}

GPIO controller instance

func (*GPIO) Init ¶

func (hw *GPIO) Init(num int) (gpio *Pin, err error)

Init initializes a GPIO.

type Pin ¶

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

Pin instance

func (*Pin) High ¶

func (gpio *Pin) High()

High configures a GPIO signal as high.

func (*Pin) In ¶

func (gpio *Pin) In()

In configures a GPIO as input.

func (*Pin) Low ¶

func (gpio *Pin) Low()

Low configures a GPIO signal as low.

func (*Pin) Out ¶

func (gpio *Pin) Out()

Out configures a GPIO as output.

func (*Pin) Value ¶

func (gpio *Pin) Value() (high bool)

Value returns the GPIO signal level.
