      py: Overhaul and simplify printf/pfenv mechanism. · 7f9d1d6a
      Damien George authored
      Previous to this patch the printing mechanism was a bit of a tangled
      mess.  This patch attempts to consolidate printing into one interface.
      
      All (non-debug) printing now uses the mp_print* family of functions,
      mainly mp_printf.  All these functions take an mp_print_t structure as
      their first argument, and this structure defines the printing backend
      through the "print_strn" function of said structure.
      
      Printing from the uPy core can reach the platform-defined print code via
      two paths: either through mp_sys_stdout_obj (defined pert port) in
      conjunction with mp_stream_write; or through the mp_plat_print structure
      which uses the MP_PLAT_PRINT_STRN macro to define how string are printed
      on the platform.  The former is only used when MICROPY_PY_IO is defined.
      
      With this new scheme printing is generally more efficient (less layers
      to go through, less arguments to pass), and, given an mp_print_t*
      structure, one can call mp_print_str for efficiency instead of
      mp_printf("%s", ...).  Code size is also reduced by around 200 bytes on
      Thumb2 archs.

      Fix timer overflow code. · 39296b40
      Dave Hylands authored
      Teensy doesn't need to worry about overflows since all of
      its timers are only 16-bit.
      
      For PWM, the pulse width needs to be able to vary from 0..period+1
      (pulse-width == period+1 corresponds to 100% PWM)
      
      I couldn't test the 0xffffffff cases since we can't currently get a
      period that big in python. With a prescaler of 0, that corresponds
      to a freq of 0.039 (i.e. cycle every 25.56 seconds), and we can't
      set that using freq or period.
      
      I also tested both stmhal and teensy with floats disabled, which
      required a few other code changes to compile.

      Add license header to (almost) all files. · 04b9147e
      Damien George authored
      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/.

      stmhal: Add documentation in comments, and script to generate HTML. · 8d09640b
      Damien George authored
      Decided to write own script to pull documentation from comments in C code.
      Style for writing auto generated documentation is: start line with ///
      and then use standard markdown to write the comment.  Keywords
      recognised by the scraper begin with backslash.  See code for examples.
      
      Running: python gendoc.py modpyb.c accel.c adc.c dac.c extint.c i2c.c
      led.c pin.c rng.c servo.c spi.c uart.c usrsw.c, will generate a HTML
      structure in gendoc-out/.
      
      gendoc.py is crude but functional.  Needed something quick, and this was
      it.

      stmhal: Update ADC, DAC and I2C objects to use new buffer protocol. · 38ae014e
      Damien George authored
      Main reason for expanding buffer protocol API was to support writes to a
      buffer in ADC module (see read_timed).  With this change you can now
      create an array of arbitrary type and ADC.read_timed will store into
      that array in the correct format (byte, int, float).  I wonder though if
      all these changes were really worth it to support just this function.
      Hopefully this enhanced buffer protocol API (with typecode specified)
      will be used elsewhere.

      stmhal: Big cleanup; merge gpio into Pin; make names consistent. · c66d86c5
      Damien George authored
      This is an attempt to clean up the Micro Python API on the pyboard.
      Gpio functionality is now in the Pin object, which seems more natural.
      Constants for MODE and PULL are now in pyb.Pin.  Names of some
      classes have been adjusted to conform to CamelCase.  Other
      miscellaneous changes and clean up here and there.

      Merge map.h into obj.h. · df6567e6
      Damien George authored
      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.

      Rename rt_* to mp_*. · d17926db
      Damien George authored
      Mostly just a global search and replace.  Except rt_is_true which
      becomes mp_obj_is_true.
      
      Still would like to tidy up some of the names, but this will do for now.

      Remove mp_obj_type_t.methods entry and use .locals_dict instead. · 9b196cdd
      Damien George authored
      Originally, .methods was used for methods in a ROM class, and
      locals_dict for methods in a user-created class.  That distinction is
      unnecessary, and we can use locals_dict for ROM classes now that we have
      ROMable maps.
      
      This removes an entry in the bloated mp_obj_type_t struct, saving a word
      for each ROM object and each RAM object.  ROM objects that have a
      methods table (now a locals_dict) need an extra word in total (removed
      the methods pointer (1 word), no longer need the sentinel (2 words), but
      now need an mp_obj_dict_t wrapper (4 words)).  But RAM objects save a
      word because they never used the methods entry.
      
      Overall the ROM usage is down by a few hundred bytes, and RAM usage is
      down 1 word per user-defined type/class.
      
      There is less code (no need to check 2 tables), and now consistent with
      the way ROM modules have their tables initialised.
      
      Efficiency is very close to equivaluent.
