how to modify the initial polarity for LED?

[gercer]

Hello.

I am working with a custom board. I have been wondering how to change the default polarity for a pin? I need LED_1 to have a polarity and the other 3 LEDs to have the opposite. When I go to sleep mode my LED turns on and i wanna modify that.

Thanks!

Hi Gerardo,

You could change it in the Register of the pin.

You could also check out the Pin Change Interrupt example and use that as reference.

 

(You could also take a look at the Board Support Package)

Thanks!

After reading the example I noticed I had to add this code:

nrf_drv_gpiote_out_config_t out_config = GPIOTE_CONFIG_OUT_SIMPLE(false);

err_code = nrf_drv_gpiote_out_init(LED_1, &out_config);
APP_ERROR_CHECK(err_code);
