Function Documentation

int NutRegisterOwiBus_BB	(	NUTOWIBUS *	bus,
		int	txrx_port,
		uint_fast8_t	txrx_pin,
		int	pullup_port,
		uint_fast8_t	pullup_pin
	)

Register the One-Wire bus.

Parameters:

bus	The returned NUTOWIBUS.
txrx_port	The port to use for the One_Wire bus.
txrx_pin	The pin to use for the One_Wire bus.
pullup_port	If given, port to control strong pull-up for parasitic powered devices.
pullup_pin	The pin to control strong pull-up for parasitic powered devices.

Returns:

OWI_SUCCESS on success, a negative value otherwise.
