1. On http://www.espruino.com/WIZnet the link to the git builds doesn't work, sorry

2. Is there any particular reason for the choice of the WIZ550io module? Just wondering
   if http://www.shopwiznet.com/wiz820io might work as it's smaller. It's an older chip, but maybe the API is the same? (I'll check if you don't immediately know)

Thanks

Thanks. I'll update the link. For now it is http://www.espruino.com/binaries/git/commit_date/ - just choose the latest.

I think the w550io is one of the latest ones - but yes the API is similar so you might be able to compile with others. Hopefully at some point we will get them all in one binary.

I have two of the WIZ820io modules, but I am a total noob when it comes to the Espruino. How would I go about adding support for the WIZ820io module? I.e which files would need to be touched?
Thanks for any pointers!

Hi Mike,

I'd look in:
https://github.com/espruino/Espruino/tree/master/libs/network/wiznet

You'll need to download Wiznet's drivers for their site, and put the W5200 folder in there beside the W5500 folder.

Then just change the definitions at the top of this file:

https://github.com/espruino/Espruino/blob/master/libs/network/wiznet/Ethernet/wizchip_conf.h

And hopefully it will work... maybe :)

Hi!

I would also like to get something more common. Getting the Wiz550io is like $17 for the module itself and $40 for shipping. eBay is full of W5100 Arduino shields under $10 (free international shipping).

Do you think the w5100 would work with some of the tweaking mentioned above? Or is there any fundamental problem? From what I can see is that the w5500 has double the internal buffer and number of channels. Something I could live with wrt features.

Any hints welcome!

It's definitely worth a try. I know that in wizchip_conf.h there's a line:

  define _WIZCHIP_                      5500   // 5100, 5200, 5500

So my guess is you may just need to grab the files for the 5100, add them to the Makefile , and then change that line. It may end up being quite easy!

Not any more! It looks like a civilized vendor is selling them now! $3.50 shipping in the states... Still $18 for the module, but $22 vs $10 is a very different calculus than $57 vs $10.

Thanks for the update! I'll update the documentation on WIZnet with that...

Well, not for Europe I am affraid ;(

United States Postal Service Priority Mail Express International $46.00 - $58.00

The W5100's would ship free anywhere on the globe. $10 vs $20 is still very significant when you want to build a network of devices :)
