2CAN Plugin Released

[Peter Johnson]

Yes, it's blinking. Orange/off/orange/off from what I recall; I'll doublecheck in a couple hours when we're back in the lab.

We can connect to the 2CAN using the web interface and it can see the Jaguar on the CAN bus.

The same with us (blinking red while being able to see the 2CAN network on the browser). Noticing on trying to download code that the FRC_2CANPlugIn.out fails to load.

I suspect the problem is that FRC_UserProgram isn't imaged in when the cRIO is imaged for labview. Since the 2CAN plugin uses some of the library that's probably why its crashing. Darn, I thought i had removed all references to classes in the library (Nice catch peterjohnson). Expect an update soon.

Ours is working now (basically as soon as I turned on the robot). The 2CAN is still blinking orange/off/orange/off but the motor now drives via CAN! We fixed a couple of things very late in the day on Wednesday in both wiring (e.g. connecting the motor) and programming, so it's likely we didn't hit everything in testing we should have.

The key thing is indeed to order the StartupDlls correctly (for C++), at least until Omar gets the update out .

Hi - just curious, will the plugin source also be available on firstforge as with the BlackJag plugin? Hoping the answer is "yes" - great stuff for student team members to learn from, and also provide a way for the community to contribute.

Yes, it will be available soon. As soon as we update the plugin.

We are able to get the 2CAN to communicate via the cRIO with the jaguars. We are able to get the voltage bus and the temp. The 2CAn blinks green as long as we are in teleop. We cannot get the robot to move via the 2can. This occurs even if we set the CanJaguar to 1.0

Thanks for any help,

I'm now having an issue with the 2CAN plugin vs. camera dashboard. If the 2CANPlugin is loaded in StartupDlls, I get no camera at the dashboard (or camera data inside the UserProgram). If I delete the 2CANPlugin from the list of StartupDlls and reboot the cRIO, I get camera data at the dashboard. Any suggestions? I'm guessing there's some sort of networking contention issue between the UserProgram and the plugin? There is no CANJaguar code in the UserProgram, only camera dashboard/processing.
