I have a project that uses a nodemcu and it includes an rf receiver, I created the pcb board already etc etc... so I've already chosen D7 (GPI013) before reading on connecting the rf receiver and found that a lot of people are saying to connect it to the interrupt pin and for the case of an Arduino it was pin 2 and for the nodemcu it's D3 (GPIO0).
UPDATE: the pin in question is the data pin for the rf receiver, this would be connected to D7 (GPIO13) because of the trace on the board. it is purely used for receiving the data it picks up and giving it to the nodemcu to handle.
Can I just use a different pin which in my example is D7 (GPIO13) or does it HAVE to be an interrupt pin?
Side note: I'm aware of the advantage of using an interrupt pin where that it takes priority over code running.
