Ok, I see. How have you configured your board files? See this link. Have you based your project on a sample from NCS? The code you have insterted, is this something you have from NCS?

Kind regards,

No, i run the project on my own board, in this board, i use p07 as an interrupt signal pin, However, when the interrupt was triggered, I found that it was actually handled by the button handler function, i want to use my custom key, is not use the default button key(P06,P07,P08P,P09), because these pins have already been used for other purposes.

static void button_handler(u32_t button_state, u32_t has_changed)
{
	int err_code;

	u32_t buttons = (button_state & has_changed);

	keycode = has_changed;
	keytype = button_state/has_changed;
	
	switch(keytype)
	{
	case KEY_DOWN:
		k_timer_start(&g_long_press_timer_id, K_MSEC(TIMER_FOR_LONG_PRESSED), K_NO_WAIT);
		break;
		
	case KEY_UP:
		k_timer_stop(&g_long_press_timer_id);
		break;

	case KEY_LONG_PRESS:
		break;
	}

	key_event_handler(keycode, keytype);
}

static void long_press_timer_handler(struct k_timer *timer)
{
    key_event_handler(keycode, KEY_LONG_PRESS);
}

void key_init(void)
{
	int err;

	printk("key_init\n");
	
	err = dk_buttons_init(button_handler);
	if (err)
	{
		printk("Could not initialize buttons, err code: %d\n", err);
		return;
	}

	k_timer_init(&g_long_press_timer_id, long_press_timer_handler, NULL);
}

Hello,

You are using a nRF9160DK to run your custom project or a sample project? P06,P07,P08,P09 are controlled by board controller.

Kind regards,
