Embedded Technology Overview

I. TuyaOS Development Framework

1. System Architecture and Core Capabilities

TuyaOS is a self-developed embedded operating system written in pure C, spanning RTOS/Linux/Non-OS. It provides a five-layer architecture (Kernel/Abstraction Layer/Library/Service/Application), adapts to the full range of 8-bit to 64-bit chips, and delivers minimal resource footprint, ultra-low power consumption, ultra-fast networking, full protocol coverage, and high security.
