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 have a monochrome RGB display which expects on the green pins a 8 bits grey scale value, 0x00 is black and 0xFF is white . I managed to make it work without TouchGfx, configuring LTDC with L8 pixel format on layer 0 and using a LUT (HAL_LTDC_...
Hello,I have an STM32F777 with FreeRTOS and TouchGFX. An ST7789V2 display is controlled via SPI with a partial framebuffer. After a certain time the TouchGFX task gets stuck in the function “getBlockForTransfer(Rect& rect)” in the line “assert(state[...
Hello, i see trouble with I2C HAL_I2C_Master_Transmit(&hi2c2, addr==0 ? I2C_ADDR_DACR : addr, Buff,3,5);in project with TouchGFX RTOS i have two threads. One for GUI and second is this hw I2C.On scope i see, that I2C sometimes (random) split send or ...
Hello, I am a beginner developer who is new to STM32 with TouchGFX.I am currently trying to display the GUI configured in TouchGFX Designer on a custom board consisting of an STM32F429IGT6 MCU and IS42S16400J - 7TL SDRAM.I have completed all GPIO set...
Hello,I am using TouchGFX with freeRTOS on an STM32G0 board.I call the touchgfxSignalVSync through a Timer Interrupt and quickly after I get an HardFault in the blitCopyARGB8888 function. As this is a library I cannot debug further. I am trying to go...
Hello, it is possible to call a function to change screens in a "stm32h5xx_it.c" file?The goal here is redirect user to a different screen globally, with no need to do this in every screen individually. This function is called in "EXTI15_IRQHandler(v...
Hello, I need to use Touchgfx on a small CPU and I'm optimizing my code accordingly. However, in the code that Touchgfx Designer generates, I noticed something that I don't understand:The Screen classes inherit from the ScreenBase classes.The Screen ...
Hello I see on this link that Touch Gfx can only use a single layer from the LTDC.https://support.touchgfx.com/docs/development/touchgfx-hal-development/scenarios/scenarios-ltdc-parallel-rgb Is there some way of using the two LTDC's layers ?,May be i...
I build a LCD driver board with STM32H750ZBT6 ,then i want to use built-in LTDC driver and SDRAM to run 480*270*16 TFT LCD panel , but touchGFX list following wrong message, where reason from ? Generate CodeGenerateDoneGenerate Assetsmake -f ...
I am using TouchGFX to design GUI, and I want to use a dynamic bitmap to show an image captured by the camera. The camera is about 600*480 size. But I set the CacheAddress as following, and It turns out that the GUI cannot run properly. Is there any ...
