Contiki – Open Source Multi-Tasking OS

Contiki is an open source, highly portable, multi-tasking operating system for memory-efficient networked embedded systems and wireless sensor networks. Contiki has been used is a variety of projects, such as road tunnel fire monitoring, intrusion detection, water monitoring in the Baltic Sea, and in surveillance networks.

Contiki – Open Source Multi-Tasking OS

Contiki is designed for microcontrollers with small amounts of memory. A typical Contiki configuration is 2 kilobytes of RAM and 40 kilobytes of ROM.

Contiki provides both full IP networking and low-power radio communication mechanisms. For communication within wireless sensor network, Contiki uses the Rime low-power radio networking stack.

The M-12 module from Redwire is a fast and easy way to create a 6LoWPAN, Zigbee, or general 2.4GHz 802.15.4 device without additional RF design or certifications and without the need for an external host microcontroller. This is a Hardware for Contiki.



Instant Contiki
is a complete development environment in a single-file download: a virtual machine with all Contiki software development tools installed. All that is needed to start using and developing Contiki software is the free VMWare Player software, 4 Gb free hard drive space, and the Instant Contiki development environment.

Updated Oct 2013

Contiki is an open source operating system for the Internet of Things. Contiki connects tiny, low-cost, battery-operated and low-power systems to the Internet.

The Internet of Things is a collection of technologies that connect things-sensors and actuators-to the Internet, allowing the physical world to be accessed through software.
