RT-Thread born in 2006, it's an open-source, neutral, and community-based real-time operating system (RTOS). The software has the characteristics of very low resource occupancy, high reliability, high scalability, can be greatly used in sensing nodes, wireless connection chips and many resource-constrained scenes, also widely applied in gateway, IPC, smart speakers, and many other high-performance applications. RT-Thread is also considered as an IoT platform with its rich middle-tier components and great hardware and software ecosystem, with almost every key basic component required for IoT devices, such as network protocols, file systems, low power management, etc. It supports all mainstream compiling tools such as GCC, Keil, IAR, etc., and a variety of standard interfaces, such as POSIX, CMSIS, C++application environment, Micropython, and Javascript, easy for developers to port a wide range of applications. RT-Thread also offers great commercial support to all the mainstream CPU architectures such as ARM Cortex-M/R/A, RISC-V, MIPS, X86, Xtensa, etc. We and the community strives to create a New Class of IoT operating system with great hardware and software ecosystem, get everything connected, keep information flowing, and make opensource project benefits more people!
