as it used to this should contain the basics, or at least enough to get you started (probably). I hope it helps!

Best,

Becky
