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 ...
Hi, I has some questions about how to save data in QSPIFLASH.I notice that when touchGFX is running,the QSPI would be set into memory-mapped mode and status would be busy.User can not write data in memory-mapped mode. I had already assign address for...
In my first screen,it has 4 buttons compare the 4 Swipecontainer pages in next screen.Can I let next screen know which page should be set?
Basically, I'm hoping to try out a different Microphone on SAI_2 and it looks like those pins would be freed up by removing the LCD display.
Hello all,This is not a common question. It is just to report a "bug" I encountered, to get feedback from the forum about my solution and a warning to others that may face this same problem =)I suffered some strange "behaviors" when executing a simpl...
Hi,I finished the board bring up introduction: Board Bring Up Introduction | TouchGFX Documentation without any troubles. I can also write and read to the external flash through DMA2D by using the following function:LL_FillBuffer(LTDC_LAYER_1, (uint3...
Hi,I'm struggling with the BSP LCD functions. The goal is to display an image which has transparent background. I'm working on STM32F429I-Discovery board, using BSP LCD drivers.Since the BSP_LCD_DrawBitmap() function seems to expect a real BMP file, ...
I have a toggle button widget directly dragged from TouchGFX designer to the UI. I am unable to manually set the state of the toggle button to True/False using the ForceState (it just flashes between True/False every time I set the state ) Is there a...
Hello,In order to do some complex animation like screen slide transition, I would like to add a second framebuffer to my touchGFX project on the STM32F469I-DISCO board (800x480 screen). According to the documentation given by ST, I've got 16 MB of ex...
I use a scroll list with setItemSelectedCallback. In principle, it works. But our measurement device needs to be explosion proof and therefore it has a rather thick glass above the screen.If an entry of the scroll list is selected, it sometimes happe...
Also some sample code, just to start, may be useful for unserstanding events and how to connect events to the microcontroller state.
