Detailed Description

This library provides a simple PWM decoder class.

The approach is based on installing two interrupt routines for the rising and falling edges of an input pin and measuring the time between the two events.

Example: 

 #include "mbed.h"
 void main()
 {
     pulse_decoder pulse(D7);

     while(true) {
         printf("Pulse high = %5d low = %5d (us) Period = %5d\n", 
           pulse.get_high_period(), pulse.get_low_period(), 
           pulse.get_high_period() + pulse.get_low_period());  
         wait(.2);
     }    
 }
