TinyOS is an open source, BSD-licensed operating system designed for low-power wireless devices, such as those used in sensor networks, ubiquitous computing, personal area networks, smart buildings, and smart meters.

  • TinyProd

The main Tinyos-Main tree has seen less activity over the years. That doesn't mean TinyOS is dead, rather most new work has been concentrated on the tinyprod repository. See tinyprod/prod and its working development repository tp-freeforall/prod

  • Make 3

The main TinyOS trees have been converted to using the new Make3 build system. See the (Make Version 3) section below.

TinyOS Wiki

Much information about how to setup and use TinyOS can be found on the wiki. It is also editable by the community if you have information to add or update.

About tinyos-main

Long ago (well not that long ago), in a galaxy not too distant, tinyos development was hosted on Google Code as a subversion repository. This repository was writeable by a select group of core developers.

TinyOS development has moved to a fully distributed model to encourage more participation by switching to the git distributed version control system.

The Github tinyos-main repository will still be writeable by those same core developers. Pull requests are welcome and will be reviewed by the core developer most familiar with the relevant code.

Repo Structure

Currently there is a single mainline, master. gh:tinyos/tinyos-main(master). This is equivalent to the tip of the svn trunk.

Branches are very inexpensive and are encouraged for any significant development. Typically, a feature will be implemented on a topic branch, ie. -int. where stands for integration.

For the immediate future, branching should be done in private user repositories until the community gets used to how they work.

The general form for a repository/branch reference is: <github_context>/(branch) ie. gh:tinyos/tinyos-main(master) is the master branch in the tinyos/tinyos-main repository. Note that github repositories have a specific default branch controlled by github repository settings. gh:tinyos/tinyos-main refers to the repository but if that repository is pulled it will reference the default branch.

Local repositories are referenced using local(branch).

(Make Version 3)

TinyOS development repositories (tinyos/tinyos-main, tinyprod/prod) use the Version 3 make build system (issue #190). (see below).

Version 3 Make system and tinyos-tools

The TinyOS make system has been upgraded to version 3. This brings many new improvements (see support/make/ for details) but also requires the tools to be rebuilt. To use TinyOS make version 3:

cd tools
sudo make install

alternatively you can use the tinyos-tools-devel package from repos/debian. See the Readme at the top level ( You need to modify /etc/apt/sources.list.d/tinyprod-debian.list. Change "squeeze" to "wheezy".

sudo -s
apt-get update
apt-get purge tinyos-tools
apt-get install tinyos-tools-devel
