Arduino code as requested. I think most of the work is done in the library.
[CODE lang="b4x" title="Arduino code Adafruit_MAX31856"]// This example demonstrates doing a one-shot measurement "manually".
// Separate calls are made to trigger the conversion and then check
// for conversion complete. While this typically only takes a couple
// 100 milliseconds, that times is made available by separating these
// two steps.
#include <Adafruit_MAX31856.h>
// Use software SPI: CS, DI, DO, CLK
//Adafruit_MAX31856 maxthermo = Adafruit_MAX31856(10, 11, 12, 13);
// use hardware SPI, just pass in the CS pin
Adafruit_MAX31856 maxthermo = Adafruit_MAX31856(10);
void setup() {
Serial.begin(115200);
while (!Serial) delay(10);
Serial.println("MAX31856 thermocouple test");
if (!maxthermo.begin()) {
Serial.println("Could not initialize thermocouple.");
while (1) delay(10);
}
maxthermo.setThermocoupleType(MAX31856_TCTYPE_K);
Serial.print("Thermocouple type: ");
switch (maxthermo.getThermocoupleType() ) {

}
maxthermo.setConversionMode(MAX31856_ONESHOT_NOWAIT);
}
void loop() {
// trigger a conversion, returns immediately
maxthermo.triggerOneShot();
//
// here's where you can do other things
//
delay(500); // replace this with whatever
//
//
// check for conversion complete and read temperature
