Types

type Pin

type Pin struct {
	N   string // Should be immutable
	Num int    // Should be immutable
	Fn  string // Should be immutable

	sync.Mutex            // Grab the Mutex before modifying the members to keep it concurrent safe
	L          gpio.Level // Used for both input and output
	P          gpio.Pull
	EdgesChan  chan gpio.Level // Use it to fake edges
}

Pin implements gpio.Pin.

Modify its members to simulate hardware events.

func (*Pin) Function

func (p *Pin) Function() string

Function return the value of the Fn field of the pin.

func (*Pin) Halt

func (p *Pin) Halt() error

Halt implements conn.Resource.

It has no effect.

func (*Pin) In

func (p *Pin) In(pull gpio.Pull, edge gpio.Edge) error

In is concurrent safe.

func (*Pin) Name

func (p *Pin) Name() string

Name returns the name of the pin.

func (*Pin) Number

func (p *Pin) Number() int

Number returns the pin number.

func (*Pin) Out

func (p *Pin) Out(l gpio.Level) error

Out is concurrent safe.

func (*Pin) Pull

func (p *Pin) Pull() gpio.Pull

Pull implements gpio.PinIn.

func (*Pin) Read

func (p *Pin) Read() gpio.Level

Read is concurrent safe.

func (*Pin) String

func (p *Pin) String() string

func (*Pin) WaitForEdge

func (p *Pin) WaitForEdge(timeout time.Duration) bool

WaitForEdge implements gpio.PinIn.
