pi4j-v2 DigitalInput falling edge

[piotrkolo]

Hello,

I try to use digital input to react on falling edge of the signal.

Currently I have following code, this recognises state good but seems it is configured as described here:
"// (configure pin edge to both rising and falling to get notified for HIGH and LOW state" so this is:

    public HallSensorComponent(Context pi4j, int addressHall) {
        this.digitalInputHall = pi4j.create(buildDigitalInputConfig(pi4j, addressHall));
        this.addListener(this::dispatchSimpleEvents);
    }
    
    protected DigitalInputConfig buildDigitalInputConfig(Context pi4j, int address) {
        return DigitalInput.newConfigBuilder(pi4j)
                .id("BCM-" + address)
                .name("Hall Input Sensor")
                .address(address)
                .pull(PullResistance.PULL_UP)
                .build();
    }
    
    public DigitalEventListener<HallSensorComponent.HallSignalState> addListener(EventHandler<HallSensorComponent.HallSignalState> handler) {
        return DigitalEventProvider.super.addListener(handler);
    }

How can I change this pi4j-v2 sample code so falling edge is a trigger?

Greetings, Piotr

I was looking in wrong direction. Extension by debouncing setting solved my issue.
