#if (TP_TEST_FUNC == ENABLE)
static Ux_RECT tp_coord = {0,0, 0, 0};

PUx_RECT endev_get_tp_coord(void)
{
    return (PUx_RECT)&tp_coord;
}
#endif

    #if (TP_TEST_FUNC == ENABLE)
    int x = endev_get_tp_coord()->x1;

    lv_label_set_text_fmt(HomeBar_objs.tp_test_str, "( %d - %d )", x,y);
    #endif

换一种写法

#if (TP_TEST_FUNC == ENABLE)
static Ux_RECT tp_coord = {0,0, 0, 0};

void  endev_get_tp_coord(PUx_RECT data)
{
    data->x1 = tp_coord.x1;
    data->y1 = tp_coord.y1;
}
#endif

---

    #if (TP_TEST_FUNC == ENABLE)
    Ux_RECT tp_data = {0};
    endev_get_tp_coord(&tp_data);
    lv_label_set_text_fmt(HomeBar_objs.tp_test_str, "( %d - %d )", tp_data.x1, tp_data.y1);
    #endif

另一种报错

ui_home.c:1161:5: error: unknown type name ‘Ux_RECT’
 1161 |     Ux_RECT tp_data = {0};
      |     ^~~~~~~

估计是编译器找不到数据的类型了
