Here is the relevant shield on sparkfun: http://www.sparkfun.com/products/9026

AFAIK we used the "stock" Arduino Wire library on this year's competition robot to communicate the shooter angular velocity with the cRIO.

We just had to use the transaction method of the I2C class.

relevant part of our code:

UINT8 valuesGotten[2] = {0, 0};
I2CArduino->Transaction(NULL, 0, valuesGotten, 2);
UINT16 fullNumber = (valuesGotten[1] << 8) | valuesGotten[0];

Full code for reading our sensor is attached. I don't currently have access to the arduino side, though.
