Welcome to the Python-on-a-Chip Project!
This project's goals are to develop the PyMite virtual machine, device drivers, high-level libraries and other tools to run a significant subset of the Python language on microcontrollers without an OS. Please join the python-on-a-chip google group to discuss this project

Features of the PyMite VM:
- Requires roughly 40 KB program memory and initializes in under 3 KB of RAM
- Supports integers, floats, tuples, lists, dicts, functions, modules, classes, generators, decorators and closures
- Supports 25 of 29 keywords and 89 of 112 bytecodes from Python 2.5
- Can run multiple stackless green threads (round-robin)
- Has a mark-sweep garbage collector
- Has a hosted interactive prompt for live coding
- Licensed under the GNU GPL ver. 2
The PyMite VM DOES NOT HAVE:
- A built-in compiler
- Any of Python's libraries (no batteries included)
- A ready-to-go solution for the beginner (you need to know C and how to work with microcontrollers)
The release can be downloaded from the Downloads tab above. However, we recommend checking out the head of the subversion repository.
