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 supports most low-power IoT devices and microcontroller architectures (32-bit, 16-bit, 8-bit). RIOT aims to implement all relevant open standards supporting an Internet of Things that is connected, secure, durable & privacy-friendly.
Features:
RIOT is Developer Friendly
- 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, ...)
