  1. 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.
  2. Good question. I used STMCube to create the framework of this code. It seems likely this is the issue. Investigating, Thanks
  3. 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. STM32F4_freertos.zip
  4. 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....
  6. We forgot to add in DMA2D option for the STM32F429 Cortex M4 CP. Thanks.
  7. Thanks for the quick response. Will check those areas.
  8. 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.
  9. 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

    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.

    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. gfxconf.h defs #define GFX_USE_OS_FREERTOS GFXON #define GFX_OS_HEAP_SIZE 40960 #define GFX_OS_NO_INIT GFXON #define GFX_USE_GDISP GFXON #define GDISP_NEED_VALIDATION GFXON #define GDISP_NEED_CLIP GFXON #define GDISP_NEED_CIRCLE GFXON #define GDISP_NEED_CONTROL GFXON #define GDISP_NEED_MULTITHREAD GFXON #define GDISP_NEED_TEXT GFXON #define GDISP_INCLUDE_FONT_DEJAVUSANS12 GFXON #define GDISP_TOTAL_DISPLAYS 1 #define GDISP_DRIVER_LIST GDISPVMT_STM32LTDC #define GDISP_PIXELFORMAT GDISP_PIXELFORMAT_RGB888 #define GFX_USE_GWIN GFXON #define GWIN_NEED_WINDOWMANAGER GFXON #define GWIN_NEED_WIDGET GFXON #define GWIN_NEED_BUTTON GFXON #define GFX_USE_GEVENT GFXON #define GFX_USE_GTIMER GFXON #define GFX_USE_GQUEUE GFXON #define GQUEUE_NEED_ASYNC GFXON #define GFX_USE_GINPUT GFXON #define GINPUT_NEED_MOUSE GFXON 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': C:\Users\fishe\Atollic\TrueSTUDIO\STM32_workspace_9.0\STM32F4\Debug/..\uGFX\src\gdisp/gdisp.c:601: undefined reference to `GDISPVMT_STM32LTDC' uGFX\src\gfx_mk.o: In function `_gmouseInit': C:\Users\fishe\Atollic\TrueSTUDIO\STM32_workspace_9.0\STM32F4\Debug/..\uGFX\src\ginput/ginput_mouse.c:669: undefined reference to `GMOUSEVMT_OnlyOne' I'm in the process of paying for a commercial license and support. Any help u can give me would be greatly appreciated.
