RE: GPIO Cannot be Programmed

Hi,

Was it intentional that you only used nrf_gpio_pin_clear and not nrf_gpio_pin_set in the above code?

Can you test with a basic application without anything else, to make sure nothing else is controlling the pins? For instance something like this:

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

#define GPIO_OUTPUT_BUZZER 17
#define GPIO_OUTPUT_VIBRATION 18

void main(void)
{
    nrf_gpio_cfg_output(GPIO_OUTPUT_BUZZER);
    nrf_gpio_cfg_output(GPIO_OUTPUT_VIBRATION);
    
    while(1)
    {
        nrf_gpio_pin_clear(GPIO_OUTPUT_BUZZER);
        nrf_gpio_pin_set(GPIO_OUTPUT_VIBRATION);
        
        nrf_delay_ms(500);

        nrf_gpio_pin_clear(GPIO_OUTPUT_BUZZER);
        nrf_gpio_pin_set(GPIO_OUTPUT_VIBRATION);
}

Best regards,
Jørgen
