How to define PIN in nrf52?

[shadab]

I want to used p1.01 and p1.2 and p0.13,so how to defined it.

I do like 

#define led0 13 to used pin p0.13 its working but how to define pin P1.01 and all

Hi Shadab,

Just add 32 to the pin number of GPIO1.

hi charlie, I try on nrf52833 DK board but its not working

Hi Shadab,

Not sure how you test this, anyway let's find a common ground.

In nRF5_SDK_17.0.2, there is a simple example on examples\peripheral\blinky. Make sure the original blink example works, then you can modify it like below to verify if pins at GPIO1 works or not. 

    /* Configure board. */
    //bsp_board_init(BSP_INIT_LEDS);
    nrf_gpio_cfg_output(NRF_GPIO_PIN_MAP(1,10));

    /* Toggle LEDs. */
    while (true)
    {
        //for (int i = 0; i < LEDS_NUMBER; i++)
        //{
            //bsp_board_led_invert(i);
            nrf_gpio_pin_toggle(42);
            nrf_delay_us(0.5);
        //}
    }

Here both NRF_GPIO_PIN_MAP(1,10) and 42 points to oin1.10. You should see the pin toggle with the help of a logic analyzer or oscilloscope.

Best regards,

Hi charlie !! not working 

[Charlie]

I am working. ;-) 

Could explain what you have done by far? Did you check the original example with a logic analyzer or oscilloscope, what does it look like?
