Python 3 Check

We assume you already have Python 3 installed on your computer. Note we do not support Python 2 - it's deprecated and no longer supported!

At your command line prompt of choice, check your Python version with python3 --version

Install hidapi

From the command line, manually install hidapi with:

pip3 install hidapi

pip3 install hidapi

Install Blinka

To install Blinka and its dependencies, run:

pip3 install adafruit-blinka

pip3 install adafruit-blinka

Set Environment Variable 

You'll need to set this variable every time before running CircuitPython code. To do this, we set the environment variable to BLINKA_MCP2221.,

You can set the variable by running:

export BLINKA_MCP2221="1"

export BLINKA_MCP2221="1"

Then, verify that the variable is set by running:

echo $BLINKA_MCP2221

echo $BLINKA_MCP2221

Check that Platform was detected

In the same terminal window you ran export BLINKA_MCP2221="1", run python3.

At the REPL, run:

import board

dir(board)

If you get no errors and see a list of all the pins available, you're good to go!
