CircuitPython library for controlling an ADS1x15 ADC.

Project description

Introduction

Documentation Status Discord Build Status

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:

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:

pip3 install adafruit-circuitpython-ads1x15

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-ads1x15

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-ads1x15

Usage Example

Single Ended

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)
