#include <PortIn.h>

Public Member Functions

 PortIn (PortName port, int mask=0xFFFFFFFF)
 Create an PortIn, connected to the specified port.
int read ()
 Read the value currently output on the port.
void mode (PinMode mode)
 Set the input pin mode.
 operator int ()

Detailed Description

A multiple pin digital input.

Example: 

 // Switch on an LED if any of mbed pins 21-26 is high

 #include "mbed.h"

 PortIn     p(Port2, 0x0000003F);   // p21-p26
 DigitalOut ind(LED4);

 int main() {
     while(1) {
         int pins = p.read();
         if(pins) {
             ind = 1;
         } else {
             ind = 0;
         }
     }
 }
