\mainpage The Contiki Operating System

\author Adam Dunkels <[e-mail]>

The Contiki operating system is a highly portable, minimalistic
operating system for a variety of resource constrained systems with
memory size on the order of a few kilobytes. 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 in the C programming language and is freely
available as open source under a BSD-style license. More information
about Contiki can be found at the Contiki home page:

The ESB (Embedded Sensor Board) is a prototype wireless sensor network
device developed at Freie Universit鋞 Berlin. The ESB consists of a
Texas Instruments MSP430 low-power microcontroller with 2k RAM and 60k
flash ROM, a TR1001 radio transceiver, a 32k serial EEPROM, an RS232 port, a
JTAG port, a beeper, and a number of sensors (passive IR, active IR
sender/receiver, vibration/tilt, microphone, temperature).

The Contiki/ESB port brings support for TCP/IP, loadable programs
(over-the-air programming), event-based multitasking, and cooperative
multi-threading (preemptive threading is implemented but not yet fully
tested) to the ESB. The Contiki/ESB port contains drivers for most of
the sensors. The drivers were mostly adapted from sources written by
FU Berlin.

\section contiki-esb-threads Processes, multi-threading and protothreads

Contiki is based on an event-driven kernel but provides support for
both multi-threading and a lightweight stackless thread-like construct
called protothreads.

\section contiki-esb-communication Communication

Contiki includes the uIP TCP/IP stack (http://www.sics.se/~adam/uip/)
that provides Contiki with TCP/IP networking support. uIP provides the
protocols TCP, UDP, IP, and ARP.

In Contiki, the TCP/IP stack typically is used for all communication.

\section contiki-esb-lib Libraries

Contiki provides a set of convenience libraries for memory management
and linked list operations.
