Check your board!

P0.00 & P0.01 are connected to crystal oscillator in My board(nRF52833-DK) so its not working.some for others pins also.

please check your DK.

Hi,

The DK use as default the P0.0 for the LFCLK crystal. You can try to disconnect the LFCLK by cutting solder brigde SB2 and SB1 and then switch the LFCLK source.

Hi Jared,

I just want to be able to pull the P0.0 pin high or low which I'm not able to do using any of the example codes. There is absolutely no voltage change on this line. I tried adding the io functions to ble & peripheral example codes. Can you please check at your end?

Note - I'm able to see voltage changes on few other pins except P0.00. I'm using a nrf52832 DK.

Thank you for your reply. I tried adding your logic to the example code but it didnt work. I also commented all the statements initializing or using this led.

Hi,

If you're using the DK then the buttons for the LEDS are P0.17-P0.20.

Ok, the way I did it was:

//For init
err_code = nrf_drv_gpiote_init();
APP_ERROR_CHECK(err_code);

nrf_drv_gpiote_out_config_t out_config = GPIOTE_CONFIG_OUT_SIMPLE(false);
    
err_code = nrf_drv_gpiote_out_init(PIN_LED, &out_config);
APP_ERROR_CHECK(err_code);

//For changing states
nrf_drv_gpiote_out_set(PIN_LED);

nrf_drv_gpiote_out_clear(PIN_LED);

Do let us know if it solves it.

Edit_1: You would also need to add this library (this library provides a lot of functions regarding IOs including interrupts and all so I would recommend using this.

#include "nrf_drv_gpiote.h"
