STM32F746G-Disco Bd, doesn't display correctly in portrait mode

[JJoha.2]

I started a project from scratch in CubeMX. 

and the set TouchGFX for portrait as :

Middleware->Graphics->TouchGFX, changed width : 272 and Height : 480. 

In TouchGFX designer it displays correctly as Portrait(see PortraitFromTouchGFX).PNG) but when I compiled using IAR and deployed it on the target bd, it doesn’t display correctly (see From STM32F746-Disco Display.jpg )

In Hal.hpp : It automatically sets the display orientation based on width/height, so I don't think I need to do anything else. (Changing LTDC etc)

 HAL(DMA_Interface& dmaInterface, LCD& display, TouchController& touchCtrl, uint16_t width, uint16_t height) :

    dma(dmaInterface),

    lcdRef(display),

    touchController(touchCtrl),

    mcuInstrumentation(0),

    buttonController(0),

    taskDelayFunc(0),

    frameBuffer0(0),

    frameBuffer1(0),

    frameBuffer2(0),

    refreshStrategy(REFRESH_STRATEGY_DEFAULT),

    fingerSize(1),

    lockDMAToPorch(true),

    touchSampleRate(1),

    mcuLoadPct(0),

    vSyncCnt(0),

    vSyncForFrame(1),

    vSyncCompensationEnabled(false),

    clientDirty(false),

    swapRequested(false),

    lastTouched(false),

    updateMCULoad(0),

    cc_begin(0),

    displayOrientationChangeRequested(false)

  {

    instance = this;

    DISPLAY_WIDTH = width;

    DISPLAY_HEIGHT = height;

    DISPLAY_ROTATION = rotate0;

    FRAME_BUFFER_WIDTH = DISPLAY_WIDTH;

    FRAME_BUFFER_HEIGHT = DISPLAY_HEIGHT;

    nativeDisplayOrientation = ((width >= height) ? ORIENTATION_LANDSCAPE : ORIENTATION_PORTRAIT);

  }

I'll just post it here for others see. Let me know if it helps!

Martin,

Thanks. I'll look into that.

Sounds good. It's based on TouchGFX 4.10.0. I couldn't see what version you were using from this thread.

Hi，Martin

I'm using TouchGFX 4.13.0 Designer, and add "​screen_orientation := -rotate90" to the file(config/gcc/app.mk), it didn't work.

then, i found the "image_configuration" in the file (.config), and add "screen_orientation := -rotate90", as shown in the figure below.

when generated code in TouchGFX Designer, i got error information "Unknown option 'screen_orientation' in configuration file",

so, how should I add​  the statement "screen_orientation"??

Thanks
