I have two DS18B20 probes that I connect to my 1wire bus. I have noticed they only display 0.5C resolution in my WC registers. As I understand it both models only have 0.5c accuracy but the DS18B20 has selectable 9-12 bit resolution.
If I connect a DS18B20 part and only get 0.5c resolution,
- does this mean only the DS1820 part is supported?
- is support for the "B" part coming in the near future?
- is there a way to change the resolution of the communication?
- was the 0.5c resolution kept intentionally?
- is support for the DS1820 being or has been discontinued?
- am I missing something on this unit's usage?
Used for outside temperatures 0.5c resolution is just fine IMHO but for inside temperature measurements 0.5c is too coarse. O.1c is needed for many applications like, duct temperature measurements, room temperatures or room temperature proportional balancing.
I understand this device only offers 0.5c accuracy but the last few 0.1c is relative to comfort or comparison anyway and can be human compensated for.
