Question 1

How do I install micropython-lib packages on my MicroPython board?

Accepted Answer

Use the mip package manager if your board has network connectivity, or mpremote from your PC for serial connections. For example, run 'mip.install("package-name")' on the device or 'mpremote mip install package-name' from the terminal. Freezing into firmware is another option for embedded deployments.

Question 2

What's the difference between micropython-lib and regular Python libraries from PyPI?

Accepted Answer

micropython-lib provides ports of Python libraries adapted for MicroPython's resource constraints, often with reduced functionality and missing features. PyPI libraries are designed for CPython and may not run on microcontrollers due to memory or performance issues.

Question 3

Can I use micropython-lib packages with CPython or other Python versions?

Accepted Answer

No, micropython-lib packages are specifically optimized for MicroPython and may not be compatible with CPython. They are tailored for embedded environments and might lack features or have different implementations, limiting cross-platform use.

Question 4

How to freeze micropython-lib packages into my MicroPython firmware?

Accepted Answer

Include the package's manifest.py in your board manifest using the require() command during firmware build. This embeds the library directly into the binary, reducing RAM usage and startup time for production embedded applications.

Question 5

Are all Python standard library modules available in micropython-lib?

Accepted Answer

Not all modules are available, and those that are often have reduced functionality with missing methods or classes. The python-stdlib directory contains compatible versions, but you should check the specific package for limitations, as noted in the README.

Question 6

micropython-lib vs writing custom drivers: which is better for hardware projects?

Accepted Answer

micropython-lib offers pre-made drivers for common hardware, saving development time and effort. However, for specialized or proprietary hardware, writing custom drivers might be necessary. Evaluate based on community support, documentation, and your project's specific needs.
