STM32 MCUs TouchGFX and GUI

Hi,I am using an STM32N655X0H3Q interfaced with an NHD-7.0-800480EF-ASXN#-CTP display that uses the FT5426G capacitive touch controller. I have created a TouchGFX screen containing a single button widget. No interactions are currently assigned to the button (I had previously tested it with a screen-change interaction, but the behaviour remained the same, so I removed all interactions and am now testing with only the button widget present on the screen).The touch controller appears to work correctly otherwise. I can continuously poll touch events inside STM32TouchController::sampleTouch() and successfully print the touch coordinates and number of touch points when touching any area of the screen outside the button.However, as soon as I touch the button widget, the application hangs. The button disappears and the display turns into a plain screen. At the same time, the continuous polling inside STM32TouchController::sampleTouch() stops completely, indicating that TouchGFX is no longer ca

EnvironmentTouchGFX 4.26.1 (Engine + prebuilt library) LCD config: 8bpp, `LCD8bpp_ABGR2222`, 240x240 Reproduced on Windows simulator (MSVC), Linux simulator, and STM32U595 hardware. Same TouchGFX source across all three, so this is not platform-specific.SummaryWhen an ABGR2222 dynamic external bitmap is drawn with `LCD::drawPartialBitmap` and the source rect extends past the dirty (clip) rect on the Y axis, the clipping path writes the overhanging rows starting at the dirty rect's top (`dirtyRect.y`) instead of at the requested `screenY`. The result is a duplicated copy of those rows at the wrong vertical position.X-axis clipping is correct: `screenX` can be negative or off-screen with no issue. The defect is specific to vertical overhang. Trigger conditions (all must hold)Bitmap format `Bitmap::ABGR2222` (the other three 8bpp 2222 formats compile to identical code, so they are likely affected too) Bitmap registered with `Bitmap::dynamicBitmapCreateExternal` Drawn via `LCD::drawPartial

Hi all,I currently working on a project using TouchGFX, multiple tasks are using functions from <math.h> which are not re-entrant, so I have them mutex protected. The drivers using these functions are written in C.Does anyone know if the TouchGFX library uses any non re-entrant library functions? Do I need to be careful with anything I use in the application?Kind Regards,Anthony 

Hello wonderful ST Community!Before I get into the question, a bit of background on this project. I'm creating a button panel HID gaming device for the space sim Elite Dangerous. Using its somewhat limited API I'm hoping to feed info about the game state back to a 9 inch screen on the HID device through USB CDC running composite with HID. Before I start getting into hardware dev I want to create a sim of the GUI to test two things:- size of display needed to show what I want to show- getting data out of the game (will be done with a USB CDC app/driver/python (I have not quite got this far) running on the host computer)It would be amazing to test these two aspects using the GFX simulator. I known it's theoretically possible to send data through some medium such as sockets but how does this work in practice?Is there some good documentation around how the simulator works and how I can feed data into my sims?I've been investigating using VSCode since GFX already has compatibility, but how

Hello everyone,I am developing a UI using TouchGFX on a custom board based on the STM32F767. I am encountering visual artifacts during screen updates.As seen in the attached video:In the date selection wheel, the text overlaps, tears, and leaves ghosting artifacts during scrolling.The first menu ("Date & Time", "Language" etc.) is inside a ScrollableContainer with a ListLayout. Initially, the text is corrupted. However, as soon as I scroll this container, the artifacts disappear completely and the screen draws correctly.System Info:MCU: STM32F767GUI: TouchGFX (Version: [Sürüm] )Memory: Framebuffer is located in [SDRAM vb.]Configuration: MPU is ENABLED, D-Cache is ENABLED.What could be causing this issue? Any suggestions on which configurations or settings I should check?Thank you!

Hi,first time TouchGFX user but not new to graphics programming and hoping to get some help understanding a TouchGFX problem I'm having on a Riverdi RVT50HQSNWC01-B I'm thinking of using for an automotive dashboard display.If I don't throttle my display changes, the display buffers don't have the same content. The buffer with the most complete looking content does have a small glitch towards the bottom right hand side of the RPM segmented display, so I'm guessing it's not as simple as TouchGFX didn't get around to doing all updates on both buffers but more like it ran out of space somewhere to manage the updates? I've tried putting invalidate()'s either side of making changes, as suggested in this (https://community.st.com/t5/stm32-mcus-touchgfx-and-gui/double-buffer-one-buffer-is-not-updated/m-p/165271#M9822) thread, but that doesn't help. The only thing that helps is to throttle updates inside the screen handleTickEvent() to every other tick (and not do them the first 3 ticks either

I have 2 problem in my touchgfx project.I use STM32G4 series. I have an external loader with a starting address of 0xA0000000. I can perform read and write operations with this loader using CubeProgrammer. However, when I define the external loader via CubeIDE, it programs the address 0x080000000. Then I get Hard Fault.   Here is my flash.ld The external loader starts working when I start it with the external loader address 0x00000000, but I want to start with 0xA0000000. How can i fix it ?Also my second problem is texts. My text datas are sending to external flash, but it is not appear. Then I changed font section to internal flash in flash.ld, my text was appear. Here is my changed sections side.  The textures are changing because something else is changing. Why isn't the screen showing the text I added with the external loader?

Dear all,I am writing to request assistance with activating an Ethernet connection between my PC and an STM32N657-DK development kit using NetX Duo.While my TouchGFX design is currently functioning correctly on the board, I am encountering issues when attempting to enable communication. Specifically, after flashing the Ethernet configuration, I am unable to successfully ping between the devices. I have attempted several troubleshooting steps but have not yet been able to resolve the connectivity issue.Please provide guidance or instructions on the proper configuration steps to establish this connection. Thank you so much. 

This is a small feature request to fix an annoying quirk of the TouchGFX Designer.When opening the texts menu in the designer, all of the texts groups are expanded by default. In projects with many texts/groups, its tedious to collapse all of the groups or scroll to the bottom of the expanded groups. I think it would be better if either TGFX stored the state of the groups expansion OR collapsed them all by default.

I am currently using TouchGFX to develop a project. How can I independently control GPU2D to draw graphics on a dynamic bitmap without affecting the TouchGFX display? I have already obtained the NeoChromSDK, but the examples in the NeoChromSDK all use GPU2D independently as well.  I can draw with GPU2D if touchgfx not in use,But once I display them both, screen got glitched.

Hello ST Community,I am using STM32H7B3 + TouchGFX + 7-inch 800×480 TFT with GT911/GT9111 touch controller.In the TouchGFX PC simulator, all buttons and toggle switches work correctly. But after flashing to hardware:TFT display is working properly.Touch is detected.Actual touch point and detected touch point are different.Touch is detected on the same horizontal line, but the vertical coordinate is shifted/wrong.I want to know the correct solution for touch coordinate mapping/calibration. Should this correction be done. Please guide me on the correct method for touch calibration and hardware control/status display in TouchGFX.Thank you.

Hey,I have my images stored compressed (ARGB8888) on NAND flash accessed via FileX. Not memory mapped, so I need to cache everything before starting the GUI.I noticed this in the Bitmap API docs:Bitmap::decompress — "This method is called by Bitmap::cache when required."So does that mean I just implement BlockCopy with FileX, call Bitmap::cache(), and it handles the decompression automatically? Does it allocate for the uncompressed size and deal with the temp buffers internally?Would save me a lot of headache if that's the case;Thanks!

Hello everyone：On touchgfx support website:https://support.touchgfx.com/docs/development/scenarios/touchgfx-on-gpu2d ,there is a demo of map using NeoChromVG,this is the demo videoSo,where can I get this demo project?

I am trying to interface STM32U5G7VJT6 with MT25QL128A using OCTOSPI1 in Quad SPI mode, but I still cannot store/run TouchGFX assets from external flash memory. Current configuration: Memory Type: Micron Device Type: Flash Device Size: 24 Clock Prescaler: 2 Clock Mode: Low Sample Shifting: Half Cycle Wrap Size: Not Supported Delay Block: Bypassed Screenshot attached.Could someone please check if I missed any important configuration like memory-mapped mode, linker settings, TouchGFX asset location, BSP/init sequence, or MT25QL128A command setup?

Greetings.I'm a Linux user, I use Windows on a smaller notebook for tools like TouchGFX, but this is quite inconvenient.Is there any plan to release a Linux version of TouchGFX Designer?I saw in the documentation that there's a simulator and that it can even be used with Wine; I'll test it today, but it would be really good to have a native version.Link where I saw information about the simulator: https://support.touchgfx.com/docs/introduction/prerequisitesthanks

I have a TouchGFX (latest version) application using STM32H753 and an OLED with GRAM.  Runs under Threadx.I found the development process quite complex but had no problem eventually building the project with all the subsystems apparently working properly.BUT....The very simplest part of the task I cannot complete.  I want C code in a ThreadX Thread to initiate the redraw of the next frame in the single display buffer (after which the DMA would be initiated from the frame buffer to GRAM...).  I need to access the OSWrappers.hpp in order to provide "Vsync" to TouchGFX which I can't do from "C".  After days and days, I can assure you there is no apparent way to call the relevent C++ method from the C code within Threadx.  In other words there is no 'hook' on the "C" side to make the function call.  Any suggestions?None of the Google-search documentation on this subject makes any sense.Thank youGerry

Excuse me, how can I implement this kind of loadingI'm really at a loss for ideas. Please help me out, thank you

  Hello ST Community,I am working on STM32H7B3LIH6Q with TouchGFX.I have successfully initialized the TFT RGB display on hardware, and the RGB test output is working properly. I created two screens in TouchGFX Designer, where pressing a touch button on Screen 1 should open Screen 2.This works correctly in the PC simulator, but on actual hardware the touch command/button press is not working. The display is visible, but touch input is not detected.I have attached the hardware output image and my touch enable/source code for reference.Could anyone please suggest what I should check in the hardware touch interface? Is the issue likely related to , BSP touch driver, I2C touch controller initialization, or touch coordinate mapping?Thank you,Vijaya.  

What is the recommended procedure for adding source files (e.g. source1.c and source1.h) to a STM32CubeIDE project generated by TouchGFX? I assume I add them to one of the 'Core' directories, but I see multiple Core directories (root\STM32CubeIDE\CM7\Application\User\Core and root\CM7\Core). I see that adding my .h manually to root\CM7\Core\Inc works fine for the .h, but the IDE doesn't automatically pick up the .c if I place it in the corresponding root\CM7\Core\Src. If I place the .c in root\STM32CubeIDE\CM7\Application\User\Core, the .c file is accessible via the IDE, but the .h file is not found during compile.What is the proper procedure for adding new user C source files?  My STM32CubeIDE is 2.1.1 and TouchGFX is 4.26.1. I'm targeting a Riverdi board with a STM32H7. 

How is it with availability, are we updating what was once part of CubeMX? namely STemWin, i.e. the Segger enWIN version that was offered for free for the STM32 processor?I didn't find anything about ST, except that it's not part of newer versions of CubeMX.You can find STemWIN on Segger's website, but they're basically just trying to sell emWIN at a discount.Alternatively, where can I download the latest version of this library?Thank you for the information.

Hi !I've using TouchGFX Designer for a while, only using Simulator project (which Board setting is PC) for sfx evaluation and learning. And I wanna try to flash my previous project running on a real microcontroller board like F429 discovery board.Here's my question: How to migrate my previous PC Simulator project to new CubeMX project based on real board project?I tried to find related settings in TouchGFX but failed. Is it the only way to migrate my previous ui into new project by doing all the steps in the new TouchGFX project？Thanks !
