ENC28J60 and PIC24 compatibility

Franck26 · Joined: 29 Dec 2007 Posts: 122 Location: Ireland

Hello,

I would like to use the ENC28J60 connected to a PIC24 to make a simple TCP/IP server.

Do you know if the CCS ENC28J60 driver is compatible with the PIC24?

Does anybody has already implemented a server using the ENC28J60 and a PIC24? Is there any problems?

Thanks,
Franck.

It's an SPI based device. I imagine it would work just fine with the PIC24 family.

It's a 3.3V device... and the PIC24's are 3.3V as well.

Sounds like a match made in heaven. (or as MCHP would have you believe!)

Hahaha, good luck!

The question is really, do the CCS TCP/IP drivers work with the PCD
compiler ? Have they been tested with it ? Also, there are two
sets of drivers. One is shipped as part of the CCS TCP/IP package,
which is downloadable on the compiler update page with a separate
button. The other drivers are shipped with each compiler update.
These two sets are not necessarily in sync. Again, the question is,
do either of these sets of drivers work with the PCD compiler, and
specifically with the ENC28J60 ?

If no one has a definitive answer on that, you need to email CCS support and ask them.

That's a good question -- I see Microchip has a PICtail module for the Explorer 16, which I have... (with a 24 series IC on it)

I think I might order me one so I can test it out since I think I foresee a use for such a device in a project I'm currently working on.

EDIT: I ordered the PICtail plug-in for my explorer16 to try this out. I should have the module on thursday.

Hi,
Thanks for your answer and sorry for the lateness of this reply (was traveling...).

@bkamen:
You are right, I don't think that I'll have any hardware issue to connect the ENC28J60 to a PIC24.
Please, let me know if you can make your PICtail working with the CCS librairy Smile

.

@PCM programmer:
In the TCP.c header:

I just got my PICtail for the explorer16 today... I'll get to it tomorrow or saturday (work work work!)

:D

I had never realized how cheap are those microchip demo kit...
I'm going to purchase one too Very Happy

I'm almost done getting an HTTP server running on the board (I hope at least) but ran into a weird PCD issue which I have submitted to CCS.

The program halts because of a function called that isn't declared when it for sure as heck is.

PCH compiles just fine. PCD does not.. so I emailed them the project to take a look.

I need this stack running because of another project I'm working on that might need to jump to PIC24H because of PIC18 performance issues.

More when I have it.

OK, I can compile successfully... but it only runs for a short moment and then resets. (debugger regardless)

So I have more chasing down to do.

Weee...

Have you been able to connect the module via Ethernet during this short moment?
if it is the case, that's already great Razz

!!!

Good luck, and keep us informed!!!

Franck.

The 28J60 PICtail module initializes (the link/data LED's come to life) -- but the firmware resets before I can do anything else. I'm going to be spending some of today chasing it down.

So I would have to say that the module works... something somewhere is busted and I need to find it.

Hahah, it's funny you mention that--- I've been doing just that.

Did you try to use the address error trap to locate resets caused by data alignment errors?

The other "popular" reason for PIC24 resets is PCD's too small default stack assignment. http://www.ccsinfo.com/forum/viewtopic.php?t=40083
