From the
attachInterrupt
docs, the recommended usage is:This currently does not work with the SAMD core because
digitalPinToInterrupt
is used insideattachInterrupt
, so the pin number must be passed in.This patch addresses this by changing
digitalPinToInterrupt
to return the argument passed in.attachInterrupt
anddetachInterrupt
will useg_APinDescription[pin].ulExtInt;
to map the pin to interrupt number directly.It also moves
digitalPinToInterrupt
insideArduino.h
(ifARDUINO_SAMD_VARIANT_COMPLIANCE
is >= 1.6.5). Existing behaviour will be used in variants with older compliance levels.I've also added a new change log for variant compliance changes.
