Create an BusInOut, 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. | |
void | output () |
Set as an output. | |
void | input () |
Set as an input. | |
void | mode (PinMode pull) |
Set the input pin mode. | |
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. | |
BusInOut & | operator= (int v) |
A shorthand for write() | |
DigitalInOut & | operator[] (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) |

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)
