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.

RTuinOS, the event based Real-Time Operating System (RTOS) for Arduino, is now hosted at SourceForge. In this revision, 1.0, the event concept has been generalized. Events can now be broadcasted events, semaphores or mutexes. This permits to implement all the usual inter-task communication patterns. Please refer to the user guide and the diverse code samples for details.

...A key design objective is to use as little dedicated hardware as possible for communication between nodes in the network, and to be able to adapt the network topology in real-time so as to minimize the occurrence of collisions between packets. To achieve this, a protocol has been designed specifically for the task, and implemented in assembler for AVR microcontrollers. The project is currently at the stage of testing the protocol for bugs and implementing some simple devices which use it.

The system uses internal databases to store led information such as pin number, target brightness, time at which the brightness should be reached and current program number. When the target is reached the led looks for the next program and get new time and brightness. Leds and programs can be manipulated on the fly, in the program or from serialusb. A very simple task scheduler call the update of leds every 5ms, leaving plenty of processor for other tasks.
