Patriot and Vizard
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 |
