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
