      Hi!

      I have a MAX 31865 card from adafruit and a PT100 sensor. The resistance Rref on this board is 430 Ohm. The temperature readings are not correct. After the calculations, I received a new resistance - 360 ohms. Is it so? A military secret?

      Thanks you!

        Version 1.20 firmware supports the R parameter of the M305 command when using PT100 sensors. So add R430 to the appropriate M305 command.
