This driver enables you to use the Adafruit HTU21D-F temperature and humidity breakout with CircuitPyton.
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.
import time
import board
import busio
from adafruit_htu21d import HTU21D
# Create library object using our Bus I2C port
i2c = busio.I2C(board.SCL, board.SDA)
sensor = HTU21D(i2c)
while True:
print("\nTemperature: %0.1f C" % sensor.temperature)
print("Humidity: %0.1f %%" % sensor.relative_humidity)
time.sleep(2)

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:
source .env/bin/activate
Then run the build:
circuitpython-build-bundles --filename_prefix adafruit-circuitpython-htu21d --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.
