RT-Thread RTOS

What is RT-Thread?

RT-Thread is an open source, 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 package ecosystem

  • 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 architectures and chips.
