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. | |
BusOut & | operator= (int v) |
A shorthand for write() | |
DigitalOut & | 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 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)
