MAX31865 driver test

About

This is a test application for the MAX31865 driver, a RTD-to-digital converter, tailored for Pt100 and Pt1000 sensing elements.

Usage

This test application will initialize a MAX31865 device to output the temperature every second.

The driver uses fixed-point arithmetic for all conversions. To do so, it needs a lookup table (LUT). A default one is provided for a Pt100 and a 330Ω reference resistor. The user can generate one for different resistor values with the dist/genlut.py script.
