Multiple PWM signal reading on Arduino Mega 2560

Dear DuaneB,

I "Finally" succeeded in running both codes (Yours and the other one), thank you !!!

The problems come from the 'attachInterrupt' numbers assignment...
The following worked with my board, I don't really know why, but anyway, this is the only funtion I needed from this board, so, I'm happy (^_^)

  // PIN 2
  attachInterrupt(0,handleInterrupt_P2,CHANGE); // Catch up and down    
  
  // PIN 3
  attachInterrupt(1,handleInterrupt_P3,CHANGE); // Catch up and down   
  
  // PIN 18
  attachInterrupt(5,handleInterrupt_P18,CHANGE); // Catch up and down   
  
  // PIN 19
  attachInterrupt(4,handleInterrupt_P19,CHANGE); // Catch up and down

Thanks for all !!

Best Regards,

Stéphane
