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 ...
I started out by using the stock 4.3" display on the STM32H735G-DK Discovery Kit and with TouchGFX I was able to get a nice example project running. Now I am attempting to interface a 7" 800x480 LCD panel with the kit. This panel uses the EK9713CA ...
I've been able to successfully use Bitmap::dynamicBitmapCreateExternal() when just loading a bitmap in the frontendappliation and setting up the cache there...FrontendApplication::FrontendApplication(Model& m, FrontendHeap& heap) : FrontendApplic...
Hi,I've recently migrated to TouchGFX v4.25. The changelog seems to indicate that we can now store our texts in an unmapped external flash, for example an SPI flash. When going through the following page of the documentation :https://support.touchgfx...
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...
