owhttpd -d /dev/ttyS0 -p 80
using this it will test ds2480 and serial bit bang device (auto detect)
could i set it to just use ds2480?

I know I wrote about this few times but there was some update on DS2324
substitute.
There is a board and ATTiny44 program which works just like DS2423
We will be coming out with a replacement for our Hub. It is in the
design stage. There are a few other things that have to get
completed before it gets much attention but it is a high priority.

What "auto detection" are you referring to? Serial ports need to be
specified specifically. USB enumeration is inconsistent, but you can
specify which adapter (in order) to use. i2c address can be specified.
network addresses can be specified. w1 won't let you specify. What else is
there?
Are you

well, if raspberry get 35USD i think a POE (power over ethernet)

there is also the issue of topology: sometime a star topology is a

Thanks Marc
I have connected my network with RJ11 plugs and sockets at many of the
junction points, so if there is a problem I can remove sections to
isolate the problem. I think I am well within 1000ft, so I guess I will
stick my current configuration.
Thanks for your help

Mick,
The problem with 1-wire is that it is has "single ended" data
communications signaling vs. "differential" in rs485 or ethernet over
cat5. If you have the differential on a single twisted pair, the signal
will be very resistant to external noise. With single ended systems,
noise is always

I have noticed in other threads that many people use hubs in their
network. What is the advantage of splitting a network with hubs? I
currently have a single network with 25 DS1820's and a couple of
DS2406. I plan to extend this in the near future, so if there are
advantages to splitting it
what's your installation?

I was thinking the same.
I have a Sheevaplug which I am currently using - with USB to 1Wire
converter.
My total lack of knowledge about I2C devices obviously does not help.
Could you offer some pointers to get more info?

I will definitely buy a RaspberryPi as soon as they are available, and
will want to interface to 1-wire. I had assumed that USB would be the
way to go. Would these boards provide a faster/cheaper/more reliable
way to communicate?

Hi,
Well spotted, I'll take a look and re-work the PCB's (which havn't yet
gone to FAB).
I'm getting an initial run of 10 of each PCB (singe and octo channel) is
there any interest in any spares ?
