Getting the Network Tables to work with an off loaded vision system

[Ken P.]

We got a Kangaroo as well. We don't have enough resources to support a quick turn port to RasPi2 or another CPU family. It would be really cool, but cost reduction or simplification is not on the menu this year. Are you using GRIP, OpenCV or RoboRealm? We have a MS 3000 HD and an Axis 1013 camera, so that's another choice to be made.
In order to get the network tables from the Kangaroo to the RoboRio you need to use the USB port. We can use USB, Ethernet, RS232 or I2C. (There are device and host USB ports on the RoboRio.) I am trying to figure out which channel to use. I am leaning towards I2C. Anyone have any experiences to share?
I2C normal mode will transfer approx. 12.5K bytes per second, so that is over kill for the network tables. I am nervous about doing anything Ethernet based due to the strange network tricks they pull during the contests.
