GuiLite - The smallest UI framework

What is GuiLite?

  • GuiLite, a tiny and light framework, has only 5000 lines of C++ code, supporting all computing platforms. It could run on iOS, Android, GNU/Linux, Windows, macOS and all ARM Linux IOT platforms.
  • GuiLite is without reference to OS & Grphic library, it even could run on any kind of MCU without OS.
  • GuiLite is an embedded framework. It can work with an another UI framework such as Qt/MFC/UWP/XCode, which means you can get not only GuiLite features but also iOS/Android/macOS/Qt/MFC/UWP features on your project.
  • GuiLite can work with other languages(e.g. Swift, Java, C#).
  • ⚠️We never encourage people accept GuiLite totally and uncritically, but want people master principles of UI itself.
  • ⚙️We hope GuiLite is small enough to help you understand how UI work, and build unique UI yourself.
  • 👑You should be the master of your UI, not any UI library (including GuiLite).

New feature: MCU demos: HelloMario + HelloParticle + HelloWave

HelloMario        HelloParticle        HelloWave;

  • MCU Hardware: STM32F103ZET6(512K ROM, 64K RAM) + 240*320 16bits color TFT LCD
  • MCU Software: None OS + GuiLite
  • Hello Mario has 100+ lines code! Check the code, showing you how to develop a multi-layer UI system.
  • Hello Particle 100- lines code! Check the code, showing you how to develop a particle system.
  • Hello Wave has 100+ lines code! Check the code, showing you how to use the wave widget.
  • How to porting on any MCU in 5 minutes?
  • Also support: Windows & Linux
