New EtherShield Library status update

I’ve been working on an updated EtherShield library for a number of weeks now, progress has been slow due to so many other things going on. Here is a taster of what is to come:

Updated library filenames so that it works with both Linux and Windows versions of the Arduino IDE
Converted 8 bit ENC28J60 writes to 16 bit writes where applicable, i.e. it now takes 1 operation to update a register not 2.
Added support for DNS queries, no need to get IP addresses now. Also handles multiple response records and picks the first valid A record.
Updated examples:
- Twitter client now uses supertweet.net to post updates as twitter.com is dropping basic authentication altogether.
- DNS client example
- Retrieve CSV values from a Pachube feed
- Anything else I can think of that will help people use the library!

This is not a final list, just a brief overview of some of the updates coming along.

Hi, can you provide/post a sample on how to send data over tcp to a specific ip:port ?

Nice to read that !
i’m now ready to test it when it will be published.
Congratulation for the job.

Hi, My arduino (with your library) does not send temp on twitter since august,
Is the new library, the solution to repare the twitter client ?

Podría conectarse también a MySQL?

Hi,

this is due to twitter dropping the basic authentication in favour of OAuth. Sadly the little arduino isnt really up to the job of implementing the OAuth protocol. However, there is a solution, in that you can use a proxy site, for example http://www.supertweet.net/. You basically change a couple of values (password and url) then fire your requests to supertweet. This then gets tweeted normally.
I have an updated example in the next release, although a quick post on this wont hurt, so please see http://blog.thiseldo.co.uk/?p=501.

Cheers

If you wish to connect it to MySQL then you would need to pass values to a php script, for example, and have that update the database.

Good question, I’m investigating an issue with TCP client code. I’m not sure if it ever worked correctly. Its just taking slightly longer than I expected.
