Support for the ADS1x15 series of analog-to-digital converters. Available in 12-bit (ADS1015)
and 16-bit (ADS1115) versions.
Installation & Dependencies
===========================
This driver depends on:
* `Adafruit CircuitPython `_
* `Bus Device `_
Please ensure all dependencies are available on the CircuitPython filesystem.
This can be most easily achieved by downloading and installing
`the Adafruit library and driver bundle `_ on
your device.
Installing from PyPI
--------------------
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
PyPI `_. To install for current user:
.. code-block:: shell
pip3 install adafruit-circuitpython-ads1x15
To install system-wide (this may be required in some cases):
.. code-block:: shell
sudo pip3 install adafruit-circuitpython-ads1x15
To install in a virtual environment in your current project:
.. code-block:: shell
mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-ads1x15
Usage Example
=============
Single Ended
------------
.. code-block:: python
import time
import board
import busio
import adafruit_ads1x15.ads1015 as ADS
from adafruit_ads1x15.analog_in import AnalogIn
# Create the I2C bus
i2c = busio.I2C(board.SCL, board.SDA)
# Create the ADC object using the I2C bus
ads = ADS.ADS1015(i2c)
# Create single-ended input on channel 0
chan = AnalogIn(ads, ADS.P0)
# Create differential input between channel 0 and 1
#chan = AnalogIn(ads, ADS.P0, ADS.P1)
print("{:>5}\t{:>5}".format('raw', 'v'))
while True:
print("{:>5}\t{:>5.3f}".format(chan.value, chan.voltage))
time.sleep(0.5)
