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:
https://github.com/smurfix/owslave

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
