Re: [Owfs-cvs] Wich type of Link device?

[Paul A. <pal...@ea...>]

Ahh, good. You found the real discussion area.

The simple answer is that they probably all work just fine.

#1 is the only one I own, so it's the only one I've tested. (As a free
project, it's a little hard justifying purchasing every variant on the
market).

I think that #2 and #3 should work fine. You'll see devices with family
code 10(temperature) and 26(humidity) (and 01 for ID).

Although the humidity hasn't been tested, I assume it is the same design
as a widely published DS2438-based circuit that is also made by
Aageletronica, that does work out of the box.

And finally, I think the "f" device is pointless. It does give you a
unique label for your LINK, but unless you have hundreds of them on a
factory floor and want to track their location, you'll never use the
data. There is also nothing in 1-wire design that tells you that that
address is the LINK. It could be any device on the bus.

If you buy one of the devices other than #1 (or even the RJ45 version of
the LINK) please report your findings. I'll update the website with the
information.
