FIRST Team 1296 is using the 2012 I2C accelerometer and we are getting data. It is very noisy and it drifts (almost too much to be usable) but the I2C link seems to work. We are in the middle of creating a derived class that filters the thing and resets it when the robot is sitting still (as determined by the encoders).

Is your sidecar powered properly? Did you connect it to the pins closest to the NXT connector (check the manual)? Are you sure your cable is good (check for end to end continuity and for an shorts from one pin to another)? Are you sure your cable is in the correct orientation (it is easy to plug in backwards on either side)?
