Dear Sirs,

I am using example anr_hrm nrf_sdk_15.3.0 I would like to use PINs on/off

software s212

#include "nrf.h"

#include "nrf_gpio.h"

#include "nrf_delay.h"

 

#define LED1_PIN 22

int main (void)

{

   nrf_gpio_cfg_output(LED1_PIN);

   nrf_gpio_pin_clear(LED1_PIN);

   while(1)

   {

       nrf_gpio_pin_toggle(LED1_PIN);

       nrf_delay_ms(1000);

   }

}

Please find under the code. unfortynately 22 pin is not seting down or up.

22 pin and 23, 24,25 are always up

Could you please give me some solution for it

With Best Regards

What DK are you using?

Does the blinky work?

I do not have any good suggestion than to try and fail a bit. Try some different gpio's also.

Best regards,
Kenneth
