Free, extremely simple, amazingly tiny and very fast real-time operating system (RTOS) designed for deeply embedded applications.
Target: ARM Cortex-M, STM8.
It was inspired by the concept of a state machine. Procedure executed by the task (task state) doesn't have to be noreturn-type. It will be executed into an infinite loop. There's a dedicated function for immediate change the task state.

Features

  • kernel can operate in preemptive or cooperative mode
  • kernel can operate with 16, 32 or 64-bit timer counter
  • kernel can operate in tick-less mode
  • implemented basic protection using MPU (use nullptr, stack overflow)
  • spin locks
  • once flags
  • events
  • signals with protection mask
  • flags (any, all, protect, ignore)
  • barriers
  • semaphores (binary, limited, counting)
  • mutexes with configurable type, protocol and robustness
  • fast mutexes (error checking)
  • condition variables
  • read/write locks
  • memory pools
  • stream buffers
  • message buffers
  • mailbox queues
  • event queues
  • job queues
  • timers (one-shot, periodic)
  • cmsis-rtos api
  • cmsis-rtos2 api
  • nasa-osal support
  • advanced c++ wrapper
  • all documentation is contained within the source files
  • examples and templates are in separate repositories (https://github.com/stateos)
