	Create an BusInOut, connected to the specified pins.
void	write (int value)
	Write the value to the output bus.
int	read ()
	Read the value currently output on the bus.
void	output ()
	Set as an output.
void	input ()
	Set as an input.
void	mode (PinMode pull)
	Set the input pin mode.
int	mask ()
	Binary mask of bus pins connected to actual pins (not NC pins) If bus pin is in NC state make corresponding bit will be cleared (set to 0), else bit will be set to 1.
BusInOut &	operator= (int v)
	A shorthand for write()
DigitalInOut &	operator[] (int index)
	Access to particular bit in random-iterator fashion.
	operator int ()
	A shorthand for read()
Protected Attributes
int	_nc_mask
	Mask of bus's NC pins If bit[n] is set to 1 - pin is connected if bit[n] is cleared - pin is not connected (NC)

Detailed Description

A digital input output bus, used for setting the state of a collection of pins.

Synchronization level: Thread safe

Definition at line 30 of file BusInOut.h.

Constructor & Destructor Documentation

Create an BusInOut, connected to the specified pins.

Parameters:

p<n>	DigitalInOut pin to connect to bus bit p<n> (p5-p30, NC)

Note:: It is only required to specify as many pin variables as is required for the bus; the rest will default to NC (not connected)
