"If your IoT device cannot run Linux, then run RIOT!"
- RIOT requires only a few kB of RAM/ROM, and small CPU
- With RIOT, code once & run heterogeneous IoT hardware
– 8bit hardware (e.g. AVR) – 16bit hardware (e.g. MSP430) – 32bit hardware (e.g. ARM Cortex-M)
RIOT: Positioning

RIOT: Fact sheet
- µ-kernel-like architecture(for robustness)
- Modular design (for adaptivity)
- Tickless scheduler (for energy efficiency)
- Deterministic O(1) scheduling (for real-time)
- Low latency interrupt handling (for reactivity)
- Preemptive multi-threading & powerful IPC
- Efficient hardware abstraction
- Full featured, extendable network-stacks

RIOT: IoT development made easy
- Open source, community-driven
- Write your code in ANSI-C or C++
- Compliant to the most widely used POSIX
features such as pthreads and sockets
- No IoT hardware needed for debugging
– Run & debug RIOT as native process in Linux

RIOT: Built to connect
- RIOT supports several network stacks
- Open-access protocol specs by the IETF/IRTF
- e.g. 6LoWPAN, IPv6, CoAP

RIOT Origins
History
- 2008 – Project roots:
The kernel was started as part of a research project
- 2010 – Towards the IoT:
Implementation of 6LoWPAN and RPL was initiated
- 2013 – RIOT goes public:
Branding of RIOT started, source code moved to Github Founding institutions
