      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.

      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.

      stmhal: Use polling, not DMA, for 1 byte SPI transfers. · d80174d7
      Damien George authored
      There is an issue sending 1 byte on the SPI bus using DMA, but it only
      occurs when the transmit is done for the first time after initialising
      the SPI and DMA peripherals.  All other cases (sending 2 or more bytes,
      doing send_recv, doing recv first) work okay.  We sidestep this issue by
      using polling (not DMA) for all 1 byte transfers.  This is fine because
      a 1 byte transfer can't be interrupted and doesn't need the benefits of
      DMA (and using polling for this case is more efficient).
      
      Resolves #1456.

      stmhal/dma.c: Modify dma_init() to accept init struct as an argument · c5175526
      blmorris authored
      This removes hard-coded DMA init params from dma_init(), instead defining
      these parameters in a DMA_InitTypeDef struct that gets passed as an
      argument to dma_init()
      This makes dma_init more generic so it can be used for I2S and SD Card,
      which require different initialization parameters.

      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.
