[OpenTRV-dev] DS18B20 with Arduino

[Damon Hart-Davis]

Hi,

Bo: following our earlier discussions

With a little research I think it should be possible to make the V0.2 work with DS (when running on 3.3V) or TMP, detected at run-time if need be, though there are a number of trickinesses, especially with timing because the DS is slow.

But I have not yet found a sensibly-licensed 1-Wire library for Arduino/ATMega (ie *with* some sort of licence that isn't GPL and pref is BSD or Apache or MIT or similar), so might have to reverse engineer something.

In any case it's not a trivial bit of work, but not insurmountable either.

Rgds
