      Hello, can anyone give example of how to draw bitmap from input RGB888 from memory to output ARGB8888 in some LCD lay?
      I'm using STM32H743I-eval board with another LCD 1024x768. Any graphical figures draws good.
      Is appear any emWin functions or i have to define my custom function for drawing?
      I see some close for my question, and this code seems have to work:

      C Source Code

      1. #define LCD_LAYER0_FRAME_BUFFER ((int)0xD0000000)
      2. #define LCD_LAYER1_FRAME_BUFFER ((int)0xD0400000)
      3. uint8_t *uwInternelBuffer = (uint8_t *)0xD0A00000; // Here is my RGB888 data
      4. static GUI_BITMAP picture;
      5. picture.XSize = 1024;
      6. picture.YSize = 768;
      7. picture.BytesPerLine = 1024 * 3;
      8. picture.BitsPerPixel = 24;
      9. picture.pPal = NULL;
      10. picture.pMethods = GUI_DRAW_BMP8888;
      11. picture.pData = (unsigned char *)uwInternelBuffer;
      Display All
      but i see corrupted picture.
