ethernet using pic16f877 and enc28j60

[gabriel]

Hello:
I need to interface a PIC 16F877A to the internet using a ENC28j60, just to exchange short frames with a remote server (4-5 bytes), I don't have experience in this domain, can anyone help me and provides some useful links or an already made project?
Thanks in advance

In a Pic16F877 not all stack TCP / IP, you need a PIC with more memory.

Definately need an 18 series pic there are lots of ready made boards too just google but heres a little info

No way! The ENC28j60 TCP/IP stack will never fit ii a 16F device. I suggest you download the TCP/IP stack from microchip. Then you will know what kind of PIC device you should use.

Have a look in here:

http://www.ljcv.net/projects/mchptcp3.75/hardware.html

Good starting point here, and you find fairly detailed discription for a biginer.

It explains TCP/IP  with various PIC 18F and 24F using a ENC28j60, it is easy & have a go..

If you need i can guide and help you .I have completed full featured webserver using pic 18f452 with enc28j60 with mcc18 andwith  ccs compiler .If u need i can help with all details


Edit: Do not post contact details, if you have something to share, then share it.
as the salvation army say "to share is to care"

Can you share the working version over here?

thanks

It can be possible to use PIC16F with enc28j60 for UDP data transfer. If you can see pic18f452 and just udp then you find that it is possible for UDP... I done this for UDP data transfer for 8 bytes of packet...

I have SD card web server that is with pic24f and pic33F, Sd card is useing all htm file and that been process with pic24f

I disagree. The problem with 16F877 is flash memory space (8K). The TCP/IP stack from microchip uses ~12K (at least!). Unless you have done it and can share/prove it. Can you?

If you want to help, post your code here for everyone. No private share in this forum

SURE .i WILL COMPILE ALL DETALS AND POST HERE TO GIVE BENEFIT TO ALL MEMBERS.SUNDAY ONLY HOLIDAY FOR ME THAT DAY I COMPILE AND POST

Why the Shouting?

I was revisiting pages that I though was not in keeping with a forum.
You never got back to this topic, and spent the last ten years taking space here.
so your on a ten year mute.

quote  "The TCP/IP stack from microchip uses ~12K (at least!)."

which is true..but its a full version and contains a lot of code that may not be used.

a good book to have is "TCP/IP Lean : web servers fo embedded systems" by Jeremy Bentham.
this book shows how to run TCP/IP on a 16c76 and 877..and was done before the feature rich ENC28j60 became available..it also shows how to rom html for serving..

not sure if you can get a ebook version but its well worth searching for.

Something else you might want to look at is MikroC. It has a built in SPI Ethernet library for talking via an ENC28J60. They use an 18F4520 in their example code, but by avoiding the full microchip stack you may be able to massage this to work with the 16F877. Let us know how you go. I've a handful of sample ENC28J60's that I've been meaning to get around to using for a variety of projects

BTW: Is there any reason why you have to use the 16F877 and not an 18 series device?

[gabriel]

I just know the 16F877 very well and thought it could work with ENC28J60. Now I'm looking in the 18F series, mainly 18F452 or 18F4520.
About MikroC, I tried it once, I couldn't generate a COF file needed to debug with ISIS PROTEUS, is there any way to get it?
Thanks

I'm not sure about that Gabriel. I'd only just seen an advert in EPE the day before that so I was aware of the libraries and the examples that were available. I went to their website tonight and downloaded the examples to have a look for myself. They include samples for C, Pascal and Basic.

This inspired me to look at me the MikroBasic version I have installed on my workshop PC and, sure enough, there are examples for both 16F and 18F MCUs included. I did a very quick compile test of the example code with a 16F877a and generated no errors. I haven't tested this in either Proteus or on an actual test circuit however. The results thus far would seem encouraging though.

Depending on your language preference, this would seem an almost ideal solution for you. The examples on the website also include a sample circuit diagram which would be very easy to construct on a prototyping breadboard and requires only a handful of passive components.

Schematic: http://www.mikroe.com/pdf/serial_ethernet_schematic.pdf

(Interestingly, this schematic is missing a 74xxx series IC that was in the advert I saw. I think it may have been a bit shifter or some such thing. I don't have the article handy to view right now and I didn't pay enough attention when I saw it the first time around *blush*)

Examples: http://www.mikroe.com/en/download/

I've included the example header here for you to see. All the code is available included with MikroBasic. I don't have MikroC but I'm guessing they'd have similar code available for it.

' * V1.0 : first release
' * V1.1 : bad MIME type for / path request, changed to HTML instead of SCRIPT (thanks Srdjan !)
' *
' * description  :
' *      this code shows how to use the Spi_Ethernet mini library :
' *              the board will reply to ARP & ICMP echo requests
' *              the board will reply to UDP requests on any port :
' *                      returns the request in upper char with a header made of remote host IP & port number
' *              the board will reply to HTTP requests on port 80, GET method with pathnames :
' *                      /               will return the HTML main page
' *                      /s              will return board status as text string
' *                      /t0 ... /t7     will toggle RD0 to RD7 bit and return HTML main page
' *                      all other requests return also HTML main page
' *
' * target devices :
' *      any PIC with integrated SPI and more than 4 Kb ROM memory
' *      32 to 40 MHz clock is recommended to get from 8 to 10 Mhz SPI clock,
' *      otherwise PIC should be clocked by ENC clock output due to ENC silicon bug in SPI hardware
' *      if you try lower PIC clock speed, don't be surprised if the board hang or miss some requests !
'
' *
' * EP settings :
' *      RA2 & RA3 pots jumper : closed
' *      PORTB : pull-down
' *      PORTC : pull-down
' *      BUTTONS : pull-up

' *      RC0 : !RESET    to ENC reset input pin
' *      RC1 : !CS       to ENC chip select input pin
' *      the ENC28J60 SPI bus CLK, SO, SI must be connected to the corresponding SPI pins of the PIC
' *      the INT and WOL signals from the ENC are not used
' *
' * Test configuration:
'     MCU:             PIC16F877A
'     Dev.Board:       EasyPIC5
'     Oscillator:      HS, 08.000MHz
'     Ext. Modules:    mE Serial Ethernet board
'     SW:              mikroBasic v7.1
' * NOTES:
' 	  - Since the ENC28J60 doesn't support auto-negotiation, full-duplex mode is
'       not compatible with most switches/routers.  If a dedicated network is used
'       where the duplex of the remote node can be manually configured, you may
'       change this configuration.  Otherwise, half duplex should always be used.
'     - External power supply should be used due to Serial Ethernet Board power consumption.

Hope this helps you out on your journey. If I learn anything more along my travels I'll be sure to let you know. This has definately sparked up my interest in getting some web-based interfaces happening for a couple of my older projects

Edit:
Here is the output from the compiler. As you can see, there's still room left for adding your own code or modifying the example code.

Hi,

Here is a trick to get the pdf and save it on your PC (and works for other Books found on this server).

Use this link: http://www.esnips.com/displayimage.php?pid=1942883 don't click anywhere !!!

Wait until the web page show the first page of the book (TCP/IP LEAN...) and show 1 / 534 pages.
At the right of 1/ 534 you have small icones for zooming and an arrow to open in a other windows, click on this icone (the small arrow).
Again please wait... once the document loaded, on the top of the document, just under "file_serve.php" you have "File Display Help" for your language, example in French "Fichier Affichage Aide".
Click on File, then in the menu, click on "Download Original Ctrl+S" and save the pdf file.

I Hope this tricks will help you.

Best regards.

Sorry by the question, but why do you want to use that obsolete pic? Or do you have already some board that you want to use?

See this links:
cost for 10 units: 5.7 U$S
http://www.digikey.com/product-detail/en/PIC16F877A-I%2FPT/PIC16F877A-I%2FPT-ND/480769
cost for 10 units: 6.3 U$S
http://www.digikey.com/product-detail/en/PIC32MX664F128H-I%2FPT/PIC32MX664F128H-I%2FPT-ND/2601589

I always select the best pic that I can have for the best cost (but that is only my opinion). I'm not really a fan of the PIC32MX because the best for me is PIC24HJ

I have the PIC32MX working with the LAN8720 10/100 Mbps ethernet PHY, I know it isn't the same (and require a more advanced PCB), but you have a lot more performance for only a few dollars more.

If you want a REALLY cost sensitive application, I recommend you the pic PIC18F67J60 (or some of this family, there are others with more flash memory). This one are very cheap and already has the MAC/PHY incorporated! only need the ETH jack with magnetics.

Ask if you need some information!
