fastrak

That's good you got it working with the GUI. What was the solution to that? I've made some small modifications to our fastrak sensor so it prints out a more useful error message. Email me at lashkari@worldviz.com and I will send you this new version. Hopefully this will help us track down the root of the problem.

i'm not sure. Perhaps a new computer. I installed the software and it started running right away.

I've sent you an email.

What advice would you give to someone who is trying to use the the fastrak dls over a USB connection? FTgui works just fine, but with the following code:

polhemus = viz.add('fastrak.dls')
polhemus.reset()
viz.tracker()

one of two things happen. Either the boring error message:
fastrak.dls Polhemus Fastrak v1.0
** ERROR: Failed to connect to Polhemus Fastrak over USB or COM1

Or the program simply exits instantly after opening a new window and giving the following output:
fastrak.dls Polhemus Fastrak v1.0
** NOTIFY: Connected to Fastrak over USB Connection
2 station(s) detected

Which to me seems like its working? This also happens on the testPolhemus script. I get the same results whether or not I include the "PORT_FASTRAK = 1" option or any variation thereof. How should I go about making this work?

Hi,

When we tested the Fastrak here we noticed that the USB drivers were very unstable. We reported these problems to Polhemus and they seem to have fixed it. Do you have the latest USB drivers? Also, are you using the fastrak.dls that comes with the latest version of Vizard (3.00.2007) ?
