Edd Barrett 0d02eb178a Fix undefined termcap symbols on OpenBSD. 
E.g.:
/usr/lib/libreadline.so.4.0: undefined reference to `tgetnum'
/usr/lib/libreadline.so.4.0: undefined reference to `tgoto'
/usr/lib/libreadline.so.4.0: undefined reference to `tgetflag'
/usr/lib/libreadline.so.4.0: undefined reference to `tputs'
/usr/lib/libreadline.so.4.0: undefined reference to `tgetent'
/usr/lib/libreadline.so.4.0: undefined reference to `tgetstr'

Tested on linux too, works.

py On OpenBSD MAP_ANONYMOUS is called MAP_ANON. 2014-01-01 23:16:27 +00:00
pybv3 Add PYBv3 EAGLE files, gerbers, schematic, BOM and assembly guide. 2013-12-22 20:15:41 +00:00
stm Use rm -rf to remove build dir, so it doesn't error out if dir doesn't exist. 2013-12-30 21:02:10 +02:00
tests py: make closures work. 2013-12-30 22:32:17 +00:00
tools Add tools/dfu.py, and use it in stm/Makefile. 2013-12-20 12:07:50 +00:00

The Micro Python project

This is the Micro Python project, which aims to put an implementation of Python 3.x on a microcontroller. The project also includes a small microcontroller board based around the STM32F405RG.

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. For the moment the priority is the hardware.

Major components:

  • 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.
  • pybv3/ -- schematics, gerbers and EAGLE files for revision 3 of the Micro Python board.

Additional components:

  • unix-cpy/ -- a version of Micro Python that outputs bytecode (for testing).
  • tests/ -- test framework and test scripts.
  • tools/ -- various tools.

"make" is used to build the components, or "gmake" on BSD-based systems.

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])

Ubuntu and Mint derivatives will require build-essentials and libreadline-dev packages installed.

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.
