            lv_obj_set_size(obj, 399, 195);
            //lv_obj_set_pos(obj, 36, 2);
            //lv_obj_set_size(obj, 100, 40);
            lv_btnmatrix_set_one_checked(obj, true);
            lv_obj_add_event_cb(obj, event_handler_btn_matrix, LV_EVENT_ALL, NULL);
            lv_obj_add_style(obj, get_style_blue_button_MAIN_DEFAULT(), LV_PART_ITEMS | LV_STATE_DEFAULT);
            lv_obj_add_style(obj, get_style_gold_button_MAIN_CHECKED_PRESSED(), LV_STATE_CHECKED); // Apply to the items (buttons)
            
            static const char *map[] = {"Microphone", "SD Drive","\n", "BlueTooth", "YouTube","\n", "Spotify",
                NULL,
            };
            
            lv_buttonmatrix_set_map(obj, map);
            lv_obj_set_style_border_width(obj, 0, LV_PART_MAIN | LV_STATE_DEFAULT);
            lv_buttonmatrix_set_button_ctrl(obj, 0, LV_BUTTONMATRIX_CTRL_CHECKABLE);
            lv_buttonmatrix_set_button_ctrl(obj, 1, LV_BUTTONMATRIX_CTRL_CHECKABLE);
            lv_buttonmatrix_set_button_ctrl(obj, 2, LV_BUTTONMATRIX_CTRL_CHECKABLE);
            lv_buttonmatrix_set_button_ctrl(obj, 3, LV_BUTTONMATRIX_CTRL_CHECKABLE);
            lv_buttonmatrix_set_button_ctrl(obj, 4, LV_BUTTONMATRIX_CTRL_CHECKABLE);

            lv_buttonmatrix_set_map(obj, map);
            lv_obj_set_style_border_width(obj, 0, LV_PART_MAIN | LV_STATE_DEFAULT);
            lv_buttonmatrix_set_button_ctrl(obj, 0, LV_BUTTONMATRIX_CTRL_CHECKABLE);
            lv_buttonmatrix_set_button_ctrl(obj, 1, LV_BUTTONMATRIX_CTRL_CHECKABLE);
            lv_buttonmatrix_set_button_ctrl(obj, 2, LV_BUTTONMATRIX_CTRL_CHECKABLE);
            lv_buttonmatrix_set_button_ctrl(obj, 3, LV_BUTTONMATRIX_CTRL_CHECKABLE);
            lv_buttonmatrix_set_button_ctrl(obj, 4, LV_BUTTONMATRIX_CTRL_CHECKABLE);
