Updated CAN Jaguar Issue

We tried putting the initialization in a loop as suggested, but still got the error.

When you used the 2CAN did you load the 2CAN plugin instead of the serial can plugin?

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

Be sure to use the latest 2CAN plugin from our site....

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

Nope still broken.

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.

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.

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.

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

Thanks so much for working on this problem over the weekend. Team 346 appreciates it.

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.

I anticipate it will be out later today or possibly tomorrow.

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

For those less aware . . .
http://firstforge.wpi.edu/sf/frs/do/viewRelease/projects.wpilib/frs.wpilib_java_update_for_2011_frc.wpilib_java_fr c_2011_update_ve_1

is where the update is. Unload all of the older nbm files and load the 5 new ones.

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?

Have you configured a reference sensor?

A call like:

myJag.setSpeedReference(CANJaguar.SpeedReference.kQuadEncoder);
