RE: Configuration of Digital Input/Output pins on nRF52

I was looking something like this.

I have done my own code. Sorry if the question was too simple, sometimes libraries fail starting from the most basic example.

#include <stdbool.h>
#include "nrf.h"
#include "nrf_drv_gpiote.h"
#include "app_error.h"
#include "boards.h"


#define GPIO_PIN_17     17
#define GPIO_PIN_18     18
#define GPIO_PIN_19     19
#define GPIO_PIN_20     20

#define GPIO_PIN_27     27
#define GPIO_PIN_28     28
#define GPIO_PIN_29     29
#define GPIO_PIN_30     30

#define S_ON     1
#define S_OFF    0



void gpio_init(void)
{

			// Pins as outputs
	    nrf_gpio_range_cfg_input(27,30,NRF_GPIO_PIN_PULLUP);
	
			// Pins as inputs
			nrf_gpio_range_cfg_output(17, 20);
			
}

/**
 * @brief Function for application main entry.
 */
int main(void)
{
    gpio_init();

    while (true)
    {
			
			if(nrf_gpio_pin_read(GPIO_PIN_27))
			{
				nrf_gpio_pin_write(GPIO_PIN_17, S_OFF);
			}
			else
			{
				nrf_gpio_pin_write(GPIO_PIN_17, S_ON);
			}
			
			if(nrf_gpio_pin_read(GPIO_PIN_28))
			{
				nrf_gpio_pin_write(GPIO_PIN_18, S_OFF);
			}
			else
			{
				nrf_gpio_pin_write(GPIO_PIN_18, S_ON);
			}
			
			if(nrf_gpio_pin_read(GPIO_PIN_29))
			{
				nrf_gpio_pin_write(GPIO_PIN_19, S_OFF);
			}
			else
			{
				nrf_gpio_pin_write(GPIO_PIN_19, S_ON);
			}
			
			if(nrf_gpio_pin_read(GPIO_PIN_30))
			{
				nrf_gpio_pin_write(GPIO_PIN_20, S_OFF);
			}
			else
			{
				nrf_gpio_pin_write(GPIO_PIN_20, S_ON);
			}
	
 
    }
}
