  • STEMWIN windows object breakdown

    Hello.

    On STM32F429-DISCO board, i am replaced LCD to 5" one. QWVGA 800-480 size lcd works fine. (LTDC, 8MB SDRAM, DMA2D)

    I am testing emWIN objects on LCD with guibuilder.exe

    Checkbox, radio and slider object are breaking down when i touched them.

    Also, creating windows is complating with some runtime problems. Window objects (button, text, image ..) can be shown first, but window's background color is filling slowly.

    - After calling creating window, window's objects shown before than window's back color. From up to down, it is slow. I tried to incrase GUI RAM size by using SDRAM and creating window slowed. BG color filling is over 3 seconds for 24bit 800*480 lcd.

    I controlled thar DMA2D init and it's interrupts on debug, i could not find any issue.

    The working code and windows created by emWin's gui tool. There is no another change. (expect LCD pins and configs, LCD clock timings for LTDC )
  • Hello,

    Could you please tell me what is meant with "breaking down"?

    Please note that "some runtime problems" does not include enough details to give a hint for solving problems.

    Have you been able to determine the performance bottle neck?

    Best regards,
    Adrian
