How Can I Use Dır_Mask Pin Read?

[rraa]

I have a lot of pin_read function. How can i set all port one line? for example P1OUT = (P1.01 | P1.02 | P1.03) or P1IN = (P1.01 | P1.02 | P1.03) I dont know how to use pin mask? 

here is my code and header file;

Note that

if(nrf_gpio_pin_read(SATIR_1)  || nrf_gpio_pin_read(SATIR_2))

is not completely identical to

if (NRF_GPIO->IN & ((1UL << SATIR_1) | (1UL << SATIR_2)))

because the code below only reads the IN register once.

One can set the output value of several pins using NRF_GPIO->OUT, but you can only set the mode of each pin individually, as each has its own mode register.

Hello everyone;

thanks for answerTurbo J I tried this and it worked. Then i changed someting in my code. But pins out it was not set high. I want to know where is my mistake?

unsigned char sutunlar;

void Sutun_Cikislari(void)
{
  nrf_gpio_cfg_output(LED_DENEME);
  sutunlar = NRF_GPIO->OUT & ((1UL << SUTUN_1) | (1UL << SUTUN_2) | (1UL << SUTUN_3));
//  nrf_gpio_cfg_output(SUTUN_1);
//  nrf_gpio_cfg_output(SUTUN_2);
//  nrf_gpio_cfg_output(SUTUN_3);
//  nrf_gpio_pin_set(SUTUN_1);
//  nrf_gpio_pin_set(SUTUN_2);
//  nrf_gpio_pin_set(SUTUN_3);
  nrf_gpio_pin_set(sutunlar);
  nrf_gpio_cfg_input(SATIR_1, NRF_GPIOTE_POLARITY_LOTOHI);
  nrf_gpio_pin_read(SATIR_1);
  nrf_gpio_cfg_input(SATIR_2, NRF_GPIOTE_POLARITY_LOTOHI);
  nrf_gpio_pin_read(SATIR_2);

You are trying to put waaay more than 8 bits into your "unsigned char sutunlar;" variable. Try uint32_t type.

[rraa]

uint32_t sutunlar;

void Sutun_Cikislari(void)
{
  nrf_gpio_cfg_output(LED_DENEME);
  sutunlar = NRF_GPIO->OUT & ((1UL << SUTUN_1) | (1UL << SUTUN_2) | (1UL << SUTUN_3));
//  nrf_gpio_cfg_output(SUTUN_1);
//  nrf_gpio_cfg_output(SUTUN_2);
//  nrf_gpio_cfg_output(SUTUN_3);
//  nrf_gpio_pin_set(SUTUN_1);
//  nrf_gpio_pin_set(SUTUN_2);
//  nrf_gpio_pin_set(SUTUN_3);
  nrf_gpio_pin_set(sutunlar);
  nrf_gpio_cfg_input(SATIR_1, NRF_GPIOTE_POLARITY_LOTOHI);
  nrf_gpio_pin_read(SATIR_1);
  nrf_gpio_cfg_input(SATIR_2, NRF_GPIOTE_POLARITY_LOTOHI);
  nrf_gpio_pin_read(SATIR_2);
  while(1)
  {
    if (NRF_GPIO->IN & ((1UL << SATIR_1) | (1UL << SATIR_2)))
     {
      nrf_gpio_pin_set(LED_DENEME);
     }
    else
     {
      nrf_gpio_pin_clear(LED_DENEME);
     }
  }
}

here is my new code but it didn't happend. 

this line is correct?

sutunlar = NRF_GPIO->OUT & ((1UL << SUTUN_1) | (1UL << SUTUN_2) | (1UL << SUTUN_3));

[Turbo J]

Why don't you check this yourself with a debugger? I have absolutely no idea what this line is supposed to do. It has correct C syntax and masks out everything but the 3 port bits.

I will try.
