you can connect the Pi to RoboRio on serial line that will be simplest,
other solutions may be I2C or Ethernet but I think best and easiest will be serial (not usb serial)

3322 will be using UART to communicate between the two. I will post our code here in a week or two when we get around to writing it.

Why not use network tables?

Here is an example in python.

NetworkTable sd = NetworkTable.getTable("SmartDashboard");

sd.getNumber('dsTime');

sd.putNumber('robotTime', 10);

I would second Network Tables. It's what we are using to use vision processing on our Driver Station.
