I'm trying to run the test code <http://www.parallax.com/Portals/0/Downloads/docs/prod/sens/27922-LISY300-BS2ExampleCode.zip> for our lisy300 gyroscope, but all the debug screen reads are zeros. If anyone could help us troubleshoot it would be appreciated.

    Have you double checked all of your connections between the Gyro and the BSII? What about Power and ground to the Gyro?

    The example code has this for a pin connection for the signals, but does not show power and ground connections to the Gyro
    Dout PIN 0 ' P0 <-- Dout (LISY300.2)

    SCLK PIN 1 ' P1 --> SCLK (LISY300.4)

    CSn PIN 2 ' P2 --> /CS (LISY300.5)


    Power(Pin1) and Ground(Pin3) for the LISY300 should also be shared with Power(Vdd) and Ground(Vss) on the BSII.
