DigitalInputEvent

public DigitalInputEvent(int gpio,
long epochTime,
long nanoTime,
boolean value)

Constructs an input event from a digital device. See (@link com.diozero.api.DeviceEvent} for first 3 parameters.

Parameters:

gpio - GPIO number

epochTime - Unix epoch time: milliseconds elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds

nanoTime - The Java Virtual Machine's high-resolution time source, in nanoseconds (note this is unrelated to epochTime and uses CLOCK_MONOTONIC in the C clock_gettime() function)

value - the event value

Method Details

getValue

public boolean getValue()

Returns the underlying GPIO state. Note does not compensate for active high / low.

Returns:

the physical digital pin state

isActive

public boolean isActive()

Determine if the event is active or not compensating for active high / low wiring

Returns:

if the event should be consider active or inactive

toString

public String toString()

Overrides:

toString in class Object
