public class DebouncedDigitalInputDevice
extends WaitableDigitalInputDevice

Represents a generic input device with typical on/off behaviour. This class extends 'WaitableInputDevice' with machinery to fire the active and inactive events for devices that operate in a typical digital manner: straight forward on / off states with (reasonably) clean transitions between the two.

Constructor Details

DebouncedDigitalInputDevice

public DebouncedDigitalInputDevice(int gpio) throws RuntimeIOException

Throws:

RuntimeIOException

DebouncedDigitalInputDevice

public DebouncedDigitalInputDevice(int gpio, GpioPullUpDown pud, float debounceTime) throws RuntimeIOException

Parameters:

gpio - GPIO

pud - Pull-up/down configuratoin

debounceTime - Specifies the length of time (in seconds) that the component will ignore changes in state after an initial change. This defaults to 0 which indicates that no bounce compensation will be performed.

Throws:

RuntimeIOException - if an I/O error occurs
