15,627View on GitHubZephyr is a real-time operating system and cross-platform embedded framework designed for resource-constrained hardware architectures. It provides an embedded kernel that manages memory, power consumption, and hardware peripherals across multiple microcontroller architectures. The project utilizes a hardware abstraction layer to decouple high-level kernel services from physical hardware through standardized driver interfaces. It employs a device tree hardware description format and a hierarchical configuration system to optimize binaries and feature sets for specific hardware constraints. Th
