Sedona Framework for Developers

In August 2009 Tridium officially launched the Sedona Framework. This can be described as a new “micro” version of Niagara, which extends the reach of our technology to much smaller platforms, enabling these to be reconfigured via network connections for the first time. Instead of small devices having to be programmed with a fixed set of functions such devices running Sedona Framework code can be dynamically re-configured, wirelessly if deisred.

Until now the vast majority of small control devices have been fixed function; they are programmed at the design stage to perform a set of functions and this is hard-coded into the product. Although some configuration settings can be changed by the installer/user the basic functionality is designed in. With Sedona Framework technology the small control device can be reconfigured at will using a Niagara AX based s/w tool, introducing a new level of flexibility and convenience. The best news is that the Sedona Framework is open source software so it can be used free of charge. Visit www.sedonadev.org for more details.

Main Features of Sedona

• Processor and operating system independent

• Reuseable component library

• Program from Niagara Workbench Tool

Tridium have also been working with Jennic (now NXP) to develop a Sedona wireless solution. Jennic are a fabless semiconductor manufacturer who supply a variety of mesh wireless products. For the Sedona wireless version, the Sedona Framework component set is stored in ROM, enabling the maximum utilisation of the 128K RAM for the application configuration.

• Available on Jennic Microcontroller for small wireless applications
  

• Supports both wired and wireless on one chip set

• Wireless IPv6loWPAN Mesh standard

• Can support serial network connection and various I/O points
