Ethernet Comms

[wayne millard]

Hi Everybody,

Has someone got any example of two micros communicating with each other over a Ethernet network using ENC28J60.
I have tried using some of the examples and i think that the ENC28J60 is working because all the light are flashing when i do a IP scan but cant see any found IP that the PIC is set at. and good example of two passing data would be good.

Thanks,
Wayne Millard

Hi Wayne

I just started to do the same. Here is my hardware I like to use. I use FC8.
I have a little experience with the PIC32MZ2048EFG
Which pic or hardware do you use?

Hi Stefan,

Thanks for the reply how are you going with your project? have you got any examples of what you have done so far?
I have used some of flowcode examples which seem to initalise the ethernet chip ok because all the LEDS are working when connected to computer but i cant ping the chip it will not reply.

Hi Wayne
Just a little note. You can not connect the PIC directly to the computer with a network cable. You need a HUB or a cross cable.
I ran the Olimex board and included the demo program FC_ENC28J60_Example.fcfx.
It's not working. I have to look...

Hi Wayne

I found the problem. Just insert the portnumber (80) to the commands.

ping is working from my computer.

Hi Stefan,

Thanks for the replys i now have it responding to IP ping the problem was the SPI channel can not get it to work on channel 1 or 2 but will work on software channel. im now trying to workout how to send and receive data and the differant protocals that can be sent and received.
if you get some data sent and received i would love to see a example.

Thanks,
Wayne

Hi Wayne

I did a small change in the pointer and now I can acces the Pic with the Internet Explorer under Ip 192.168.1.90
and change to page2 ....
and with the TigerJython (Python) I have acces too.
TigerJython is free and you just copy the text in the program.

Now I found in FC8 the component: NetworkComms1
I think I gon on with this component.

regards

Stefan

http://jython.tobiaskohn.ch/download2.html

Code: Select all

import socket
 
host = "192.168.1.90"
port = 80

# Phase 1
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host , port))

# Phase 2
#request = "GET /py/welcome.html HTTP/1.1\r\nHost: " + host + "\r\n\r\n"
#request = "GET /page1" + host + "\r\n\r\n"
request = "GET /page2" 
s.sendall(request)

# Phase 4
reply = s.recv(4096)
print "\nReply:\n"
print reply
