How to correctly configure and read a pin status

[leron]

Dear All, I apologize in advance if it seems that the question has been already posed but it is still unclear to me. I have a pin (SIG_OK) and I want to read its logic value. I defined the inpus as:

nrf_gpio_cfg(SIG_OK, NRF_GPIO_PIN_DIR_INPUT, NRF_GPIO_PIN_INPUT_CONNECT, NRF_GPIO_PIN_NOPULL, NRF_GPIO_PIN_S0S1, NRF_GPIO_PIN_NOSENSE);

Then I inizialize the GPIOTE:

nrf_drv_gpiote_init();

Finally I access the pin with:

uint32_t sig_ok;

sig_ok=nrf_gpio_pin_read(SIG_OK);

Is this all correct??

Thanks a lot

Francesco

I found that gpiote initialization in this case in not needed.. morevoer, maybe it is easier to configure the input using:

nrf_gpio_cfg_input(SIG_OK,NRF_GPIO_PIN_NOPULL);

Thanks
