Micropython is a python3 implementation that has been optimised for micro-controllers and small embedded systems. It also has a "unix" port. It has an MIT license. This is version 1.5.2 of micropython. MicroPython implements the entire Python 3.4 syntax (including exceptions, "with", "yield from", etc.). The following core datatypes are provided: str (including basic Unicode support), bytes, bytearray, tuple, list, dict, set, frozenset, array.array, collections.namedtuple, classes and instances. Builtin modules include sys, time, and struct. Note that only subset of Python 3.4 functionality implemented for the data types and modules. This is the standard micropython source (version v1.5.2), which has been adapted to use reachover infrastructure. At the present time, libffi (from pkgsrc) is used. Alternative locations for libffi can be set using the PKGSRC_PREFIX definition to make.
