CircuitPython driver for the MAX31855 Thermocouple Amplifier Breakout
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.
Of course, you must import the library to use it:
You also need to create an SPI interface object, and a pin object for the chip select pin. You can use any pin for the CS, but we use D5 here:
from busio import SPI from digitalio import DigitalInOut import board spi = SPI(clock=board.SCK, MISO=board.MISO, MOSI=board.MOSI) cs = DigitalInOut(board.D5)
Next, just create the sensor object:
sensor = adafruit_max31855.MAX31855(spi, cs)
And you can start making measurements:
The temperature is read in degrees Celsius (°C). You have to convert it to other units yourself, if you need it.

To build this library locally you'll need to install the circuitpython-build-tools package.
python3 -m venv .env source .env/bin/activate pip install circuitpython-build-tools
Once installed, make sure you are in the virtual environment:
Then run the build:
circuitpython-build-bundles --filename_prefix adafruit-circuitpython-max31855 --library_location .
Sphinx is used to build the documentation based on rST files and comments in the code. First, install dependencies (feel free to reuse the virtual environment from above):
python3 -m venv .env source .env/bin/activate pip install Sphinx sphinx-rtd-theme
Now, once you have the virtual environment activated:
cd docs sphinx-build -E -W -b html . _build/html
This will output the documentation to
docs/_build/html. Open the index.html in your browser to
view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to
locally verify it will pass.
