Hi,
I'm trying to use a patriot tracker with vizcave. I'm comfortable enough with the maths and I have a functional patriot attached to my computer. I have used the PiMgr software and confirmed that the patriot is working and producing sensible data.
I am using a simple test script:
polhemus = viz.add('polhemus.dle')
patriot1 = polhemus.addPatriot()
viz.link(patriot1,viz.MainView)
(I typed that manually because I can't access the web from that computer right at this moment. The code was copied from your help docs, so any spelling mistakes above are not in the code)
I get the following feedback:
pohemus.dle Polhemus Extension
NOTIFY: Connected to Patriot over USB: 0 sensors detected
** ERROR: Failed to connect to a Patriot/Liberty: Device not found
** ERROR: Failed to create extension sensor with polhemus.dle
** ERROR: Link failed (source linkable is invalid)
If I turn the patriot off, then I no longer get the "NOTIFY: Connected to Patriot..." line.
I suspect my drivers, since the version of PDI.dll on my computer comes from 09/05/2007 (That's UK date format
) whereas the version of PDI.dll in the vizard bin folder is from 04/05/2011. I have no idea where to get drivers from - the polhemus site links to you!
Also, just to be sure - making sure that the sensor is in the right place, etc is only necessary when I'm trying to get good data out, right? If I'm doing that wrong, I should still get some data, even if it's garbage. Or am I missing something important?
If anyone has any ideas for how to update it, or a link to some updated drivers, then I'm all ears. If you need any data, I would be more than happy to provide it.
Thanks,
Steve
