Hi,

You're mixing the usage between the GPIOTE and the GPIO driver which is not the same peripheral. Can you test this simple fw on your code and see if you're able to see LED1 blinking? If you are, can you change PIN 17 to 10 with CONFIG_NFCT_PINS_AS_GPIOS added to the preprocessor settings and see if you're also able to see PIN 10 toggling?

regards

Jared

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



#define PIN 17


int main(void)
{

nrf_gpio_cfg_output(PIN);


while(1)
{

    nrf_gpio_pin_toggle(PIN);
    nrf_delay_ms(500);
}

}

Hi Jared

I added CONFIG_NFCT_PINS_AS_GPIOS into preprocessor.

But still no drive gpio set high.

And also I can't read input gpio value of P0.03

Thanks.

Hi,

Pin P0.10 is used for NFC. You have to add CONFIG_NFCT_PINS_AS_GPIOS to your preprocessor settings.
