       if(!gpio_dev)

        return 0;
       }
	ret = gpio_pin_configure(gpio_dev,button, GPIO_INPUT);

	printk("Press the button\n");
	
		while (1)
		{
			int val = gpio_pin_get(gpio_dev,button);
			
			if (val!= 0)
			{
			count=0;
			}
			
			count++;
			printk("count =%d\n",count);
			k_msleep(SLEEP_TIME_MS);
		}

}

when I press button count  value not changing, if anyone know where I did wrong please help me to solve this.

thank you
