В ответ на: А не встречал ли кто нибудь в И-нете исходников WEB-сервера? отправлено Altair 08 декабря 2001 г. 11:57

У меня есть pack = 8M нарыл на электроде. Сегодня хотел положить куда-нибудь, да вот inet подкачал :(


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.
The following protocols and features are supported:

HTTP (HyperText Transfer Protocol) for displaying web pages
FTP (File Transfer Protocol) server for remote download and update of files
SMTP (Simple Mail Transfer Protocol) protocol for sending mail
DHCP (Dynamic Host Configuration Protocol) for automatic configuration
of the web server from the network
C o m p l e t e T C P / I P stack
UDP (User Datagram Protocol) for direct IP data transmission
ICMP (Internet Control Message Protocol) for PING response
Low level interface drivers for CS8900 ethernet controller
Ymodem protocol interface for local configuration and update of web pages
File system for handling web pages and files in external serial flash memory

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.

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.

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.

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.

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.

The AVR embedded web server starter kit includes:

AVR embedded web server board
PC Serial cable
AC power supply
CD-ROM containing code libraries, Window PC software for configuration
full documentation and complete schematic
