## What is RT-Thread?

[**RT-Thread**](https://www.rt-thread.io/) is an [open source](https://github.com/RT-Thread/rt-thread), neutral, and community-based real-time operating system (RTOS). RT-Thread has **Standard version** and **Nano version**. For resource-constrained microcontroller (MCU) systems, the Nano version that requires only 3 KB Flash and 1.2 KB RAM memory resources can be tailored with easy-to-use tools. For resource-rich IoT devices, RT-Thread can use the **online software package** management tool, together with system configuration tools, to achieve intuitive and rapid modular cutting, seamlessly import rich software packages; thus, achieving complex functions like Android's graphical interface and touch sliding effects, smart voice interaction effects, and so on.

Key features:

- Designed for resource-constrained devices, the minimum kernel requires only 1.2KB of RAM and 3 KB of Flash.
- A variety of standard interfaces, such as POSIX, CMSIS, C++ application environment.
- Has rich components and a prosperous and fast growing <a href="https://packages.rt-thread.org/en/">package ecosystem</a>
- Elegant code style, easy to use, read and master.
- High Scalability. RT-Thread has high-quality scalable software architecture, loose coupling, modularity, is easy to tailor and expand.
- Supports high-performance applications.
- Supports all mainstream compiling tools such as GCC, Keil and IAR.
- Supports a wide range of <a href="https://www.rt-thread.io/board.html">architectures and chips</a>.



## How to run LVGL on RT-Thread?

[中文文档](https://www.rt-thread.org/document/site/#/rt-thread-version/rt-thread-standard/packages-manual/lvgl-docs/introduction)

LVGL has registered as a [software package](https://packages.rt-thread.org/en/detail.html?package=LVGL) of RT-Thread. By using [Env tool](https://www.rt-thread.io/download.html?download=Env) or [RT-Thread Studio IDE](https://www.rt-thread.io/download.html?download=Studio), RT-Thread users can easily download LVGL source code and combine with RT-Thread project. RT-Thread community has port LVGL to several BSPs:
