MAX31865 datasheet

Usage

Important: make sure you properly setup the SPI pins especially for ESP32 before creating the SpiDevice, make sure you install the nanoFramework.Hardware.ESP32 nuget:

//////////////////////////////////////////////////////////////////////
// when connecting to an ESP32 device, need to configure the SPI GPIOs
// used for the bus
Configuration.SetPinFunction(21, DeviceFunction.SPI1_MOSI);
Configuration.SetPinFunction(22, DeviceFunction.SPI1_MISO);
Configuration.SetPinFunction(23, DeviceFunction.SPI1_CLOCK);
// Make sure as well you are using the right chip select

For other devices like STM32, please make sure you're using the preset pins for the SPI bus you want to use. The chip select can as well be pre setup.

SpiConnectionSettings settings = new(1, 42)
{
    ClockFrequency = Max31865.SpiClockFrequency,
    Mode = Max31865.SpiMode1,
    DataFlow = Max31865.SpiDataFlow
};

using SpiDevice device = SpiDevice.Create(settings);
using Max31865 sensor = new(device, PlatinumResistanceThermometerType.PT1000, ResistanceTemperatureDetectorWires.ThreeWire, ElectricResistance.FromOhms(4300));

while (true)
{
    Debug.WriteLine($"Temperature: {sensor.Temperature.DegreesCelsius} ℃");

    // wait for 2000ms
    Thread.Sleep(2000);
}

Note: You can use any PT100 or PT1000 temperature sensor which has 2/3/4 wires.
