Micro Web Server

Welcome to an 8-bit microcontroller web server!

Location
This embedded server is situated in Christchurch, New Zealand

Details
The server is based on the Ethernut 1.3f hardware, using the popular Atmel ATmega 128 microcontroller, running the Nut/OS. The actual hardware can come in many different flavours, but the server you are connected to right now is a Web Tiger.

Microcontroller	ATMega128	With 128k ROM and 32k external SRAM
Network Chip	RTL8019AS	Memory mapped network controller
TCP/IP Stack	Nut/Net	Nut/OS for the Win32 Environment
File System	FAT16	Roland's Card Reader Version 20060901
C Compiler	WinAVR	AVR-GCC for Win32, GNU GCC compiler

The software is written in C, and is a mixture of code blocks found on the Internet and by myself. Web pages are stored on a multi-media card and accessed with a modified version of Roland Riegel's SD/MMC FAT16 code. FTP has been implemented for easy web site maintenance and a hardware Real Time Clock (RTC) has been added to enhance the Ethernut 1.3 based hardware. To complete the system, a 4x20 Liquid Crystal Display (LCD) has been attached for displaying status, date, time and any msg's that visitors might leave behind.

Fun Stuff

Leave a message on the attached LCD :-)
A good example of using the http form method to send data back to the host.

The Liquid Crystal Display is a standard HD44780 based, 4 x 20 characters module.

Nut/OS Samples and Demo's

What are they?
The Nut/OS download comes with some sample applications. The http.c project includes code to test the various capabilities of the system.

Flash demo	ASP demo	Form demo	Timer list
Server side inc demo	Parameter demo	Thread list	Socket list

The lists are the most useful ones. The socket list displays what connections are open/closed, and the thread list lets you keep an eye on stack memory usage.
