Blinking led custom board

[Juniorprogrammer]

Hi,

I have made my own custom board with the nrf52811. Therefore I was using the nrf52dk. 

I have made connection with my custom board and simply want to blink an led. The pin I´m using is p0.13.

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

#define led 13

/**
 * @brief Function for application main entry.
 */
int main(void)
{
    /* Configure board. */
    nrf_gpio_cfg_output(led);

    /* Toggle LEDs. */
    while (true)
    {
      nrf_gpio_pin_set(led);
      nrf_delay_ms(500);
      nrf_gpio_pin_clear(led);
      nrf_delay_ms(500);
    }
}

This is how I want to blink the led. Should this work fine or do I have to configure the pin on another way? And is it electrically good?

Hi Ahmet, 

I did not understand correctly. You are using a custom board based on nRF52811 and are you using the nRF52dk just to confirm the connections and programming before that? If so, then I would recommend you to use the nRF52840DK.

The nRF52DK is used for developing for ICs nRF52832, nRF52810, or nRF52805.

Best Regards,

Hi,

No I want to test my board by using blinky, but I connected the led on my custom board on p0.13. How can I blink the led? Is it possible?

Hi Ahmet,

And you are using the nRF Connect SDK for the same?

Hi Priyanka,

No I’m using ses and program with the programmer on the nrf52dk using swdio and swdclk.

Okay, so I guess you are using the nRF5 SDK in the SES. Your code and connections are fine. But you could also take a look at our reference. This is how we have the connections in the DKs

I would suggest you to take a look at the following guides first, as a beginner:
