RIOT-OS/RIOT
RIOT
RIOT is a real-time operating system designed for resource-constrained microcontrollers. It provides a kernel for managing hardware peripherals, memory, and multitasking on embedded devices, featuring a microcontroller hardware abstraction layer to unify hardware access across different chipsets.
The system employs a preemptive tickless task scheduler with priority-based execution to maximize energy efficiency in battery-powered hardware. It also includes an embedded security framework consisting of cryptographic APIs and secure transport protocols to facilitate authenticated over-the-air firmware updates.
The project further implements a modular network stack supporting IPv6, IPv4, and Ethernet for device connectivity. It covers peripheral hardware control for sensors and actuators, flexible device memory management, and the execution of portable binaries and scripts through specialized runtimes.
