      stmhal: Disable MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE. · ad33e246
      Damien George authored
      It uses RAM and on pyboard we are generally tight on RAM, so disable
      this optimisation for general builds.  If users need the speed then
      they can build their own version.  Maybe in the future we can have
      different versions of pyboard firmware built with different tradeoffs.

      stmhal: Collect all root pointers together in 1 place. · 3b51b3e9
      Damien George authored
      A GC in stmhal port now only scans true root pointers, not entire BSS.
      This reduces base GC time from 1700ms to 900ms.

      py: Add option to cache map lookup results in bytecode. · 7ee91cf8
      Damien George authored
      This is a simple optimisation inspired by JITing technology: we cache in
      the bytecode (using 1 byte) the offset of the last successful lookup in
      a map. This allows us next time round to check in that location in the
      hash table (mp_map_t) for the desired entry, and if it's there use that
      entry straight away.  Otherwise fallback to a normal map lookup.
      Works for LOAD_NAME, LOAD_GLOBAL, LOAD_ATTR and STORE_ATTR opcodes.
      On a few tests it gives >90% cache hit and greatly improves speed of
      Disabled by default.  Enabled for unix and stmhal ports.

      py: Allow builtins to be overridden. · 78d702c3
      Damien George authored
      This patch adds a configuration option (MICROPY_CAN_OVERRIDE_BUILTINS)
      which, when enabled, allows to override all names within the builtins
      module.  A builtins override dict is created the first time the user
      assigns to a name in the builtins model, and then that dict is searched
      first on subsequent lookups.  Note that this implementation doesn't
      allow deleting of names.
      This patch also does some refactoring of builtins code, creating the
      modbuiltins.c file.
      Addresses issue #959.

      stmhal: Add ioctl to USB_VCP object, so it works with select. · 9a41b32b
      Damien George authored
      This patch also enables non-blocking streams on stmhal port.
      One can now make a USB-UART pass-through function:
      def pass_through(usb, uart):
          while True:
              select.select([usb, uart], [], [])
              if usb.any():
              if uart.any():
      pass_through(pyb.USB_VCP(), pyb.UART(1, 9600))

      stmhal: Add network and usocket module. · 3a1c4c5b
      Damien George authored
      As per issue #876, the network module is used to configure NICs
      (hardware modules) and configure routing.  The usocket module is
      supposed to implement the normal Python socket module and selects the
      underlying NIC using routing logic.
      Right now the routing logic is brain dead: first-initialised,
      first-used.  And the routing table is just a list of registered NICs.
      cc3k and wiznet5k work, but not at the same time due to C name clashes
      (to be fixed).
      Note that the usocket module has alias socket, so that one can import
      socket and it works as normal.  But you can also override socket with
      your own module, using usocket at the backend.

      stmhal: Add wiznet5k module, to control WIZnet ethernet adaptor. · bcf041f1
      Damien George authored
      Allows to create socket objects that support TCP and UDP in server and
      client mode.  Interface is very close to standard Python socket class,
      except bind and accept do not work the same (due to hardware not
      supporting them in the usual way).
      Not compiled by default.  To compile this module, use:
      make MICROPY_PY_WIZNET5K=1

      stmhal: Make enable_irq and disable_irq inline functions. · e5cbb703
      Damien George authored
      These functions are generally 1 machine instruction, and are used in
      critical code, so makes sense to have them inline.
      Also leave these functions uninverted (ie 0 means enable, 1 means
      disable) and provide macro constants if you really need to distinguish
      the states.  This makes for smaller code as well (combined with
      Applied to teensy port as well.

      Add support for storing args during an exception raised by an irq. · 5b7fd20f
      Dave Hylands authored
      The user code should call micropython.alloc_emergency_exception_buf(size)
      where size is the size of the buffer used to print the argument
      passed to the exception.
      With the test code from #732, and a call to
      micropython.alloc_emergenncy_exception_buf(100) the following error is
      now printed:
      >>> import heartbeat_irq
      Uncaught exception in Timer(4) interrupt handler
      Traceback (most recent call last):
        File "0://heartbeat_irq.py", line 14, in heartbeat_cb
      NameError: name 'led' is not defined

      py: Add stream reading of n unicode chars; unicode support by default. · 1694bc73
      Damien George authored
      With unicode enabled, this patch allows reading a fixed number of
      characters from text-mode streams; eg file.read(5) will read 5 unicode
      chars, which can made of more than 5 bytes.
      For an ASCII stream (ie no chars > 127) it only needs to do 1 read.  If
      there are lots of non-ASCII chars in a stream, then it needs multiple
      reads of the underlying object.
      Adds a new test for this case.  Enables unicode support by default on
      unix and stmhal ports.
