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 ...
According to the documentation, widgets are only redrawn once in the 'render' phase:https://support.touchgfx.com/docs/basic-concepts/rendering#renderHowever, when I call `invalidate` on a widget from a function that is not the `tick`, it is immediate...
Hello, I am doing these steps: I made a new projectadded a button with a random image and a text labelcompiled and executed opened the project in stm32cubeide added into the project some libraries that I am using to read sensors compiled and executed...
Hi, The same size images, one uses format L8_RGB565 with background colour and the other uses format L8_ARGB88888 transparent background. Two images for screen transition and the L8_ARGB8888 is smoother than L8_RGB565. Screen2 used L8_ARGB8888 ...
Hi guys,I'm trying to make a Text Area work like a button by adding a ClickListener Mixin to it. I tried to follow this guide but for some reason, every time I click the label, it doesn't do anything (I added a print and it doesnt print).HPP#ifndef S...
When the button on the LCD is pressed, the relevant screen is displayed and data (6000 bytes) must be saved. When the button is pressed, the screen is displayed without any problem, but a DMA error occurred in the process of writing data to the memor...
I have a STM32F446VCT6 MCU running TouchGFX project communicating SPI to a LCD. The images are located in the external QSPI which is in memory mapped mode.Basically I have a few simple screens. Everything is running fine, except that after some rando...
Hi there,as stated in the subject, I can't get the Hebrew pointing/dotting rendered properly inside the strings. It seems that these characters (U+05B0 to U+05C4) are printed as standalone characters and some kind of kerning info is not considered by...
Hello,when i need to include cpp headers in main.c to use classes and cpp functions, I usually convert project to c++, rename main.c to main.cpp and everything works good.Now I started project with TouchGFX. The only way to compile project without an...
I want to use touchGFX on STM32L496G-Disco with a screen connected to spi1 and not the on board screen.the screen connected to spi1 is supported on another board with the driver in ST7789.c + .h when it is connected to STM32L476RG_NUCLEO. the problem...
I am trying to "press" a button without actually touching the touchscreen of my development board.Reading the TouchGFX documentation, I found that there is a method calledClickEvent, that seems like it might do the trick.I tried calling the following...
