uIP

uIP is a super cool TCP/IP stack that gives tiny embedded 8-bit microcontrollers the ability to connect to the internet. It keeps everything running smoothly by sticking to those important RFC standards.

What is uIP?

So, uIP is basically a way to implement the TCP/IP protocol stack. It's designed specifically for small 8-bit and 16-bit microcontrollers. If you're into embedded systems, this could be just what you need!

Why Choose uIP?

This project offers all the necessary protocols for internet communication, but here's the kicker: it has a tiny code footprint and doesn't hog RAM. The size of uIP's code is just a few kilobytes, and it only needs a few hundred bytes of RAM to run smoothly!

Open Source Goodness

If you're someone who loves open source software, you'll be happy to know that uIP is written in C and it's free! You can use and share it as long as you give credit where it's due. Check out the full BSD-style license here. It's been adapted for a wide range of 8-bit microcontrollers and shows up in lots of embedded products out there.

Key Features of uIP

• Well-documented source code: Almost every line has comments to help you understand.


• Tiny code size: Perfect for small devices!


• Low RAM usage: You can even configure this at compile time.


• Protocols included: ARP, SLIP, IP, UDP, ICMP (ping), and TCP.


• Example applications: Comes with a web server, web client, email sender (SMTP client), Telnet server, DNS resolver - all ready to go!


• No limits on connections: You can have any number of active TCP connections or listening ones; maximums are set during compile time.


• Total freedom: Free for both commercial and non-commercial use.


• Proudly RFC compliant: This includes flow control and fragmentation handling.

What's New in This Release?

• A new socket-like API called protosockets was introduced.


• The latest version supports basic IPv6 functionality!


• A DHCP client has been added along with an updated web server using protosockets.


• The device driver structure has been simplified for easier use.


• A bunch of bug fixes were made in the TCP code—always good news!


• A mailing list for uIP enthusiasts has been started too!
