Hi,

I see.

Thank you for your assistance.

Hi,

I looked a bit more into the code. Unfortunately, it seems like the Audio application's button_handler module only supports GPIO port 0. So you either need to modify this module yourself, or wait until we add support for this.

Hi,

It works.Thank you very much.

But after I add BUTTON_6 to my button configure and flash to the nrf5340 audio dk board,it occurrs error:

Here is the code I add:

const static struct btn_config btn_cfg[] = {
	{
		.btn_name = STRINGIFY(BUTTON_VOLUME_DOWN),
		.btn_pin = BUTTON_VOLUME_DOWN,
		.btn_cfg_mask = DT_GPIO_FLAGS(DT_ALIAS(sw0), gpios),
	},
	{
		.btn_name = STRINGIFY(BUTTON_VOLUME_UP),
		.btn_pin = BUTTON_VOLUME_UP,
		.btn_cfg_mask = DT_GPIO_FLAGS(DT_ALIAS(sw1), gpios),
	},
	{
		.btn_name = STRINGIFY(BUTTON_PLAY_PAUSE),
		.btn_pin = BUTTON_PLAY_PAUSE,
		.btn_cfg_mask = DT_GPIO_FLAGS(DT_ALIAS(sw2), gpios),
	},
	{
		.btn_name = STRINGIFY(BUTTON_4),
		.btn_pin = BUTTON_4,
		.btn_cfg_mask = DT_GPIO_FLAGS(DT_ALIAS(sw3), gpios),
	},
	{
		.btn_name = STRINGIFY(BUTTON_5),
		.btn_pin = BUTTON_5,
		.btn_cfg_mask = DT_GPIO_FLAGS(DT_ALIAS(sw4), gpios),
	},
	{
		.btn_name = STRINGIFY(BUTTON_6),
		.btn_pin = BUTTON_6,
		.btn_cfg_mask = DT_GPIO_FLAGS(DT_ALIAS(bkey), gpios),
	}
};

How to enable this pin?

Hi,

Try adding

#include <soc.h>

to the file where you have this:

enum button_pin_names {
	BUTTON_VOLUME_DOWN = DT_GPIO_PIN(DT_ALIAS(sw0), gpios),
	BUTTON_VOLUME_UP = DT_GPIO_PIN(DT_ALIAS(sw1), gpios),
	BUTTON_PLAY_PAUSE = DT_GPIO_PIN(DT_ALIAS(sw2), gpios),
	BUTTON_4 = DT_GPIO_PIN(DT_ALIAS(sw3), gpios),
	BUTTON_5 = DT_GPIO_PIN(DT_ALIAS(sw4), gpios),
	BUTTON_6 = NRF_DT_GPIOS_TO_PSEL(DT_ALIAS(bkey), gpios),
};

Hi,

I do pristine build every time, but the error still occurs.

I am using nrf5340_audio application, and my overlay file name is nrf5340_audio_dk_nrf5340_cpuapp.overlay.

I compared your test sample with my audio application, and there is no difference in the BUTTON_6 part.

Hi,

Try doing a pristine build.

It works fine here testing with NCS 2.2.0

My test sample:

Thank you for your reply.
But it doesn't work，I get an error during building: identifier 'DT_N_S_buttons_S_button_6' undeclared here (not in a function).

Hi,

You can use NRF_DT_GPIOS_TO_PSEL() instead.

BUTTON_6 = NRF_DT_GPIOS_TO_PSEL(DT_ALIAS(bkey), gpios),
