Does anyone have any suggestions for testing our kit gyro to see if it is alive? Is there a way to do it with a voltage meter?

does Get_Analog_Value( rc_ana_in01 ) return a value that should change when the gyro chip is rotated, or do you have to initialize the gyro before it will function at all?

An important point to understand about the gyro is it only returns a rate of rotation while it is moving. This rate is around 2.5 vdc when still. So, the software needs to integrate the variation in rate over time to give you an angle relative to it's original angle. So, the answers given in the programming section may contain your solution.
Sorry if this was already explained, but that is what happens when you "cross-post".
As for using a multi-meter to test it may be difficult. If I recall correctly, the KOP gyro's output changes by 12mv/deg/s of rotation and is limited to 80 deg/sec. You would need a very fast and sensitive meter to catch it. So, try connecting the meter between T and gnd. Rotate the gyro by hand and see if the output changes during rotation. The other alternative is to use a o'scope.
