I have a MAX31855 breakout board then I tried the Adafruit library but it didn't work right. 3.3 is the Vin and SPI pins are interfaced to 5V arduino. When I put level shifter, the library works smooth.

This library works very well. Just extra note on the level-shifter.

For a 5V board, use 5V for Vin as well. https://learn.adafruit.com/thermocouple/arduino-code#adding-a-display-3-15
