2CAN Plugin Released

[Peter Johnson]

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.

Moving the 2CAN plugin after the UserProgram fixed this error and allowed the plugin to load.

The plugin needs to be loaded before the user program so that when the user program tries to use the CANJaguar class it won't get an error about the plugin not being loaded. The plugin definitely needs to not depend on WPILib entry-points.
