Help getting GPIO work for Zephyr and nRF52840

[ujur007]

I am struggling on how to use GPIO pins other than what are defined since last two days. At last, I am posting this discussions.
So, I want custom pin GPIO to attach LED or Buzzer.
What I tried so far is to change the .dts file and add some custom definition like the following.

buzzer,user {
        buzzer1: buzzer_1 {
            gpioee = <&gpio1 9 GPIO_ACTIVE_HIGH>;
            label = "Buzzer custom";
        };
    };

The in my app code I tried to get the device struct using following code. But I could not get the required device. I tried some different syntax and settings but honestly I do not get a clue how it works.

#define BUZZER DT_PATH(buzzer_user)
const struct gpio_dt_spec buzzer = GPIO_DT_SPEC_GET(BUZZER, gpioee);

If you do not know about the device tree macros I recommend that you check this video

Sorry but this was solved and there was some mistake in my code in the device tree sections. Thanks for posting. you can mark it solved.
