error: #513: a value of type "int" cannot be assigned to an entity of type "lv_obj_t *"

这个错误是由于将一个int类型的值赋给了一个lv_obj_t*类型的变量引起的。根据引用\[1\]和引用\[2\]的描述，这个错误通常发生在函数返回值无法赋值给对应变量的情况下。根据引用\[3\]的描述，可能的原因有两个：第一，函数返回值是int型，而变量是lv_obj_t*类型；第二，调用函数的文件没有包含函数的声明。要解决这个错误，你可以检查一下函数的返回值类型和变量的类型是否匹配，并确保在调用函数之前包含了函数的声明。
