Pro Micro pin reassignment? about dcservo HOT 7 CLOSED

from dcservo.

Hmm, according to the sparkfun page, ProMicro has 5 external interrupts. Shouldn't it be possible to just swap them? Is this accurate?:

"The Pro Micro has five external interrupts, which allow you to instantly trigger a function when a pin goes either high or low (or both). If you attach an interrupt to an interrupt-enabled pin, you’ll need to know the specific interrupt that pin triggers: pin 3 maps to interrupt 0, pin 2 is interrupt 1, pin 0 is interrupt 2, pin 1 is interrupt 3, and pin 7 is interrupt 4."

That is correct but they do not use the term INT4 or INT5

And yes, they can be changed, just remember to update any PIN* code accordingly. The image below shows the port and number for each pin:

Please note INT6 (on pin 7) is not edge sensitive and it can only work by level.

Thanks! I guess this means that INT6 would have to be used for the STEP interrupt, since it will trigger on CHANGE but not RISING\FALLING. Would you expect there to be any downside to doing that?

CHANGE=RISING+FALLING

You can select HIGH instead and use it for the STEP input.
