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 ...
On our custom board running STM32U5G7 I have set up a project using the same configurations in the .ioc file of the STM32U5G9J-DK2 but obviously with our pinout and package. The project compiles and runs, it does display correctly on the sim but ther...
I've been working on a board bring up of a STM32U5G7 for a few days following https://support.touchgfx.com/docs/development/board-bring-up/board-introductionWhile the board is able to display the framebuffer and change colours, etc, when I finally co...
Hello,I am working on an STM32H743 project where:My external QSPI Flash is mapped at 0x90000000.My external SDRAM (via FMC) is mapped at 0xC0000000.I have MPU regions set up for QSPI and SDRAM (with caching and write-through).Everything works perfect...
Hi ST community,I am developing firmware on the STM32H743 and I store the images and texts in BANK1 of an external Flash memory, specifically the 8MB MX25R6435F. To update my firmware, I write the new images, fonts, and texts to BANK2 (0x90400000) in...
Hello, I am working with a custom board using an STM32u5g9vjt6q and a DSI display in video mode. The screen consist of multiple elements including scrollwheels, text boxes, arcs and boxes with borders and using the double buffer strategy Originally...
Hello, I've been working on stm32u5g9j dk1 board, with a 466 * 466 oled display that I've changed.It works great with bitmap widgets, or vector widgets on a software rendering.But if I change it to hardware rendering to use neochromVG, the display on...
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 wanted to ask if theX-NUCLEO-GFX01M2 module is compatible with STM32 NUCLEO-H533RE? The official documentation does not say anything about this NUCLEO board.Kind regards Andrew
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 ...
