Embedded Ethernet: Ethernut

The "Ethernut" project is an Open Source Project for building Embedded Ethernet Devices and is hosted on SourceForge.

Nut/OS Operating System

The main building blocks of the Ethernut project are a reference hardware design and the well documented Open Source Real Time Operating System Nut/OS.

It is free to use and distribute for both commercial and non-commercial applications under a BSD license.

Development

Applications are developed in the C programming language using the free AVR-GCC compiler toolchain on either Windows or Linux development hosts.

Nut/OS' architecture has been focused on portable standards. Developers with experience in C programming and TCP/IP applications for the PC will soon feel confident. Existing software can be adapted for Nut/OS with minimal effort.

The Nut/OS operating system offers a feature rich API including:

At the same time Nut/OS is a very lean OS which is well suited for microcontroller CPUs and their small memory footprint. Typically more than 100 KB program space and 20 KB data memory are available for your application. Nut/OS comes with several sample applications, including an embedded web server and a RS-232 to Ethernet gateway.
