Discuss STM32 and TouchGFX implementations, including configuration, debugging, and optimization.
Hello community!On March 18, we launched a TouchGFX Contest that had for goal for us to see our community's skills and creativity. This contest ended on May 2.We received several interesting projects, and it is now time to announce the winners! Our h...
We wish to always improve our documentation. The best reviews and critics always come from the people that read it, so we would like to use this post to collect your thoughts and feedbacks. Please share what you like, dislike, what you think is missi...
When creating a UI project, you may need widgets that are not part of the TouchGFX library. To create your own graphical element, the TouchGFX team suggests using the Custom Container approach. Since TouchGFX 4.20 it is possible to export and import ...
Hi all,I'm building a custom board with touchgfx and QSPI resources.Everything work well!I would like to know how is possible to remove loader to fast the debugger session: the external resource need more than 4Mbytes and loader everytime I start a d...
I try to connect LCD by SPI to Nucleo-767 and TouchGFX. LCD screen work perfect and I could draw on it without a problem, but I stuck with TouchGFX. I found that void TouchGFXHAL::flushFrameBuffer never call.Check this video - https://youtu.be/1UhEx7...
Hello. We have a need to work with a 16-bit 8080 style LCD interface. Would like to have the benefits of the latest TouchGFX tool (4.16.0) and STM32CubeMX to build quickly and debug our GUI screens. After some investigation, found the following kit w...
Hello, on my STM32H747-DISC1, I had huge issues with DMA2D and CLUT (it was freezing etc).I thought it's because cache maintenance, but anyway after doing everything correctly, DMA is still buggy. Finally I find out, that 90% of my DMA2D executions t...
Hello, I have my project based on STM32H753I-EVAL with RGB LCD display and SDRAM.I'm using DMA2D to render lines with CLUT L8 (Pulling mode). Basically, I process data for one line (one line have 320 pixels), and then execute it 108 times (for height...
Hi All, I am working on TouchGFX using STMCubeIDE( STM32G474 Eval-Board). There is a need to implement external flash driver for the project. I am using QSPI for implementing the flash driver. In linker file I have memory definitions as below : /* M...
Hi,I have allocated memory in external sdram and set buffer using CanvasWidgetRenderer::setupBuffer() method. Generated base class for my view is allocating memory in internal RAM and in constructor is passing it to setupBuffer mehod. How to avoid th...
Hello,I am looking to perform a similar resource usage as explained here https://support.touchgfx.com/docs/basic-concepts/memory-usage/However, I am wondering if there is a guide that is available using freely available tools to dothe memory analysis...
I'm new to ST products and am trying to run the LCD_DSI_VideoMode_SingleBuffer example on the Eversion VGG128017-C TFT screen. I get the backlight to turn on, but never see anything. Does anyone know of any specific drivers for the VGG128017 family? ...
I'm using a texture mapper to rotate an arrow inside a circle. That works perfectly well as long as the arrow is included as image asset and this image is directly set as image in the texture mapper.As soon as I remove the arrow from the assets and p...
