Error using Cedrus box in 226

[rkmaddox]

Trying to use the Cedrus box in 226. pyxid was not installed, so that was installed in Git Bash using pip install pyxid. Then when instantiating ExperimentController, response_device=cedrus was specified. Got the following error:

Traceback (most recent call last):
  File "C:\Users\labuser\Desktop\clds\CRM\exp_binaural.py", line 734, in <module>

    if port.upper().startswith('COM') and int(port[3:]) > 8:

port is an int with a value of 0, so there there was an error in pyxid's exception handling :-(

Cedrus box is connected via USB. From looking at the computers device manager, the USB-serial port should be 'COM3'.

Ideas?

You might need to install from git source. I committed some fixes to their repo and I'm not sure they've released since then.

Got it. Will try again. You'd think they would want to release the code that someone fixed for them...

Same error. Tried it again with newer version of pyxid (1.1 from git), installed thusly:

pip install git+https://github.com/cedrus-opensource/pyxid.git --upgrade

Hmm... I wonder if it's a Python2 vs 3 or Windows vs Linux thing. I don't think I tested all combinations, and you might be in one that I didn't. It should be possible to fix their code if you're up for it, or you can wait a couple of weeks and I can do it.

Might just buy a TDT ButtonBox.

That's certainly an option

[rkmaddox]

Eh, it's probably a simple fix. Have they been responsive at all? I can post an issue on their github page.

They were responsive in the sense that they merged my PR. Not sure how active they'd be in fixing it themselves, but it's worth a shot

[rkmaddox]

OK. I'll go that route first since travel is ramping up again.

Fixed a few weeks ago
