kit includes complete TCP/IP stack support</b>
<br>Atmel present solution for networking all embedded applications. The
AVR microcontroller Embedded Internet starter kit and reference design
gives direct access to the Internet with Ethernet interface. The AVR Embedded
Internet starter kit is the first complete web server based on an 8-bit
microcontroller with integrated Flash memory and full TCP/IP support. It
can be used with right out of the box as a standalone embedded web server,
or as basis for custom applications interfacing to the Internet. The AVR
Embedded Internet starter kit is a complete system that displays web pages
on Internet and executes applications on top of the web server.
<br>The following protocols and features are supported:
<ul>
<li>
HTTP (HyperText Transfer Protocol) for displaying web pages </li>
<li>
FTP (File Transfer Protocol) server for remote download and update of files </li>
<li>
SMTP (Simple Mail Transfer Protocol) protocol for sending mail</li>
<li>
DHCP (Dynamic Host Configuration Protocol) for automatic configuration
of the web server from the network </li>
<li>
C o m p l e t e T C P / I P stack </li>
<li>
UDP (User Datagram Protocol) for direct IP data transmission</li>
<li>
ICMP (Internet Control Message Protocol) for PING response </li>
<li>
Low level interface drivers for CS8900 ethernet controller</li>
<li>
Ymodem protocol interface for local configuration and update of web pages</li>
<li>
File system for handling web pages and files in external serial flash memory </li>
</ul>
The software for the AVR embedded Internet starter kit is entirely written
in C-language, making it easy to modify the software to custom applications.
The included source code can be compiled directly and used in web server
applications or tailored to custom applications. The modular structure
of the code makes it easy to include the required functionality in the
final products. The AVR embedded web server starter kit includes all required
source code and documentation. </td>
<td ALIGN=LEFT VALIGN=TOP WIDTH="50%">The AVR embedded Internet starter
kit includes Windows PC software for configuring the web server. It also
includes web browser and diagnostics software. The AVR embedded Internet
starter kit is optimized for maximum flexibility. The scalable structure
of the AVR makes the migration between memory sizes painless.
<p>The AVR microcontroller family is the only microcontroller family that
gives full compatibility from 1Kbyte of flash memory to 128Kbyte of flash
memory with the same instruction set and development tools.
<p>The AVR embedded Internet starter kit is based on the mega103 AVR microcontroller
and a Crystal CS8900 ethernet controller. The design includes 32Kbyte RAM
and a 2Mbit (upgradable to 16Mbit) flash memory for storing web pages and
files. A serial port is included for configuring the web server, connecting
external modem, or displaying debug information. The AVR 8-bit microcontroller
is designed for low-power, high performance applications. AVR is optimized
for C-coding, which means faster and smaller applications than any other
8-bit microcontroller. Compared to 16-bit microcontrollers the AVR offers
the same performance and more flexibility at lower cost.
<p>In addition to the TCP/IP stack and low level interface more than 30Kbytes
of code is included in the AVR embedded web server starter kit. Several
examples of HTML files are also included to demonstrate how to control
external signals. The AVR microcontroller includes a high accuracy 10-bit
A/D converter, this gives very simple interface to sensor for measuring
temperature, pressure, voltage, or any other analog signal. Code examples
are included to demonstrate use of the A/D converter. All the source code
and the web page examples are included free of charge.
<p>The AVR embedded web server starter kit includes:
<ul>
<li>
AVR embedded web server board </li>
<li>
PC Serial cable</li>
<li>
Ethernet cables, crossed and normal</li>
<li>
AC power supply</li>
<li>
CD-ROM containing code libraries, Window PC software for configuration,
full documentation and complete schematic </li>
</ul>
