Owslave has been superseeded by the M-O-A-T project:
https://github.com/M-o-a-T/moat, and from my brief use (a few months
back, testing only) it works really well, at least on a Mega 8. There
was an introductory post on this list a few months back.
You need to edit the .cfg file to build a configuration, which wasn't
that straightforward (at least at that time), which then creates the .h
files required. There may be better docs today, but regardless well
worth looking in to!

Anybody have a reliable codebase for ATTiny85 1Wire slaves?
The best code I've found is written for a 328P and needs to be ported:
https://github.com/neuoy/OneWireArduinoSlave
There is this, mentioned on this listserve some time ago, but it seems
to have a broken dependency for dev_config.h which is not included in
the git repo:

Colin,
The reason I and most other people use RTDs is because they are more
precise than a typical thermocouple or thermister. You need to do a
good bit more than an LDO and a A/D to make the reader as/more stable
than the RTD. Everything needs to be temperature compensated with
careful circuit choices to get reasonable accuracy. I'm not sure how
much better than a typical thermocouple a setup like you suggested
would be.

Hi All,
Anybody have use for an RTD 1Wire slave? I'm finding I could really
use one, and what's out there is too expensive, not compact and/or
modular enough. I feel as though I'm missing something.
Seems to me a MAX31865, an ATTiny85, an LDO, and a little logic
level conversion would do the trick in a tiny form factor for a
pittance. What ROM address would/could I use for this guy?
Cheers,
Colin
