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 ...
Use sthm32h7b0 to push 800*480 TFT screen, using internal ram，using RGB565 color space. Run the test function lv_demo_widgets(), it can work normally under lvgl8.2. fter lvgl was upgraded from version 8.2 to version 9.1, after modifying the correspon...
Hello everyoneI recently bought an STM32H735G-DK Discovery Kit, which has a 480x272 parallel LCD. I got the TouchGFX Demo projects running on the board, so I know all the hardware is working as it should.Eventually I want to use TouchGFX on a custom ...
Hi, I am trying to create an external dynamic bitmap to display an image already loaded into Memory Mapped External Flash. uint16_t FrontendApplication::getLogoBitmapId() { if (bitmapId == touchgfx::BITMAP_INVALID) { bitmapId = Bitmap::d...
Hello,I download an example GUI from Touchgfx designer, generate code and run on my STM32H735G-DK board, it works well.Then I open the .ioc of this project and generated code with EWARM, open it and build, it has no errors.When I download it to board...
Hi, I am creating a DynamicBitmapCreateExternal() for RGB565, but the image shows up faded. Is there any fix for this? I made sure to set cache for it. I also tried for L8 and it didn't show.
For STM32H743IIT6, the external font library used in TouchGFX is stored in a USB flash drive. After power - on, it is loaded into SDRAM. When displaying text, some fonts appear garbled. The font library I added covers Unicode range from 0x4e00 to 0x4...
Hi!I'm developing an application in the simulator, I'm stuck on one bug with the scrollWheel. I have done these two scrollWheel that i update on their respective callbacks like this:void Display_Stages::m_scroll_pressureUpdateItem (Item_To_Select &it...
Hello,I am attempting to use an STM32H735G-DK development kit to drive an LCD and eventually use TouchGFX to build a menu for a proof of concept I'm working on. I was able to very quickly get a working screen using TouchGFX example board setup for t...
I have spent several weeks trying to add an external loader for a TouchGFX application that is starting to get quite large (>2MB). I have a custom board with STM32H7A3 and am using OCTOSPI interface (in quad mode) to a W25Q128. I found a custom loade...
I am trying put a ScrollWheelWithStyle inside a ScrollContainer.Currently I can't find a method to pass down dragEvents from the Container to the Wheel.I tried disabling the scrolling for the Container.This cause the areas to initiate the draggable t...
