Detailed Description

Use this singleton if you need to chain interrupt handlers.

Synchronization level: Thread safe

Example (for LPC1768): 

 #include "InterruptManager.h"
 #include "mbed.h"

 Ticker flipper;
 DigitalOut led1(LED1);
 DigitalOut led2(LED2);

 void flip(void) {
     led1 = !led1;
 }

 void handler(void) {
     led2 = !led1;
 }

 int main() {
     led1 = led2 = 0;
     flipper.attach(&flip, 1.0);
     InterruptManager::get()->add_handler(handler, TIMER3_IRQn);
 }
