Arduino Library Pin Definitions

Hello,

I am trying to find where in Arduino WiFi NINA library the pins that the ATSAMD21 are connected to are defined. Also, in general where are the pins defined?

Do you know?

Thank you

The pins are usually defined in the pins_arduino.h file located somewhere below were you installed the IDE. For example for an arduino mega on my Windows machine, it is here:
C:\Program Files (x86)\Arduino\hardware\arduino\avr\variants\mega

I don't have your board installed, but it is probably near by if you poke around

Thank you for your response.

I don't think I explained it well.

Basically, when I plug in my Arduino MKR 1010 and upload a sketch to blink and LED through WiFi communication, I use the Arduino WiFi NINA library.

What I am wondering is where are the pin connections defined in the sketch. When I upload that example sketch, it never defines what connections the ATSAMD21 on the MKR 1010 is talking to the Ublox NINA W-10 through. How does the sketch know what communications lines ATSAMD21 and module are connected on?

Is this defined in the Arduino WiFi NINA library or somewhere else?

And where could I find it?

Thank you!
