Lopy4 with arduino max31855 temperature value always 0

[Miikala]

Hi

I use arduino max31855 and lopy4 without expansion board. Trying to get temperature values from thermocouple
cable but value is always 0.0 . Also tried many example codes but same thing value is 0.
My pins are : CLK = P10 CS = P8 DO = P9.

In atom pymakr i use this code and MAX31855 library.

import MAX31855
from machine import SPI, Pin
spi = SPI(0, mode=SPI.MASTER, baudrate=1000000, polarity=0, phase=0)
cs = Pin('P8', mode=Pin.OUT)
s = MAX31855.MAX31855(spi, cs)
print(s.read())

If somebody had same kind of problems or any suggestions im happy to hear about it.

Thanks.
