The friendly Operating System for the Internet of Things. RIOT powers the Internet of Things like Linux powers the Internet. RIOT is a free, open source operating system developed by a grassroots community gathering companies, academia, and hobbyists, distributed all around the world. RIOT implements all relevant open standards supporting an Internet of Things that is connected, secure, durable, and privacy-friendly.

RIOT is a developer friendly program like you are used to. Do not waste time with complex or new environments. • Standard programming in C or C++ • Standard tools such as gcc, gdb, valgrind • Minimized hardware dependent code • Zero learning curve for embedded programming • Code once, run on 8-bit platforms (e.g. Arduino Mega 2560), 16-bit platforms (e.g. MSP430), and on 32-bit platforms (e.g. ARM) • Partial POSIX compliance. Towards full POSIX compliance. • Develop under Linux or Mac OS using the native port, deploy on embedded device RIOT is Resource Friendly Benefit from a microkernel architecture and a tickless scheduler on very lightweight devices. • Robustness & code-footprint flexibility • Enabling maximum energy-efficiency • Real-time capability due to ultra-low interrupt latency (~50 clock cycles) and priority-based scheduling • Multi-threading with ultra-low threading overhead (<25 bytes per thread) RIOT is IoT Friendly Make your applications ready for the smaller things in the Internet with common system support. • 6LoWPAN, IPv6, RPL, and UDP • CoAP and CBOR • Static and dynamic memory allocation • High resolution and long-term timers • Tools and utilities (System shell, SHA-256, Bloom filters, ...)
