Title: ethernet using pic16f877 and enc28j60 Post by: gabriel on February 22, 2009, 06:58:37 18:58 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 Gabriel Title: Re: ethernet using pic16f877 and enc28j60 Post by: bender on February 22, 2009, 07:22:31 19:22 In a Pic16F877 not all stack TCP / IP, you need a PIC with more memory.

Thanks in advance Gabriel 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. http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=2680&dDocName=en537041 Title: Re: ethernet using pic16f877 and enc28j60 Post by: puta on February 23, 2009, 01:05:23 01:05 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..

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?

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.

A greetings Title: Re: ethernet using pic16f877 and enc28j60 Post by: sherm on March 06, 2009, 05:30:57 05:30 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? Title: Re: ethernet using pic16f877 and enc28j60 Post by: gabriel on March 06, 2009, 05:20:43 17:20 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 Title: Re: ethernet using pic16f877 and enc28j60 Post by: sherm on March 09, 2009, 11:09:22 11:09 I just know the 16F877 very well and thought it could work with ENC28J60.

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. Code: ' * 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.

Title: Re: ethernet using pic16f877 and enc28j60 Post by: titi on August 22, 2012, 06:20:30 18:20 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 (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.

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 :D 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! |
