How to configure the min and max switch #116

Hello, I can't figure out how to configure the min and max limit switches. And what are the pins. I am not fluent in C so...
This is on a rpi pico if someone could help me. It seams that is done via the driver.c file but I don't know how.
Thanks a lot.

It is done in the map file by assigning pins to the function.
E.g. #define X_LIMIT_PIN_MAX 12

Easiest is to copy an existing map file to my_machine_map.h, modify it and enable that in my_machine.h.
