## What it is
uIP is a very small TCP/IP stack implementation written in C by Adam Dunkels, designed for resource-constrained embedded systems. This repository holds the historical sources of the original uIP 1.0 code.

## Use cases
- add TCP/IP networking to a microcontroller project
- study a minimal TCP/IP stack implementation
- run a tiny TCP/IP stack on 8-bit embedded hardware
- learn how embedded networking protocols work
- port a lightweight IP stack to a constrained device

## When to choose
- you need an extremely small TCP/IP stack for a resource-constrained microcontroller
- you want to study the historical origins of embedded networking (precursor to Contiki/lwIP era)
- you're maintaining legacy embedded code that already uses uIP

## When to avoid
- you need a maintained, modern TCP/IP stack - use lwIP instead
- you need IPv6, TLS, or modern protocol features
- you want an actively supported project with a clear license

## Facets
- artifact type: library
- maturity: abandoned
- function: networking
- domain: embedded-systems, networking, operating-systems
- platform: c, embedded, cross-platform
- tags: tcp-ip-stack, embedded-networking, iot, historical, microcontroller, linux
