Calling Disable_Gyro() will disable the gyro software and allow
you to use the ADC for other purposes.

One way around this is to double the timer 2 interrupt rate and then interleave your ADC measurements within the timer 2 ISR. If there's interest, I can modify the code to include accelerometer measurements too.

Can we not simply use a standard analog input for the gyro? Why is it necessary to use the ADC as set up in the example code?

Thanks - Jeff
