  • Movie colors issue

    Hi Segger team and users,

    I have a problem with colors while running stemwin with ili9488 controller on a 320*480 TFT,
    the colors are ok while running static images or colors , I run the
    COLOR_ShowColorBar demo and I see that colors are correct.
    but the problem starts to appear when I run videos , I always see the yellow
    color turned to blue.
    this problem only happens when running videos , I used the MOVIE_ShowFeatures Demo as a test.
    I use those settings as suggested by segger.
    color conversion : GUICC_565
    flex color driver : GUIDRV_FLEXCOLOR_F66709
    pfmode : GUIDRV_FLEXCOLOR_M16C0B16
    I am doing the interface with stm32f407 processor while defining memory like that
    #define GUI_NUMBYTES (1024) * 100
    my heap and stack are configured to be 2000 byte each.
    and I tried several initialization sequences from forums and also from the TFT supplier , but
    got same output.
    Heres' the current initialization sequence.

    I tried to minimize the memory seen by stemwin so that I would minimize the memory requirements ,but I got same results
    just smaller screen
    #define XSIZE_PHYS 200
    #define YSIZE_PHYS 200
    please if you need any more information to help me out solving this problem let me know,
    Thanks a lot.
    Amr.
