2 Wire Resistance measurement circuit for PT100

Hello everyone,
I require help for building a circuit that can measure resistance (2 Wire Resistance Measurement between (0,1 Ohm..50 MOhm) of PT 100 using STM32. Please can you guide me with the design circuit?
Kind Regards,
Kunal

That does not make much sense.

A PT100 temperature sensor will have a resistance of 100 Ohm at 0 degC, and 138 Ohm (from memory) at 100 degC.
Why on earth do you want to be able to measure from 0.1 Ohm to 50M Ohm ?

Hello,
Sorry for tying it with Pt-100, But in General i wanted to ask How can I measure resistance from (0,1 Ohm..50 MOhm) using 2 wire resistance measurement.

You need to know voltage and current and then do this hard eq.
R=U/I
