Make VM stack grow upwards, and so no reversed args arrays. Change state layout in VM so the stack starts at state[0] and grows upwards. Locals are at the top end of the state and number downwards. This cleans up a lot of the interface connecting the VM to C: now all functions that take an array of Micro Python objects are in order (ie no longer in reverse). Also clean up C API with keyword arguments (call_n and call_n_kw replaced with single call method that takes keyword arguments). And now make_new takes keyword arguments. emitnative.c has not yet been changed to comply with the new order of stack layout.
This is the Micro Python project, which aims to put an implementation of Python 3.x on a microcontroller.
WARNING: this project is in its early stages and is subject to large changes of the code-base, including project-wide name changes and API changes. The software will not start to mature until March 2014 at the earliest.
See the repository www.github.com/micropython/pyboard for the Micro Python board. At the moment, finalising the design of the board is the top priority.
Major components in this repository:
Additional components:
"make" is used to build the components, or "gmake" on BSD-based systems. You will also need bash and python3, and python2 for the stm port.
The "unix" part requires a standard Unix environment with gcc and GNU make. 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])
Ubuntu and Mint derivatives will require build-essentials and libreadline-dev packages installed.
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.
