uIP For Linux

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.
