Write the value to the output bus. | |
int | read () |
Read the value currently output on the bus. | |

Set as an output. | |
void | input () |
Set as an input. | |
void | mode (PinMode pull) |
Set the input pin mode. | |
int | mask () |

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)
Member Function Documentation
void input | ( | ) |
Set as an input.
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.
- Returns:
- Binary mask of connected pins
Definition at line 81 of file BusInOut.h.
void mode | ( | PinMode | pull ) |
Set the input pin mode.
- Parameters:
-
mode PullUp, PullDown, PullNone
operator int | ( | ) |
A shorthand for read()
DigitalInOut& operator[] | ( | int | index ) |
Access to particular bit in random-iterator fashion.
void output | ( | ) |
Set as an output.
int read | ( | ) |
Read the value currently output on the bus.
- Returns:
- An integer with each bit corresponding to associated DigitalInOut 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 DigitalInOut pin
Field Documentation
int _nc_mask [protected] |
