The plugin that's installed with the FRC image is very old (early 2010). Requesting firmware version does not work with that plugin.

Is it possible that the serial plugin is also old? In that event we will try to load the plugin we used in December and report back

]EDIT[
Nope still broken.

I would like to know if the 2CAN is indeed working. If it is we will switch temporarily

After updating to the latest 2CAN plugin the 2CAN is communicating with the jags and the cRIO fine, but we still get UncleanStatusException when we try to initialize.

The serial plugin is not old. When the v25 Image was created, I put the wrong 2CAN plugin in the image. That will be fixed in the update.

This is an issue with the Java implementation. The C++ and LabVIEW CANJaguar implementations are not affected.

Glad to read this. Team 20's controls team spent the greater portion of this weekend figuring this out for ourselves. Once we reimaged the CRIO back to last year's image and loaded the old Netbeans plugins and had them work flawlessly, we called it a day. Thanks for your work!

Hey Joe,
when could we expect the update to be pushed through. Our team is eager to run our chassis with can asap so drivers can practice.

We here at team 3309 have created a tutorial for our workaround to get CAN working before the official fix is released. Go to our wiki page http://goo.gl/ytxaL to see the tutorial.

It is posted now! You can download it at FIRST Forge or you can use the automatic update in NetBeans.

Re: Updated CAN Jaguar Issue

Thanks for getting it fixed!
But now I am having a new problem.When I tried to call getSpeed(), it would constantly return 0.0. I looked in the javadoc and it said "returns speed of the motor in RPM based on the configured feedback." How do I configure it so I get a real speed value?

A call like:

Code:

myJag.setSpeedReference(CANJaguar.SpeedReference.kQuadEncoder);

Re: Updated CAN Jaguar Issue

Thanks, I set a position reference but I guess I forgot to set a speed reference. This is the first year that we're using CAN so we still have a lot to learn.
