Can't install adafruit-micropython-blinka

[phero]

Hello!

I'm new to MicroPython and Python in general so please forgive me if this is a stupid question.

I'm trying to use a Raspberry Pi Pico with an MCP23017. So in order to install the MCP library i do this:

Code: Select all

python3 -m pip install adafruit-circuitpython-mcp230xx

Which works well.

When I try to run the program to connect to the MCP23017 I get a
Module not found: digitalio

As far as I can see I need to install adafruit-micropython-blinka to fix that problem

But when I try to do that I get an error:

Code: Select all

python3 -m pip install adafruit-micropython-blinka

I also tried to install it in apps like PyCharm and Thonny and they all give the same error.

I'm on MacOS on an M1 MacMini

I hope someone can help me out!

Thank you!

Those pip commands look like you're installing the modules onto your Mac. And while blinka was originally developed for Adafruit by one of the former regulars around here (user cefn), it's gone very much its own way since then. Support for it is generally managed by Adafruit, who will likely suggest you use their CircuitPython system instead of MicroPython.

There is, however, the mcauser/micropython-mcp23017: MicroPython driver for MCP23017 16-bit I/O Expander module (found via the Awesome MicroPython catalogue, which needs to be better known). It won't work exactly like the blinka module, but it will allow you to use the I/O module fairly easily

It may help if you create a Python virtual environment.
That way less chance of insufficient privileges.

You could try my script https://github.com/pappavis/thescript/b ... tualenv.sh which should work fine on MacOS too.
