Hi there,
my current setup :
1x Arduino Uno R4 Wifi board
1x Max31865 RTD Converter
1x PT1000 sensor
connection:
Arduino to converter
Port 10 → CS
Port 11 → SDI
Port 12 → SDO
Port 13 → CLK
Port 5V → VIN
Port GND → GND
converter to sensor
RTD+ → red cable of the sensor
RTD- → white cable of the sensor

SPI bus read all 0 or all 1 (0x0000), check MAX31865 wiring & power.
hope someone can help
thx alot
