STM32 MCUs TouchGFX and GUI

Hi,I have a custom board and im keen to get my design to be able to have buttons that trigger events when the user releases (onRelease) the button, as well as onPress.Is this possible and how would i go about achiving it ?Im using TouchGFX 4.20

Hello.I try to write a dynamic changed value in a text area.But it isn't possible to make a value output.I get allways "???" instead of my value.I used the video from ST: https://support.touchgfx.com/academy/how-to/textareaand try to change the text on runtime, but i get allways "????" as result. Even if i thy to write a unicode-string, a char string, a unicode-value...The only way to change the text at runtime is to use a static text and an additional wildcard text. counter++; Unicode::snprintf(Screen1View::textArea1Buffer, Screen1View::TEXTAREA_SIZE, "%d", counter); textArea1.invalidate();If i use only a Wildcard, all characters are a "?".If i use two text's ->  Auto-genera

I have succesfully built and programmed a TouchGFX application to my board in release mode. When I try to use the debugger I have limited success. If in the Project Explorer I highlight the (in FSBL) line and launch the debugger and press F8 my application runs. Any breakpoints I have set in my application do not trigger. If in Project Explorer if highlight the (in Appli) line and launch the debugger I receive an error "Failed to execute MI commad" It worked for me one time but I cannot relpicate the sequence that gave me that result. How do I launch the debugger so that breakpoints in my application will work?&n

X-Nucleo GFX01M1 not working properly with Nucleo-64, ARM Cortex M4, STM32 L476-Serie Hi, I Got My Hands Recently On a X-Nucleo GFX01M1 and I am now struggeling to get a Proper Connection > Everything I see Is White Screen. I have Simple Code For Testing the Screen :- Just Draw Everything Red On The Screen- Blinking LD2 on the Nucleo to see if the Code Is Running Or Not. So The Code Actuallys flashes correctly with 0 Errors and The LD2 is flashing but Still, only White Screen.https://drive.google.com/file/d/1r8Q8XvllzKyyLXUqnP15iG0EPqi2gGUq/view?usp=sharing

Hello,I download an example GUI from Touchgfx designer, generate code and run on my STM32H735G-DK board, it works well.Then I open the .ioc of this project and generated code with EWARM, open it and build, it has no errors.When I download it to board, the progress seems stuck and report error several minutes later. 

I had made a post about fixing OTM8009A video mode printing an extra frame on screen that I had solved with adjusting porch values even more for the horizontal, you can find the information within this post here:Video mode printing another frame on screen - STMicroelectronics CommunityFor this situation I don't think changing porch values are enough to solve this. I have the ST7701 LCD controller running TouchGFX in video mode on STM32F469I-DISCO, the testing screen in TouchGFX Designer is being printing twice vertically across the horizontal screen rather than printing across the screen horizontally, when I have the OTM8009A screen connected the image is printing in the correct direction and shows the testing screen from TouchGFX Designer, I don't have an image of the OTM8009A screen working correctly but in the post above

The SVGImage widget is a great tool but, as I understand it can only use SVG images from the SVGdatabase.I may imagine to subclass the SVGImage class and handle directly run time created lists of VGObject as it is done with the SVGdatabase.What is missing is to have the imageconverter tool code to run on the embedded platform. I mean the code that convert XML SVG text files to the VGShape , commands and points like those found in SVGDatabase.cpp.Could this code part be disclosed or a new function  like 'dynamicSVGCreate( )' be added to the lib.This function could return a VGObject being given a text string with the SVG content ?Or do someone have an other solution to dynamically decode SVG XML text to bitmap ?BRPierre

Moved from Feedback forum - the Feedback forum is not for product questions. Hello, I have a problem with using TouchGfx, if I create a project with an STM32F429 without adding any code the compilation is ok, if I activate TouchGFX (Graphic application checked) I have compilation errors (see attachment) I don't know how to do it, I would like to start with TouchGFX with this project Best regards Sébastien

I'm seeing "noise" in some objects drawn on the screen.  See pic... the yellow circle ("shape") should be solid yellow, but instead includes red-orange horizontal lines.  If the circles are rearranged the yellow circle can look correct, but the blue circle may have the lines instead - only lighter blue, not red-orange.  Also, the button can include some horizontal lines when showing the "pressed" version.  These lines can flicker a bit too.. possibly turning on and off very quickly.   What is causing this and what can be done to fix it?  There was some improvement when setting the Alpha to 255 (from 1

I have a STM32H73G-DK developement kit and I want to interface a custom 7" touchscreen/display with it using TouchGFX to create a basic menu structure.  I was able to get the display to show static images by following the guide in these youtube videos (from STMicro):https://youtu.be/yiHjOH7zJP0https://youtu.be/XnSg3UJfSFcFollowing these videos I was able to get a static image to display perfectly however I also need to get the touchscreen functionality to work as well.  The development kit comes with a smaller di

Hello,we previously used the STM32U5G9J-DK2 discovery kit with FreeRTOS and TouchGFX (with hardware-accelerated Vector Font Rendering, etc) successfully.Now we are trying to bring up a custom STM32U5G7VJ based board. We first created the ioc File with CubeMX, configured all the pins and later on enabled FreeRTOS and TouchGFX middlewares. As far as possible, the settings from the discovery board were replicated (except we now use RGB888 instead of RGB565 and a few different LTDC and OCTOSPI settings)After opening the project template in the TouchGFX editor, a hello world screen was added.However, when building in STM32CubeIDE, the following error occurs in TouchGFX/target/generated/HardwareMJPEGDecoder.cpp: fatal error: jpeg_utils.h: No such file or directoryWhen I compared the HardwareMJPEGDecoder.cpp file between the discovery kit project and our own, I noticed it's different: The one from the discovery kit is around 5

I am looking into making an Avatar widget (image inside a non rectangular container).I looked at some of the the lcd.blitcopy, canvas, circles and painters and getting a bit confused where you could apply a mask to an image to only render a section of it.I am sure this would be a great addition to the shared widget.Right now, I am looking into circles and their painters to figure out the paint() and drawn() operations.

   Although I have expanded an external flash storage for pictures and fonts.Due to the fact that touchgfx generates a large amount of code, the stm32h523cct6 flash is insufficient.   So can I use the address for 0xc000000 flash and address for 0x8000000 flash?I attempted to burn the program separately into these two flash areas. The burning was successful, but the program was not running normally. Do I need to modify or add other configurations? Or is this operation of mine illegal?

I want to control a servo motor with the PWM and I want to have a slider on the GUI to control the position of the servo motor, So I created a TouchGFX project added the slider and the intraction to a virtual function and I generated the code I opened the project in the STM32CubeIDE folder and I configured the pin and I created a header and a source file to develop all the necessary functions to control the servo moto (ie: Init, update of frequency...) When I go back to the TouchGFX Designer to upload the code, I this error that the file is not found  TouchGFX/gui/src/screen1_screen/Screen1View.cpp:4:10: fatal error: PWMSer.h: No such file or directory#include "PWMSer.h"^~~~~~~~~~compilation terminated.my question : how to properly add folders and source files to such project ? and if I am doing is the wrong way please show me the correct way to do it.

I have been using STM32N6 to conduct model training and deployment for the model zoo. Now, I want to transfer the generated code to my TouchGFX project for embedded use in the CubeIDE environment. However, when I am transferring several files, before the transfer, the original files did not have this error, but after the transfer, there is this error and it is particularly common, mostly for the official-generated code. As follows:  When these files are transferred：After the transplantation was completed, an error occurred：

Hello, I was wondering how can I change the values of each child within a container? For example, I have a container with 4 slider widgets. I want to be able to set the values of each slider using a for loop. Below shows a very simplified example of what I'm trying to achieve within Screen1View.cpp. I want to use array iteration instead of setting each slider value manually because I'll eventually have more than 10 sliders in the container. Screen1View::Screen1View() { } void Screen1View::setupScreen() { int presets[4] = { 5, 10, 15, 20 }; for (int i; i < 4; i++) { // in the container, each of the 4 slider widgets is being set to a preset value from an array containerSliders[i].setValue(presets[i]); } } While looking into this more, I saw that containers have a forEachChild public function, but I am unsure how to use GenericCallback for this use case. If this is

I noticed that any example created with touchGfx for the STM32H750B-DK demo board uses the ExtMem_Boot bootLoader that uses a 400Mhz clock instead of 480Mhz, but the strangest thing is that it uses a QSPI clock of only 50Mhz, when from the memory datasheet it could reach 120Mhz.

Hello everyone,I'm currently working on a project with a custom electronic board (still in development). This project includes a 1280x400 display, driven via MIPI DSI by a processor (likely an STM32F429ZG or STM32F479ZG depending on the required pin count). Additionally, I prefer not to use an OS (so no FreeRTOS).To test the display part, I have an STM32F769I-EVAL evaluation board. Initially, I would like to generate a project, display some content using TouchGFX, and interact with it via embedded software (e.g., updating circle progress). Once this is set up, I plan to connect my custom display to the board (we have an adapter board for this).I have tried creating projects via TouchGFX and then importing them into STM32CubeIDE (as indicated on the TouchGFX site on the "Running without an RTOS on a TouchGFX Board Setup" page and in other tutorials) but without success. I also tried creating the project via STM32CubeIDE, enabling TouchGFX in the "Software Packs,"

I started with the STM32F469I-DISCO which always places the screen in portrait mode (480x800).Is there a way to change that to landscape mode (800x480) at the start of the design process?It would be much simpler to design that way than to have to rotate it after the fact.Thanks

hiby this code click event enable for 2 Continer  and work fine    void CNTR_A_ClickHandler(const CNTR_AntenaLevel&, const touchgfx::ClickEvent& e); touchgfx::Callback<MainView, const CNTR_AntenaLevel&, const touchgfx::ClickEvent&> CNTR_A_ClickedCallback; CNTR_AntenaLevel1.setClickAction(CNTR_A_ClickedCallback); // ******************************* void CNTR_B_ClickHandler(const CNTR_TempLevel&, const touchgfx::ClickEvent& e); touchgfx::Callback<MainView, const CNTR_TempLevel&, const touchgfx::ClickEvent&> CNTR_B_ClickedCallback; CNTR_TempLevel1.setClickAction(CNTR_B_ClickedCallback);   but i have 14 Container   in this method i have to add many code line for each container for "Click Event". is it possible use one container Clicked Callback for multi type of container?&nbsp

It have a new project with LCD(4.3' RGB:480*272) and touch panel, To drive this LCD and touch panel, i will select STM32H750VBT6 to develop , Whether can the TouchGFX support this MCU or not ?

Hello everyone,I’m working on an STM32 project using TouchGFX and STM32CubeIDE. The code compiles fine on the real target, but when I try to build the TouchGFX Simulator, I get the following error repeatedly:fatal error: i2c_data.h: No such file or directory The i2c_data.h file is present in my project under Core/Inc.It seems the simulator build does not include the folder containing i2c_data.h in its include paths.Any guidance on:How to add additional include directories for the TouchGFX simulator? Thank you very much for your help!

Hi all,I'm looking to integrate our translations from TouchGFX designer into a localization program, but does anyone have an idea how to convert TouchGFXs xml format to XLIFF or other more general formats easily?

Hello,I am trying to import several images into my TouchGFX assets. I'm able to load them in and build, but when I flash my application hard faults. I've noticed the error once I exceed ~8Mb in the external flash.I believe I should have 64Mb of external flash. Is there a way to adjust the partitions? Has anyone else seen this problem? Thanks
