* Preemptive scheduler with 255 priority levels * Round-robin at same priority level * Lightweight: the entire operating system fits into a few C files * Highly portable ANSI C code not tied to any compiler * Easy to read, well-documented, doxygen-commented code * Can be ported to any CPU architecture with a single architecture-specific module * Automated test suite proves reliable kernel operation * Free and flexible open source, BSD-licensed code * Readable code provides a good platform for learning RTOS internals

* Task procedures can be outlined in the same style as when using a traditional preemptive RTOS. * cocoOS is extremely portable to any target which makes it a perfect choice during early phases in the development when which OS to use is still an open issue. * cocoOS is released under a BSD license.
