Hi,
Designer does not support 180 degree rotations. You may be able to rotate your display 180 degrees through hardware configuration. The hw config solution should be investigated first, because this software solution is very inefficient: you rotate the framebuffer but at a significant performance cost. It is an expensive operation since pixels must be swapped on both X and Y axis. It leads to very inefficient RAM accesses. Here is a link to another community post where they talk about it. You have some sample code as well.
