STemWin & GIF image & MULTIBUF

I did make a project for DiscoveryF746 & CubeMX 4.25.1 with the window with GIF image (my avatar).

For GUI_App.c file

the angel does not wave his wings for setting (as well as on my avatar) 

WM_MULTIBUF_Enable(1);

Angel wings for setting

WM_MULTIBUF_Enable(0);

Why is that?

}

}

If you use the IMAGE_SetGIF () function, keep track of the frame addresses yourself.

Hello,

vitalik180887

I have problems not only with the image.

The project is launched under the condition

//WM_MULTIBUF_Enable(1);

or

WM_MULTIBUF_Enable(0);

BUT! If I compile the project with the condition

WM_MULTIBUF_Enable(1);

After the power is turned off and on...

a project does not start...

Hello! Everything works! I'm using stm32f746IGT! I can throw off my project! You will need to remake to your controller!
