SetTemperatureRaw(static_cast(value * 16.0f)) īut reading and processing these values might not be supported by all software as it is out of specs. Alternatively a bigger range of values can be set by using: That can easily be achieved - in the worst case be rescaling - and is actually better than the values that can be represented by e.g.

The restrictions here are the resolution and the values have to be in the range -55,0. It creates a bunch of DS18B20 of which every one represents one float value we want to return from our sensor(s). The OneWire-Hub library contains an example called DS18B20_asInterface that does exactly what we need. The only choice I know of is the DS18B20 Thermometer (the DS2438 Battery Monitor is interesting and useful too but quite complex and thus slow among other drawbacks).

For that we need a very simple default 1-wire device that can return floats and is widely supported. Meaning that standard software can be used to read all the values directly (no conversation or binary manipulation needed).

The most important thing is to make a device that can return basically any kind of value in a simple manner.
