HowieXue/Linux_Gateway-ioT
LInux 平台下物联网网关（多线程实现），嵌入式项目
A multi-threaded IoT gateway implementation in C targeting embedded Linux, specifically the Samsung S3C6410 SoC. It handles protocol translation, serial communication, SQLite persistence, camera input, and a handful of peripheral drivers. This is a student or hobbyist project for learning embedded Linux concurrency, not something you'd drop into production.
The threading decomposition is sensible — each peripheral or protocol concern gets its own pthread file, which keeps the concurrency model readable. SQLite is a reasonable choice for local persistence on constrained hardware where a full RDBMS is out of the question. The project covers a realistic slice of embedded gateway concerns: UART, camera, heartbeat, SMS, and protocol translation all wired together, which makes it useful as a reference for how these pieces connect.
Last commit was April 2019 and targets a specific SoC (6410) with pre-built binaries checked into the repo — not portable, and those binaries are a security liability if anyone actually runs them. There is no synchronization strategy visible from the file names: 14 pthreads sharing global state with a single sem.h is a race condition waiting to happen, and there is no documentation of the locking model. The README is two sentences in Chinese with no build instructions, no architecture diagram, and no protocol documentation. This is not a library or framework — it is a single-target homework project with no abstraction layer.
