A quick search on Wikipedia returned a table with the SPI settings for each mode. I chose SPI mode 1 and a hefty clock divider of 256. I also set up an output pin to use as the Chip Select pin.

This easily covers the RTD temperature range of –200°C to 384 ... To emulate nonlinear characteristics of a real RTD, use a lookup table to generate voltages according to discrete temperature ...

You can usethe constant 0.00385Ω/Ω/°C to approximate the resistancechange over temperature for the platinum RTD element. Incontrast, the NTC (negative-temperature-coefficient) thermistorhas a negative ...

Temperature sensitive materials used in the construction of RTDs include platinum, nickel, and copper; platinum being the most commonly used. Important characteristics of an RTD include the ...

Arguably, this advice applies to the circuit design used in many RTD sensors that quietly and efficiently measure temperature in industrial manufacturing facilities worldwide. However, to meet the ...

Notice how the calibration values change when board temperature changes between sample 2 and 3 in the above table. To gather the data, the software followed these steps: 1.
