Detailed Description

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

Definition at line 26 of file BusIn.h.

Constructor & Destructor Documentation

Create an BusIn, connected to the specified pins.

Parameters:

<n>	DigitalIn 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)

Definition at line 20 of file BusIn.cpp.

void mode ( PinMode pull )

Set the input pin mode.

Parameters:

mode	PullUp, PullDown, PullNone

Definition at line 52 of file BusIn.cpp.

operator int ( )

A shorthand for read()

Definition at line 61 of file BusIn.cpp.

int read ( )

Read the value of the input bus.

Returns:: An integer with each bit corresponding to the value read from the associated DigitalIn pin
