A CircuitPython driver for the MAX31856 Universal Thermocouple Amplifier
This driver depends on:
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-max31856To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-max31856To install in a virtual environment in your current project:
mkdir project-name && cd project-name python3 -m venv .venv source .venv/bin/activate pip3 install adafruit-circuitpython-max31856import board import digitalio import adafruit_max31856 # Create sensor object, communicating over the board's default SPI bus spi = board.SPI() # 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) # measure the temperature! (takes approx 160ms) print(thermocouple.temperature) # alternative (non-blocking) way to get temperature thermocouple.initiate_one_shot_measurement() # <perform other tasks> # now wait for measurement to complete while thermocouple.oneshot_pending: pass print(thermocouple.unpack_temperature())API documentation for this library can be found on Read the Docs.
