You can start out by creating a MAX31856 object with either software SPI (where all four pins can be any I/O) using

Or you can use hardware SPI. With hardware SPI you

must

use the hardware SPI pins for your Arduino - and each

arduino type has different pins! Check the SPI reference to see what pins to use. (https://adafru.it/d5h)

In this case, you can use any CS pin, but the other three pins are fixed

Once started, you can initialize the sensor with

You'll also need to set the thermocouple type, remember there's a lot of options! Set the type with:

Your options for the

TCTYPE

are:

MAX31856_TCTYPE_B

MAX31856_TCTYPE_E

MAX31856_TCTYPE_J

MAX31856_TCTYPE_K

MAX31856_TCTYPE_N

MAX31856_TCTYPE_R

MAX31856_TCTYPE_S

// Use software SPI: CS, DI, DO, CLK

Adafruit_MAX31856 max = Adafruit_MAX31856(10, 11, 12, 13);

// use hardware SPI, just pass in the CS pin

Adafruit_MAX31856 max = Adafruit_MAX31856(10);

max.begin()

max.setThermocoupleType(MAX31856_TCTYPE_xxx)
