StateOS

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
