      stmhal: Add PWM capability for LED(3) and LED(4) on pyboards. · a8a4b01a
      Damien George authored
      USB CDC no longer needs TIM3 (which was originally used for LED(4) PWM)
      and so TIM3 has been freed for general purpose use by the user.  Hence
      LED(4) lost its PWM capabilities.
      
      This patch reinstates the PWM capabilities using a semi-generic piece
      of code which allows to configure a timer and PWM channel to use for any
      LED.  But the PWM capability is only configured if the LED is set to an
      intensity between 1 and 254 (ie only when needed).  In that case the
      relevant timer is configured for PWM.  It's up to the user to make sure
      the timers are not used if PWM is active.
      
      This patch also makes sure that PWM LEDs are turned off using standard
      GPIO when calling led.off() or led.intensity(0), instead of just setting
      the PWM counter to zero.

      stmhal: Make TIM3 available for use by the user. · ea89b80f
      Damien George authored
      TIM3 is no longer used by USB CDC for triggering outgoing data, so we
      can now make it available to the user.
      
      PWM fading on LED(4) is now gone, but will be reinstated in a new way.

      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.

      all: Add py/mphal.h and use it in all ports. · 731f3592
      Damien George authored
      py/mphal.h contains declarations for generic mp_hal_XXX functions, such
      as stdio and delay/ticks, which ports should provide definitions for.  A
      port will also provide mphalport.h with further HAL declarations.

      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.

      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.

      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.

      stmhal: Unify naming of HW config; make SD detect configurable. · 09d20778
      Damien George authored
      All board config macros now begin with MICROPY_HW_.
      
      Renamed PYBv10 to PYBV10, since macros should be all uppercase.
      
      Made SDCARD_DETECT configurable in mpconfigport.h, so that the SD
      detect pin can be easily configured.

      stmhal: Implement selector for USB device mode; improve boot up. · 038df431
      Damien George authored
      Can now choose at boot up whether the USB device is CDC+MSC or CDC+HID.
      Choice is made by an option in boot.py, with default being CDC+MSC.
      HID+MSC is not currently supported, but should be easy to implement.
      
      Boot up now has ability to change the reset mode: hold down USR switch
      while booting and LEDs will count from 1 to 7 to indicate the boot mode.
      Release USR when correct mode is selected.  Current modes are 1 (normal
      boot), 2 (safe mode), 3 (reset FS mode).

      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.
