Experimental Port of The MicroPython Project to 8-Bit AVR Architecture Devices, specifically the Atmega16U2 found on the Arduino USB2SERIAL and Arduino UNO Boards. The project aims to put an implementation of Python 3.x on microcontrollers and small embedded systems. You can find the official website at micropython.org.

The connector that comes with the standard Atmel-ICE Debugger has a nub which prevents it from being plugged in
the wrong way round in most cases. Unfortunately, it prevents connection the right way round on the Atmega16u2
found on the Arduino Uno Rev3. You will need a 2x3 2.54mm Pitch Standoff Header as pictured to connect it properly.

MicroPython implements the entire Python 3.4 syntax (including exceptions, with, yield from, etc., and additionally async/await keywords from Python 3.5). 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, etc. Select ports have support for _thread module (multithreading). Note that only a subset of Python 3 functionality is implemented for the data types and modules.

MicroPython can execute scripts in textual source form or from precompiled bytecode, in both cases either from an on-device filesystem or "frozen" into the MicroPython executable.

See the repository http://github.com/micropython/pyboard for the MicroPython board (PyBoard), the officially supported reference electronic circuit board.

• py/ -- The Core Python implementation, including compiler, runtime, and core library.
• mpy-cross/ -- The MicroPython cross-compiler which is used to turn scripts into precompiled bytecode.
• ports/minimal/ -- A minimal MicroPython port. Start with this if you want to port MicroPython to another microcontroller.
• ports/avr8/ -- Experimental 8-Bit AVR MicroPython port.
• tests/ -- Test framework and test scripts.

The subdirectories above may include README's with additional info.

Building MicroPython ports may require some dependencies installed. Suggested packages include but are not limited to the following:

build-essential, gcc-make, <architecture>-<platform>-gcc, python3

Additionally, to develop and compile the experimental 8-Bit AVR source code, you will need to install and configure Microchip Studio and the LUFA Extension. The user interface is borrowed from Microsoft Visual Studio and Extensions install in the same way. https://www.microchip.com/en-us/development-tools-tools-and-software/microchip-studio-for-avr-and-sam-devices
