Public Member Functions

 BusOut (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 BusOut, 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.
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.
BusOutoperator= (int v)
 A shorthand for write()
DigitalOutoperator[] (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)

Constructor & Destructor Documentation

BusOut ( 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 BusOut, connected to the specified pins.

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

Synchronization level: Thread safe

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)
