CircuitPython library for controlling an ADS1x15 ADC.
Project description
Introduction
Support for the ADS1x15 series of analog-to-digital converters. Available in 12-bit (ADS1015) and 16-bit (ADS1115) versions.
Dependencies
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.
Usage Example
Single Ended
import board
import busio
from adafruit_ads1x15.single_ended import ADS1015
i2c = busio.I2C(board.SCL, board.SDA)
adc = ADS1015(i2c)
while True:
# channel 0
print(adc[0].value, adc[0].volts)Differential
import board
import busio
from adafruit_ads1x15.differential import ADS1015
i2c = busio.I2C(board.SCL, board.SDA)
adc = ADS1015(i2c)
while True:
# channel 0 - channel 1
print(adc[(0,1)].value, adc[(0,1)].volts)Contributing

Building locally
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-toolsOnce installed, make sure you are in the virtual environment:
source .env/bin/activateThen run the build:
circuitpython-build-bundles --filename_prefix adafruit-circuitpython-ads1x15 --library_location .Sphinx documentation
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-themeNow, once you have the virtual environment activated:
cd docs
sphinx-build -E -W -b html . _build/htmlThis 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.
