we are having trouble with the yaw rate gyroscopes. we had 6 or 7 of these we were trying to get to use as sensors for turning. we were using the sample program (basic)that is in robotC 4x. We had one gyro that read just fine and one group of students was programming that machine. all the other gyros would do one of two things. Either it would not show data return info on the sensor feedback or the data number were going anywhere from about 50 to 4000 even though the sensor itself was still.
