Gyro not sensing angular change

You could also use the cRio analog input as a multimeter, and graph the analog channel output on the front panel. It should be at the centerpoint when not moving then go up or down when moving. Try going as fast as you can, and see if you can see a difference. Also, if you click a wire when the code is running, you can probe the wire to see the value, helpful when debugging problems like this.

Yeah, we already used the multimeter to check connectivity but we can't probe it because its shielded. I also probed the angle wire in LabView coming out of "Gyro: Get Angle" and it was the steady drift. Anywhere between -0.1 and 0.1 (usually within the hundredth decimal place)
