#define GPIO_SPEC_AND_COMMA(button_or_led) GPIO_DT_SPEC_GET(button_or_led, gpios),

I find this code in the buttons and led .c file

Hello,

You are inside the dk_buttons_and_leds library. You should not do any change here. 

If you would like to know in general how macro works can follow this link C Preprocessor and Macros (programiz.com), Preprocessors in C - TechVidvan

Thanks.
