STM32 MCUs TouchGFX and GUI

Hello. I follow your instruction to generate a touchGFX project.  „How to TouchGFX: Creating my first GUI with TouchGFX Designer for STM GUI aplications“I‘m using the latest version of all Program for the STM32Cube family. The project compile in TouchGFX with no error. It so possible to download it to the board. All work fine. But after import to CubeIDE there is no xxx.ioc file include. I‘m not able to change hardware setting to onboard LED turn on and off.  

I try implement 1424x280 DSI panel and it work, but transition on single buffer have trouble.I start with simple fadeout and attached video show result. Try off DCACHE ICACHE DMA2D GPU2D, no big difference. Exist example or recomm for video mode with TE signal memory single buffer manage ? @GaetanGodart  ... seems i cant upload video  https://drive.google.com/file/d/1l9psb7h2DsEAAxUi8_kvEnL9ac-wNu1_/view?usp=sharingTGFX 4.23.2

I am looking into using an STM32 with TouchGFX to drive a 2.4" TFT LCD. The LCD will have some type of internal driver (ILI9340/ILI9341/ST7789, etc). Are there drivers for these already? Or is this relatively standard (I doubt)? Or do I have to write my own?Any good app notes/docs/tutorials that explain this properly?Thanks.

I use U599 driving a 480*480 lcd, there are two full screen texureMappers, two full screen cacheable containers. the first cacheable container rendered to dynamicBitmap1,the textureMapper1 use dynamicBitmap1 as source pic  . cacheable Container2 ( include textureMapper1 and cacheableContainer1) rendered to   dynamicBitmap2.textureMapper2 use dynamicBitmap2 as source pic and finally display on framebuffer.this additional textureMapper2 was to rotate whole content 180 degress.because the lcd is inverted.I have no other ideas.After I run the program , I got a 17ms rendering time.My question is: is that gpu2d's max ability?or I haven't set up properly?I use single buffer,with gpu2d and dma2d all on. 

Hello Guys,I am searching for a MCU to drive dual LCD screens. Although I see some MCU (eg, STM32U5G9ZJTXQ) providing both DSI and RGB mode interfaces without pinout collision, I didn't see any description about whether the LTDC can output 2 different images to the different interfaces respectively. Can I get your experiences sharing?Thanks in advance,SRONY

Hello,I'm developing graphics on an STM32H750-based board using TouchGFX, and my framebuffer is located in external SDRAM.I have a question regarding the MPU configuration for the external SDRAM that holds the framebuffer.If I configure the cache policy to Write-back, Write-allocate, would the following MPU settings be appropriate?MPU_InitStruct.TypeExtField = MPU_TEX_LEVEL1;MPU_InitStruct.IsShareable = MPU_ACCESS_SHAREABLE;MPU_InitStruct.IsCacheable = MPU_ACCESS_CACHEABLE;MPU_InitStruct.IsBufferable = MPU_ACCESS_BUFFERABLE; Additionally, is it acceptable to enable both MPU_ACCESS_SHAREABLE and MPU_ACCESS_CACHEABLE at the same time?I'm concerned that setting the SHAREABLE attribute might invalidate the CACHEABLE setting. Thanks for any guidance!

Hi,We have recently upgraded a project from TouchGFX v4.10 to v4.24, and have a question about colour representation. We haven't been able to update the HAL- this is a legacy project and we don't have access to the .ioc file.We've replaced the deprecated getColorFrom24BitRGB function, which returned 16-bit values, with getColorFromRGB, which returns a 24-bit color. We have worked around this by adding calls to LCD16bpp::getNativeColor in the various setColor functions, ie:  void setColor(colortype newColor) { color = LCD16bpp::getNativeColor(newColor); }  This works fine for the most part, boxes and most glyphs appear as the correct color (passed in to setColor as 24bpp, then converted to 16bpp using our workaround). But some glyphs are shifted to green/blue (white appears turquoise, light blue appears green), as though the conversion to 16bpp is getting repeated. This happens anywhere from 0 to 5 times within a text area, and all occurrences of a gi

I use the platform of STM32H747 to play a video with AVI format, if the frame width*height=568*320, touchGFX can't play this and skip this function,  which type of resolution can be used for touchGFX on STM32H747 platform ？ 

Hi all,Can anyone please give me advice how can I implement a custom Gauge:That will be used my custom image and needle That can be also a button, that when I click in the middle of the gauge, the gauge will change image to glowing as it is a button and turn off the gauge glowing as the button off for another click. Thank you so much.

whether can the touchGFX support to run PDF file or need changing to picture format ?

Hi,I’d like to use the vectorized version of a font (bebas-neue-regular.ttf), but the glyphs don’t quite match the original shape. Why is that, and how can I fix it?Could it have something to do with the arrow next to some nodes? I don’t know much about glyph design.The attached example compares the bitmap and vector versions of the font.Thanks for help.

Hello,I'm currently developing graphics on an STM32H750-based board using TouchGFX, and my framebuffer is located in external SDRAM.I've noticed flickering occurring in certain screen areas, especially when the UI becomes complex.After investigating, I discovered that configuring the MPU region for SDRAM as Non-cacheable completely resolves the flickering issue.I wonder what the recommended approach is in this scenario:Should I configure the SDRAM MPU region as Non-cacheable?Or, should I keep the SDRAM MPU region as Cacheable, and instead manually handle cache maintenance (e.g., using SCB_CleanDCache() at framebuffer flush or buffer switch points)?Which approach is the proper or recommended practice?Thanks for any guidance!

Hello All, I need to change the touch GFX project name MyApplication_747I to something else, I am trying to change it from config but touch gfx is not allowing it to change. I tried to edit and modify the  .touchgfx file and changed the name from "Name": "MyApplication_747I ",  to  "Name": "UI_Software", along with "ProjectFile": "../../STM32H747I-EVAL.ioc", to "ProjectFile": "../../IPL_UI_Software.ioc", Additionally I have changed file ApplicationTemplate.touchgfx.part  in this "Name": "IPL_UI_Software", and "ProjectFile": "../../IPL_UI_Software.ioc", While loading the file and opening the touchgfx project using the .touchgfx project I am getting attached Error. Could you please suggest what further modification i need to make or any corrections to do so that i can change the desire name of project safely. Attached are the logs for your reference to get better clarity. BR,Shiv

Hello All, I am new TouchGFX and working on it recently, I am trying to implement Long Press (if user touches button continuously) to increment value on Text Area, continuously until user releases flex button press.Right now, the configuration for flex button to trigger is for Click, I can see option for Touch as well but it's not working as intended.  I can see the value update every Click but need to have value to increase as long as User Touch is Pressed.Would appreciate, any guidance or some references to try out to do it. Br,Shiv

Hello So, I want to generate a test application, but I cannot load these on my board. Does that problem is normally because we never can upload a test application or what is the Problem here, I also added some parts to the Test application, but I can still not load up. I think I am a little bit stuck right now. Maybe one can help me. Thanks! ( I am useing the TouchGFX Designer 4.24.0)         

Hi Community,I have a project on STM32H755 Nucleo using a simple small LCD. Now I want to add a Riverdi display, RVT50AQFFWC00, which uses the FT813 EVE.I'm not very clear how best to start. From what I've found it seems that there's no driver for this display in the BSP for H755 and the best-looking driver that I've come across is Rudolph Riedel's (https://github.com/RudolphRiedel/FT800-FT813).Should I start by adding TouchGFX to my project via Middleware config in CubeIDE, drop Rudoph's driver into the project, then go to TouchGFX?  But then how to proceed, since I only see options in TouchGFX to use some pre-defined configurations that include H755 and similar displays, but there isn't one matching my exact configuration? If I use the simulator that's OK, but then how do I run on my target?Maybe I should instead start in TouchGFX and perhaps that allows me to pull the required driver in to my project and update my project with it?These probably seem like silly questions but any

hello,In my program I have some screens and I switch between screens by programaticily. If a button pressed below code switches screenvoid Screen1_View::changeScreenToScreen2(){ static_cast<FrontendApplication*>(Application::getInstance())->gotoScreen_Screen2CoverTransitionSouth(); }This code works fine but I want to change cover time too. Is it possible to change screen transition time ? Is it fixed ?

Hello,My TouchGFX application (without an operating system) receives events from a communication channel, and in some cases, there are icons on the screen that need to change visibility based on the received state. The events are acquired during the normal polling cycle of the application. When, for example, an alarm arrives, the icon with the exclamation mark is displayed in this way: void sHomeView::updateErrorView(bool error) { imgCommErr.setVisible(error); imgCommErr.invalidate(); } But invalidation does nothing; the screen portion is not redrawn.The invalidation is not lost; it remains latent until another successful redraw event is triggered — for example, if a button is tapped, the imgCommErr object is also redrawn, as are any other objects that are in the same abnormal state.To get it working as expected I need to call invalidation in this way: static bool needToInvalidate = false; static bool visibility = false; void sHomeView::onTick() { if (needToInvalidat

Hello!I have problem with initialization MIPI DSI interface on STM32H747. I use this interface for connect round LCD display with the St7797 display controller. But the problem is that when sending a sequence of LP commands to initialize the display, there is no data on the D0P and D0N lines. In this case, the signal is constantly present on the CLK lines. I am attaching a test project with settings. Tell me where the problem might be?UPDATE: If use LTDC controller, video data present on data line.But there is nothing on the data lines when sending init commands to display.I am attaching a test CubeIDE project with interface initialization.Regards, Alex

We developed a project based on this evaluation board and now we are in the final steps of making a product out of it.We need a similar TFT display to the one in the evaluation board (with similar Touch IC) but the problem is that we cannot find one.The display on the board is AM640480G5TNQW-T00H made by Ampire. Ampire do not provide any datasheet of this display. It is only 640X480 pixels.We are looking for a replacement which is pin compatible and software compatible with Ampire display but with higher resolution (800X600 or more). Size of about 5".We forwarded those specs to some TFT manufacturers along with AN4861 and most of them asked to see a datasheet of Ampire's display. We cannot provide one, it is not on the web and Ampire does not answers any E-mails sent to them - not for purchasing and not for information.Most of the manufacturers want to know which driver is used by the Ampire display. I wonder if anyone has the datasheet of this display or can tell me which driver IC is

Hi,in this touchGFX documentation page ( MIPI-DSI Video Mode | TouchGFX Documentation ) under the "DSIHOST / LTDC Initialization sequence" section it says:"The call to MX_DSIHOST_DSI_Init() must be done before MX_LTDC_Init(). This should be handled by STM32CubeMX. If this is not correct, take care to fix the order in a user code section." But this is the CubeMX generated code where it calls MX_LTDC_Init() before MX_DSIHOST_DSI_Init():   /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_LTDC_Init(); MX_RTC_Init(); MX_OCTOSPI1_Init(); MX_ADC1_Init(); MX_TIM1_Init(); MX_TIM8_Init(); MX_UART5_Init(); MX_ICACHE_Init(); MX_DSIHOST_DSI_Init(); MX_CRC_Init(); MX_I2C4_Init(); /* USER CODE BEGIN 2 */ /* USER CODE END 2 */  It looks like MX is generating it incorrectly... And swapping those lines every single time you change something in MX would be an insanely annoying thing to have to do (not to mention all sorts of other poten

Hello,I am currently using NUCLEO-G071RB with X-NUCLEO-GFX01M2, where I have implemented an animation that periodically updates a part of the display.When setting the animation interval to 100ms, I noticed that the main loop’s while execution time exceeds 100ms, causing delays in execution. To achieve smoother animation, I want to shorten the animation interval. 1. How can I reduce the delay in the main loop execution?2. Could the delay be due to the low clock speed of the MCU or the fact that the display uses SPI communication?3. If I switch to an MCU with a higher clock speed and use a MIPI DSI or RGB interface, how can I migrate my existing SPI display-based project to the new hardware?Any insights or guidance would be greatly appreciated.Thank you!
