Open ericweiner opened 8 months ago

ericweiner commented 8 months ago

(error seen in the "fix-led-timeout" branch)

This is seen in the logs if the Basler camera is opened in the Pylon viewer, for example.

I dont think the same camera device is allowed to be open in Pylon viewer and LVP at the same time. It sounds like this is what you are experiencing?

ericweiner commented 8 months ago

Correct. I just wanted to fix the stack trace.
