read
Reads value from a digital input pin.
func read() -> Bool Returns
true or false of the logic value.
Reads value from a digital input pin.
func read() -> Bool true or false of the logic value.
import SwiftIOThe SwiftIO library allows you to access and control the hardware in an easy way.
final class DigitalInThe DigitalIn class is intended to detect the state of a digital input pin, either true or false.
@frozen struct BoolA value type whose instances are either true or false.
init(_ idName: Id, mode: Mode = .pullDown) Initializes a DigitalIn to a specified pin.
var interruptMode: InterruptMode { get set }The current interrupt mode: .rising, falling or bothEdge.
var mode: Mode { get set }The current input mode: .pullUp, .pullDown or .pullNone.
let obj: UnsafeMutableRawPointer@discardableResult func disableInterrupt() -> Result<(), Errno> Disables the interrupt until you enable it.
@discardableResult func enableInterrupt() -> Result<(), Errno> Enables the interrupt.
func getInterruptState() -> InterruptState Checks whether the interrupt is enabled.
func getMode() -> Mode Gets the configuration of the internal pull-up and pull-down resistor on a specified input pin.
@discardableResult func removeInterrupt() -> Result<(), Errno> Removes the interrupt.
@discardableResult func setInterrupt(_ mode: InterruptMode, enable: Bool = true, callback: @escaping () -> Void) -> Result<(), Errno> Adds a callback function to a specified input pin. It sets interrupt by detecting the changes of the signal.
@discardableResult func setMode(_ mode: Mode) -> Result<(), Errno> Sets the input mode, which means the pull-up and pull-down resistor pull-up and pull-down resistor.
enum InterruptModeDetermines the event to raise an interrupt: rising edge, falling edge or both.
enum InterruptStateDetermines whether the interrupt is enabled and will occur.
enum ModeThe digital input mode sets the pull resistors connected to a pin.
