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'm using a STM32H747-DISCO to sample a signal and would like to display the result on the TFT-display.I have written a program code that do the ADC-sample in CubeIDE and I'm only using the M7 core, the M4 Core is put in sleep mode.I started Touc...
HelloI am trying to encode an image of (160*120) in grayscale format - i.e a bmp file of 1bpp color depth.Unfortunately, the encoder would not finish its conversion. and the `HAL_JPEG_EncodeCpltCallback` is not called.My setup is based on the `JPEG...
Hi to all!,I try to run a Gui designed with TouchGFX on my hardware ( a Nucleo-F767ZI board and a 7" display with touchscreen).I have created a new c++ project for doing this and I have selected the LL implementations of the periphericals that i use ...

Hi Team I faced an issue while using STM32H7B3I-DK I connected it to the STMIDE programmer and flashed the code later i see that the display screen was not working I see that flashing the code has gone wrong I currenlty see only red led light blinkin...
i've got a "low cost" dev board with STM32F429BI SOC and 5inch touch LCD, and i'm praticing with the current CubeIde 1.3.1 / TouchGfx 4.13 CubeMX framework.i followed the instruction for a new bring-up and they are pretty enlightning! the TouchGfx bo...
Hello Martin,My platform is stm32l4r7zi, which uses ltdc to drive 800 × 480 LCD in the way of rgb565 connection. Because the internal RAM (640kb) is not large enough for frame buffer, so I want to select 8bit color depth in the touch designer. Can th...
