Re: Re: Tell me about 1-wire...

Yes, I've gone for CAT 5 cable (Clipsal pink actually) and 5V powered
from the start - seems to remove some unknowns. I do get some drop outs,
even after increasing the poll time to 1.25s, but expect this is because
I've got things plugged into a breadboard and not yet soldered so am not
too worried.

1-wire software? For my current prototype I'm using digitemp to read my
LinkUSB and rrdtool for graphs, running on Ubuntu on an O2 Joggler. I am
planning to move to owfs when I get time. For the "final" version
I was thinking of using an opn-one (it would be nice to have an
embedded/independent/reliable heating controller) but that has been
discontinued so probably owfs, maybe with MisterHouse, on a Buffalo
Linkstation NAS.

Hi Guys,

1-wire is pretty robust. On thing I would say is that unless you've got a
reason, go for 5V powered sensors, I've not had any problems with missed
readings doing this.

Not sure what plans you have for software for reading your 1-wire nets ?

Cheers

Stuart
