Hello,
I am writing to you because I need help to solve my problem.
Here is the situation:
I am learning to use emWin. I use an OLed screen with an SSD1305 controller. it's a monochrome screen.
Currently I communicate by SPI bus.
ST does not provide a driver for this type of screen. So I wrote a driver.
emWin works very well, buttons, animations, keyboard ...
However, for everything to work well I need to use MEMDEV.
If I don't configure a MEMDEV, emWin does not show me all the elements.
The animation works but when I hide window n°2, only the animated part of window n°1 hides window n°2
The window n ° 2 is of dimension 45x64
I would like to know, if I don't want to use a MEMDEV, do I need a specific setting? I have been searching for several days, without results, and I cannot understand why such behavior.

GUI_PORT_API PortAPI={0};
