    Hi, Awesome, I can confirm with 0 io 20 as version it works now! And thanks for the version information, i just took something in the middle of the range thinking middle is good :) without really knowing what it does. Since it seems unlikely we will ever…

    Hi, Any updates on this ? Is there maybe a possibility to give me just the sources for the QR generator part so I can check here what is going on ? If not I think i will just use some other QR generator code and draw the matrix myself, but it is a bit…

    Hi, GUI_Init() is called via STemwin_wrapper.c/GRAPHICS_Init() This happens before Freertos is started, while the DISPLAY_Init is called from a Freertos task (i hope there is no restriction there ?). At the moment I only use the "primitive" drawing…

    Hi, I am using stemwin (version 5.44) on an STM32F429 I am calling Source Code (6 lines) but sadly this triggers an exception handler. Looking at the program counter in the exception frame i see I am in GUI_ALLOC_Free. I have put a breakpoint on the…

    Ah thank you, I see in GUI.h "emWin V5.44". How old are these ? I see release notes on segger.com/products/user-interface/emwin/ but there are no dates mentioned. Not sure if there is a way to get recent stemwins given to move to touchgfx from st :(

    Hi, I was just trying to use GUI_BARCODE_Draw in STemWin but it turns out the function is missing (along with GUI_QR_CreateFramed, but GUI_QR_Create exists so I can make the framed variant myself). Was this not licensed by ST or something ? Or was…

    Ok thank you very much ! (In the meantime I had made a translation layer to reformulate ST7735 commands into SSD2119 ones, but I will change this to the "native" method then)

    Hi, I am trying to use the st precompiled stemwin on an stm32f4 but with an SSD2119 controller. This is controller not selectable in the cubemx SW, though SSD1355 is. If I toggle between the SSD1355 and ST7735 (a controller i used successfully in the…
