STM32 MCUs TouchGFX and GUI

I'm using an STM32H7S78-DK with TouchGFX and FreeRTOS. I would like to limit the framerate of the target to 30fps but withouth reducing the LTDC frequency.Basically having the VSYNC fired at 30fpsI've already set the  ((touchgfx::HALSDL2*)&hal)->setVsyncInterval(33.333);In the simulatorIs there a way to force it on the target?

Hello,I've tried to reinterpret a char16_t string (specifically u"Hello")to UnicodeChar* usingreinterpret_cast<const Unicode::UnicodeChar*>they are the same ?What is the difference between them ?

Hi I am trying to gain knowledge on TouchGFX and GUI, with STM32 controller. can you provide me with the document or example from where i can start my learning to use TOUCHGFX and use multiple screen. 

Hello everyone,I am working on a custom bootloader for an STM32H743-based TouchGFX project and facing a very strange issue specifically with the TouchGFX application after jumping from bootloader.STM32H743 Bootloader Successfully Jumps to Simple App but TouchGFX Application Shows Black Screen After Bootloader Jump.I would appreciate any guidance from people who have experience with STM32H7 + TouchGFX + bootloader integration.Hardware / Project DetailsMCU:STM32H743IIT6Frameworks:STM32CubeIDETouchGFXFreeRTOSPeripherals Used in TouchGFX App:FMC SDRAMLTDCDMA2D

Hi STM Forum,I'm integrating a custom QSPI display controller with TouchGFX and ThreadX. I need to convert the TouchGFX framebuffer into RGB666 (6 bits per color) for a custom display interface that runs over SPI/QSPI.Here is my IOC. As you can see, I currently have only the QSPI and the clock connected.

Hi,I’m working on an STM based UI with multiple dynamic graph widgets on a single screen and running into a hard fault when scaling things up. Right now I have 5 graph widgets, each needing to plot around 700 data points dynamically. However, when I configure all 5 graphs with 700 points each, the screen crashes. The most stable setup I’ve managed so far is about 200 points per graph, anything beyond that consistently leads to a hard fault (which seems memory related).My goal is to reliably support 5 graphs × 700 points on the same screen. I’m trying to understand what could be causing the crash, whether it’s heap or stack limitations, frame buffer constraints, or something else in the graphics pipeline. It would be helpful to know how to narrow this down effectively.

Hi all, i search properties for manage showed multinumber counters without not cool moving.For example num 123 121 111 . Align not help here .My idea is mark textarea as number aligned and render calculate widths from font for 0-9 and use it to convert showing as monospaced . Ofcourse font editor can change this , but better is switchable choice. Exist or is this doable in an TGFX version?

Hi Community, I am using STM32H745I-DISCO board and generated a TouchGFX project and attempted to flash/debug from CubeIDE. The flashing process fails during the erase stage. Observed Errors Initially: “Error: failed to erase memory” After enabling external loader (without initialization): Erase still fails After enabling external loader with Initialize = true: “Failed to initialize external memory” “Error in initializing ST-LINK device” In CubeProgrammer: External flash is detected when selecting loader MT25TL01_STM32H745I-DISCO

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 d

In TouchGFX 4.26.0 image order changes in application.config even if those images don't change.This causes unnecessary changes to show up in git: Feature request is to either preserve the order or to have them always lexicographically sorted.

I want to design according to the Figma design, but I have no clue.How can I make the menu follow the selection in the simulator? If I want the last menu to scroll down.

Hi Team,Is there any framework or lib support available from ST for automation testing of TouchGFX based UI either on simulator or on actual device?If anyone has any idea or workaround, then please share!Thanks

Hi, I made a custom board and made a design in touchgfx. But my screen keeps being black.I want to confirm something because I think I made a mistake in my design. I selected the following display:MDT0130CIS-MULTI:https://www.farnell.com/datasheets/4321575.pdf?_gl=1*vshmrc*_gcl_aw*R0NMLjE3NzUxMjEwOTIuRUFJYUlRb2JDaE1JM1BxQnEtbk9rd01WdHprR0FCMXQ5Z2k1RUFRWUFTQUJFZ0xmZVBEX0J3RQ..*_gcl_au*MTM4MTIxMjM2Mi4xNzc2NDEzMzk5 Now in the datasheet from the ST7789V driver which is on board of the MDT0130CIS-MULTI display it says the following.

Hi everyone,I have a screen project displaying a camera image using an STM32N6. I've validated and run several peripherals like DCMIPP and DMA2D. I'm currently displaying a 720x576 resolution image from DCMIPP on the screen via layer 2 using bitmap addressing.My question is: Since I'm using internal RAM, Touchgfx uses one layer, and one layer is used for the camera. Because I'm not processing any bitmaps and need space, I've significantly reduced the size of the cmd_list area. After adding all this, I have about 300kB of free RAM left.Now, what I need is to be able to see this camera image in full size on my 1024x600 px screen. However, I want to know if this enlargement is possible and if it requires a cmd_list, i.e., vector graphics.Will I use vector graphics for this? Will GPU2D use the RAM allocated for layer 2 for this operation, or will it require an additional amount of RAM equal to the screen size? Best Regards,Onur

I have created a project with a scroll wheel of 10 items, each item is displaying a single digit 0-9. Imagine an odometer for instance.  I am incrementing a variable(num) every second and usingscrollWheel.animateToItem(num, 20);to scroll through the list of items, it is working as expected until it gets to 9. Instead of it the scroll wheel continuing to rotate the same direction to 0 it reverses the direction of rotation and scroll past all other digits to get back to zero.  I have verified I have the scroll wheel set as "Circular" and it does indeed display the scroll wheel correctly as if it was circular.  Can I somehow change this behavior?

Good day, ST community,I am writing to inquire about the possibility of updating the custom container used on each screen when a new change is made to the custom container template. Currently, I am required to delete the old custom container widget on all my screens and add the new updated container manually each time. Thank you in advance for your assistance.

After updating from TouchGFX 4.24.x to 4.26.0, the code generated cannot be compiled w/o manual correction - there are commas missing: const touchgfx::AbstractShape::ShapePoint<float> downArrowDisplayPoints[4] = { { 0.0f, 0.0f }, { 80.0f, 0.0f }, { 40.0f, 10.0f }{ 40.0f, 10.0f } };downArrowDisplay.setShape(downArrowDisplayPoints);downArrowDisplay.setVisible(false);add(downArrowDisplay); upArrowDisplay.setPosition(80, 61, 80, 10);upArrowDisplay.setOrigin(0.0f, 0.0f);upArrowDisplay.setScale(1.0f, 1.0f);upArrowDisplay.setAngle(0.0f);upArrowDisplayPainter.setColor(touchgfx::Color::getColorFromRGB(217, 141, 0));upArrowDisplay.setPainter(upArrowDispla

I am working with STM32F746G-DISCO development board for my phasor measurement unit project. The project displays few line parameter and a phasor diagram with a GUI and also sends data to a network.The project was first created with TouchGFX with all the GUI created and working standalone but when LwIP and ETH is enabled using the CubeMX the display does not work. The display has artifacts and also the other parts of the programme does not work.Please help me out to know what is the proper way of creating a project which uses TouchGFX for GUI and LwIP.  I am pretty sure that it is a memory conflict. Both LwIP and TouchGFX using the same memory region. But even after doing some MPU configuration and changing the framebuffer start address, the problem exists.I have attached the .map file of the project as .txt file for the better understanding.

Hi,When using this, single-character text isn't perfectly centered on the button,the letter appears slightly higher.Also, characters like .,_ appear higher than they should.Is it possible to adjust the text position horizontally when using these? 

Hi all, Thank you for looking at my thread.I have started a proof of concept project that runs ThreadX and TouchGFX on a custom QSPI display on STM32F7. I noticed from the documentation at https://support.touchgfx.com/docs/development/touchgfx-hal-development/scenarios/scenarios-configure-rtos that the following warning is highlighted.Now indeed when I generate the code from CubeMX the MX_TouchGFX_Init is n

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

Hi everyone,I'm experiencing a very specific bus/clock issue on a custom board using the STM32U5G9ZJ (and also tested on STM32U5F9ZJ).The Problem: My display (320x240, RGB565 via LTDC) only works if the HSPI1 peripheral is enabled in CubeMX. As soon as I disable HSPI1 (which I need to do to free the PH9 pin for power management reasons), the screen turns grey, even though the LTDC settings remain unchanged.Key Technical Details:Data Location: All assets (images/fonts) are stored in Internal Flash memory. The HSPI/OctoSPI bus is NOT used during the display process.Memory Status: In Debug mode, I can confirm via the Memory Browser that the Frame Buffer (located at 0x20025800) is correctly populated with pixel data.LTDC Behavio

I created the project in TouchGFX 4.26.0 Designer, modified pins with CubeMX_17, and attempted to debug the project in STM32CubeIDE 2.1.1. The example I used was Flex Button Example.Kit is STM32U5G9J-DK2.When I attempt to set up a debug configuration in CubeIDE, I am unable to select a project. This project compiles and works when I flash it to my kit through TouchGFX. Could there something wrong with my project structure? Thank you. 

For our product we use sliders to set parameters in our software. Some parameters effect the range of others at runtime. Sometimes the allowable range of the values is limited to a single value. In such a case min equals max. This leads to an assert error in the simulator and undocumented behavior on the target.We would like to see support for min=max. One way to implement it is to show the Indicator Image in the center (or left),  disable sliding, and set the value=min=max. This would simplify our firmware since we wouldn't need to handle it as a special case.I also added the tag bug-report since undefined behavior on the target is unacceptable.
