Up to now there are a lot of graphical libraries for STM32.
The most popular are listed below.

Tutorial and extra doc are here.

STM-TouchGfx – TouchGFX is an advanced free-of-charge graphic software framework optimized for STM32 microcontrollers.
Taking advantage of STM32 graphic features and architecture, TouchGFX accelerates the HMI-of-things revolution through the creation of stunning, smartphone-like graphic user interfaces.
TouchGFX makes GUI development easy, combining WYSIWYG simulator and automatic code generation.

STemWin

Thanks to a partnership with SEGGER Microcontroller GmbH, STM can provide the STemWin solution, based on SEGGER emWin one.

This library is a professional graphical stack library, enabling the building up of Graphical User Interfaces (GUIs) with any STM32, any LCD/TFT display and any LCD/TFT controller, taking advantage of STM32 hardware accelerations whenever possible.

STemWin is provided under binary form to any STM32 customer, for free.

STemWin Library is a comprehensive solution coming with rich features such as JPG, GIF and PNG decoding, many widgets (checkboxes, buttons…) and a VNC server allowing to display remotely a local display, but also professional development tools such as GUIBuilder to create GUIS with simple drag and drop.

Key Features

  • Rich set of widgets (buttons, checkboxes, calendars, gauges, …)
  • Window and overlap manager
  • Full set of Development tools: GUIBuilder to create screens, Font converter, simulator, etc.
  • Free professional graphical stack library available in binary form
  • Memory-sparing features (memory pool, per band screen creation, refresh only changed portions, …)
  • Able to handle many kinds of displays with optimized mechanisms
  • Alpha blending, Antialiasing, Cursors
  • VNC server to display remotely the display via VNC protocol (based on TCP/IP)
  • Raw graphical renderer (Pixels, Shapes, Fonts, …)
  • Optimization using STM32 Chrome-ART HW accelerator to decrease the CPU load.

NOTE:

Now the STemWin library and documentation are inside the HAL Libraries.

For example, in the STM32F7 library there is a directory in which there is an extensive documentation about the SEGGER graphics libraries (STemWIN).
Download the HAL library, unpack it and look in the directory below.
C: \ ….. \ STM32Cube_FW_F7_V1.2.0 \ Middlewares \ ST \ STemWin

In the directory below, there is an example for the STM32F7-DISCOVERY, which uses Segger libraries .
All STM examples are refered to the SEGGER examples that are here.
Read the: readme.txt file that is located in:
C: \ ….. \ STM32Cube_FW_F7_V1.2.0 \ Projects \ STM32746G-Discovery \ Applications \ STemWin \ STemWin_HelloWorld
The main directory is this:
C: \ ….. \ STM32Cube_FW_F7_V1.2.0 \ Projects \ STM32746G-Discovery \ Applications \ STemWin
