Detailed Description

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

Definition at line 25 of file BusInOut.h.

Constructor & Destructor Documentation

BusInOut ( 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 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)
