The LittlevGL is a graphics library which allows you to create graphical user interfaces (GUI) from the most simple monochrome designs to amazing GUIs for high resolution TFTs. No double buffering is required to use transparency and smooth animations.
The LittlevGL is a graphics library to create Graphical User Unterfaces (GUI) for TFT and LCD displays. You can use Buttons, Labels, Charts etc to build up your GUI.No double buffering is required to use transparency, scrolling or smooth animations.
The graphics library is written in C and it is completely hardware independent. You can even run it in a PC simulator without any embedded hardware.
