[FreeRTOS Semaphore Create Mutex]

Good suggestion thanks

[FreeRTOS Semaphore Create Mutex]

Thanks for the direction.  I read the suggested link many times and changed the code to match this recommendation and still no progress.  I know this issue is related to FreeRTOS.  I have tried using uGFXMain as well. but no change in behavior.    

I have a commercial license and I am good to pay for support.  Would be appreciative if I could get help with this issue  we can get on with the actual development.

Thanks.

[FreeRTOS Semaphore Create Mutex]

Good question.  I used STMCube to create the framework of this code.  It seems likely this is the issue.  Investigating,  Thanks 

[FreeRTOS Semaphore Create Mutex]

I am using the STM32F429i-Eval1 dev kit.  Working on a home appliance that has a LCD touch panel embedded.  I am using trueStudio 9.0 as the IDE.

During gfxInit(), I have traced through the init functions to where gwin_wm.c fun gwinUpdate calls gfxSemInit.  In gfxSemInit the call to xSemaphoreCreateCounting gets stuck when limit=1 and val = 1.  When limit = 0, the functions executes.

Cannot figure out why this is happening.  Probably a setting isn't set correctly. 

Any help is appreciated. 

My project is attached.

[STM32F429XX Fails to draw/show gdispDrawBox]

The project is attached to this topic.

I believe I have the project setup correctly.  Although I'm no expert on all the LCD panel settings.  I am using the STM32F429i-Eval1 dev kit.  Working on a home appliance that has a LCD touch panel embedded.  I am using trueStudio 9.0 as the IDE.

I debugged the gdispDrawBox all the way through completion and it seems to executed with no failures.  I have GDISP_NEED_AUTOFLUSH = TRUE in gfxconf.h.  

Any help is appreciated.

thanks... helpful....

[fillArea on startup drawing logo never returns]

We forgot to add in DMA2D option for the STM32F429 Cortex M4 CP.  Thanks.

[fillArea on startup drawing logo never returns]

Thanks for the quick response.  Will check those areas.  

[Arranging art Elements]

I have multiple ui elements in a container.  How do I arrange them front to back?  I see there is a "raise" option, but it doesn't seem to stick if you touch the ui element.

[fillArea on startup drawing logo never returns]

Having a failure in gdispGFillArea() call for displaying default logo.

gdispInit() -> vmt->postinit(pd) -> gdispGFillArea(g, x+p[0]*w, y+p[1]*w, p[2]*w, p[3]*w, GDISP_STARTUP_LOGO_COLOR) -> fillArea(g)

In gdisp_lld_STM32LTDC.c, function gdisp_lld_fill_area(GDisplay* g), the following while loop never gets resolved.

 // Wait until DMA2D is ready
        while(DMA2D->CR & DMA2D_CR_START);

DMA2D = ((DMA2D_TypeDef *)((0x40000000U + 0x00020000U) + 0xB000U))

DMA2D_CR_START = (0x1U << (0U))

 

Any help is appreciated.

gfxconf.h

[STM32F4291-Eval]

Thanks for the quick response.  Will use code boxes for future support questions.  

I did check out and read and followed the Eclipse guide.  Found some of these setup parameters in the GTXConf file confusing with no prior background with this tool set.

[STM32F4291-Eval]

I am extremely new at setting up uGFX for display, touch and UX.  I am using trueStudio IDE and have a project using a HAl built from STMCube as a starting point.  I have the project building to a point, but not to completion.  

I am confused on how to integrate LCD panel and touch glass using gfxconf.h and include files.

I have stm32_ltdc.h in my Inc folder

I have placed in gfx.mk this include -- include $(GFXLIB)/drivers/gdisp/STM32LTDC/driver.mk

I see this build error -- 

 

uGFX\src\gfx_mk.o: In function `_gdispInit':

I'm in the process of paying for a commercial license and support.  

Any help u can give me would be greatly appreciated.
