i already read the documentation. this function give 1 if the logic level is high and 0 for logic level low.

[quote userid="80339" url="~/f/nordic-q-a/49420/how-to-get-input-from-gpio/197887"]i do as you tell me.[/quote]

I didn't tell you anything; I asked you to study the documentation - have you done that?

[quote userid="80339" url="~/f/nordic-q-a/49420/how-to-get-input-from-gpio/197887"]the status is printed 0 [/quote]

So what did you expect?

Again, what does the documentation tell you?

It's no use just randomly throwing function calls together - you need to understand what those functions do!

i do as you tell me.

nrf_gpio_cfg_input(01,NRF_GPIO_PIN_NOPULL);

SEGGER_RTT_printf(0,"status%d\n",nrf_gpio_pin_read(01));

i write like this but the status is printed 0 on segger rtt .

this not print high logic level.

thank you.

[quote userid="80339" url="~/f/nordic-q-a/49420/how-to-get-input-from-gpio/197618"]nrf_gpio_pin_get([/quote]

So what does the documentation for that function tell you?

How about nrf_gpio_pin_read() ?

while( true )
{
    if( button is pressed )

        ++variable;
    }
}

thank you.

Have you tried the "pin_change_int" example?

fenil.patel — Fri, 05 Jul 2019 11:09:41 GMT

i look the bsp example. but nothing helped.

awneil — Fri, 05 Jul 2019 11:05:26 GMT

Have you looked at the examples in the SDK ?
