How can I Network using a microcontroller

Not only will you need to write the packet driver, but you'll have to write the TCP/IP stack, too.

If you ask for "help to write the driver", then you probably need to hire a programmer. If you have *specific* questions, ask post them to the newsgroups.

Rabbit makes an 8051 development board complete with 10 base-t ethernet and includes a TCPIP stack with source - I think.

Check out Digikey

I have wondered about the same thing; or minimum effort to add TCP/IP...

HAs anyone experience with Wiznet modules, like the IIM7010A ???

Get the book "TCP/IP Lean, 2nd Ed", by Jeremy Bentham, CMP Books. Nice discussion of how to implement a really small TCP/IP stack. He doesn't provide an 8051 implementation, but his C code will work on a PIC.

You'll need a tcp-ip stack. You might consider using embedded Linux or uCLinux.

You can also have a look at

The PICDEM.net demo board from Microchip and TCP/IP Lean go hand in hand. There is a also an Atmel solution that my former colleague did. If i had to implement it, i'd probably purchase a picdem.net board and try to reuse the code.

or eCos.

I found a one-chip solution that looks like an exact fit for what you want. Look at

The DSC80C400 is an 8051-based microcontroller that has a MAC peripheral built in the chip. It also comes with the TINI TCP/IP stack in ROM. I don't know how to use it though, but for an 8bit chip, this is something i'm definitely going to be looking into now.

Normally, yes, you would have to but recent components like the W3100A do much of the toil in h/w. An 8051 is severly underpowered, and under-RAM'ed, to handle even low speed ethernet let alone multiple sockets.

This can be a very big effort, especially the TCP stack.

See

Google on 8051 and one of these controllers: NE2000, RTL8019AS, CS8900A,

Best, look at one of these turnkey solutions that translate a serial interface to TCP:

On an 8051 ? You must be kidding :-)

No, IMHO Rabbit uses their own CPU's which resemble more a Z80 than an

While I havent used this part so far, this might be a good candidate for what you want since it includes a MAC and a complete TCP/IP stack. See:

I'm not sure if we're talking the same thing, if you want netowrking like TCP-IP or you just want the processors to talk to each other. If the later is true the 9 bit serial mode works great for that.

The original point was an 8051-web server. Linux will not run on an 8051.

There is a limited TCP/IP stack called emBetter for HC12, but AFAIK it is mostly in ANSI-C.

Hi Omid.

I develope a fantastic IPC@CHIP Beck board based on Beck SC12 Chip (186 with Ethernet/CF socket/two serial port, I/O, Sja1000 CAN controller ecc)

You can debug and program chip with free Beck Tools (Borland C++ 5.2 with special Turbo debugger) with 10mbit ethernet connection

You can develope web server, Tcp remote client/server control, Ftp PPP Email connection ecc..
