Hello,

I cannot use “lv_led_set_color” on version 8.3
I have created a led:

/Create a ADX_Create_Label_Bool style./
lv_style_init(&ADX_style_label_bool_r);
lv_style_set_height(&ADX_style_label_bool_r,40);
lv_style_set_width(&ADX_style_label_bool_r,40);
lv_style_set_bg_color(&ADX_style_label_bool_r,lv_palette_main(LV_PALETTE_GREEN));
lv_style_set_bg_opa(&ADX_style_label_bool_r,255 );

and

static lv_obj_t * ADX_Create_Label_Bool(lv_obj_t * parent, lv_style_t * ADX_style, int x, int y, float value, lv_event_cb_t event_cb)
{
/Create label and use the new styles/
static lv_obj_t * Led;
Led = lv_led_create(parent);
lv_obj_remove_style_all(Led); /Remove the styles coming from the theme/
lv_obj_add_style(Led, ADX_style, LV_STATE_DEFAULT);
lv_obj_align(Led, LV_ALIGN_CENTER, 0, 0);
//lv_led_set_color(Led,lv_palette_main(LV_PALETTE_RED));
lv_led_set_brightness(Led, 255);
lv_obj_set_x(Led, x);
lv_obj_set_y(Led, y);
lv_led_on(Led);

return Led;

}

				if (*ValueToDisplay==0)
				{
					lv_led_set_color(led,lv_palette_main(LV_PALETTE_RED));
				}
				else
				{
					lv_led_set_color(led,lv_palette_main(LV_PALETTE_GREEN));
				}

But the color of the led do not change.
I call lv_task_handler() peridodically.

The other label of the screen are updated.
Thank you for your help

Best regard
