C++ (Cpp) GPIOBUS_PIN_GET Beispiele

Beispiel #1

Datei: gpioiic.c Projekt: Alkzndr/freebsd

static int
gpioiic_getsda(device_t dev)
{
	struct gpioiic_softc		*sc = device_get_softc(dev);
	unsigned int			val;

	GPIOBUS_PIN_SETFLAGS(sc->sc_busdev, sc->sc_dev, sc->sda_pin,
	    GPIO_PIN_INPUT);
	GPIOBUS_PIN_GET(sc->sc_busdev, sc->sc_dev, sc->sda_pin, &val);

	return ((int)val);
}

Beispiel #2

static int
gpioiic_getscl(device_t dev)
{
	struct gpioiic_softc		*sc = device_get_softc(dev);
	unsigned int			val;

	GPIOBUS_LOCK_BUS(sc->sc_busdev);
	GPIOBUS_PIN_SETFLAGS(sc->sc_busdev, sc->sc_dev, SCL_PIN,
	    GPIO_PIN_INPUT);
	GPIOBUS_PIN_GET(sc->sc_busdev, sc->sc_dev, SCL_PIN, &val);
	GPIOBUS_UNLOCK_BUS(sc->sc_busdev);

	return ((int)val);
}
