RT-Thread | Thread RTOS

RT-Thread is a C library. RT-Thread has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

RT-Thread RTOS like a traditional real-time operating system. The kernel has real-time multi-task scheduling, semaphore, mutex, mail box, message queue, signal etc. However, it has three different things:. The device driver is more like a driver framework, UART, IIC, SPI, SDIO, USB device/host, EMAC, MTD NAND etc. The developer can easily add low level driver and board configuration, then combined with the upper framework, he/she can use lots of features. The Component is a software concept upon RT-Thread kernel, for example a shell (finsh/msh shell), virtual file system (FAT, YAFFS, UFFS, ROM/RAM file system etc), TCP/IP protocol stack (lwIP), POSIX (thread) interface etc. One component must be a directory under RT-Thread/Components and one component can be descripted by a SConscript file (then be compiled and linked into the system). The Dynamic Module, formerly named as User Applicaion (UA) is a dynamic loaded module or library, it can be compiled standalone without Kernel. Each Dynamic Module has its own object list to manage thread/semaphore/kernel object which was created or initialized inside this UA. More information about UA, please visit another git repo.
