Ok, I think we need some clarification. The 150 deg/sec gyro that FIRST is providing shouldn't require any jumpering. You need TWO pwms, one for the yaw rate signal, the other for temperature correction signal. The temperature correction is handy because the yaw rate gyro outputs a voltage (0-5volts) proportional to the rate of twist. At 0 deg/sec the output is nominally 2.5 volts. Temperature makes the 0 point drift up or down. So in competition it is possible that the gyro temperature may change and thus throw off the reading.

Now what I was talking about for jumpering is the Eval board you can order directly from Analog Devices, which is what the supplied link is describing. The drawing shows pin 1 and pin 20. The rest of the pins are numbered counter clockwise (looking from the top of the board, not the pin side). The EB has pin 1 printed on the board.

Uh does this help or make it even more confusing?
