RIOT OS: A tiny OS for embedded systems
Initially developed by Freie Universität Berlin (FU Berlin), INRIA institute and HAW Hamburg, Riot OS has evolved over the years into a very competent alternative to TinyOS, Contiki etc. and now supports application programming with programming languages such as C and C++, and provides full multithreading and real-time capabilities. RIOT can run on 8-bit, 16-bit and 32-bit ARM Cortex processors.RIOT is opensource, has its source code published on GitHub, and is based on a microkernel architecture (the bare minimum software required to implement an operating system).
