Contiki

The Contiki Operating System

Contiki is an open source, highly portable, networked, multi-tasking operating system for memory-constrained systems.

The Contiki operating system is a highly portable, minimalistic operating system for a variety of constrained systems ranging from modern 8-bit microcontrollers for embedded systems to old 8-bit homecomputers. Contiki provides a simple event driven kernel with optional preemptive multithreading, interprocess communication using message passing signals, a dynamic process structure and support for loading and unloading programs, native TCP/IP support using the uIP TCP/IP stack, and a graphical subsystem with either direct graphic support for directly connected terminals or networked virtual display with VNC or Telnet.

Contiki is written entirely in the C programming language and features:

* Multi-tasking kernel with loadable programs and drivers. * Optional preemptive multi-threading, on per-application basis. * TCP/IP networking. * Windowing system and GUI. * Networked remote display.. * Personal webserver. * The world's smallest web browser. * Simple telnet client. * Screen-saver. * With more applications under development.

Contiki is highly portable; since its release in March 2003, Contiki has been ported to over 20 different platforms.
