# Simple demo of the MAX31865 thermocouple amplifier.

# Will print the temperature every second.

import time

# Initialize SPI bus and sensor.

spi = busio.SPI(board.SCK, MOSI=board.MOSI, MISO=board.MISO)

sensor = adafruit_max31865.MAX31865(spi, cs)

# Note you can optionally provide the thermocouple RTD nominal, the reference

# resistance, and the number of wires for the sensor (2 the default, 3, or 4)

# with keyword args:

#sensor = adafruit_max31865.MAX31865(spi, cs, rtd_nominal=100, ref_resistor=430.0, wires=2)

# Main loop to print the temperature every second.

while True:

# Read temperature.

# Print the value.

print('Temperature: {0:0.3f}C'.format(temp))

# Delay for a second.
