Detailed Description

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

Definition at line 25 of file BusOut.h.

Constructor & Destructor Documentation

Create an BusOut, connected to the specified pins.

Parameters:

p<n>	DigitalOut pin to connect to bus bit <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)

operator int ( )

A shorthand for read()

BusOut& operator= ( int v )

A shorthand for write()

int read ( )

Read the value currently output on the bus.

Returns:: An integer with each bit corresponding to associated DigitalOut pin setting

void write ( int value )

Write the value to the output bus.

Parameters:

value An integer specifying a bit to write for every corresponding DigitalOut pin
