"LVGL" (Light and Versatile Graphics Library) is an open-source embedded GUI library that is written in C (with C++ compatibility) and is released under the MIT license. It’s optimized for deployment on micro-controllers and bare metal (no OS) devices, but on this article, we will see how to develop LVGL applications for our STM32MP1 microprocessor that runs the OpenSTLinux linux distribution.

1.1.2. SDL2

SDL or Simple Direct Media Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. it allows to show windows, show images, play sounds, manage keyboards... SDL is written in C, works natively with C++, and there are bindings available for several other languages, including C# and Python. SDL 2.0 is distributed under the zlib license. This license allows you to use SDL freely in any software.
