Detailed Description

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

Constructor & Destructor Documentation

mbed::BusIn::BusIn ( PinName  p0,
PinName  p1 = NC,
PinName  p2 = NC,
PinName  p3 = NC,
PinName  p4 = NC,
PinName  p5 = NC,
PinName  p6 = NC,
PinName  p7 = NC,
PinName  p8 = NC,
PinName  p9 = NC,
PinName  p10 = NC,
PinName  p11 = NC,
PinName  p12 = NC,
PinName  p13 = NC,
PinName  p14 = NC,
PinName  p15 = NC 
)

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)

Member Function Documentation

void mbed::BusIn::mode ( PinMode  pull)

Set the input pin mode

Parameters
modePullUp, PullDown, PullNone
mbed::BusIn::operator int ( )

A shorthand for read()

int mbed::BusIn::read ( )

Read the value of the input bus

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