Enabling PIN change interrupts

Hello,

You mention on your “examples/tutorials” page that “On the other hand the pin change interrupts can be enabled on many more pins.” (c.f. https://www.controllino.biz/tutorials/#1539865917813-1a5b68ae-0b15)

Is there any tutorial on how to do that ? I have a Controllino MAXI. I am not able to use pins other than D0, D1, INT0, INT1, SDA and SCL as interrupt pins.

Any help will be welcome.

Thank you.

Hello,

If you look for the ATmega2560 pinout you can see there are a lot of PCINTxx pins. All of them are able to be used as Pin Change Interrupt (PCINT).

You only have to look for “Pin Change Interrupt Arduino MEGA”. there are a lot of examples how to do that depending on your needs.

There are also ready to use libraries to do that.

regards

Marco
