  Hi Christoph,

  The Bridgetek FT801 EVE Series Programmer Guide describes a "CMD_ROTATE" command on page 227 that may help answer your question.  https://brtchip.com/wp-content/uploads/Support/Documentation/Programming_Guides/ICs/EVE/FT800_Series_Programmer_Guide.pdf 

  Best Regards,

  Ted

  Hi Ted, 

  i found the "CMD_ROTATE" command but i think this is not i´m looking for. 

  on Page 37, there is a register "REG_ROTATE". Maybe this is what i need. I installed the screen upside down and that´s why i need to rotate all not only a matrix or picture. 

  but how can i write to registers?

  thanks for your help

  Best Regards, 

  Chris

   

   

  EDIT: i have solved the problem by writing a new function "RotateScreen(void)" in the FT_GC.h file. 

  thansk a lot, 

  Christoph
