* all: Use the name MicroPython consistently in commentsAlexander Steffen2017-07-31
| | | | | There were several different spellings of MicroPython present in comments, when there should be only one.
* all: Unify header guard usage.Alexander Steffen2017-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code conventions suggest using header guards, but do not define how those should look like and instead point to existing files. However, not all existing files follow the same scheme, sometimes omitting header guards altogether, sometimes using non-standard names, making it easy to accidentally pick a "wrong" example. This commit ensures that all header files of the MicroPython project (that were not simply copied from somewhere else) follow the same pattern, that was already present in the majority of files, especially in the py folder. The rules are as follows. Naming convention: * start with the words MICROPY_INCLUDED * contain the full path to the file * replace special characters with _ In addition, there are no empty lines before #ifndef, between #ifndef and one empty line before #endif. #endif is followed by a comment containing the name of the guard macro. py/grammar.h cannot use header guards by design, since it has to be included multiple times in a single C file. Several other files also do not need header guards as they are only used internally and guaranteed to be included only once: * MICROPY_MPHALPORT_H * mpconfigboard.h * mpconfigport.h * mpthreadport.h * pin_defs_*.h * qstrdefs*.h
* py/smallint: Allow to override MP_SMALL_INT_MIN et al.Damien George2016-01-08
| | | | | This allows a port to specify exactly how many bits are in a small int (eg for a uPy bytecode cross compiler).
* py: Add support for 64-bit NaN-boxing object model, on 32-bit machine.Damien George2015-11-29
| | | | | | | | | | | | | To use, put the following in mpconfigport.h: #define MICROPY_OBJ_REPR (MICROPY_OBJ_REPR_D) #define MICROPY_FLOAT_IMPL (MICROPY_FLOAT_IMPL_DOUBLE) typedef int64_t mp_int_t; typedef uint64_t mp_uint_t; #define UINT_FMT "%llu" #define INT_FMT "%lld" Currently does not work with native emitter enabled.
* py: Add object repr "C", where 30-bit floats are stuffed in obj word.Damien George2015-10-20
| | | | | | This new object representation puts floats into the object word instead of on the heap, at the expense of reducing their precision to 30 bits. It only makes sense when the word size is 32-bits.
* unix/modtime: Implement ticks_ms(), ticks_us() and ticks_diff().Paul Sokolovsky2015-10-19
| | | | | All of these functions return positive small int, thus range is 2 bits less than word size (30 bit on 32-bit systems, 62 bit on 64-bit systems).
* py: Allow configurable object representation, with 2 different options.Damien George2015-04-03

* py: Move to guarded includes, everywhere in py/ core.Damien George2015-01-01
| | | | Addresses issue #1022.
* Rename machine_(u)int_t to mp_(u)int_t.Damien George2014-07-03
| | | | See discussion in issue #50.
* py: Fix check of small-int overflow when parsing ints.Damien George2014-05-28
| | | | Also unifies use of SMALL_INT_FITS macro across parser and runtime.
* Add license header to (almost) all files.Damien George2014-05-03
| | | | | | | 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/.
* py: This time, real proper overflow checking of small int power.Damien George2014-04-04
Previous overflow test was inadequate.
