StateOS

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 in preemptive or cooperative mode
• 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)
• cmsis-rtos api
• cmsis-rtos2 api
• nasa-osal support
• c++ wrapper
• all documentation is contained within the source files
• examples and templates are in separate repositories
