How to configure Port 1 pin in nrf52833 DK board?

[shadab]

I want to configure port1 pin 8 as output pin but it wont work

#include <stdbool.h>
#include <stdint.h>
#include "nrf_delay.h"
#include "nrf_gpio.h"


#define led0 NRF_GPIO_PIN_MAP(1,8)               // LED0 P1.8
 
/**
 * @brief Function for application main entry.
 */
int main(void)
{
    nrf_gpio_cfg_output(led0); // config the as output pin

    while(1)
    {

          nrf_gpio_pin_toggle(led0);
          nrf_delay_ms(1000);

    }
}

Hi,

I tested your code on a nRF52833 DK and verified with a logic analyzer that P1.08 pin is toggling correctly.

Do you have anything connected to the pin, or some other code in your application that could configure the pin for use with some other peripheral?

Best regards,
Jørgen

Hi Jorgen

After your inputs I check and modified my code for different pins also,but on port 1 i didnt find any output.I share the code and logic analyser result for port 0 and port 1.For port 0 I get the output but not for port 1

#include <stdbool.h>
#include <stdint.h>
#include "nrf_delay.h"
#include "nrf_gpio.h"


#define led0 NRF_GPIO_PIN_MAP(0,13)
#define led1 NRF_GPIO_PIN_MAP(1,8)                 // LED0 P1.8
 
/**
 * @brief Function for application main entry.
 */
int main(void)
{
    nrf_gpio_cfg_output(led0); // config the as output pin
    nrf_gpio_cfg_output(led1); // config the as output pin


    while(1)
    {

          nrf_gpio_pin_toggle(led0);
          nrf_delay_ms(500);
          nrf_gpio_pin_toggle(led1);
          nrf_delay_ms(500);

    }
}

Have you tested other pins on port 1? 

Like I said, I'm not able to reproduce this on my DK, and verified that P1.08 is toggling on my logic analyzer.

Can you share the full project? Which SDK version are you using?

[shadab]

yes I tested with every pin of port 1

I used sdk 17

Can you test this precompiled hex-file on your DK? It should toggle P1.08 every 1 second (compiled from your first sample code): blinky_p108_pca10100.hex

If this works, there is most likely something wrong in your project settings or build-system. If it does not work, I think that your DK is somehow damaged/broken.
