Python Error

[John Schmotzer]

Has anyone seen the following error working with the python library in Linux?

Exception in thread Thread-1 (most likely raised during interpreter shutdown):

Traceback (most recent call last):

  File "/usr/lib/python2.7/threading.py", line 552, in __bootstrap_inner

  File "/usr/local/lib/python2.7/dist-packages/openxc/sources/base.py", line 195, in run

Hi John,

Maybe USB isn't detected or USB backend isn't installed? What python command were you using?

eh I can see it when I do openxc-dashboard so its detecting the VI - and the backend is "installed"......

openxc-control write --bus 1 --id 0x580 --data 0x8FFFFFFF80FFFFFF

Do simpler (e.g. openxc-control version) commands work for you? 

One thought I had is if you don't have raw_writeable turned on in the VI config, are you getting a timeout and an empty response? So I'm suggesting a simpler test first.

Regards,

Eric

Good question, simpler tests seem to work, I'll look at it again when I get a chance but the version one worked last I remember.

Raw writable is enabled, and I'm connected via USB.
