Updated CAN Jaguar Issue

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.

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);

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.

Or if you used the installation over the network, just update.

Thanks for fixing this. We have a multi-team design review tonight so we wont get to try this out until tomorrow but I am glad we can finally switch back from PWM control.

Awesome, thanks! I will definitely try it out today.

I had a chance to try it out yesterday and today, and it looks like the timeout issue has been fixed! Jag control seems to be rock solid. Thanks guys!
