I use LPC1850 with display LCD TFT 5,7” (640 X 480),DISPLAY_DRIVER GUIDRV_LIN_32
and try to change display orientation
with #define GUIDRV_LIN_OSY_24
or #define DISPLAY_ORIENTATION (GUI_SWAP_XY | GUI_MIRROR_Y)
or #define LCD_SWAP_XY 1
#define LCD_MIRROR_Y 1
they are did work.
using GUI_SetOrientation(GUI_SWAP_XY | GUI_MIRROR_Y); it is ok,
but display flicker while displaying the image ?
Kindly give any suggestion.
