A CircuitPython driver for the MAX31856 Universal Thermocouple Amplifier

This driver depends on:

• Adafruit CircuitPython
• Bus Device

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-max31856

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-max31856

To install in a virtual environment in your current project:

mkdir project-name && cd project-name python3 -m venv .env source .env/bin/activate pip3 install adafruit-circuitpython-max31856

import board import busio import digitalio import adafruit_max31856 # create a spi object spi = busio.SPI(board.SCK, board.MOSI, board.MISO) # allocate a CS pin and set the direction cs = digitalio.DigitalInOut(board.D5) cs.direction = digitalio.Direction.OUTPUT # create a thermocouple object with the above thermocouple = adafruit_max31856.MAX31856(spi, cs) # print the temperature! print(thermocouple.temperature)
