-Build CircuitPython in a Github-Devcontainer
-============================================
-
-To build CircuitPython within a Github-Devcontainer, you need to perform
-the following steps.
-
-  1. checkout the code to a devcontainer
-
-    - click on the green "<> Code"-button
-    - select the Codespaces-tab
-    - choose "+ new with options..." from the "..."-menu
-    - in the following screen select the branch and then
-    - select ".devcontainer/cortex-m/devcontainer.json" instead
-      of "Default Codespaces configuration"
-    - update region as necessary
-    - finally, click on the green "Create codespace" button
-
-  2. Your codespace is created. Cloning the images is quite fast, but
-     preparing it for CircuitPython-development takes about 10 minutes.
-     Note that this is a one-time task.
-
-  3. During creation, you can run the command
-     `tail -f /workspaces/.codespaces/.persistedshare/creation.log`
-     to see what is going on.
-
-  4. To actually build CircuitPython, run
-
-         cd ports/raspberrypi
-         make -j $(nproc) BOARD=whatever TRANSLATION=xx_XX
-
-     This takes about 2m40s.

+Code Search
+------------
+GitHub doesn't currently support code search on forks. Therefore, CircuitPython doesn't have code search through GitHub because it is a fork of MicroPython. Luckily, `SourceGraph <https://sourcegraph.com/github.com/adafruit/circuitpython>`_ has free code search for public repos like CircuitPython. So, visit `sourcegraph.com/github.com/adafruit/circuitpython <https://sourcegraph.com/github.com/adafruit/circuitpython>`_ to search the CircuitPython codebase online.

+=========================================================
+
+These are libraries and drivers available in separate GitHub repos. They are

+`MicroPython <https://micropython.org>`_.
+
+
+Adafruit CircuitPython Library Bundle
+--------------------------------------
+
+We provide a bundle of all our libraries to ease installation of drivers and
+their dependencies. The bundle is primarily geared to the Adafruit Express line
+of boards which feature a relatively large external flash. With Express boards,
+it's easy to copy them all onto the filesystem. However, if you don't have
+enough space simply copy things over as they are needed.
+
+- The Adafruit bundles are available on GitHub: <https://github.com/adafruit/Adafruit_CircuitPython_Bundle/releases>.
+
+- Documentation for the bundle, which includes links to documentation for all
+  libraries, is available here: <https://circuitpython.readthedocs.io/projects/bundle/en/latest/>.

+CircuitPython Community Library Bundle
+---------------------------------------

-Environment Variables
-=====================
-
-CircuitPython 8.0.0 introduces support for environment variables. Environment
-variables are commonly used to store "secrets" such as Wi-Fi passwords and API
-keys. This method *does not* make them secure. It only separates them from the
-code.
-
-CircuitPython uses a file called ``settings.toml`` at the drive root (no
-folder) as the environment.  User code can access the values from the file
-using `os.getenv()`. It is recommended to save any values used repeatedly in a
-variable because `os.getenv()` will parse the ``settings.toml`` file contents
-on every access.
-
-CircuitPython only supports a subset of the full toml specification, see below
-for more details. The subset is very "Python-like", which is a key reason we
-selected the format.
-
-Due to technical limitations it probably also accepts some files that are
-not valid TOML files; bugs of this nature are subject to change (i.e., be
-fixed) without the usual deprecation period for incompatible changes.
-
-File format example:
-
-.. code-block::
-
-   str_key="Hello world" # with trailing comment
-   int_key = 7
-   unicode_key="œuvre"
-   unicode_key2="\\u0153uvre" # same as above
-   unicode_key3="\\U00000153uvre" # same as above
-   escape_codes="supported, including \\r\\n\\"\\\\"
-   # comment
-   [subtable]
-   subvalue="cannot retrieve this using getenv"
-
-
-Details of the toml language subset
------------------------------------
-
-* The content is required to be in UTF-8 encoding
-* The supported data types are string and integer
-* Only basic strings are supported, not triple-quoted strings
-* Only integers supported by strtol. (no 0o, no 0b, no underscores 1_000, 011
-  is 9, not 11)
-* Only bare keys are supported
-* Duplicate keys are not diagnosed.
-* Comments are supported
-* Only values from the "root table" can be retrieved
-* due to technical limitations, the content of multi-line
-  strings can erroneously be parsed as a value.
-
-CircuitPython behavior
-----------------------
-
-CircuitPython will also read the environment to configure its behavior. Other
-keys are ignored by CircuitPython. Here are the keys it uses:
-
-CIRCUITPY_BLE_NAME
-~~~~~~~~~~~~~~~~~~
-Default BLE name the board advertises as, including for the BLE workflow.
-
-CIRCUITPY_HEAP_START_SIZE
-~~~~~~~~~~~~~~~~~~~~~~~~~
-Sets the initial size of the python heap, allocated from the outer heap. Must be a multiple of 4.
-The default is currently 8192.
-The python heap will grow by doubling and redoubling this initial size until it cannot fit in the outer heap.
-Larger values will reserve more RAM for python use and prevent the supervisor and SDK
-from large allocations of their own.
-Smaller values will likely grow sooner than large start sizes.
-
-CIRCUITPY_PYSTACK_SIZE
-~~~~~~~~~~~~~~~~~~~~~~
-Sets the size of the python stack. Must be a multiple of 4. The default value is currently 1536.
-Increasing the stack reduces the size of the heap available to python code.
-Used to avoid "Pystack exhausted" errors when the code can't be reworked to avoid it.
-
-CIRCUITPY_WEB_API_PASSWORD
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-Password required to make modifications to the board from the Web Workflow.
-
-CIRCUITPY_WEB_API_PORT
-~~~~~~~~~~~~~~~~~~~~~~
-TCP port number used for the web HTTP API. Defaults to 80 when omitted.
-
-CIRCUITPY_WEB_INSTANCE_NAME
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Name the board advertises as for the WEB workflow. Defaults to human readable board name if omitted.
-
-CIRCUITPY_WIFI_PASSWORD
-~~~~~~~~~~~~~~~~~~~~~~~
-Wi-Fi password used to auto connect to CIRCUITPY_WIFI_SSID.
-
-CIRCUITPY_WIFI_SSID
-~~~~~~~~~~~~~~~~~~~
-Wi-Fi SSID to auto-connect to even if user code is not running.

+
+Core functions
+--------------
+
+.. function:: create_task(coro)
+
+    Create a new task from the given coroutine and schedule it to run.
+
+    Returns the corresponding `Task` object.
+
+.. function:: current_task()
+
+    Return the `Task` object associated with the currently running task.
+
+.. function:: run(coro)
+
+    Create a new task from the given coroutine and run it until it completes.
+
+    Returns the value returned by *coro*.
+
+.. function:: sleep(t)
+
+    Sleep for *t* seconds (can be a float).
+
+    This is a coroutine.
+
+.. function:: sleep_ms(t)
+
+    Sleep for *t* milliseconds.
+
+    This is a coroutine, and a MicroPython extension.
+
+Additional functions
+--------------------
+
+.. function:: wait_for(awaitable, timeout)
+
+    Wait for the *awaitable* to complete, but cancel it if it takes longer
+    that *timeout* seconds.  If *awaitable* is not a task then a task will be
+    created from it.
+
+    If a timeout occurs, it cancels the task and raises ``asyncio.TimeoutError``:
+    this should be trapped by the caller.
+
+    Returns the return value of *awaitable*.
+
+    This is a coroutine.
+
+.. function:: wait_for_ms(awaitable, timeout)
+
+    Similar to `wait_for` but *timeout* is an integer in milliseconds.
+
+    This is a coroutine, and a MicroPython extension.
+
+.. function:: gather(*awaitables, return_exceptions=False)
+
+    Run all *awaitables* concurrently.  Any *awaitables* that are not tasks are
+    promoted to tasks.
+
+    Returns a list of return values of all *awaitables*.
+
+    This is a coroutine.
+
+class Task
+----------
+
+.. class:: Task()
+
+    This object wraps a coroutine into a running task.  Tasks can be waited on
+    using ``await task``, which will wait for the task to complete and return
+    the return value of the task.
+
+    Tasks should not be created directly, rather use `create_task` to create them.
+
+.. method:: Task.cancel()
+
+    Cancel the task by injecting a ``CancelledError`` into it.  The task may
+    or may not ignore this exception.
+
+class Event
+-----------
+
+.. class:: Event()
+
+    Create a new event which can be used to synchronise tasks.  Events start
+    in the cleared state.
+
+.. method:: Event.is_set()
+
+    Returns ``True`` if the event is set, ``False`` otherwise.
+
+.. method:: Event.set()
+
+    Set the event.  Any tasks waiting on the event will be scheduled to run.
+
+.. method:: Event.clear()
+
+    Clear the event.
+
+.. method:: Event.wait()
+
+    Wait for the event to be set.  If the event is already set then it returns
+    immediately.
+
+    This is a coroutine.
+
+class Lock
+----------
+
+.. class:: Lock()
+
+    Create a new lock which can be used to coordinate tasks.  Locks start in
+    the unlocked state.
+
+    In addition to the methods below, locks can be used in an ``async with`` statement.
+
+.. method:: Lock.locked()
+
+    Returns ``True`` if the lock is locked, otherwise ``False``.
+
+.. method:: Lock.acquire()
+
+    Wait for the lock to be in the unlocked state and then lock it in an atomic
+    way.  Only one task can acquire the lock at any one time.
+
+    This is a coroutine.
+
+.. method:: Lock.release()
+
+    Release the lock.  If any tasks are waiting on the lock then the next one in the
+    queue is scheduled to run and the lock remains locked.  Otherwise, no tasks are
+    waiting an the lock becomes unlocked.
+
+TCP stream connections
+----------------------
+
+.. function:: open_connection(host, port)
+
+    Open a TCP connection to the given *host* and *port*.  The *host* address will be
+    resolved using `socket.getaddrinfo`, which is currently a blocking call.
+
+    Returns a pair of streams: a reader and a writer stream.
+    Will raise a socket-specific ``OSError`` if the host could not be resolved or if
+    the connection could not be made.
+
+    This is a coroutine.
+
+.. function:: start_server(callback, host, port, backlog=5)
+
+    Start a TCP server on the given *host* and *port*.  The *callback* will be
+    called with incoming, accepted connections, and be passed 2 arguments: reader
+    and writer streams for the connection.
+
+    Returns a `Server` object.
+
+    This is a coroutine.
+
+.. class:: Stream()
+
+    This represents a TCP stream connection.  To minimise code this class implements
+    both a reader and a writer, and both ``StreamReader`` and ``StreamWriter`` alias to
+    this class.
+
+.. method:: Stream.get_extra_info(v)
+
+    Get extra information about the stream, given by *v*.  The valid values for *v* are:
+    ``peername``.
+
+.. method:: Stream.close()
+
+    Close the stream.
+
+.. method:: Stream.wait_closed()
+
+    Wait for the stream to close.
+
+    This is a coroutine.
+
+.. method:: Stream.read(n)
+
+    Read up to *n* bytes and return them.
+
+    This is a coroutine.
+
+.. method:: Stream.readinto(buf)
+
+    Read up to n bytes into *buf* with n being equal to the length of *buf*.
+
+    Return the number of bytes read into *buf*.
+
+    This is a coroutine, and a MicroPython extension.
+
+.. method:: Stream.readexactly(n)
+
+    Read exactly *n* bytes and return them as a bytes object.
+
+    Raises an ``EOFError`` exception if the stream ends before reading *n* bytes.
+
+    This is a coroutine.
+
+.. method:: Stream.readline()
+
+    Read a line and return it.
+
+    This is a coroutine.
+
+.. method:: Stream.write(buf)
+
+    Accumulated *buf* to the output buffer.  The data is only flushed when
+    `Stream.drain` is called.  It is recommended to call `Stream.drain` immediately
+    after calling this function.
+
+.. method:: Stream.drain()
+
+    Drain (write) all buffered output data out to the stream.
+
+    This is a coroutine.
+
+.. class:: Server()
+
+    This represents the server class returned from `start_server`.  It can be used
+    in an ``async with`` statement to close the server upon exit.
+
+.. method:: Server.close()
+
+    Close the server.
+
+.. method:: Server.wait_closed()
+
+    Wait for the server to close.
+
+    This is a coroutine.
+
+Event Loop
+----------
+
+.. function:: get_event_loop()
+
+    Return the event loop used to schedule and run tasks.  See `Loop`.
+
+.. function:: new_event_loop()
+
+    Reset the event loop and return it.
+
+    Note: since MicroPython only has a single event loop this function just
+    resets the loop's state, it does not create a new one.
+
+.. class:: Loop()
+
+    This represents the object which schedules and runs tasks.  It cannot be
+    created, use `get_event_loop` instead.
+
+.. method:: Loop.create_task(coro)
+
+    Create a task from the given *coro* and return the new `Task` object.
+
+.. method:: Loop.run_forever()
+
+    Run the event loop until `stop()` is called.
+
+.. method:: Loop.run_until_complete(awaitable)
+
+    Run the given *awaitable* until it completes.  If *awaitable* is not a task
+    then it will be promoted to one.
+
+.. method:: Loop.stop()
+
+    Stop the event loop.
+
+.. method:: Loop.close()
+
+    Close the event loop.
+
+.. method:: Loop.set_exception_handler(handler)
+
+    Set the exception handler to call when a Task raises an exception that is not
+    caught.  The *handler* should accept two arguments: ``(loop, context)``.
+
+.. method:: Loop.get_exception_handler()
+
+    Get the current exception handler.  Returns the handler, or ``None`` if no
+    custom handler is set.
+
+.. method:: Loop.default_exception_handler(context)
+
+    The default exception handler that is called.
+
+.. method:: Loop.call_exception_handler(context)
+
+    Call the current exception handler.  The argument *context* is passed through and
+    is a dictionary containing keys: ``'message'``, ``'exception'``, ``'future'``.

+:mod:`btree` -- simple BTree database
+=====================================
+
+.. include:: ../templates/unsupported_in_circuitpython.inc
+
+.. module:: btree
+   :synopsis: simple BTree database
+
+The ``btree`` module implements a simple key-value database using external
+storage (disk files, or in general case, a random-access ``stream``). Keys are
+stored sorted in the database, and besides efficient retrieval by a key
+value, a database also supports efficient ordered range scans (retrieval
+of values with the keys in a given range). On the application interface
+side, BTree database work as close a possible to a way standard `dict`
+type works, one notable difference is that both keys and values must
+be `bytes` objects (so, if you want to store objects of other types, you
+need to serialize them to `bytes` first).
+
+The module is based on the well-known BerkelyDB library, version 1.xx.
+
+Example::
+
+    import btree
+
+    # First, we need to open a stream which holds a database
+    # This is usually a file, but can be in-memory database
+    # using io.BytesIO, a raw flash partition, etc.
+    # Oftentimes, you want to create a database file if it doesn't
+    # exist and open if it exists. Idiom below takes care of this.
+    # DO NOT open database with "a+b" access mode.
+    try:
+        f = open("mydb", "r+b")
+    except OSError:
+        f = open("mydb", "w+b")
+
+    # Now open a database itself
+    db = btree.open(f)
+
+    # The keys you add will be sorted internally in the database
+    db[b"3"] = b"three"
+    db[b"1"] = b"one"
+    db[b"2"] = b"two"
+
+    # Assume that any changes are cached in memory unless
+    # explicitly flushed (or database closed). Flush database
+    # at the end of each "transaction".
+    db.flush()
+
+    # Prints b'two'
+    print(db[b"2"])
+
+    # Iterate over sorted keys in the database, starting from b"2"
+    # until the end of the database, returning only values.
+    # Mind that arguments passed to values() method are *key* values.
+    # Prints:
+    #   b'two'

+
+
+Functions
+---------
+
+.. function:: open(stream, *, flags=0, pagesize=0, cachesize=0, minkeypage=0)
+
+   Open a database from a random-access ``stream`` (like an open file). All
+   other parameters are optional and keyword-only, and allow to tweak advanced
+   parameters of the database operation (most users will not need them):
+
+   * *flags* - Currently unused.
+   * *pagesize* - Page size used for the nodes in BTree. Acceptable range
+     is 512-65536. If 0, a port-specific default will be used, optimized for
+     port's memory usage and/or performance.
+   * *cachesize* - Suggested memory cache size in bytes. For a
+     board with enough memory using larger values may improve performance.
+     Cache policy is as follows: entire cache is not allocated at once;
+     instead, accessing a new page in database will allocate a memory buffer
+     for it, until value specified by *cachesize* is reached. Then, these
+     buffers will be managed using LRU (least recently used) policy. More
+     buffers may still be allocated if needed (e.g., if a database contains
+     big keys and/or values). Allocated cache buffers aren't reclaimed.
+   * *minkeypage* - Minimum number of keys to store per page. Default value
+     of 0 equivalent to 2.
+
+   Returns a BTree object, which implements a dictionary protocol (set
+   of methods), and some additional methods described below.
+
+Methods
+-------
+
+.. method:: btree.close()
+
+   Close the database. It's mandatory to close the database at the end of
+   processing, as some unwritten data may be still in the cache. Note that
+   this does not close underlying stream with which the database was opened,
+   it should be closed separately (which is also mandatory to make sure that
+   data flushed from buffer to the underlying storage).
+
+.. method:: btree.flush()
+
+   Flush any data in cache to the underlying stream.
+
+.. method:: btree.__getitem__(key)
+            btree.get(key, default=None, /)
+            btree.__setitem__(key, val)
+            btree.__delitem__(key)
+            btree.__contains__(key)
+
+   Standard dictionary methods.
+
+.. method:: btree.__iter__()
+
+   A BTree object can be iterated over directly (similar to a dictionary)
+   to get access to all keys in order.
+
+.. method:: btree.keys([start_key, [end_key, [flags]]])
+            btree.values([start_key, [end_key, [flags]]])
+            btree.items([start_key, [end_key, [flags]]])
+
+   These methods are similar to standard dictionary methods, but also can
+   take optional parameters to iterate over a key sub-range, instead of
+   the entire database. Note that for all 3 methods, *start_key* and
+   *end_key* arguments represent key values. For example, `values()`
+   method will iterate over values corresponding to they key range
+   given. None values for *start_key* means "from the first key", no
+   *end_key* or its value of None means "until the end of database".
+   By default, range is inclusive of *start_key* and exclusive of
+   *end_key*, you can include *end_key* in iteration by passing *flags*
+   of `btree.INCL`. You can iterate in descending key direction
+   by passing *flags* of `btree.DESC`. The flags values can be ORed
+   together.
+
+Constants
+---------
+
+.. data:: INCL
+
+   A flag for `keys()`, `values()`, `items()` methods to specify that
+   scanning should be inclusive of the end key.
+
+.. data:: DESC
+
+   A flag for `keys()`, `values()`, `items()` methods to specify that
+   scanning should be in descending direction of keys.

+:mod:`framebuf` --- frame buffer manipulation
+=============================================
+
+.. include:: ../templates/unsupported_in_circuitpython.inc
+
+.. module:: framebuf
+   :synopsis: Frame buffer manipulation
+
+This module provides a general frame buffer which can be used to create
+bitmap images, which can then be sent to a display.
+
+class FrameBuffer
+-----------------
+
+The FrameBuffer class provides a pixel buffer which can be drawn upon with
+pixels, lines, rectangles, text and even other FrameBuffer's. It is useful
+when generating output for displays.
+
+For example::
+
+    import framebuf
+
+    # FrameBuffer needs 2 bytes for every RGB565 pixel
+    fbuf = framebuf.FrameBuffer(bytearray(10 * 100 * 2), 10, 100, framebuf.RGB565)
+
+    fbuf.fill(0)
+    fbuf.text('MicroPython!', 0, 0, 0xffff)
+    fbuf.hline(0, 10, 96, 0xffff)
+
+Constructors
+------------
+
+.. class:: FrameBuffer(buffer, width, height, format, stride=width, /)
+
+    Construct a FrameBuffer object.  The parameters are:
+
+        - *buffer* is an object with a buffer protocol which must be large
+          enough to contain every pixel defined by the width, height and
+          format of the FrameBuffer.
+        - *width* is the width of the FrameBuffer in pixels
+        - *height* is the height of the FrameBuffer in pixels
+        - *format* specifies the type of pixel used in the FrameBuffer;
+          permissible values are listed under Constants below. These set the
+          number of bits used to encode a color value and the layout of these
+          bits in *buffer*.
+          Where a color value c is passed to a method, c is a small integer
+          with an encoding that is dependent on the format of the FrameBuffer.
+        - *stride* is the number of pixels between each horizontal line
+          of pixels in the FrameBuffer. This defaults to *width* but may
+          need adjustments when implementing a FrameBuffer within another
+          larger FrameBuffer or screen. The *buffer* size must accommodate
+          an increased step size.
+
+    One must specify valid *buffer*, *width*, *height*, *format* and
+    optionally *stride*.  Invalid *buffer* size or dimensions may lead to
+    unexpected errors.
+
+Drawing primitive shapes
+------------------------
+
+The following methods draw shapes onto the FrameBuffer.
+
+.. method:: FrameBuffer.fill(c)
+
+    Fill the entire FrameBuffer with the specified color.
+
+.. method:: FrameBuffer.pixel(x, y[, c])
+
+    If *c* is not given, get the color value of the specified pixel.
+    If *c* is given, set the specified pixel to the given color.
+
+.. method:: FrameBuffer.hline(x, y, w, c)
+.. method:: FrameBuffer.vline(x, y, h, c)
+.. method:: FrameBuffer.line(x1, y1, x2, y2, c)
+
+    Draw a line from a set of coordinates using the given color and
+    a thickness of 1 pixel. The `line` method draws the line up to
+    a second set of coordinates whereas the `hline` and `vline`
+    methods draw horizontal and vertical lines respectively up to
+    a given length.
+
+.. method:: FrameBuffer.rect(x, y, w, h, c)
+.. method:: FrameBuffer.fill_rect(x, y, w, h, c)
+
+    Draw a rectangle at the given location, size and color. The `rect`
+    method draws only a 1 pixel outline whereas the `fill_rect` method
+    draws both the outline and interior.
+
+Drawing text
+------------
+
+.. method:: FrameBuffer.text(s, x, y[, c])
+
+    Write text to the FrameBuffer using the the coordinates as the upper-left
+    corner of the text. The color of the text can be defined by the optional
+    argument but is otherwise a default value of 1. All characters have
+    dimensions of 8x8 pixels and there is currently no way to change the font.
+
+
+Other methods
+-------------
+
+.. method:: FrameBuffer.scroll(xstep, ystep)
+
+    Shift the contents of the FrameBuffer by the given vector. This may
+    leave a footprint of the previous colors in the FrameBuffer.
+
+.. method:: FrameBuffer.blit(fbuf, x, y, key=-1, palette=None)
+
+    Draw another FrameBuffer on top of the current one at the given coordinates.
+    If *key* is specified then it should be a color integer and the
+    corresponding color will be considered transparent: all pixels with that
+    color value will not be drawn.
+
+    The *palette* argument enables blitting between FrameBuffers with differing
+    formats. Typical usage is to render a monochrome or grayscale glyph/icon to
+    a color display. The *palette* is a FrameBuffer instance whose format is
+    that of the current FrameBuffer. The *palette* height is one pixel and its
+    pixel width is the number of colors in the source FrameBuffer. The *palette*
+    for an N-bit source needs 2**N pixels; the *palette* for a monochrome source
+    would have 2 pixels representing background and foreground colors. The
+    application assigns a color to each pixel in the *palette*. The color of the
+    current pixel will be that of that *palette* pixel whose x position is the
+    color of the corresponding source pixel.
+
+Constants
+---------
+
+.. data:: framebuf.MONO_VLSB
+
+    Monochrome (1-bit) color format
+    This defines a mapping where the bits in a byte are vertically mapped with
+    bit 0 being nearest the top of the screen. Consequently each byte occupies
+    8 vertical pixels. Subsequent bytes appear at successive horizontal
+    locations until the rightmost edge is reached. Further bytes are rendered
+    at locations starting at the leftmost edge, 8 pixels lower.
+
+.. data:: framebuf.MONO_HLSB

+
+   If *level* is given then this function sets the optimisation level for subsequent

+   optimisation level.
+
+   The optimisation level controls the following compilation features:

+   - Assertions: at level 0 assertion statements are enabled and compiled into the
+     bytecode; at levels 1 and higher assertions are not compiled.
+   - Built-in ``__debug__`` variable: at level 0 this variable expands to ``True``;
+     at levels 1 and higher it expands to ``False``.
+   - Source-code line numbers: at levels 0, 1 and 2 source-code line number are

+

+
+.. function:: stack_use()

+
+.. function:: heap_lock()
+.. function:: heap_unlock()
+.. function:: heap_locked()
+
+   Lock or unlock the heap.  When locked no memory allocation can occur and a
+   `MemoryError` will be raised if any heap allocation is attempted.
+   `heap_locked()` returns a true value if the heap is currently locked.
+
+   These functions can be nested, ie `heap_lock()` can be called multiple times
+   in a row and the lock-depth will increase, and then `heap_unlock()` must be
+   called the same number of times to make the heap available again.
+
+   Both `heap_unlock()` and `heap_locked()` return the current lock depth
+   (after unlocking for the former) as a non-negative integer, with 0 meaning
+   the heap is not locked.
+
+   If the REPL becomes active with the heap locked then it will be forcefully
+   unlocked.
+
+   Note: `heap_locked()` is not enabled on most ports by default,
+   requires ``MICROPY_PY_MICROPYTHON_HEAP_LOCKED``.
+
+.. function:: kbd_intr(chr)
+
+   Set the character that will raise a `KeyboardInterrupt` exception.  By
+   default this is set to 3 during script execution, corresponding to Ctrl-C.
+   Passing -1 to this function will disable capture of Ctrl-C, and passing 3
+   will restore it.
+
+   This function can be used to prevent the capturing of Ctrl-C on the
+   incoming stream of characters that is usually used for the REPL, in case
+   that stream is used for other purposes.
+
+.. function:: schedule(func, arg)
+
+   Schedule the function *func* to be executed "very soon".  The function
+   is passed the value *arg* as its single argument.  "Very soon" means that
+   the MicroPython runtime will do its best to execute the function at the
+   earliest possible time, given that it is also trying to be efficient, and
+   that the following conditions hold:
+
+   - A scheduled function will never preempt another scheduled function.
+   - Scheduled functions are always executed "between opcodes" which means
+     that all fundamental Python operations (such as appending to a list)
+     are guaranteed to be atomic.
+   - A given port may define "critical regions" within which scheduled
+     functions will never be executed.  Functions may be scheduled within
+     a critical region but they will not be executed until that region
+     is exited.  An example of a critical region is a preempting interrupt
+     handler (an IRQ).
+
+   A use for this function is to schedule a callback from a preempting IRQ.
+   Such an IRQ puts restrictions on the code that runs in the IRQ (for example
+   the heap may be locked) and scheduling a function to call later will lift
+   those restrictions.
+
+   Note: If `schedule()` is called from a preempting IRQ, when memory
+   allocation is not allowed and the callback to be passed to `schedule()` is
+   a bound method, passing this directly will fail. This is because creating a
+   reference to a bound method causes memory allocation. A solution is to
+   create a reference to the method in the class constructor and to pass that
+   reference to `schedule()`.
+
+   There is a finite queue to hold the scheduled functions and `schedule()`
+   will raise a `RuntimeError` if the queue is full.

-# Workflows
-
-Workflows are the process used to 1) manipulate files on the CircuitPython device and 2) interact
-with the serial connection to CircuitPython. The serial connection is usually used to access the
-REPL.
-
-Starting with CircuitPython 3.x we moved to a USB-only workflow. Prior to that, we used the serial
-connection alone to do the whole workflow. In CircuitPython 7.x, a BLE workflow was added with the
-advantage of working with mobile devices. CircuitPython 8.x added a web workflow that works over the
-local network (usually Wi-Fi) and a web browser. Other clients can also use the Web REST API. Boards
-should clearly document which workflows are supported.
-
-Code for workflows lives in `supervisor/shared`.
-
-The workflow APIs are documented here.
-
-## USB
-
-These USB interfaces are enabled by default on boards with USB support. They are usable once the
-device has been plugged into a host.
-
-### CIRCUITPY drive
-CircuitPython exposes a standard mass storage (MSC) interface to enable file manipulation over a
-standard interface. This interface works underneath the file system at the block level so using it
-excludes other types of workflows from manipulating the file system at the same time.
-
-### CDC serial
-CircuitPython exposes one CDC USB interface for CircuitPython serial. This is a standard serial
-USB interface.
-
-TODO: Document how it designates itself from the user CDC.
-
-Setting baudrate 1200 and disconnecting will reboot into a bootloader. (Used by Arduino to trigger
-a reset into bootloader.)
-
-## BLE
-
-The BLE workflow is enabled for nRF boards. By default, to prevent malicious access, it is disabled.
-To connect to the BLE workflow, press the reset button while the status led blinks blue quickly
-after the safe mode blinks. The board will restart and broadcast the file transfer service UUID
-(`0xfebb`) along with the board's [Creation IDs](https://github.com/creationid/creators). This
-public broadcast is done at a lower transmit level so the devices must be closer. On connection, the
-device will need to pair and bond. Once bonded, the device will broadcast whenever disconnected
-using a rotating key rather than a static one. Non-bonded devices won't be able to resolve it. After
-connection, the central device can discover two default services. One for file transfer and one for
-CircuitPython specifically that includes serial characteristics.
-
-To change the default BLE advertising name without (or before) running user code, the desired name
-can be put in the `settings.toml` file. The key is `CIRCUITPY_BLE_NAME`. It's limited to approximately
-30 characters depending on the port's settings and will be truncated if longer.
-
-### File Transfer API
-
-CircuitPython uses [an open File Transfer API](https://github.com/adafruit/Adafruit_CircuitPython_BLE_File_Transfer)
-to enable file system access.
-
-### CircuitPython Service
-
-The base UUID for the CircuitPython service is `ADAFXXXX-4369-7263-7569-7450794686e`. The `XXXX` is
-replaced by the four specific digits below. The service itself is `0001`.
-
-#### TX - `0002` / RX - `0003`
-
-These characteristic work just like the Nordic Uart Service (NUS) but have different UUIDs to prevent
-conflicts with user created NUS services.
-
-#### Version - `0100`
-Read-only characteristic that returns the UTF-8 encoded version string.
-
-## Web
-If the keys `CIRCUITPY_WIFI_SSID` and `CIRCUITPY_WIFI_PASSWORD` are set in `settings.toml`,
-CircuitPython will automatically connect to the given Wi-Fi network on boot and upon reload.
-
-If `CIRCUITPY_WEB_API_PASSWORD` is also set, the web workflow will also start.
-The web workflow will only be enabled if the Wi-Fi connection succeeds upon boot.
-
-The webserver is on port 80 unless overridden by `CIRCUITPY_WEB_API_PORT`. It also enables MDNS.
-The name of the board as advertised to the network can be overridden by `CIRCUITPY_WEB_INSTANCE_NAME`.
-
-Here is an example `/settings.toml`:
-
-```bash
-# To auto-connect to Wi-Fi
-CIRCUITPY_WIFI_SSID="scottswifi"
-CIRCUITPY_WIFI_PASSWORD="secretpassword"
-
-# To enable the the webserver. Change this too!
-# Leave the User field blank in the browser.
-CIRCUITPY_WEB_API_PASSWORD="passw0rd"
-
-CIRCUITPY_WEB_API_PORT=80
-CIRCUITPY_WEB_INSTANCE_NAME=""
-```
-
-MDNS is used to resolve [`circuitpython.local`](http://circuitpython.local) to a device specific
-hostname of the form `cpy-XXXXXX.local`. The `XXXXXX` is based on network MAC address. The device
-also provides the MDNS service with service type `_circuitpython` and protocol `_tcp`.
-
-Since port 80 (or the port assigned to `CIRCUITPY_WEB_API_PORT`) is used for web workflow, the `mdns`
-[module](https://docs.circuitpython.org/en/latest/shared-bindings/mdns/index.html#mdns.Server.advertise_service)
-can't advertise an additional service on that port.
-
-### HTTP
-The web server is HTTP 1.1 and may use chunked responses so that it doesn't need to precompute
-content length.
-
-The API generally consists of an HTTP method such as GET or PUT and a path. Requests and responses
-also have headers. Responses will contain a status code and status text such as `404 Not Found`.
-This API tries to use standard status codes to encode the status of the various operations. The
-[Mozilla Developer Network HTTP docs](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP)
-are a great reference.
-
-#### Examples
-The examples use `curl`, a common command line program for issuing HTTP requests. The examples below
-use `circuitpython.local` as the easiest way to work. If you have multiple active devices, you'll
-want to use the specific `cpy-XXXXXX.local` version.
-
-The examples also use `passw0rd` as the password placeholder. Replace it with your password before
-running the example.
-
-### `/`
-The root welcome page links to the file system page and also displays other CircuitPython devices
-found using MDNS service discovery. This allows web browsers to find other devices from one. (All
-devices will respond to `circuitpython.local` so the device redirected to may vary.)
-
-### CORS
-The web server will allow requests from `cpy-XXXXXX.local`, `127.0.0.1`, the device's IP and
-`code.circuitpython.org`. (`circuitpython.local` requests will be redirected to `cpy-XXXXXX.local`.)
-
-### File REST API
-All file system related APIs are protected by HTTP basic authentication. It is *NOT* secure but will
-hopefully prevent some griefing in shared settings. The password is sent unencrypted so do not reuse
-a password with something important. The user field is left blank.
-
-The password is taken from `settings.toml` with the key `CIRCUITPY_WEB_API_PASSWORD`. If this is unset, the
-server will respond with `403 Forbidden`. When a password is set, but not provided in a request, it
-will respond `401 Unauthorized`.
-
-#### `/fs/`
-
-The `/fs/` page will respond with a directory browsing HTML once authenticated. This page is always
-gzipped. If the `Accept: application/json` header is provided, then the JSON representation of the
-root will be returned.
-
-##### OPTIONS
-When requested with the `OPTIONS` method, the server will respond with CORS related headers. Most
-aren't needed for API use. They are there for the web browser.
-
-* `Access-Control-Allow-Methods` - Varies with USB state. `GET, OPTIONS` when USB is active. `GET, OPTIONS, PUT, DELETE, MOVE` otherwise.
-
-Example:
-
-```sh
-curl -v -u :passw0rd -X OPTIONS -L --location-trusted http://circuitpython.local/fs/
-```
-
-#### `/fs/<directory path>/`
-Directory paths must end with a /. Otherwise, the path is assumed to be a file.
-
-##### GET
-Returns a JSON representation of the directory.
-
-* `200 OK` - Directory exists and JSON returned
-* `401 Unauthorized` - Incorrect password
-* `403 Forbidden` - No `CIRCUITPY_WEB_API_PASSWORD` set

-
-This is an authenticated endpoint in both modes.
-
-#### `/cp/version.json`

-	"port": 80,
-	"ip": "192.168.1.94"
-}
-```
-
-#### `/code/`
-
-The `/code/` page returns a small static html page that will pull in and load the full code editor from
-[code.circuitpython.org](https://code.circuitpython.org) for a full code editor experience. Because most
-of the resources reside online instead of the device, an active internet connection is required.
-
-### Static files
-
-* `/favicon.ico` - Blinka
-* `/directory.js` - JavaScript for `/fs/`
-* `/welcome.js` - JavaScript for `/`
-
-### WebSocket
-
-The CircuitPython serial interactions are available over a WebSocket. A WebSocket begins as a
-special HTTP request that gets upgraded to a WebSocket. Authentication happens before upgrading.
-
-WebSockets are *not* bare sockets once upgraded. Instead they have their own framing format for data.
-CircuitPython can handle PING and CLOSE opcodes. All others are treated as TEXT. Data to
-CircuitPython is expected to be masked UTF-8, as the spec requires. Data from CircuitPython to the
-client is unmasked. It is also unbuffered so the client will get a variety of frame sizes.
-
-Only one WebSocket at a time is supported.
-
-### Versions
-
-* `1` - Initial version.
-* `2` - Added `/cp/diskinfo.json`.
-* `3` - Changed `/cp/diskinfo.json` to return a list in preparation for multi-disk support.

-# Dynamic Native Modules
-
-Dynamic Native Modules are .mpy files that contain native machine code from a
-language other than Python. For more info see [the documentation]
-(https://docs.micropython.org/en/latest/develop/natmod.html).
-
-This should not be confused with [User C Modules]
-(https://docs.micropython.org/en/latest/develop/cmodules.html) which are a
-mechanism to add additional out-of-tree modules into the firmware build.
-
-## Examples
-
-This directory contains several examples of writing dynamic native modules, in
-two main categories:
-
-1.  Feature examples.
-
-    * `features0` - A module containing a single "factorial" function which
-      demonstrates working with integers.
-
-    * `features1` - A module that demonstrates some common tasks:
-        - defining simple functions exposed to Python
-        - defining local, helper C functions
-        - defining constant integers and strings exposed to Python
-        - getting and creating integer objects
-        - creating Python lists
-        - raising exceptions
-        - allocating memory
-        - BSS and constant data (rodata)
-        - relocated pointers in rodata
-
-    * `features2` - This is a hybrid module containing both Python and C code,
-      and additionally the C code is spread over multiple files. It also
-      demonstrates using floating point (only when the target supports
-      hardware floating point).
-
-    * `features3` - A module that shows how to use types, constant objects,
-      and creating dictionary instances.
-
-    * `features4` - A module that demonstrates how to define a class.
-
-2.  Dynamic version of existing built-ins.
-
-    This provides a way to add missing functionality to firmware that doesn't
-    include certain built-in modules. See the `heapq`, `random`, `re`,
-    `deflate`, `btree`, and `framebuf` directories.
-
-    So for example, if your firmware was compiled with `MICROPY_PY_FRAMEBUF`
-    disabled (e.g. to save flash space), then it would not include the
-    `framebuf` module. The `framebuf` native module provides a way to add the
-    `framebuf` module dynamically.
-
-    The way these work is they define a dynamic native module which
-    `#include`'s the original module and then does the necessary
-    initialisation of the module's globals dict.
-
-## Build instructions
-
-To compile an example, you need to have the same toolchain available as
-required for your target port. e.g. `arm-none-eabi-gcc` for any ARM Cortex M
-target. See the port instructions for details.
-
-You also need to have the `pyelftools` Python package available, either via
-your system package manager or installed from PyPI in a virtual environment
-with `pip`.
-
-Each example provides a Makefile. You should specify the `ARCH` argument to
-make (one of x86, x64, armv6m, armv7m, xtensa, xtensawin):
-
-```
-$ cd features0
-$ make ARCH=armv7m
-$ mpremote cp features0.mpy :
