type InputPin interface {
	Read() (bool, error)
}

InputPin is the interface satisfied by GPIO input pins.

func Input(pinNumber int, activeLow bool) (InputPin, error)

Input initializes a GPIO input pin with the given pin number.

type InterruptPin interface {
	InputPin
	Wait(time.Duration) error
}

InterruptPin is the interface satisfied by GPIO interrupt pins.

func Interrupt(pinNumber int, activeLow bool, edge string) (InterruptPin, error)

Interrupt initializes a GPIO interrupt pin with the given pin number. The edge parameter must be "rising", "falling", or "both".

type OutputPin interface {
	Write(bool) error
}

OutputPin is the interface satisfied by GPIO output pins.

func Output(pinNumber int, activeLow bool, initialValue bool) (OutputPin, error)

Output initializes a GPIO output pin with the given pin number and initial logical value.

type Pin struct {
	// contains filtered or unexported fields
}

Pin represents a GPIO pin.

func (pin *Pin) Read() (bool, error)

func (pin *Pin) Wait(timeout time.Duration) error

Wait waits with the given timeout for a GPIO input pin to become active.

func (pin *Pin) Write(value bool) error

type TimeoutError struct {
	// contains filtered or unexported fields
}

TimeoutError indicates that a Wait operation on a GPIO input pin timed out.

func (t TimeoutError) Error() string
