have read the older thread on this topic. There was some information how to change some code in initlcd.h of the TFT-Driver in UTFT library. This was shown for other driver (ssd1963)
Unfortunately I do not know which code I would have to change for my driver (hx8352a).
Display is a 3.2" WD TFT from ITead which I can not rotate in my case. So I would have to rotate the output for 180 degrees.
