The friendly Operating System for IoT!
FEATURES
RIOT OS is an operating system for Internet of Things (IoT) devices. It is based on a microkernel and designed for
- energy efficiency
- hardware independent development
- a high degree of modularity
Its features comprise
- a preemptive, tickless scheduler with priorities
- flexible memory management
- high resolution timers
- virtual, long-term timers
- the native port allows to run RIOT as-is on Linux, BSD, and MacOS. Multiple instances of RIOT running on a single machine can also be interconnected via a simple virtual Ethernet bridge
- Wiselib support (C++ algorithm library, including routing, clustering, timesync, localization, security and more algorithms)
- IPv6
- TCP and UDP
- 6LoWPAN
- RPL
GETTING STARTED
- You want to start the RIOT? Just follow our Getting started documentation
- The RIOT API itself can be built from the code using doxygen. The latest version is uploaded daily to http://riot-os.org/api.
USING THE NATIVE PORT WITH NETWORKING
If you compile RIOT for the native cpu and include the nativenet module, you can specify a network interface like this: PORT=tap0 make term
SETTING UP A TAP NETWORK
There is a shellscript in RIOT/cpu/native called tapsetup.sh which you can use to create a network of tap interfaces.
USAGE To create a bridge and two (or count at your option) tap interfaces: ./tapsetup.sh create [count]
EXAMPLE APPLICATIONS
In the examples directory you can find some example applications. The default application demonstrates all available features for the current platform.
For example, you can use it to the test the native networking by running two instances: make term PORT=tap0 and make term PORT=tap1. Now configure two different addresses for both RIOT instances by typing addr 1 and addr 2 respectively and send a text message from one "node" to another by typing txtsnd 2 hello on the first "node".
CONTRIBUTE
To contribute something to RIOT, please refer to the development procedures and read all notes for best practice.
