CircuitPython Installation of INA260 Library
You'll need to install the Adafruit CircuitPython INA260 (https://adafru.it/EGL) library on your CircuitPython board.
First make sure you are running the latest version of Adafruit CircuitPython (https://adafru.it/Amd) for your board.
Next you'll need to install the necessary libraries to use the hardware--carefully follow the steps to find and install these
libraries from Adafruit's CircuitPython library bundle (https://adafru.it/uap). Our CircuitPython starter guide has a great
page on how to install the library bundle (https://adafru.it/ABU).
For non-express boards like the Trinket M0 or Gemma M0, you'll need to manually install the necessary libraries from
the bundle:
adafruit_ina260.mpy
adafruit_bus_device
adafruit_register
Before continuing make sure your board's lib folder or root filesystem has the adafruit_ina260.mpy,
adafruit_bus_device, and adafruit_register files and folders copied over.
Next connect to the board's serial REPL (https://adafru.it/Awz)so you are at the CircuitPython >>> prompt.
Python Installation of INA260 Library
You'll need to install the Adafruit_Blinka library that provides the CircuitPython support in Python. This may also
require enabling I2C on your platform and verifying you are running Python 3. Since each platform is a little different,
and Linux changes often, please visit the CircuitPython on Linux guide to get your computer
ready (https://adafru.it/BSN)!
Once that's done, from your command line run the following command:
sudo pip3 install adafruit-circuitpython-ina260
If your default Python is version 3 you may need to run 'pip' instead. Just make sure you aren't trying to use
CircuitPython on Python 2.x, it isn't supported!
CircuitPython & Python Usage
To demonstrate the usage of the sensor we'll initialize it and read the current and voltage from the board's Python
REPL.
Run the following code to import the necessary modules and initialize the I2C connection with the sensor:
Now you're ready to read values from the sensor using these properties:
import time
import board
import busio
import adafruit_ina260
i2c = busio.I2C(board.SCL, board.SDA)
ina260 = adafruit_ina260.INA260(i2c)
