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 ...
Hello,I am using the STM32H7B3I-EVAL evaluation board with a code generated by TouchGFX 4.20.0. My goal is as follows:Using a button (in this case, the Wakeup button on the evaluation board), change a PWM's duty cycle in stages (0% -> 25% -> 50% -> 7...
Hello,I've found a bug during code generation using STM32CubeMX on STM32H725AE MCU.STM32CubeMX doesn't generete correct code for DMA2D using RGB565 format. In function:void MX_DMA2D_Init(void) { /* USER CODE BEGIN DMA2D_Init 0 */ /* USER CODE...
Hi,I am working on a TouchGFX project, which connects my STM32F429IIT6 with a custom board with 2.4" TFT display. The Display include a ST7789vi chip and uses the 16-bit (RGB-5-6-5) input. I have found the STM code for the st7789h2.How do I get the r...
Hello,I am running a TouchGFX compiled code and am attempting to display a value from my code onto the LCD screen. I used the Tutorial 2 format for using the Unicode:snprintf function, but I am getting an error."TEXTLED_STATUS_SIZE" was not declared ...
Hello,I'm implementing an application with touchgfx, i use wildcards with buffer, and two buttons that increse or decrease the value in the wildcard.When i go back to previous screen, and re enter the screen with wildcards, those resets to initial va...
Hi,I want to transfer DCMI data using DMA into SRAM and then process this with the CPU.I'm using the STM32H743.What will be faster:A:Using DMA1 or DMA2 to transfer data into SRAM1 or SRAM2 and access it with the CPU.B:Using DMA (MDMA?) to transfer da...
Hello, I have been following this tutorial to enable touch screen on my STM32F469-Discovery board for STemWin.I have done all the things shown in article. Code compiled successfully. But I can see only blank screen.In extra to the tutorial, I need to...
Hello,we try to display graphs as performant as possible. Unfortunately the rendering takes a long time. Especially when several are integrated in ScrollWheels.The CacheableContainer should be made for this.We put a graph and more widgets in the cont...
