A big change. Micro Python objects are allocated as individual structs with the first element being a pointer to the type information (which is itself an object). This scheme follows CPython. Much more flexible, not necessarily slower, uses same heap memory, and can allocate objects statically. Also change name prefix, from py_ to mp_ (mp for Micro Python). |

The Micro Python project
This is the Micro Python project, which aims to put an implementation of Python 3.x on a microcontroller.
Subdirectories:
- py/ -- the core Python implementation, including compiler and runtime.
- unix/ -- a version of Micro Python that runs on Unix.
- stm/ -- a version of Micro Python that runs on the Micro Python board with an STM32F405RG.
"make" is used to build the components.
The unix version
The "unix" part requires a standard Unix environment with gcc. It works only for 64-bit machines due to a small piece of x86-64 assembler for the exception handling.
To build:
$ cd unix
$ make
Then to test it:
$ ./py
>>> list(5 * x + y for x in range(10) for y in [4, 2, 1])
The stm version
The "stm" part requires an ARM compiler, arm-none-eabi-gcc, and associated bin-utils. For those using Arch Linux, you need arm-none-eabi-binutils and arm-none-eabi-gcc packages from the AUR. Otherwise, try here: https://launchpad.net/gcc-arm-embedded
To build:
$ cd stm
$ make
Then to flash it via USB DFU to your device:
$ dfu-util -a 0 -D build/flash.dfu
You will need the dfu-util program, on Arch Linux it's dfu-util-git in the AUR.
