GPIO aliases to J8 pins

Variables

var ErrInvalid = errors.New("invalid pin name")

ErrInvalid indicates the pin name does not match a known pin.

Functions

func MustPin

func MustPin(s string) int

MustPin converts the string to the corresponding pin number or panics if that is not possible.

func Pin

func Pin(s string) (int, error)

Pin maps a pin string name to a pin number.

Pin names are case insensitive and may be of the form J8pX, GPIOX, or X.
