How to cycle through keyboard widget keys using an encoder?

Hi @Serg,

Thank you to open this topic. There are steps:

  • Create a group and assigned the encoder.
  • Add the keybord as widget to the group
  • Configure the encode mode (Navegation and Edit mode).

Once in edit mode, LV_KEY_RIGHT/UP/LEFT/DOWN navigate among the keyboard buttons, and LV_KEY_ENTER (pressing the encoder) presses the selected button

lv_group_t * g = lv_group_create();

lv_indev_t * indev = lv_indev_create();
lv_indev_set_type(indev, LV_INDEV_TYPE_ENCODER);
lv_indev_set_read_cb(indev, your_encoder_read);
lv_indev_set_group(indev, g);

lv_obj_t * kb = lv_keyboard_create(lv_screen_active());
lv_group_add_obj(g, kb);

Thank you, halyssonJr
Yes, these buttons work, but I thought rotating the encoder was equivalent to pressing these buttons.
I had to do it this way:

void encoder_read(lv_indev_t *indev, lv_indev_data_t *data)
{
	data->enc_diff = (int16_t) EncoderSel_update();
	tmp = data->enc_diff;
	 if (data->enc_diff < 0)
		 data->key = LV_KEY_LEFT;
	 else if (data->enc_diff > 0)
		 data->key = LV_KEY_RIGHT;
	 else
		 data->key = GetNumKey();
	/*Get the last pressed or released key*/
	if (data->key >= 0)
		data->state = LV_INDEV_STATE_PRESSED;
	else
		data->state = LV_INDEV_STATE_RELEASED;
}
