I don't know, perhaps put some more effort into the question. Did you try anything or just throw your hands up? Do you have code programmed? Does it work? If you step through, does it behave as expected? Do signals on the line look as expected per the datasheet? We need a point of reference in order to help debug.

I tried anything and in every way it didnt worked. I dont know, if the signals are right, cuz I dont have a logic analyzer
