micropython-lib

This is a repository of libraries designed to be useful for writing MicroPython applications.

The libraries here fall into roughly four categories:

• Compatible ports of CPython standard libraries. These should be drop-in replacements for the CPython libraries, although many have reduced functionality or missing methods or classes (which may not be an issue for many use cases).

• "Micro" versions of CPython standard libraries with limited compatibility. These can often provide the same functionality, but might require some code changes compared to the CPython version.

• MicroPython-specific libraries. These include drivers and other libraries targeted at running Python on hardware or embedded systems.

• MicroPython-on-Unix-specific libraries. These extend the functionality of the Unix port to allow access to operating-system level functionality (which allows more CPython compatibility).

Usage

Many libraries are self contained modules, and you can quickly get started by copying the relevant Python file to your device. For example, to add the base64 library, you can directly copy base64/base64.py to the lib directory on your device.

Other libraries are packages, in which case you'll need to copy the directory instead. For example, to add collections.defaultdict, copy collections/collections/__init__.py and collections.defaultdict/collections/defaultdict.py to a directory named lib/collections on your device.

For devices that have network connectivity (e.g. PYBD, ESP8266, ESP32), they will have the upip module installed.

>>> import upip
>>> upip.install('micropython-base64')
>>> upip.install('micropython-collections.defaultdict')
...
>>> import base64
>>> base64.b64decode('aGVsbG8sIG1pY3JvcHl0aG9u')
b'hello, micropython'
>>> from collections import defaultdict
>>> d = defaultdict(int)
>>> d[a] += 1

Future plans (and new contributor ideas)

• Provide compiled .mpy distributions.
• Develop a set of example programs using these libraries.
• Develop more MicroPython libraries for common tasks.
