ChibiOS/NIL

NIL has been created with the idea to bring RTOS functionalities to very small devices and yet to be a full-fledged RTOS.

In Brief

• Tiny RTOS, below 1kB of code space in its maximum configuration.
• Small size of memory objects like Thread, Semaphores etc.
• Fully static architecture.

Regardless its size NIL is very efficient and supports a rich set of features.
