Discuss STM32 and TouchGFX implementations, including configuration, debugging, and optimization.
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 ...
Title says it all really - just enabled hardware jpeg decode and I've lost my last mem2mem DMA channel. Various image manipulations (creating BMP file from camera image for example) requires moving a lot of data about for which up to now I've used me...
We are creating a display application using an STM32F7, using the LTDC and the DSI with the wrapper enabled. We program all DSI and LTDC registers, and perioidically write pixel data to the framebuffer and then refresh using (DSI->WCR |= DSI_WCR_LTD...
I've been trying, on and off, for years to get a STemWin application up and running using any of ST's "CubeMX" products to create the project from scratch. I've never had any luck. I've always thought that I've been doing something wrong, but I'm slo...
I have installed the last version of TouchGFX Designer.I choose the board STM32-F429ZI and an example.I may simulate the example in the computer and it work correctly. But, even though I have connected the board to computer, the button "Run Target" i...
Is there an example of how to specify and use the callback functions for the Scroll Wheel? And how can I get the currently selected item, if not via the callback. I found getSelectedItem() in the documentation, but it seems to be protected.
Hi, I'm new here and I'm starting to develop an application on STM32H750 with TouchGFX. I've read about the STM32 LTDC's L8 (8-bit luminance or CLUT) mode. This would give a palette of 256 colors which is more than enough, and use very little memory....
I am using the STM32F469I Disco board.I have created a project and then opened the generated Keil project. I simply try to build the generated project. The errors appear to be caused by not linking to the 'stm32f469xx.h' file. The correct compiler #d...
Hi,I have been leaning how to use TouchGFX with the STM32F429I Discovery Board. I have managed to get buttons to work with hardware and for it to call Virtual function to toggle GPIO pins. however when i have tried to add a virtual function with a sl...
Hi,I'm currently trying to display a JPEG image in STemWin, which is loaded into extRAM. Therefore, I can use the GUI_JPEG_Draw() method, which (as the documentation states), should ALWAYS return 0. While it does indeed display the image and return 0...
