Max31865

Hey everyone,

same as a lot of people I am using a Max31865 with a PT100 :

With the example code that Adafruit give in order to get the temperature and nothing works I think that I connect the wires correctly and use the right code.

17:20:31.853 → Ratio = 0.00000000
17:20:31.853 → Resistance = 0.00000000
17:20:31.853 → Temperature = -242.02
17:20:31.947 →
17:20:33.010 → RTD value: 0
17:20:33.010 → Ratio = 0.00000000
17:20:33.010 → Resistance = 0.00000000
17:20:33.010 → Temperature = -242.02
17:20:33.104 →
17:20:34.171 → RTD value: 0
17:20:34.171 → Ratio = 0.00000000
17:20:34.171 → Resistance = 0.00000000
17:20:34.171 → Temperature = -242.02
17:20:34.237 →
17:20:35.320 → RTD value: 0
17:20:35.320 → Ratio = 0.00000000
17:20:35.320 → Resistance = 0.00000000
17:20:35.320 → Temperature = -242.02
17:20:35.414 →
17:20:36.504 → RTD value: 0
17:20:36.504 → Ratio = 0.00000000
17:20:36.504 → Resistance = 0.00000000
17:20:36.504 → Temperature = -242.02
17:20:36.551 →
17:20:37.663 → RTD value: 0
17:20:37.663 → Ratio = 0.00000000
17:20:37.663 → Resistance = 0.00000000
17:20:37.663 → Temperature = -242.02
17:20:37.710 →

Somebody have any idea about the problem ?

Clock-pin usually is pin 13

Connect to the pin 13 , no difference still not working …

..use hardware SPI (pins (10..13)
Ensure MOSI/MISO are not swapped
