Detailed Description
A multiple pin digital input.
Synchronization level: Interrupt safe
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; } } }
