Remarks
The default polarity value is Falling. See GpioChangePolarity for more information on polarity values. Counting a single edge can be considerably more efficient than counting both edges.
The following exceptions can be thrown when setting the polarity:
- E_INVALIDARG - value is not a valid GpioChangePolarity value.
- HRESULT_FROM_WIN32(ERROR_BAD_COMMAND) - change counting is currently active. Polarity can only be set before calling Start() or after calling Stop().
