Create an BusIn, connected to the specified pins. | |
BusIn (PinName pins[16]) | |
Create an BusIn, connected to the specified pins. | |
int | read () |
Read the value of the input bus. | |
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. | |
operator int () | |
A shorthand for read() | |
DigitalIn & | operator[] (int index) |
Access to particular bit in random-iterator fashion. |

Create an BusIn, connected to the specified pins.
- Parameters:
-
p0 DigitalIn pin to connect to bus bit p1 DigitalIn pin to connect to bus bit p2 DigitalIn pin to connect to bus bit p3 DigitalIn pin to connect to bus bit p4 DigitalIn pin to connect to bus bit p5 DigitalIn pin to connect to bus bit p6 DigitalIn pin to connect to bus bit p7 DigitalIn pin to connect to bus bit p8 DigitalIn pin to connect to bus bit p9 DigitalIn pin to connect to bus bit p10 DigitalIn pin to connect to bus bit p11 DigitalIn pin to connect to bus bit p12 DigitalIn pin to connect to bus bit p13 DigitalIn pin to connect to bus bit p14 DigitalIn pin to connect to bus bit p15 DigitalIn pin to connect to bus bit
- 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)
