      stmhal: L4: Adapt DMA to be able to support STM32L4 MCU series. · e64032d6
      Tobias Badertscher authored
      The main thing is to change the DMA code in a way that the structure
      DMA_Stream_TypeDef (which is similar to DMA_Channel_TypeDef on stm32l4)
      is no longer used outside of dma.c, as this structure only exists for the
      F4 series.  Therefore I introduced a new structure (dma_descr_t) which
      handles all DMA specific stuff for configuration.  Further the periphery
      (spi, i2c, sdcard, dac) does not need to know the internals of the dma.

      py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*. · 5b3f0b7f
      Damien George authored
      The first argument to the type.make_new method is naturally a uPy type,
      and all uses of this argument cast it directly to a pointer to a type
      structure.  So it makes sense to just have it a pointer to a type from
      the very beginning (and a const pointer at that).  This patch makes
      such a change, and removes all unnecessary casting to/from mp_obj_t.

      stmhal: Allow to set bits resolution for DAC; 8 is default, can have 12. · b5c43be1
      Damien George authored
      This patch allows to configure the DAC resolution in the constructor and
      in the init function, eg:
      
      dac = DAC(1, bits=12).
      
      The default resolution is 8 bits for backwards compatibility.  The bits
      sets the maximum value accepted by write and write_timed methods, being
      2**bits - 1.
      
      When using write_timed with 12-bit resolution, the input buffer is
      treated as an unsigned half-word array, typecode 'H'.
      
      See PR #1130 for discussion.

      stmhal: Update STM32Cube F4 HAL driver to V1.3.0. · 3ef91134
      Damien George authored
      This patch updates ST's HAL to the latest version, V1.3.0, dated 19 June
      2014.  Files were copied verbatim from the ST package.  Only change was
      to suppress compiler warning of unused variables in 4 places.
      
      A lot of the changes from ST are cosmetic: comments and white space.
      Some small code changes here and there, and addition of F411 header.
      
      Main code change is how SysTick interrupt is set: it now has a
      configuration variable to set the priority, so we no longer need to work
      around this (originall in system_stm32f4xx.c).

      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.

      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.
