Summary

Which Arduino Nano Matter GPIOs are interrupt-capable?

The https://docs.arduino.cc/resources/pinouts/ABX00112-full-pinout.pdf does not provide this information.

Thank you!

Trying again raised this error.

FREERTOS ASSERT ( !( ( xTaskGetSchedulerState() == taskSCHEDULER_SUSPENDED ) && ( xTicksToWait != 0 ) ) )

Both the SP and I²C bus are used. I tried with multiple GPIOs, both analog like A0 and digital like D1, to no avail.

Hello @rei-vilo,
All GPIO pins are interrupt capable - you can register callbacks to them.
The assertion you posted is resulting from calling an OS function (likely delay) from the callback function. Be careful - the callbacks are invoked from an interrupt context. If you post your sketch I can help you hunt down the issue which causes the assertion.

Thank you for the update. Unfortunately, I no longer have the project at hand to perform a new test.
