the rio wouldn't have to send anything, only receive. so if i have a very fast loop in a separate thread, could i conceivably catch the data?

thats a great idea except the arduino uses analog pins 5 and 6 for I2C communication, and all 6 pins are used (3 for x y z) (3 for roll pitch yaw)

what about SPI? it was finished for labview but not for windriver
