The friendly Operating System for IoT!


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
  • UDP
  • 6LoWPAN
  • NHDP



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


There is a shellscript in RIOT/dist/tools/tapsetup called tapsetup 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:

./dist/tools/tapsetup/tapsetup [-c [<count>]]


To contribute something to RIOT, please refer to the development procedures and read all notes for best practice.
