MicroPython Built-In Libraries¶

A number of libraries have been written for MicroPython, these are built-in to a port and can be imported by Python programs. The Satlink 3 and XLink 500 port of MicroPython initially includes all the libraries that could be easily ported and did not require additional hardware or conflict with the use of Sutorn hardware. Some of the libraries are bare bones ports, and most are optional.

Nice documentation of libraries available for the pyBoard port of MicroPython: http://docs.micropython.org/en/v1.8.3/pyboard/library/index.html

Here’s a list of the standard libraries that have been ported to the Satlink 3 and XLink 500:

array
builtins
cmath
collections
gc
math
micropython
struct
sys
errno
_thread

Here’s a list of the optional libraries that have been ported to the Satlink 3 and XLink 500 (which ones we keep is tbd):

umachine
pyb
stm
binascii
re
zlib
json
heapq
hashlib
time
struct
machine
urandom
uctypes
os

Currently not supported:

select
lwip
framebuf
btree
axtls
mbedtls
timeq
webrepl
websocket
dupterm
vfs

MicroPython Standard Libraries¶

MicroPython takes a minimalistic approach but yet tries to support as much of Python 3.4/3.5 as possible. To do this any standard Python libraries which can be written in Python are written in Python. It looks very impressive, but many of the libraries are just stubs. For instance if you look at ‘poplib’ and examine ‘poplib.py’ the last remark for it was “poplib: Add dummy module” indicating that the last update only created a “dummy module” or a stub for where code should go in the future. It’s also possible to embed precompiled Python code into a port using a concept called “frozen modules”. The future usefulness of these libraries is up to the community.

MicroPython Cross Compiler and Windows Version.¶

Roberthh has a web page with a pre-built copy of MicroPython built for Windows, as well as the mpy-cross Cross Compiler that converts .py in to .mpy. The latest version of mpy-cross is not compatible with the version of uPy Satlink 3 and XLink 500 are currently using, but we can access the history, and the Oct 11, 2016 version seems to work. MicroPython.exe is based on the Linux port, and will have differences from our port.
