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 ...

The project in youtube https://www.youtube.com/watch?v=suMytEyQTP4&t=616sis not working in cube IDE. I tried it using cubeIDE v1.10.1, GFX v4.20.0, cubeMX v6.6.1. The code compiles no errors. But the TFT shield is blank ! Can you help resolve this us...
I was double checking SPI speeds and functionality and noticed SPI pins switching state when they shouldn't be. I narrowed it down and discovered this only happens when the memory swap for the FMC LCD is enabled. There are some other posts from me ...

Hi,I am trying to implement simple GUI with TouchGFX 4.20 on STM32F303 MCU. I have limited amount of memory for GUI. Even few kBytes important. When I look memory consumption of TouchGFX I see weird functions that I don't call or not to use some widg...
This happens at randomly. Spent more than a month trying to figure out the issue and never suspected DWT. When I commented out DWT everything works fine now. Can someone educate me on why this is happening and how to avoid it? Thank you for your time...
Hi,I have integrated with lwIP and freeRTOS a VNC server on a STM32H757-EVAL.A VNC client works fine and I can see on it the first frame buffer drawn by the application; according to the VNC standard, the server should send a "new tile" (a square of ...
I am trying to use the STM32H723 as a video output (tying the LTDC pins to an ADV7115 to convert them to HDMI). The idea is to read the bus traffic of an old 8-bit computer and generate the display from that traffic (as part of other duties). My conc...
Hi there,as stated in the subject, it looks like the "Table_" fonts files are not updated when the ellispsis charaters are changed in the designer typographies tab. As a result the structures "static touchgfx::GeneratedFont" are not inited with the p...
I'm no MVP expert, so would like to get the opinion of those who are.I have a slider on a screen that controls the displayed value of a parameter in a TextArea widget above the slider. The slider position is converted to a floating point value and a...
