Attempting to understand how to integrate 'utypes' module into my project?

[Nodi-Rubrum]

Reviewing the following (external) library module for MP, and I am not sure how to include the 'utypes' module into my project?

I am using Thonny IDE at the moment, since it is typically easy to use, but seem to recall that you can use 'mpremote' as well? I would need to setup a python virtual environment to install and use mpremote (i.e. avoid system wide install using pip), have no issue doing this, if someone would outline the steps of using mpremote? Or point me to online example of using same?

See the official doc for instructions on how to install with mpremote.

or indeed, how to install it.

pipx is my preferred route, especially as you can pipx upgrade-all and get the latest and greatest version automatically when it upgrades

[Nodi-Rubrum]

So I get this to work... for example...

# mpremote connect /dev/ttyUSB0 mip install github:peterhinch/micropython-mqtt
Install github:peterhinch/micropython-mqtt
Installing github:peterhinch/micropython-mqtt/package.json to /lib
Installing: /lib/mqtt_as/__init__.py
Installing: /lib/mqtt_as/mqtt_v5_properties.py
Installing: /lib/mqtt_as/range.py       
Installing: /lib/mqtt_as/range_ex.py    
Installing: /lib/mqtt_as/clean.py       
Installing: /lib/mqtt_local_example.py
Done

But something like...

# mpremote connect /dev/ttyUSB0 mip install github:micropython/extmod/asyncio
Install github:micropython/extmod/asyncio
Installing github:micropython/extmod/asyncio/package.json to /lib
Package may be partially installed

Fails... thinking I could try to load something 'generic' as a validation step?

Moreover, I don't seem to see anywhere in the github repo for micropython, even in extmod? Any utypes or even ctypes library? The source I am trying to use just references 'utypes' so was thinking it was just an extmod not included in core micropython images? And I tried to use an A.I. and was completely useless results returned, guess I don't know how correctly prompt the A.I. as well.

Oh, and I fixed the referenced link above... it was broken in the original query.

[peterhinch]

asyncio is not the best example as it is built-in to MicroPython firmware. To install the "pickle" library, assuming you have connectivity between the PC and your target, all you need is

$ mpremote mip install "pickle"

[Nodi-Rubrum]

Yeah, that was just a test for my setup. Was trying to figure out if I had the repo path wrong... your documentation on using mqtt_as was painless to follow, and execute. I cannot seem to find the exact 'utypes' library the original code references... I suspect it was unique to the IDE setup the author used, and that IDE is now dead... I cannot even install it on Linux given some of the key libraries for the IDE are completely depreciated.

If you need uctypes, it's probably built-in. What board are you using?

MicroPython's built-in help() will be of much more direct use than any AI prompt.

And there it is on my board: below uasyncio and above vfs.

I am testing the code (per the original link) with uctypes... I was trying to find the 'utypes' the original library author used, but the IDE he recommended is dead, no longer supported, and he makes no reference to how he found or used the libraries his code relies on. However, the more I look at the code, the more I think he is just using very common ctypes structures so uctypes may work with the original code. Kinda a bummer... some of the most recent code for BMX280 sensors for use with ESP32 on github is orphaned by an odd library.

[peterhinch]

Is this any help in finding a driver?

Cool site! Thanks
