DigitalInputDevice.Builder (diozero - Core 1.3.0 API)

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.
