It's supported by industry leading vendors and projects like  Arm, STM32, NXP, Espressif, Nuvoton, Arduino, RT-Thread, Zephyr, NuttX, Adafruit and many more. **Feature Rich**<br> It has all the features to create modern and beautiful GUIs: 30+ built-in widgets, a powerful style system, web inspired layout managers, and a typography system supporting many languages. To integrate LVGL into your platform, all you need is at least 32kB RAM and 128 kB Flash, a C compiler, a frame buffer, and at least an 1/10 screen sized buffer for rendering. **UI Editor**<br> SquareLine Studio is a professional yet affordable drag and drop UI editor for LVGL. It runs on Windows, Linux and MacOS too and you can try it out even without registering to the website. **Services**<br> Our team is ready to help you with graphics design, UI implementation and consulting services. Contact us if you need some support during the development of your next GUI project. ## :rocket: Features **Free and Portable** - A fully portable C (C++ compatible) library with no external dependencies. - Can be compiled to any MCU or MPU, with any (RT)OS. - Supports monochrome, ePaper, OLED or TFT displays, or even monitors. [Porting Guide](https://docs.lvgl.io/master/porting/project.html) - Distributed under the MIT licence, so you can easily use it in commercial projects too. - Needs only 32kB RAM and 128 kB Flash, a frame buffer, and at least an 1/10 screen sized buffer for rendering. - OS, External memory and GPU are supported but not required. **Widgets, Styles, Layouts and more** - 30+ built-in [Widgets](https://docs.lvgl.io/master/widgets/index.html):  Button, Label, Slider, Chart, Keyboard, Meter, Arc, Table and many more. - Flexible [Style system](https://docs.lvgl.io/master/overview/style.html) with  ~100 style properties to customize any part of the widgets in any state. - [Flexbox](https://docs.lvgl.io/master/layouts/flex.html) and [Grid](https://docs.lvgl.io/master/layouts/grid.html)-like layouts engines to automatically size and position the widgets in a responsive way. - Texts are rendered with UTF-8 encoding supporting CJK, Thai, Hindi, Arabic, Persian writing systems. - Word wrapping, kerning, text scrolling, sub-pixel rendering, Pinyin-IME Chinese input, Emojis in texts. - Rendering engine supporting animations, anti-aliasing, opacity, smooth scrolling, shadows, image transformation, etc   - Supports Mouse, Touchpad, Keypad, Keyboard, External buttons, Encoder [Input devices](https://docs.lvgl.io/master/porting/indev.html). - [Multiple display](https://docs.lvgl.io/master/overview/display.html) support. **Binding and Build Support** - [Micropython Binding](https://blog.lvgl.io/2019-02-20/micropython-bindings) exposes LVGL API - No custom build system is used. You can build LVGL as you build the other files of your project. - Support for Make and [CMake](https://docs.lvgl.io/master/get-started/platforms/cmake.html) is included out of the box. - [Develop on PC](https://docs.lvgl.io/master/get-started/platforms/pc-simulator.html) and use the same UI code on embedded hardware. - Convert the C UI code to HTML file with our [Emscripten port](https://github.com/lvgl/lv_web_emscripten). **Docs, Tools, and Services** - Detailed [Documentation](https://docs.lvgl.io/) with [100+ simple examples](https://docs.lvgl.io/master/index.html) - [SquareLine Studio](https://squareline.io/) - A professional and easy-to-use UI editor software to speed up and simplify the UI development. - [Services](https://lvgl.io/services) such as User interface design, Implementation and Consulting to make UI development simpler and faster. ## :heart: Sponsor If LVGL saved you a lot of time and money or you just had fun using it, consider [Supporting its Development](https://opencollective.com/lvgl). **How do we spend the donations?**<br> Our goal is to provide financial compensation for people who do the most for LVGL. It means not only the maintainers but anyone who implements a great feature should get a payment from the accumulated money. We use the donations to cover our operational costs like servers and related services. **How to donate?**<br> We use [Open Collective](https://opencollective.com/lvgl) where you can easily send one time or recurring donations. You can also see all of our expenses in a transparent way. **How to get paid for your contribution?**<br> If someone implements or fixes an issue labeled as [Sponsored](https://github.com/lvgl/lvgl/labels/Sponsored) he or she will get a payment for that work. We estimate the required time, complexity and importance of the issue and set a price accordingly. To jump in just comment on a [Sponsored](https://github.com/lvgl/lvgl/labels/Sponsored) issue saying *"Hi, I'd like to deal with it. This is how I'm planning to fix/implement it...". A work is considered ready when it's approved and merged by a maintainer. After that you can submit and expense at [opencollective.com](https://opencollective.com/lvgl) and you payment will be sent in a few days. **Organizations supporting LVGL**<br> [](https://opencollective.com/lvgl) **Individuals supporting LVGL**<br> [](https://opencollective.com/lvgl) ## :package: Packages LVGL is available as: - [Arduino library](https://docs.lvgl.io/master/get-started/platforms/arduino.html) - [PlatformIO package](https://registry.platformio.org/libraries/lvgl/lvgl) - [Zephyr library](https://docs.zephyrproject.org/latest/reference/kconfig/CONFIG_LVGL.html) - [ESP32 component](https://docs.lvgl.io/master/get-started/platforms/espressif.html) - [NXP MCUXpresso component](https://www.nxp.com/design/software/embedded-software/lvgl-open-source-graphics-library:LITTLEVGL-OPEN-SOURCE-GRAPHICS-LIBRARY) - [NuttX library](https://docs.lvgl.io/master/get-started/os/nuttx.html) - [RT-Thread RTOS](https://docs.lvgl.io/master/get-started/os/rt-thread.html) - NXP MCUXpresso library - CMSIS-Pack ## :robot: Examples See some examples of creating widgets, using layouts and applying styles.
