How to get PIC to ethernet

Question

Hi,I want to interface PIC chips (see website below - I do a lot with them) onto the internet via the router output on our cable modem.Whats a good way to get from general PIC programming to connecting to the internet (ethernet?) via Cat5 connection?I expect a bit of a learning curve here.-- Luhan Monat: luhanis(at)yahoo(dot)com"The Future is not what it used to be..."

This is exactly what Jeremy Bentham does in "TCP/IP Lean". (CMP Books). Take a look.

Edward Cheung developed a great idea for interfacing: using old ISAethernet cards. He won several awards in Circuit Cellar INK for the process.You can find an explanatory article here:BAJ

I saw that early in my looking into embedded internet. I have a wirewrap board interfacing a pic to ISA bus. What got me hung up was "Plug-n-Pray" board I found. If I can get some old ISA cards with jumper addresses I may be able to make that work.

Take a look at Rabbit:

news:...I looked at that in the past.  They seem to have their own microcontroller.  I'm 'embedded' solidly in the PIC camp and don't really want to learn other microcontrollers at this time.Thanks anyway.-- Luhan Monat: luhanis(at)yahoo(dot)com"The Future is not what it used to be..."

I was suggesting an alternative. :)

1) PnP cards often come with a config utility so you can manually configure them. Drop it in a PC and run the utility to turn off PnP and config the settings you want. Then put it in your project and go. Stores like Fry's sell NE2000 cards like this for ~$10. 2) Skip the ISA card slot and use these proto cards for PIC and AVR:

Fred has NE2000, Crystal, and ASIX (NE2000 w/ 10/100) boards - plus driver code. He's also written a book on the subject, and an article in the Oct 2002 CircuitCellar (AVR+ASIX). And... he'll sell you the chips and magnetics for a decent price if you roll your own boards. 3) Here's a newer solution that's turnkey; however, they're pricey (~$50 ea.) and limited in their back-end connectivity. If you just want to put an Internet face on your widget, these are a good fit. If you want to do something high-performance, they're not.

Robert Lacoste · Answer

If you can accept an extra cost on the BOM (but drastically reducing the development cost...) then have a look at the XPort from Lantronix, or similar solution from Digiconnect (Connect-Me). Both are intelligent RJ45 plugs (ie with on-board high-end processor and TCP/IP stack), that you could easily link to your PIC through a Uart link.
