Hello
I cannot get 3 pieces DS18B20 to function properly.
All three sensors show the same temperature. It is the last sensor on the line that determines what the temperature is.
How do I contact for each of the 3 sensors?
I downloaded "DS18X20_Get_Temp_Multiple_Device-1.fcf" and adapted it to 16F690. It is a fcf-file from Matrix Benj. See link below.
Intern clock 8 MHZ

Another question.
When a DS18B20 shows "1360" ~ 85.0. Is the sensor as faulty, or can I do anything.

Hello,

There are lots of posts on these forums about these one wire devices. Hopefully one of the previous posts will help you to get up and running.
