How to use the GPIO for switching purpose?

[kashyap velpuru]

#include "nrf.h"
#include "nrf_gpio.h"
#include "nrf_delay.h"

#define LED1_PIN  P0.17 

int main (void)
{
   nrf_gpio_cfg_output(LED1_PIN);
   nrf_gpio_pin_set(LED1_PIN, 1);
}

I wanted pin 17 to be high so as to switch on a relay based circuit!

Please

1. don't post twice
2. use the code formatting button to format your code so it can actually be read (you can edit your post and fix it)

Hi kashyap! You should try changing your code to this instead:

#define LED1_PIN 17
-
int main (void)
{
    nrf_gpio_cfg_output(LED1_PIN);
    nrf_gpio_pin_set(LED1_PIN);
}
