The open source version of the embedded graphical library is available here:
Website: https://lvgl.io
GitHub: https://github.com/lvgl/lvgl
Graphical effects which typically use double buffering (e.g. transparency) handled in the library without external memory even with high resolution displays. Only a general microcontroller is needed.
The used display's resolution is 480 x 320. The display board contains a display controller IC which acts as a simple frame buffer.
