atmega8 webserver using enc28j60

[sherazi]

hi there!

i am starting this project , that contains the AVR and enc28j60... but i am not aware of what to do... i have searce eda board but couldnt find something for a complete newbie, so plz can u help me by explaining how can i start and how does it go....

where can i get the stack for tcp/ip for avr (i program in asmbly)

i need a complete tutorial.........and help.........................................

Did you read the book Embedded TCP/IP Lean?
I advice you to read it. Check amazon page https://www.amazon.com/TCP-IP-Lean-Servers-Embedded/dp/157820108X.
Also Microchip has free TCP/IP stack and good tutorials on how to use it with its products like Your ECNJ chip. Check this page **broken link removed**.

its ok ... now can you let me know how can i use this tcp ip stack in the pic... i have to include it in code or what? the thing i want is to measure humidity and temp from sensors and send it to ethernet

 

[amraldo]

It is a library, you have to compile it with your application.

 

[sherazi]

that means that i just have to include it as an include file and then write my program

 

[amraldo]

Include files and source files as well.
Did you write a C application before consisting of several files?
That's very similar.

what i want is that read temerature and humidity from sensors and make it available on internet.... using the webserver .. if i chose pic microcontroller and a enc28j60 how would i program it...

plz help me... its urgent

can u just give me points from the start pllllllllllllllzzzzzzzzzzzz

Man,
You should get a working project that has a webserver implemented using some PIC stuff, the ECNJXX and the controller that has a webserver.
Build this project as is.
Modify the webserver code to do whatever you want.
You can refer to the book I sent earlier or browse the internet for a similar project.

thats ok.. i have just got taht idea..

how would then i be sending data to etehernet... wht would be the algo

 

[amraldo]

You will have to add web page for example for your webserver
whenenver the page is requested, your webserver will run code that does what u want and send back the results to the webpage.

I'm making this project exactly ( measuring humidity and temperature) using PIC18F452 and ENC28J60, and i have the same problem, i dont know how to initialize the ENC program, just need somebody to instruct me step by step from the beginning.

p.s.: I have been searching for along time in this topic with no gain

Have a look to http://tuxgraphics.com/electronics/200611/embedded-webserver.shtml

It is easy to port the code that has been written for ATMega88 to ATMega8. You will need to do the following

- Remove clock prescaling two line of code in main.c.
- Change SPI pins (MISO, MOSI, SCK, SS) to match ATMega8 chip inside enc28j60.c
