    Discussion

    Do not call this directly. This is called automatically by the system when the instance's refcount goes to 0. To decrement the refcount, call release() on the object.

  • Construct a new instance of the IIR TimeFilter class

    Declaration

    virtual bool initFilter( uint32_t expectedInterval, uint32_t multiIntervalCount = 1);

    Parameters

    ExpectedInterval

    Expected interval of time captures

    MultiIntervalCount

    Optionally calculate the count between ExpectedInterval
