Embedded Web Server

You lost me on most of your post,(I'm a failed 8051 git) but have a look at the Xport from

I doubt it. I really doubt you can get uCLinux running on a custom platform without spending several hours on the project. I would guess you'll have to spend a minimum of week or two to get uCLinux running on a custom target.

Of course, the same is going to be true for any OS capable of running a web server. Still, you might want to take a look at more lightweight options such as eCos

Atmel do it on an 8051......!!! They also have a HW TCP/IP stack as well if the FREE software one does not do what you need...

IT depends how much you want to do. There are quite a few systems (like EMIT) that do not need an OS let alone one as large as Linux.

What sort of throughput do you require? If low throughput is ok (as it is on many embedded systems) then there are a lot of low cost options:

etc. etc.

Here is an http embedded server requiring only a socket library. The source code is provided. You don't need any file system. The test code runs on linux but it should be easy to port it to any rtos that has a tcp ip stack and that supports sockets.

You might also take a look at the ez80Acclaim! from ZILOG. With their ZTP 1.5.0 they provide a nice TCP/IP stack with e real time kernel. A development kit (EZ80F910100KIT) is offered at a reasonable price of $99 (DigyKey, Mouser, ...). The core module( eZ80F915005MOD) with controller + FLASH, RAM and PHY measures only 4,5 x 5 cm, so it might be small enough to meet your requirements.

Take a look at our coldfire solutions.

The lowest cost is the MOD5270

You can start with our modules and if the $59/1K price is too high for production then you can license the IP and build it yourself.

For a completly independant review take a look at the recent electronic design article.

As fine board as this is,

is a few bucks cheaper. Only problem is limited number of I/O.

But has anybody experience with the ME? How fast can the ethernet (and total I/O) speed got? I need almost 3 Mbit/s.

Are you augmenting an existing design, where you just need to add the web / telnet front-end? If so, the Lantronix XPort and Digi ME are a turnkey platform built into an RJ-45 jack - MCU, RAM, Flash, MAC, PHY, crystal, etc. At about $50 ea, there is no smaller solution.

Add one to your board and use either serial or GPIO from the jack to your main MCU. The units can be scripted to front-end a CLI or a basic serial command interface.

However, if you're looking to use this Ethernet MCU as your primary processor, then others are probably better suited.

But consider the total cost involved, including development cost - you may find that a smaller, cheaper primary MCU with one of the Digi or Lantronix is cheaper / simpler overall.
