FT81x LVGL with STM32

[blindelectronics]

Does anybody know how to port FT81x to LVGL I am using STM32H7.
I found this...
https://gitlab.com/nucleo-f446ze-sandbox/f446ze-lvgl-test/-/blob/master/FT812/tft.c
It is way too difficult for my taste

So I found this...
https://github.com/controllerstech/STM32/blob/master/LVGL/Simple_F446/Core/Src/lcd_lvgl.c
I just need to change command: fillFB(area->x1, y, area->x2, y, DISP_fb);
with classic FT81x command. (using this official library https://github.com/MatrixOrbital/EVE2-Library)
Thank you for help and ideas
