Hello everyone,
I am just trying to dig into the pic ethernet area. I have some very basic understanding of ENC28J60 ethernet controller and I've read AN833 (The Microchip TCP/IP Stack). I've downloaded the legacy MLA files from microchip (TCP/IP stack v5.42.08) and started trying a few things. I am using MPLAB 8.86 and Hitech C 18.
Till now...only frustration.
I really can't even compile the Demo App, I'm struglling to find the way out, hopefully today and I can't find any tutorial on the net regarding PIC ethernet. On the other hand, I can find a lot of material for arduino and this time, it is a little tempting to switch to AVR (please don't let me)
My goal for now is just to blink a led through http.
I really need some guidance so If anyone has experience on the PIC ethernet , please help me out.

 

I also plan to create an project with ENC28J60. I have found a project which is a bridge between PC computer and ZigBee wireless network, however, link with PC is established by USB2.0.
http://www.mbstudent.com/microcontrollers-distributed-system-of-data-collection.html

I plan to create something similar, nevertheless, I would like to make a bridge through Ethernet instead USB.

 

If I remember correctly, the Wiznet devices are very similar to the ENC28J60, so you may also get some insight from looking at projects using those.

Additionally, here are some references you can peruse:

• AN1120(PDF)
• Project trying to control a robot with PIC and ENC28J60
• ATMega and ENC38J60
• Webserver using ENC28J60 and ATMega (useful for seeing how to use the chip)
• Don't forget the datasheet!
  

 

I've been struggling all day to get the demo app to compile. I only get errors. Has anyone tried it before? Any help please will be welcomed

What errors are you getting? Those usually indicate what is wrong...

 

No progress till now
I've download TCPIP stack 2.2 and tried again. This is what I get:

BUILD FAILED

 

Grrrrrr.......
After spending two days just trying to figure out the problem, guess what, I didn't....
I managed to get things to work by downloading the TCP/IP Stack v4.02 and with language tool versions: MPASMWIN.exe v5.46, mplink.exe v4.45, mcc18.exe v3.44, mplib.exe v4.45, everything worked.
I did nothing fancy this time. Just fixed the include paths and when I pressed ctr+F10, everything compiled properly.
I don't know what to say....
At least it works now!

 

Looks like the original problem was in the MCHPStack2.20. The code might have been OK. I've had a lot of difficulty not being able to compile perfectly good code on PIC compilers.

Well, I just realized that if you plan to work with a small 16F or 18F then probably v2.2 is your only solution since it needs just about 12k of mem. Current version needs more than 60k so probably not a good choice more mid range mcus!

 

@Brownout
I am still missing a good tutorial about how to move further. Since you have already worked with TCPIP Stack, please enlighten me.

 

What kind of help do you need? So if I'm right, you have the stack compiled and running, and you just need some code, right? Ok well, I never wrote any code for your particular stack; however, I wrote a simple socket server for a Windows computer, and made a little blog entry for testing it. It won't run for you without some edits, at least you'll need a different #include directive. Anyway, here is the link. Let me know if this helps.
