ItsyBitsy 32u4 - 3V Interrupt Question

Projects Programming
1

I need to do an interrupt when GPIO 15 goes high.

#include "PinChangeInterrupt.h"

attachInterrupt(digitalPinToInterrupt(15), Abort_Dect, RISING);

The code does not work, so what am I going wrong?

  1. You didn't post a complete code.
  2. You didn't say what the code was supposed to do.
  3. You didn't say what the code actually did.

according to the docs: https://docs.arduino.cc/language-reference/en/functions/external-interrupts/attachInterrupt/

you can use pins 0,1,2,3,7 (Leonardo line in the docs since it uses the 32u4)

You are including PinChangeInterrupt.h but not using it.

attachPinChangeInterrupt(digitalPinToPinChangeInterrupt(15), Abort_Dect, RISING);

Thanks oqibidipo I will try your suggested code shortly.

Thank you for sharing your wisdom.

One more question if I may. Is there a way to check if the interrupt is enabled using the PinChangeInterrupt library?
