uIP 1.0

uIP TCP/IP stack provide TCP/IP connectivity to tiny embedded 8-bit microcontrollers.
uIP TCP/IP stack provide TCP/IP connectivity to tiny embedded 8-bit microcontrollers, with maintained interoperability and RFC standards compliance.

uIP is an implementation of the TCP/IP protocol stack intended for small 8-bit and 16-bit microcontrollers.

uIP project provides the necessary protocols for Internet communication, with a very small code footprint and RAM requirements - the uIP code size is on the order of a few kilobytes and RAM usage is on the order of a few hundred bytes.

uIP is open source software written in the C programming language and the documentation and source code is free to use and distribute for both commercial and non-commercial use as long as proper credit is given (the full BSD-style license is here). It has been ported a wide range of 8-bit microcontrollers and is used in a large number of embedded products and projects (see the Links page for a few examples).

Here are some key features of "uIP":

Well documented and well commented source code - nearly every other code line is a comment.
Very small code size.
Very low RAM usage, configurable at compile time.
ARP, SLIP, IP, UDP, ICMP (ping) and TCP protocols.
Includes a set of example applications: web server, web client, e-mail sender (SMTP client), Telnet server, DNS hostname resolver.
Any number of concurrently active TCP connections, maxium amount configurable at compile time.
Any number of passively listening (server) TCP connections, maximum amount configurable at compile time.
Free for both commercial and non-commercial use.
RFC compliant TCP and IP protocol implementations, including flow control, fragment reassembly and retransmission time-out estimation.

What's New in This Release:

A new socket-like API, protosockets, was added.
uIP now has rudimentary IPv6 support.
A DHCP client was added and the Web server was rewritten with protosockets.
Device driver structure was simplified.
Many bugfixes were made in the TCP code.
A uIP mailing list was started.
