ilter, the number and
channels used in any hubs (and the hub design being used), along with
the temperature sensor wiring (powered or parasitic), the delivered
power voltage and the chip revision if known.
Hope this helps the software efforts,

Hi Jan,
I don't suggest that a OWFS address hardware issues other than at a
"semantics" level. There are indeed many other standards for wiring and
connectors (But for 1-wire, 1WRJ45, The Dallas RJ11/12 standard are the
most common these days).
IMO, we are likely to see more 1-wire devices in t
ually help offset the costs of running the
group. And a good simple logo is a decent start towards that.
Cheers,
Dave

Using Tomcat but need to do more? Need to
parts. In general I prefer the I2C thermostat
chips though...so this is really more of why not than being the best
answer possible. Ideas for it are welcome, contact me so I can judge
interest..
Cheers,

nother protocol, run it in its own cable at least
from the 1-wire network.
Hope this helps,

Join SourceForge.net's Techsay panel and yo
ontrol over the cable power should there be.. .but that's
another issue. Anyway always glad to discuss any of this off line...
what's most important is to select a cable standard and stick to it for
all your 1-wire devices.
BTW, powered temp sensors can perform faster than parasitic ones..
Hi Paul,
I'll contact you off line to send you a schematic and to discuss this
further.. there are a couple options to doing a 1-wire automatic
thermostat.
Cheers,

Using Tomcat but need to do more? Need to support web services, security?
Get stuff done quickly with pre-integrated tec
oller, a
2N700DW and a couple resistors. I also have some better answer if
needed.
It should also be possible to do the reset (once you take care of the
hardware problem) with overdrive speeds I believe. But again there are
some better hardware answers for 1-wire thermostats.
Cheers
etc..
With the greatest resolution being the DS18B20 sensors.
Hope this helps somewhat...

nyway, so I like to use a seperate sensor
for this normally), and has a 16bit current sense and a PIO..could be
interesting.

free to
suggest anything and not have to worry about repercussions to start with and
things can move faster.. As soon as their's a straw-man it would be
published so the rough edges could be knocked off by everyone.

lly shifts several things and
unlesss done properly will lead to a big mess in the future.
If your interested, let me know.

d bad, its is not a huge problem.). Device key being
the DS2409 ID or EEPROM. .I suppose ideally a system would scan for these
devices (EPROM,EEPROM, HUBS etc.) and build a table when found. Thus the
routing and device addresses for all parts are pre-known, for a fixed
complex network.
