@ Dimitris
 
Seems you should follow the basic lectures instead of poking around with some fancy microcontrollers.
Even with the 1k pullup resistor you will have to learn about the intricacies of voltage dividers where 1 of the resistors is variable.
 
Could it be rge list of values you gave in your first posting is not from the circuit you gave us later?
Or did I miss the fact that you're using Vrefs different from VDD / VSS?

PEBKAC / EBKAC / POBCAK / PICNIC (eventually see en.wikipedia.org)

My pt1000 has only two wires
Here is the table https://www.vdhproducts.c...s/2015/01/sm8000en.pdf

Do you understand how to read that table?
i.e. can you calculate the resistance of your sensor at 0 degrees and 300 degrees?
 
 

Worst forum problems are now fixed, but the damn firewall is still there.
