Interrupts and Crumbuino-128
Jul 8th, 2015 at 11:46am
Hello, all.

I use an Crumbuino 128 from chip45.com and I have a strange problem with the interrupts
when I connect two quadrant encoders on port 4 - 7 and 5 - 6 then I must use the INT4 and INT5
to handle the interrupts right!

But this are not working it's only worked with INT0 and INT1


const int aEncMtrL = 4;        //INT4 interrupt pin
const int bEncMtrL = 7;        //determines the direction of travel
const int aEncMtrR = 5;        //INT5 interrupt pin
const int bEncMtrR = 6;        //determines the direction of travel

attachInterrupt(INT4, encoderISR_L, RISING);   this must by working but it doesn't
attachInterrupt(INT5, encoderISR_R, RISING);

attachInterrupt(INT0, encoderISR_L, RISING);   this working but it's not the right way   
attachInterrupt(INT1, encoderISR_R, RISING);

can someone help my with this were I can find an solution for this.
