type Pin ¶

type Pin struct {
	// These should be immutable.
	N   string
	Num int
	Fn  string // TODO(maruel): pin.Func in v4.

	// Grab the Mutex before accessing the following members.
	sync.Mutex
	L         gpio.Level // Used for both input and output
	P         gpio.Pull
	EdgesChan chan gpio.Level  // Use it to fake edges
	D         gpio.Duty        // PWM duty
