Class DigitalInputDevice.Builder

java.lang.Object

com.diozero.api.DigitalInputDevice.Builder

Enclosing class:

DigitalInputDevice

public static class DigitalInputDevice.Builder
extends Object

Digital input device builder. Default values:

• pud: GpioPullUpDown.NONE
• trigger: GpioEventTrigger.BOTH
• activeHigh: set to false if pud == GpioPullUpDown.PULL_UP, otherwise true (assumes normally open wiring configuration)
• deviceFactory: DeviceFactoryHelper.getNativeDeviceFactory()

Either a GPIO number or a PinInfo instance must be specified. Using a PinInfo instance allows input devices to be identified by either physical pin number or GPIO chip and line offset. The optional activeHigh parameter default value assumes a normally open wiring configuration, however, this can be overridden for normally closed configurations as well as scenarios where pud is GpioPullUpDown.NONE and an external pull up/down resistor is used.
