Hello, i'm trying to incorporate TouchGFX into STM32CubeIDE with project based on STM32F767BIT6 (2MB Flash). Without TouchGFX the project can be build with size about 170kB. I updated STM32CubeIDE from 1.14.1 on 1.15.0 and i dont have working Build A...

Hello,i have TFT with resolution 800x480 @ 24bpp connected to the STM32F767BIT6 with external SDRAM IS42S16400J-7TL.The MCU is running on 216MHz, thus FMC on 108MHz, SDRAM as CAS latency = 2 and LTDC pixel clock 19,2MHz(able to run on 24MHz too) with...

Hello,i have custom made board assembled by STM32F767BIT6 and external SDRAM IS42S16400 for video buffers.The MCU runs at maximum speed 216MHz. LTDC seems to work fine bud when i use dual layer, the second layer seems that reading from external SDRAM...

Now it works! I unchecked Binary font files box in Config -> Text Configuration and all texts are visible in simulator and hardware.

No, i put initial value in the TouchGFX Designer only. I didn't change the string by my custom firmware yet. I can try call that in the method screenView::setupScreen()

I removed TouchGFX from the STM32CubeIDE project and deleted TouchGFX folder. Then again compiled it without errors. Again add TouchGFX project and now it can be compiled without overflow errors.But still dont have working Build Analyzer(empty memory...

Thank you for the post thread, that sounds interesting Exactly, i have own graphic render compilation because i'm not familiar with TouchGFX or LVGL working together with STM32CubeIDE. I have to find some user guide for it. The hardware i made conta...
