DetectSignal

[EliasA]

Hi,

I am new in this area. I wanted to use the detect "signal" but it doesn't work as protected. This is my main :

     uint32_t pin = 25;
     uint32_t led3 = 15;
     //nrf_gpio_cfg(led3, NRF_GPIO_PIN_DIR_OUTPUT, NRF_GPIO_PIN_INPUT_CONNECT, NRF_GPIO_PIN_PULLUP, NRF_GPIO_PIN_S0S1, NRF_GPIO_PIN_SENSE_LOW);
     nrf_gpio_cfg_output(led3);
     nrf_gpio_pin_clear(led3);

     nrf_gpio_cfg(pin, NRF_GPIO_PIN_DIR_INPUT, NRF_GPIO_PIN_INPUT_CONNECT, NRF_GPIO_PIN_PULLUP, NRF_GPIO_PIN_S0S1, NRF_GPIO_PIN_SENSE_LOW);

    for (;;)
    {
       if(NRF_GPIOTE->EVENTS_PORT != 0){
          nrf_gpio_pin_toggle(led3);
          NRF_GPIOTE->EVENTS_PORT = 0;
       }

        (void)sd_app_evt_wait();

    }

I just try to detect when the detect signal is HIGH. Normally the pin 25 goes HIGH when I press the Button 4. But the result is that the NRF_GPIOTE->EVENTS_PORT is always LOW.

Thanks for your help.

Which area - programming in general? microcontrollers in general? BLE in general? Nordic BLE microcontrollers in particular?

In microcontrollers in general.

For the benefit of others who may come along with similar questions, please describe what was the problem, and how you solved it.

I use the different latch and read the value their and then clear it.
