STM32 MCUs TouchGFX and GUI

Hi, maybe now reported, but seems no solution. My design uses U599 with GPU2D. Many images is svg ok. But for example toggle buttons is generated as pngs.For save flash space i preffer L8 as default image format, but here TGFX fail in render animation . For example cover south change screen with this buttons show failing renders. Require change images to ARGB8888 result to fine animations, but 4x more storege. In 2025 absurd situation.Next question is how manage change colours in presets in designer. For example same toggle buttons variants ...

Hello every,I created some text areas to display the file name, which comes from a character array provided by the user's input.  Below are the configuration settings for each text area.1.text area2.Texts->Typographies 

Hello All,I am new to touchgfx and looking to implement something where a array of structure containing name and other parameters to display. I need to display parameters on selection of the names displayed. I have a   created a container and able to update the parameter names to the textarea of scrollist as in picture.Now i need to implement a way where user can select any one Preset name and those corresponding parameters should load to the respective area. as in image attached. Just let me know the way to do it will try out things as suggested.

Hi Community,I’m working on an STM32H747I-DISCO board and trying to build a simple application using TouchGFX.I created an analog clock widget in TouchGFX Designer and successfully flashed it to the board. The clock displayed correctly on the LCD.However, when I modify the project (for example, changing UI elements or logic) and reflash it, the display does not update to reflect my changes.I am trying to develop application on analog clock which reads time through internal RTC and update in clock and it is failing.I’m looking for guidance on:Understanding how dual-core microcontrollers (like the STM32H747I with Cortex-M7 and Cortex-M4) handle TouchGFX applications.The correct procedure to flash TouchGFX-based projects after modifications, so that updates are reflected on the display.Any tips, explanations, or step-by-st

I am learning touchgfx with stm32f469i-disco board, how to configure dsi-video mode ? i want to use ltdc , dma2d, dsi-video.c  i download the demo  Edit: moved to a new thread from STM32 dev kit with DSI and demo software playing video from SD card (ideally using DMA).

Hello everyone,  I am using a STM32H750xx custom board with TouchGFX 4.24.1 and IAR version 9.40.2. I have an external flash memory using QSPI with memory mapped mode. I am encountering an issue after a firmware update is done. Here it is what I have done:  1) My firmware version 1.0.0 has an icf file with read only data located at 0x90000000-0x900FFFFF and Image,text and font located at 0x90100000-0x903FFFFF (as TouchGFX 's documentation says, I am using those keywords section ExtFlashSection, section TextFlashSection , section FontFlashSection in order to put image, text and fonts in external flash memory). It looks like this:   place in ROM_TGFX_region { readonly };place in QSPI_TGFX_region { first section ExtFlashSection, section TextFlashSection, section FontFlashSection };   where ROM_TGFX_region is from 0x90000000 - to 0x900FFFFF;

Look at this beauty. In touchgfx\framework\include\touchgfx\hal\Types.hpp:static const float PI = 3.14159265358979323846f; ///< PIIn CMSIS-DSP\Include\dsp\fast_math_functions.h#ifndef PI #define PI 3.14159265358979f #endifFortunately, the conflict is caught at compile time.It’s an exceptionally rare situation when you might need something from TouchGFX (e.g., instrumentation) and CMSIS-DSP at the same time — but when it happens, you get this delightful collision.Just in case anyone is compiling a list of tricky interview questions.

i build a LCD display board with stm32L431 and 320*240 LCD  and use touchGFX to develop UI, now i need control and select icon of LCD from external GPIO of STM32L431 , so, how to configure the touchGFX and concerned file ? anybody have similar program to refer ? 

I am attempting to use the X-CUBE-DISPLAY module generated from STM32CubeMX for a ST7789V display. The configuration requires the selection of the LCD BUS IO driver to be a SPI port in Full-Duplex Master mode. However my display only has a single SDA line for input and output, so the SPI has to be configured in Half-Duplex Master mode. X-CUBE-DISPLAY will not allow this SPI port to be selected, so the code generation fails.Is there a way for the X-CUBE-DISPLAY to work with a half-duplex SPI peripheral? 

Hello. I have installed Touchgfx to Windows. Am I right that I am generating code with Touchgfx and them import that code to my project on my Mac to CubeIDE ? Or the final upload step is on Windows in the Designer ? Thank you Edit: Moved from old thread I am using cube ide on my Mac OS . how I can use touchgfx with cube ide on Mac OS

Hello, I am blocked with a personnal project using a STM32F769I-DISCO, TouchGFX and audio: DMA IT is not triggered. I have no idea why, no idea how to investigate more in the code. I will provide few things in my question, not because I don't want but because I don't know yet what to provide. I created a project with TouchGFX Designer and now I want to add the BSP code to play audio. My code initialize all devices (created by the tool) and try to play audio /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_DSIHOST_DSI_Init(); MX_LTDC_Init(); MX_FMC_Init(); MX_QUADSPI_Init(); MX_DMA2D_Init(); MX_I2C4_Init(); MX_LIBJPEG_Init(); MX_CRC_Init(); MX_USART1_UART_Init(); MX_DFSDM1_Init(); MX_SAI1_Init(); MX_I2S1_Init(); MX_TouchGFX_Init(); /* Call PreOsInit function */ MX_TouchGFX_PreOSInit(); /* USER CODE BEGIN 2 */ /* Init audio */ initAudio(); playAudio(); while(1);

Hi,        If the project is large, multiple people need to divide the work to edit the UI pages, and then merge the edited pages together for compilation and debugging.       Does the software have corresponding functions that can enable team collaboration?        Best regardsJabari.Zhang

Hi I am developing a product based STM32 Microcontrollers. To start with the I am using a Development BoardNucleo H7A3AI Board.What I plan to do is, attach a LCD TFT Display to this and develop the prototype. I plan to use TouchGFX designer to develop a UI and develop the firmwareOne Problem I face to start with TouchGFX Designer is the development board  Nucleo H7A3AI  is NOT listed in the supported boards.  (I am using TouchGFX Designer 4.25.1 )The boards which are listed in TouchGFX Designer all have an attached display. In my case we are developing product based on Nucleo H7A3AI Board (This board does not come with a LCD Display).In such case how can I add my board (Nucleo H7A3AI Board) into TouchGFX Designer ?The display I am planning to use is From RockTech Model number (RK043HN10E-T)The pin connectionsbetween the display and Nucleo H7A3AI Board is shown below. 

Hi, My MCU is a STM32H753BIT6. This is a custom board that works fine with SYNC-MODE displays types.I have a new display only works in DE MODE. It not requires the HSYNC or VSYNC signals.Is there any way to configure LTDC peripheral and TouchGFX to work only in DE MODE? This is a communication image about this mode. I disconnect physically the VSYNC/HSYNC signals and ground it to make sure.Thanks for any tip and help!

HiThe normal behavior of the division lines and labels of the graphs are that the they are placed at the integer multiples of the interval set for the widget. If the offset on the axis are zero, it will off cause be the most obvious solution.But in our application we got up to three curves in the same chart solved by placing multiple graphs on top of each other as the have different units on the axis. Only one of the Y-axis starts at zero and the divisions are therefore defined by this.But as the two other graphs has offset not in the division interval, the labels are not placed at the division lines. They are placed in an integer multiple of the interval. And that does not look good. Of cause I could disable the labels created from the graphs, and place them manually using text areas. But is there a solution to offset the location of the labels (and there values) and the division lines?Examples. This is what is possible: (Of cause I can use t

I have a dynamic graph set to scrolling. When I call graph.clear(); it will set the initial graph back to my range 0-100, but once it starts scrolling it instantly jumps to the last highest value being the start of the new range instead of continuing scrolling.EX: Graphing is as expected to x = 200. Clear. Normal graphing 0-100. Once scroll starts, jumps to range 200-300 and starts graphing at x = 3000-200 : clear : 0-100 : 200-300 (graph and scrolling starting at 300)

HelloI'm an amateur Touchgfx user.I've completed many challenging tasks with Touchgfx, but I need a very simple one.I want to set the output port high for the duration of a keystroke.I used the ClickListener instructions in the program, but they didn't work.I tried creating Box1 the same way and it works perfectly.With this code, it works while I hold the button down, and stops when I release it, just as I wanted.void BRHZLView::boxClickHandler( const Box& b, const ClickEvent& evt){if (evt.getType() == ClickEvent::PRESSED) {HAL_GPIO_WritePin(GPIOG, BZR_Pin, GPIO_PIN_SET);HAL_GPIO_WritePin(GPIOB, PST_I_Pin, GPIO_PIN_SET);} else if(evt.getType() == ClickEvent::RELEASED){HAL_GPIO_WritePin(GPIOG, BZR_Pin, GPIO_PIN_RESET);HAL_GPIO_WritePin(GPIOB, PST_I_Pin, GPIO_PIN_RESET);}But the flexbutton group keeps giving definition errors, and the program won't compile.I'm using St

Dear I'am protoyping a GUI on a STM32F469I-Disco board and encounter the "feature" that buttons in the lower area of the canvas will not trigger when touched (e.g. the red circled "Auto"). Strangely when moving these buttons (e.g. "00.000V") to the upper area without changing anything else the suddenly work????Of course my first suspect was the FT6xxx touch controller chip, so I debugged into the STM32TouchController::sampleTouch(int32_t& x, int32_t& y) function. I confirmed that the touch controller worked as designed delivering proper coordinates on every touch (origin in the upper right corner, x increasing down, y increasing to the left) As of now I've no clue where to look, help appreciated!Thx MTP.S.: The canvas has been configured in landscape orientation in TouchGFX designer 

Hello, I am working with TouchGFX Designer version 4.25.0 and STM32Cube IDE 1.13.2 .Since today my build process does not work anymore and I get errors that some of the .hpp files are not existent. error notificationsI did double check the "missing" files but they are existent. Has anybody already had this problem and maybe can suggest a solution? Thank you very much.

Hello All, I have created one project which is working on STM32H747i- Eval board with 800 x 480 resolution, now the project has to be migrated to 1024 x 600 resolution for larger display.I have migrated the backend code but now the Screen resolution is still 800 x 480 and the widgets are aligned to work with it.Now how shall I configure the project to 1024 x 600, I mean is there any to do it instead of manually adjusting the screens and widgets ?If there is any effective and better solution kindly do let me know ? Regards,Shiv

i'm successful to drive RGB LCD 480*272 with stm32cube IDE , but if i change to touchGFX and load into target , it have some following error , remark: simulator is OK    

I just updated my TouchGFX version to 4.25.0 and try a simple two screens sliding transition with my STM32U5G9J-DK2 with ThreadX RTOS, and I found my sliding transition not working.  No more sliding, the screens just updated with a glitch.Can anyone please help to point to me where should I look into?  Is it relate to timing in the TouchGFX thread timing?Thank you for your helps.

I am trying to update a textArea object from a .c file.I have been able to open the screen by creating a wrapper, the wrapper also handles the data to update.  The screen is called ResultsView.cpp and the textArea is called textAreaTap to open the screen i created a wrapper: showResultsScreen()// ResultsScreenWrapper.cpp #include "ResultsScreenWrapper.h" #include <gui/common/FrontendApplication.hpp> #include <gui/results_screen/ResultsView.hpp> #include <touchgfx/Application.hpp> #include <gui/results_screen/ResultsPresenter.hpp> extern "C" void showResultsScreen() { static_cast<FrontendApplication*>(touchgfx::Application::getInstance())->gotoResultsScreenNoTransition(); } extern "C" void update_results_screen(const char* resultText) { auto* app = static_cast<FrontendApplication*>(touchgfx::Application::getInstance()); ResultsPresenter* pres
