Description

I'm going to start to implement a driver for the MAX31865 RTD ADC. Examples of RTDs are Pt100 or Pt1000 temperature sensors.

Although it has similarities with the MAX31855 thermocouple ADC, its memory map is somewhat more complex and the temperature conversion is totally different. Besides, it has a number of configuration options that the MAX31855 doesn't have.

That's why I think I'd better be off implement the MAX31865 in a totally separate driver. Comments are welcome.
