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 ...

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 ...

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.

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 ...
