Re: [LacrosseWS] Re: TX-23U serial protocol
Rich, thanks for your interest.
Thanks to my friends Alfonso and Galia, the page has been translated:
We welcome any corrections to the text, since they are not native speakers.
The bad news, for the new version, everything is for writing . As soon as I can, I will add new information.

My Spanish is a bit rusty but I took a quick look at Cristobal's website
and I feel that he's already done most, if not all, of the ground work
that an open source weather station needs. He's even got a cloud
sensor! :) I think this is worth a deeper look and maybe a
collaborative effort to get his information translated better than I can.
