The Contiki Operating System is mostly known as an operating system for networked embedded systems. A few years ago, however, Contiki's primary claim to fame was its Commodore 64 port.
With the help of JAC64, a Java-based C64 emulator developed by my colleague and fellow Contiki developer Joakim Eriksson, you can now experience the C64 port of Contiki 1.2-devel1 again, directly in your web browser!

What's New in This Release: [ read full changelog ]
ContikiRPL:
· ContikiRPL is a new implementation of the proposed IETF standard RPL protocol for low-power IPv6 routing. ContikiRPL now is the default IPv6 routing mechanism in Contiki.
ContikiMAC:
· The new ContikiMAC state-of-the-art low-power listening asynchronous radio duty cycling mechanism is now the default duty cycling mechanism in Contiki.
Contiki Collect:
· Contiki Collect is an address-free data collection protocol that runs on top of the Contiki Rime stack. For Contiki 2.5, Contiki Collect has been completely reworked to provide a significantly improved performance as well as configurability.
CollectView:
· CollectView is a Java GUI that is used to set up a Contiki data collection network, either over Contiki collect or over UDP/IPv6/RPL.
Powertrace:
· Powertrace is an interface to the Contiki power profiling system that allows either real-time inspection or off-line analysis of the power consumption of a sensor network.
The Contiki simulation environment:
· The MSPSim/Cooja simulation environment has received a significant speed-up.
CoAP/REST:
· Contiki 2.5 includes an experimental implementation of the IETF CoRE group’s CoAP application layer protocol for RESTful interaction with a low-power IP sensor network.
New platforms:
· Zolertia Z1, RedWire Econotag mc13224v, ST Microelectronics STM32w, Sentilla JCreate.
