+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.

 -  Adds a safe mode that does not run user code after a hard crash or brown out. This makes it
    possible to fix code that causes nasty crashes by making it available through mass storage after
    the crash. A reset (the button) is needed after it's fixed to get back into normal mode.
--  Safe mode may be handled programmatically by providing a ``safemode.py``.
-   ``safemode.py`` is run if the board has reset due to entering safe mode, unless the safe mode

-   USB is not available so nothing can be printed.
-   ``safemode.py`` can determine why the safe mode occurred
-   using ``supervisor.runtime.safe_mode_reason``, and take appropriate action. For instance,
-   if a hard crash occurred, ``safemode.py`` may do a ``microcontroller.reset()``
-   to automatically restart despite the crash.
-   If the battery is low, but is being charged, ``safemode.py`` may put the board in deep sleep
-   for a while. Or it may simply reset, and have ``code.py`` check the voltage and do the sleep.

+: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'
+    #   b'three'
+    for word in db.values(b"2"):
+        print(word)
+
+    del db[b"2"]
+
+    # No longer true, prints False
+    print(b"2" in db)
+
+    # Prints:
+    #  b"1"
+    #  b"3"
+    for key in db:
+        print(key)
+
+    db.close()
+
+    # Don't forget to close the underlying stream!
+    f.close()
+
+
+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(100 * 10 * 2), 100, 10, framebuf.RGB565)
+
+    fbuf.fill(0)
+    fbuf.text('MicroPython!', 0, 0, 0xffff)
+    fbuf.hline(0, 9, 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
+
+    Monochrome (1-bit) color format
+    This defines a mapping where the bits in a byte are horizontally mapped.
+    Each byte occupies 8 horizontal pixels with bit 7 being the leftmost.

+    rightmost edge is reached. Further bytes are rendered on the next row, one
+    pixel lower.

+   `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

+   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.

-# 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 :
