A simple & compact PinChangeInterrupt library for Arduino.
PinChangeInterrupt library with a resource friendly implementation (API and LowLevel). PinChangeInterrupts are different than normal Interrupts. See readme for more information.
This library is compatible with the avr architecture so you should be able to use it on the following Arduino boards:
Note: while the library is supposed to compile correctly on these architectures, it might require specific hardware features that may be available only on some boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
