inteface PIC18 with TCP/IP

[venod_08]

i'm doing a final year project regarding zigbee wireless microcontroller network.

i would like to know how can i interaface a microcontroller with TCP/IP.

pls help. tq.

microchip has a tcp/ip stack that is free i think.they also have a zigbee stack, a zigbee tranceiver, and an ethernet chip.

Speaking of TCP/IP ...has anyone done any work on publishing a web page from an MCU device? Like how printers and Routers have their own home page etc?

 

[Wilksey]

I have with the Microchip TCP/IP example, I have created other pages etc, is that what you meant?

 

[Mosaic]

Um, ...I'd like to make a device that can publish it's own page and respond to a ping when queried via a TCP/IP address.

Specifically I want to do some autonomous irrigation and motion sensing for praedial larceny in farmers fields. the MCU running the sensors would publish a web page that carries data on the various sensors and perhaps even crack off an e-mail alert when necessary.

 

[Wilksey]

Ah I see.

Well, you can implement the ICMP server as part of the stack, so theres your PING, you will have to allow your router to do the necessaries.

The default MCHIP sample page includes this, it uses AJAX to get real time feedback from a POT. It even comes with an SMTP example.

Have you looked at the stack from Microchip at all?

may i know the model of the PIC that has ethernet stack ?? i can't seem to find....

pls help..

The 18F67J90 has Ethernet hardware built in, you just need the magnetics and a handful of passive parts.

 

[Wilksey]

The one I use is the 18F97J60

 

[blueroomelectronics]

Oops, I stand corrected.

 

[Wilksey]

Only a number swap Bill Confused the hell out of me before I started using it!

 

[venod_08]

Thx a lot.. i found one but it is PIC18F67J60...

is it similar?

 

[blueroomelectronics]

Yep that's one, there are several, some have more I/O and or memory.

 

[Wilksey]

That is a "lighter" version of the 97J60, I think the 97J60 is the top one in the 18F series isn't it? It's the one I always use.

 

[blueroomelectronics]

All nice PICs and yes the 97J60 has got it all.

Did that with a Rabbit2000 TCP/IP kit. TCP/IP came with the libraries, so I didn't need to write anything except modify the example HTML page. The board died before I got very far, and I didn't want to spend another $199 for a new one.

 

[blueroomelectronics]

The Rabbit2000 was pretty neat, I've got one around here somewhere. I recall it's based on the Z80, but it was not an all in one IC like the PIC18F97J60.

 

[Mosaic]

I guess I start with the data sheett....anyone has a link to a sample code?

 

[venod_08]

anyone do have a schematic for this pic to be connected with the zigbee and also the RJ-45 connector?

it would be a great help.. i can't seem to find...

Sparkfun has an Ethernet PIC with schematic, the XBee S2 (ZigBee) would simply be connected to the UART pins.
