CircuitPython Installation of DotStar Library

You'll need to install the Adafruit CircuitPython DotStar (https://adafru.it/CKG) 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_dotstar.mpy

adafruit_bus_device

Before continuing make sure your board's lib folder or root filesystem has the adafruit_dotstar.mpy, and

adafruit_bus_device 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 DotStar Library

You'll need to install the Adafruit_Blinka library that provides the CircuitPython support in Python. This may also require

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-dotstar
