This repository is a working implementation of LVGL (Little and Versatile Embedded Graphics Library) on Raspian with the official 7" LCD screen.
This implementation uses the linux frame buffer interface.
Download the repository on your Pi and run make in the lvgl_demo directory.
The code should compile without errors and you should end up with an excutable file named demo in the lvgl_demo directory.
The executable file must be run with root permission to allow access to the frame buffer device:
sudo ./demo
