12fa5b3a66 Switch exception throwing to mp_raise helpers. It saves a little code space each time to share the call. 2017-02-24 15:13:07 +01:00

ccbb5e84f9 This introduces an alternative hardware API called nativeio structured around different functions that are typically accelerated by native hardware. Its not meant to reflect the structure of the hardware. 
Docs are here: http://tannewt-micropython.readthedocs.io/en/microcontroller/

It differs from upstream's machine in the following ways:

* Python API is identical across ports due to code structure. (Lives in shared-bindings)
* Focuses on abstracting common functionality (AnalogIn) and not representing structure (ADC).
* Documentation lives with code making it easy to ensure they match.
* Pin is split into references (board.D13 and microcontroller.pin.PA17) and functionality (DigitalInOut).
* All nativeio classes claim underlying hardware resources when inited on construction, support Context Managers (aka with statements) and have deinit methods which release the claimed hardware.
* All constructors take pin references rather than peripheral ids. Its up to the implementation to find hardware or throw and exception.

561844f3ba py: Add MICROPY_FLOAT_CONST macro for defining float constants. 
All float constants in the core should use this macro to prevent
unnecessary creation of double-precision floats, which makes code less
efficient.

93c4a6a3f7 all: Remove 'name' member from mp_obj_module_t struct. 
One can instead lookup __name__ in the modules dict to get the value.

a896951a9a py/objfloat, py/modmath: Ensure M_PI and M_E defined. 
In some compliation enviroments (e.g. mbed online compiler) with
strict standards compliance, <math.h> does not define constants such
as M_PI.  Provide fallback definitions of M_E and M_PI where needed.

4b72b3a133 py: Change type signature of builtin funs that take variable or kw args. 
With this patch the n_args parameter is changed type from mp_uint_t to
size_t.

17298af61e py/modmath: Add domain error checking to sqrt, log, log2, log10. 
These functions will raise 'ValueError: math domain error' on invalid
input.

a24eafacc9 py/modmath: Make log2, log10 and hyperbolic funcs be SPECIAL_FUNCTIONS. 
Will be included only when MICROPY_PY_MATH_SPECIAL_FUNCTIONS is enabled.

Also covers cmath module (but only log10 is there at the moment).

6d1eabfeaa unix/mpconfigport: Move log2() definition to modmath.c. 
It's safer to define it where it's used, defining it for all source files
may lead to hard to diagnose conflicts in corner cases.

5cbeacebdb py: Make math special functions configurable and disabled by default. 
The implementation of these functions is very large (order 4k) and they
are rarely used, so we don't enable them by default.

They are however enabled in stmhal and unix, since we have the room.

3b603f29ec Use MP_DEFINE_CONST_DICT macro to define module dicts. 
This is just a clean-up of the code.  Generated code is exactly the
same.

fb510b3bf9 Rename bultins config variables to MICROPY_PY_BUILTINS_*. 
This renames:
MICROPY_PY_FROZENSET -> MICROPY_PY_BUILTINS_FROZENSET
MICROPY_PY_PROPERTY -> MICROPY_PY_BUILTINS_PROPERTY
MICROPY_PY_SLICE -> MICROPY_PY_BUILTINS_SLICE
MICROPY_ENABLE_FLOAT -> MICROPY_PY_BUILTINS_FLOAT

See issue #35 for discussion.

04b9147e15 Add license header to (almost) all files. 
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

df6567e634 Merge map.h into obj.h. 
Pretty much everyone needs to include map.h, since it's such an integral
part of the Micro Python object implementation.  Thus, the definitions
are now in obj.h instead.  map.h is removed.

caac542b23 Proper support for registering builtin modules in ROM. 
Comes with some refactoring of code and renaming of files.  All modules
are now named mod*.[ch].
