Damien George 038df43183 stmhal: Implement selector for USB device mode; improve boot up. 
Can now choose at boot up whether the USB device is CDC+MSC or CDC+HID.
Choice is made by an option in boot.py, with default being CDC+MSC.
HID+MSC is not currently supported, but should be easy to implement.

Boot up now has ability to change the reset mode: hold down USR switch
while booting and LEDs will count from 1 to 7 to indicate the boot mode.
Release USR when correct mode is selected.  Current modes are 1 (normal
boot), 2 (safe mode), 3 (reset FS mode).

The Micro Python project

MicroPython Logo

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.

Major components in this repository:

  • py/ -- the core Python implementation, including compiler and runtime.
  • unix/ -- a version of Micro Python that runs on Unix.
  • stmhal/ -- a version of Micro Python that runs on the Micro Python board with an STM32F405RG (using ST's new Cube HAL drivers).
  • stm/ -- obsolete version of Micro Python for the Micro Python board that uses ST's old peripheral drivers.
  • teensy/ -- a version of Micro Python that runs on the Teensy 3.1 (preliminary but functional).

Additional components:

  • unix-cpy/ -- a version of Micro Python that outputs bytecode (for testing).
  • tests/ -- test framework and test scripts.
  • tools/ -- various tools, including the pyboard.py module.
  • examples/ -- a few example Python scripts.

"make" is used to build the components, or "gmake" on BSD-based systems. You will also need bash and python (2.7 or 3.3) for the stm port.

The Unix version

The "unix" part requires a standard Unix environment with gcc and GNU make. x86 and x64 architectures are supported (i.e. x86 32- and 64-bit). ARM to be confirmed. Porting to other architectures require writing some assembly code for the exception handling.

To build:

$ cd unix
$ make

Then to test it:

$ ./micropython
>>> list(5 * x + y for x in range(10) for y in [4, 2, 1])

Debian/Ubuntu/Mint derivative Linux distros will require build-essentials and libreadline-dev packages installed. To build FFI (Foreign Function Interface) module (recommended, enable in unix/mpconfigport.mk), libffi-dev is required.

The STM version

The "stmhal" 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 stmhal
$ make

You then need to get your board into DFU mode. On the pyboard, connect the 3V3 pin to the P1/DFU pin with a wire (on PYBv1.0 they are next to each other on the bottom left of the board, second row from the bottom).

Then to flash the code 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.
