Overview


Thanks to its partner SEGGER, ST is providing the STemWin Library, based on SEGGER emWin one. STemWin is a professional graphical stack library, enabling Graphical User Interfaces (GUI) building up with any STM32, any LCD and any LCD controller, taking benefit from STM32 hardware accelerations, whenever possible.
STemWin Library is a full solution, coming with services like JPG, GIF, PNG decoding, tons of Widgets (check boxes, buttons, …), the VNC server allowing remote displaying of what is displayed locally, but also professional tools: the GUIBuilder, allowing on PC screens creation, via drag and drop, the Simulator, allowing to develop and debug one interface on the PC, Font Converter...
