tired it with simulated working ok. but when i put that code in STM IDE its show error when complie
The problem is likely to be the different LVGL major version. The exported code is LVGL 8.3 compatible, but LVGL9 contained API-changes, one of them is the structs/enumerations of colors/images. I guess you should ensure that LVGL 8 is set/included in STM IDE, not the newest LVGL major version 9.
Hi Hermit thanks for your comment. I had switched version to 8.3.11. built the code that part error is removed but some other error raised as below
It seems the Cube-IDE compiler has problems with missing functions, i.e. missing header inclusions. I guess you should set lvgl, display-driver, etc. include paths in CubeIDE for the project if it’s not done automatically by some automatic library-selection menu. ( a forum-link after a fast web-search: Where to add new .h and .cpp file in STM32CubeIDE project - Stack Overflow )
Checking the lv_port_stm32f746 github page reveals there’s also a CMake-based build.sh, maybe you can try building a demo with that as a starting point, then if it works, build your own project with included ui/drivers/etc. (But CMake also needs some inclusions for the added extra libraries, be it driver/lvgl/ui/watever. )
