STM32 MCUs TouchGFX and GUI

Hi everyone!I'm trying for the first time to create a project using TouchGFX without using the Designer. My short term is objective is as simple as to see in the screen numbers generated by a function created in main.c or model.cpp.1) Is there a template of files and folders to implement touchgfx from scratch?2) What are the configurations in the .ioc in order to use the screen and touchgfx?I've already installed and activated TouchGFX in the Mx/middleware but I had several build errors due to non-existing or incomplete files.I'm using CubeIDE and the stm32h750B_dk board.Thank you in advance for all your support.Kind Regards,TJAttachements: .ioc configurations, file tree and compilation errors

I recently acquired the STM32F469NI-Discovery board as it purported to support most of the functions that I wanted - GUI, USB OTG, SD card, etc. However, on bringing it up, it did not load and remained blank. (Customer support has not been supportive in getting the demo software loaded.) I have been able to run simple TouchGFXDesigner projects with ST332Cube. But, when I try to add simple functionality, I find that what's in he .ioc file does not agree with what's on the board (in the schematic). The best I have been able to do is determine that the promised sample code is not available.Can someone recommend a newer board that has better support? The larger the display, the better. I can work with almost any daughter board configuration (Arduino, etc.) as long as it is well documented. A primary requirement is that the source code for the examples be easily accessed.For those interested, this is to be used as a front-end controller for custom lab test equipment. The GU

Hi,I want to know how I can implement a generic SPI Display with a ST7789V driver with TouchGFX. I saw several tutorials but no of these was clear for me. I know that I must setup TouchGFX with generic display, get a Display Driver and then add some code to TouchGFX. But what does this mean in detail?Can someone please explain to me step by step how to do the implementation?BRMatthias

Please help me.

Hi I'm just starting to use TouchGFX designer, with a background in other UI design programs, and one thing I'm frustrated about is the lack of the ability to align and distribute assets on a screen. I do appreciate the snapping that happens but if I need to distribute a number of objects evenly or just batch align them all with one click, it becomes bit of a pain to manually type x and y locations for each one. I guess it's not that big of a deal, but just a feature that I feel is missing from a UI design software that others have and feels like TouchGFX is behind in this aspect. Also there is a bug in 4.25.0 where if you have multiple objects selected and then move them, when you deselect them by clicking elsewhere, the mouse automatically latches to the "box select" mode.

I have created a ui to that i am able to upload on the custom board(STM32H750VBT6) which i can successfully Debugging using IDE but display is empty.I dont know where I am wrong.I attached the library that I am using below.I have taken library from this GitHub with this pinout

Hi,is it possible to select just the CPU and connect any display (e.g. via MIPI DSI)?Best regards,Achim

I've installed TouchGFX . When I try to create a project, TouchGFX crashes at 88% and simply closes. When I checked the TouchGFXDesigner.log file the error is System.IO.FileLoadException: Failed to load native freetype library!same issue?  Any idea how I can fix this?

Hello,is it possible to create a dotted line using Canvas Widget line?Thanks

Hi Team,I’m currently working on a project involving the TouchGFX interface with an internal clock configured at 480 MHz. I’ve created a custom TouchGFX project using STM32CubeMX and successfully brought up both QSPI and SDRAM, verifying their functionality independently.Following the guidelines from TouchGFX Seminar -3, I proceeded to enable TouchGFX through CubeMX. I've attached screenshots showing my LTDC, DMA2D, Clock, and TouchGFX configurations for your reference.Project Details:MCU: STM32H750IBT6Display: 12.1-inch panel supporting RGB888LVDS Driver: DS90C385AMTX_NOPBInitially, with a simple background and the default designer gauge, everything worked fine.However, when I customized the gauge's background and needle graphics, I started encountering errors, including:TouchGFX rendering err

Hello all,I created an application with a 800x480 FSMC 16 Bits TFT screen (SSD1963 driver) STM32F429 CPU, I would like to create my screens with TouchGFX instead of creating lines of code on CubeIde, is it possible? If so, what should I take into account in my Cube Ide project?, I did project tests with TouchGFX (blank screen) and during compilation, there are errors that I cannot correct, (my project works without TouchGFX files) can someone help me ?Best regardsSeb 

Hi Guys.I want to set textarea. I created the new texts.         And program is here;Model.cppvoid Model::tick() { static uint32_t counter = 0; const uint32_t updateInterval = 5; touchgfx::TypedTextId Bat4TextId; counter++; if (counter >= updateInterval) { switch (BAT4_CAN_Rx.fields.BAT4_State) { case CHARGE_MODE: Bat4TextId = T_CHARGE; break; case RELAXING_MODE: Bat4TextId = T_RELAXING; break; case DISCHARGE_MODE: Bat4TextId = T_DISCHARGE; break; case READY: Bat4TextId = T_READY; break; ca

Hi,I've installed TouchGFX following the instruction at https://support.touchgfx.com/docs/introduction/installation on a completely new installation of windows 10. When I try to create a project, TouchGFX crashes at 88% and simply closes. When I checked the TouchGFXDesigner.log file the error is System.IO.FileLoadException: Failed to load native freetype library!Any idea how I can fix this?Please see attached log file.Thank for your help. Looking forward to get the designer working.Richard

Hello!Our project is supposed to use C++17 features.When linking C++17 compiled objects against TouchGFX Designer's distributed binaries (eg: touchgfx_core.a), linkage fails, because the touchgfx binaries appear to be compiled against the c++14 standard, not c++17.Compiling with IAR 9.30.1, having the C++17 compiler flag ("libc++" in IAR parlance) set, the following error is thrown during linkage.  Error[Li009]: runtime model conflict: Module ListLayout.o(touchgfx_core.a) specifies that '__CPP_Library' must be 'DLib', but module [hidden-name].o has the value 'libc++'   We are using TouchGFX 4.23.2 which according to the date of

Hi,Any idea how I can build my touchgfx project on a CI/CD. The goal is only to verify if the simulator is still building (or it's working) Thank you 

Hello.I am new to TouchGFX and have been learning it over the last few weeks. I am able to generate an application with multiple screens, and swap screen utilizing the TouchGFX designer actions & interactions. I have a screen, called Screen4, that is a testing screen to test out different iconographies:Within that Screen4 I have two actions:

I have a TouchGFX Designer project that I setup in a Windows environment. In my .gitignore, I excluded the TouchGFX/generated folder so that all files can be generated fresh when the project is built on a new system.I would like to be able to build the project in a Linux environment. However, since TouchGFX designer is not supported on Linux, I was hoping that I could run a make command to generate them without the Designer application. The only thing I could find was a command to invoke the tgfx.exe file provided with the designer.Is it possible to build the generated code from TouchGFX designer in a Linux environment?**EDIT**I have created a Docker container that is running Linux, I have installed WineHQ in it to run the tgfx.exe file. Unfortunately, the container is having issue with running the GUI, is there a way to execute the tgfx.exe functions without invoking a GUI/window?

Hi,which widget should I use to create a curved line?If there is no widget,what is the procedure to create a curved line?Thank you

I am looking for some advices for my product using STM32U5G9 MCU with external QSPI Flash.I want to create a bootloader for my product but I stuck at the approach how-to:1. Can the boot loader support the external loader meaning also update the external flash data if there is any updates for my GUI information?2. If the boot loader can't support the loading for the external flash, do I need to implement the external loader on the application layer?Is there any application note for case#1 if it is possible?Thank you so much for your advices.

Split from stm32f469I-Disco - TouchGFX Display stays black.Hey @Mohammad MORADI ESFAHANIASL , I have the same issue as the one above, but my TouchGFX does not have the version of stm32f469 disco with the au1 screen in it.I have 4.24.0 like your example.How can I fix this?

Hello,I am in the process of creating a modifying a TouchGFX project using the example project for the STM32H735G-DK kit.  I generated a project in TouchGFX and then modified it to use a larger custom 7" Display/touchscreen.  So far I have been able to get the display to show static images perfectly and I've even been able to modify the generated program to use a GT911 touch controller library for touch control instead of the default FT5336 controller.  All the works perfectly.  Static images look good and touches are registers and transitions from one screen to the next work.  The problem I'm having now is that during the transition the images seem to tare/glitch and I'm not sure what is causing this.  I've modified all the timings to match that of the new display, I've changed the LTDC clock to match that of the new display.  I've changed all the framebuffer settings to match the larger display.  Are there other timing settings I need

I have a scrollabe list where each item is a scrollable container.I'm handling the scrollable container with this logic https://community.st.com/t5/stm32-mcus-touchgfx-and-gui/doscroll-doesn-t-scroll-the-full-text/m-p/813190#M43805 (during handleTickEvent I manually change position of the text via code). Each scrollable container has the Horizontal scroll disable with enableHorizontalScroll(false);Now, I'm facing this issue https://community.st.com/t5/stm32-mcus-touchgfx-and-gui/event-dispatching-bubbling-and-event-interception/m-p/659244#M36957 where when I want to slide the list, I have to click the tiny portion between two items.

Hello,I am using the TouchGFX designer to create project and source files , afterward import the project to CubeIDE.I am using TouchGFX 4.23.2 and CubeIDE 14.1 .I've seen many question regards this topic , but surprisingly none of the advices solves this very basic problem for me.After creating the sources in TouchGFX, I am opening the CubeIDE workspace in the project root (not inside CubeIDE folder.From that location I've tried the following:1. File -> Open Project From File SYstem -> Directory:    Show two projects. One of the called as the TouchGFX project and the othe called CubeIDE.    None of them is exports nothing to the CubeIDE.2. Import Project -> Existing Project Into Workspace:    Import a project that *always* called CubeIDE, although in .project file there is another name.     In addition the .ioc file has another name.   

Dear Gfx Team,I worked on a project using CubeIDE 1.17.0 and GfxDesigner 4.24.1.I installed  and un-installed 4.25.0.Now, when I open \TouchGFX\mcu_project.touchgfx with 4.24.1 and press F4/F5, the version in \mcu_project.ioc is changed from 4.24.1 to 4.25.0.Why is that and how to stop it please ? Thank you  

So, I'm trying to have a text that scroll automatically if the container width is too small.My costume container will set the text and then calculate the width withtextLightSoundSettings.setTypedText(TypedText(T_AVVSONORITEXT)); if (textLightSoundSettings.getTextWidth() > scrollTextLightSoundSettings.getWidth()) { scrollText = true; pixelToScroll = textLightSoundSettings.getTextWidth() - scrollTextLightSoundSettings.getWidth(); }Then, in the container's tick handle eventvoid lightSoundItem::handleTickEvent() { lightSoundItemBase::handleTickEvent(); if(scrollText) { static int16_t pixelScrolled = 0; static bool scrollRight = true; if (scrollRight) { if (pixelScrolled < pixelToScroll) { scrollTextLightSoundSettings.doScroll(1, 0); pixelScrolled += 1; } else { scrollRight = false; } } else { if (pixelScrolled > 0) { scrollTextLightS
