      Add pin mapping code. · 51dabac0
      Dave Hylands authored
      This commit also introduces board directories and moves board
      specific config into the appropriate board directory.
      
      boards/stm32f4xx-af.csv was extracted from the STM32F4xx datasheet
      and hand-tweaked.
      
      make-pins.py takes boards/stm32f4xx-af.csv, boards/stm32f4xx-prefix.c,
      and boards/BOARD-NAME/pins.csv as input and generates the file
      build/pins_BOARD_NAME.c
      
      The generated pin file for PYBOARD4 looks like this:
      https://gist.github.com/dhylands/9063231
      
      The generated pins file includes all of the supported alternate
      functions, and includes upsupported alternate functions as comments.
      
      See the commnet block at the top of stm/pin_map.c for details on
      how to use the pin mapper.
      
      I also went ahead and modified stm/gpio.c to use the pin mapper.

      py: VM never throws an exception, instead returns a status and value. · c8f78bc2
      Damien George authored
      Addresses issue #290, and hopefully sets up things to allow generators
      throwing exceptions, etc.

      Implement proper exception type hierarchy. · c5966128
      Damien George authored
      Each built-in exception is now a type, with base type BaseException.
      C exceptions are created by passing a pointer to the exception type to
      make an instance of.  When raising an exception from the VM, an
      instance is created automatically if an exception type is raised (as
      opposed to an exception instance).
      
      Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper.
      
      Handling of parse error changed to match new exceptions.
      
      mp_const_type renamed to mp_type_type for consistency.

      Change mp_obj_type_t.name from const char * to qstr. · a71c83a1
      Damien George authored
      Ultimately all static strings should be qstr.  This entry in the type
      structure is only used for printing error messages (to tell the type of
      the bad argument), and printing objects that don't supply a .print method.

      Make VM stack grow upwards, and so no reversed args arrays. · 20006dbb
      Damien George authored
      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.

      Basic implementation of import. · 66028ab6
      Damien George authored
      import works for simple cases.  Still work to do on finding the right
      script, and setting globals/locals correctly when running an imported
      function.

      Change object representation from 1 big union to individual structs. · d99b0528
      Damien authored
      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).
