Free, extremely simple and amazingly tiny 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.
Features #

- kernel can operate with 16, 32 or 64-bit timer counter
- kernel can operate in tick-less mode
- 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
- memory pools
- stream buffers
- message buffers
- mailbox queues
- event queues
- job queues
- timers (one-shot, periodic)
