Sorry for confusion.

I have already fixed my problem with DS18B20. I have no problem. I get nice negative value reading, too. Everything is perfect.

But,

For DS1820, how do we read negative values? When the temp gets below zero, how do we read it? I could not find a PBP sample code for negative part. I have about 50pcs DS1820 left in hand and have a chance of getting rid of them if I can read negative values.


The table is for DS1820.
