WEBUSB_README.md
View File

@ -62,33 +62,4 @@ The tinyusb examples already include a "WebUSB serial" example.
Basically, this feature was ported into CircuitPython by pulling code snippets out of the
tinyusb example, and putting them where they best belonged in the CircuitPython codebase.
There was one complication:
tinyusb uses C preprocessor macros to define things like USB descriptors.
CircuitPython uses a Python program (tools/gen_usb_descriptor.py) to create USB descriptors (etc.)
using "helper objects" from another repo (adafruit_usb_descriptor). This means some of the example
code had to be adapted to the new programing model, and gen_usb_descriptor gained new command-line
options to control the generated code.
The generated files go into the "build" directory, look for autogen_usb_descriptor.c and
genhdr/autogen_usb_descriptor.h.
Also worth pointing out - the re-use of the CDC connect/disconnect mechanism is not actually part
of the WebUSB standard, it's more of "common idiom". We make use of it here because we need to know
when we should be paying attention to the WebUSB serial interface, and when we should ignore it..
## Possible future work areas
The current code uses the existing Python infrastructure to create the Interface descriptor, but
simply outputs the code snippets from the original tinyusb demo code to create the WEBUSB_URL,
BOS, and MS_OS_20 descriptors. I suppose additional work could be done to add these to the
adafruit_usb_descriptor project, and then gen_usb_descriptor.py could be modified to make use
of them.
Program gen_usb_descriptor.py creates objects for most interface types, regardless of whether or
not they are actually enabled. This increases the size of a generated string table. I made the
new vendor-interface-related code not do this (because some of the ARM platforms would no longer
build), but I did not go back and do this for the other interface types (CDC, MIDI, HID, etc.)
Some FLASH savings are probably possible if this is done.
### TODO: This needs to be reworked for dynamic USB descriptors.

Documenting Parameters
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Although there are different ways to document class and functions definitions in Python,
the following is the prevalent method of documenting parameters
for CircuitPython libraries. When documenting class parameters you should use the
following structure:
.. code-block:: sh
:param param_type param_name: Parameter_description
param_type
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The type of the parameter. This could be among other `int`, `float`, `str` `bool`, etc.
To document an object in the CircuitPython domain, you need to include a ``~`` before the
definition as shown in the following example:
.. code-block:: sh
:param ~busio.I2C i2c_bus: The I2C bus the DS3231 is connected to.
To include references to CircuitPython modules, cookiecutter creates an entry in the
intersphinx_mapping section in the ``conf.py`` file located within the ``docs`` directory.
To add different types outside CircuitPython you need to include them in the intersphinx_mapping::
intersphinx_mapping = {

"BusDevice":("https://circuitpython.readthedocs.io/projects/busdevice/en/latest/", None,),

.. 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.

.. 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.

Supported operators and special sequences are:
``'.'``

Match any character.
``'[...]'``
``[...]``
Match set of characters. Individual characters and ranges are supported,
including negated sets (e.g. ``[^a-c]``).
``'^'``
``^``
Match the start of the string.
``'$'``
``$``
Match the end of the string.
``'?'``
``?``
Match zero or one of the previous sub-pattern.
``'*'``
``*``
Match zero or more of the previous sub-pattern.
``'+'``
``+``
Match one or more of the previous sub-pattern.
``'??'``
``??``
Non-greedy version of ``?``, match zero or one, with the preference
for zero.
``'*?'``
``*?``
Non-greedy version of ``*``, match zero or more, with the preference
for the shortest match.
``'+?'``
``+?``
Non-greedy version of ``+``, match one or more, with the preference
for the shortest match.
``'|'``
``|``
Match either the left-hand side or the right-hand side sub-patterns of
this operator.
``'(...)'``
``(...)``
Grouping. Each group is capturing (a substring it captures can be accessed
with `match.group()` method).
**NOT SUPPORTED**: Counted repetitions (``{m,n}``), more advanced assertions
(``\b``, ``\B``), named groups (``(?P<name>...)``), non-capturing groups
(``(?:...)``), etc.
``\d``
Matches digit. Equivalent to ``[0-9]``.
``\D``
Matches non-digit. Equivalent to ``[^0-9]``.
``\s``
Matches whitespace. Equivalent to ``[ \t-\r]``.
``\S``
Matches non-whitespace. Equivalent to ``[^ \t-\r]``.
``\w``
Matches "word characters" (ASCII only). Equivalent to ``[A-Za-z0-9_]``.
``\W``
Matches non "word characters" (ASCII only). Equivalent to ``[^A-Za-z0-9_]``.
``\``
Escape character. Any other character following the backslash, except
for those listed above, is taken literally. For example, ``\*`` is
equivalent to literal ``*`` (not treated as the ``*`` operator).
Note that ``\r``, ``\n``, etc. are not handled specially, and will be
equivalent to literal letters ``r``, ``n``, etc. Due to this, it's
not recommended to use raw Python strings (``r""``) for regular
expressions. For example, ``r"\r\n"`` when used as the regular
expression is equivalent to ``"rn"``. To match CR character followed
by LF, use ``"\r\n"``.
**NOT SUPPORTED**:
* counted repetitions (``{m,n}``)
* named groups (``(?P<name>...)``)
* non-capturing groups (``(?:...)``)
* more advanced assertions (``\b``, ``\B``)
* special character escapes like ``\r``, ``\n`` - use Python's own escaping
instead

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.

Read up to *n* bytes and return them.
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`.

Limitations
-----------
Accessing non-scalar fields leads to allocation of intermediate objects
1. Accessing non-scalar fields leads to allocation of intermediate objects
to represent them. This means that special care should be taken to
layout a structure which needs to be accessed when memory allocation
is disabled (e.g. from an interrupt). The recommendations are:
* Avoid nested structures. For example, instead of
* Avoid accessing nested structures. For example, instead of
``mcu_registers.peripheral_a.register1``, define separate layout
descriptors for each peripheral, to be accessed as
``peripheral_a.register1``.
* Avoid other non-scalar data, like array. For example, instead of
``peripheral_a.register[0]`` use ``peripheral_a.register0``.
``peripheral_a.register1``. Or just cache a particular peripheral:
``peripheral_a = mcu_registers.peripheral_a``. If a register
consists of multiple bitfields, you would need to cache references
to a particular register: ``reg_a = mcu_registers.peripheral_a.reg_a``.
* Avoid other non-scalar data, like arrays. For example, instead of
``peripheral_a.register[0]`` use ``peripheral_a.register0``. Again,
an alternative is to cache intermediate values, e.g.
``register0 = peripheral_a.register[0]``.
Note that these recommendations will lead to decreased readability
and conciseness of layouts, so they should be used only if the need
to access structure fields without allocation is anticipated (it's
even possible to define 2 parallel layouts - one for normal usage,
and a restricted one to use when memory allocation is prohibited).
2. Range of offsets supported by the ``uctypes`` module is limited.
The exact range supported is considered an implementation detail,
and the general suggestion is to split structure definitions to
cover from a few kilobytes to a few dozen of kilobytes maximum.
In most cases, this is a natural situation anyway, e.g. it doesn't make
sense to define all registers of an MCU (spread over 32-bit address
space) in one structure, but rather a peripheral block by peripheral
block. In some extreme cases, you may need to split a structure in
several parts artificially (e.g. if accessing native data structure
with multi-megabyte array in the middle, though that would be a very
synthetic case).

:mod:`usocket` -- socket module
*******************************
.. include:: ../templates/unsupported_in_circuitpython.inc
.. module:: usocket
:synopsis: socket module
|see_cpython_module| :mod:`cpython:socket`.
This module provides access to the BSD socket interface.
.. admonition:: Difference to CPython
:class: attention
For efficiency and consistency, socket objects in MicroPython implement a ``stream``
(file-like) interface directly. In CPython, you need to convert a socket to
a file-like object using `makefile()` method. This method is still supported
by MicroPython (but is a no-op), so where compatibility with CPython matters,
be sure to use it.
Socket address format(s)
------------------------
The native socket address format of the ``usocket`` module is an opaque data type
returned by `getaddrinfo` function, which must be used to resolve textual address
(including numeric addresses)::
sockaddr = usocket.getaddrinfo('www.micropython.org', 80)[0][-1]
# You must use getaddrinfo() even for numeric addresses
sockaddr = usocket.getaddrinfo('127.0.0.1', 80)[0][-1]
# Now you can use that address
sock.connect(addr)
Using `getaddrinfo` is the most efficient (both in terms of memory and processing
power) and portable way to work with addresses.
However, ``socket`` module (note the difference with native MicroPython
``usocket`` module described here) provides CPython-compatible way to specify
addresses using tuples, as described below.
Summing up:
* Always use `getaddrinfo` when writing portable applications.
* Tuple addresses described below can be used as a shortcut for
quick hacks and interactive use, if your port supports them.
Tuple address format for ``socket`` module:
* IPv4: *(ipv4_address, port)*, where *ipv4_address* is a string with
dot-notation numeric IPv4 address, e.g. ``"8.8.8.8"``, and *port* is and
integer port number in the range 1-65535. Note the domain names are not
accepted as *ipv4_address*, they should be resolved first using
`usocket.getaddrinfo()`.
* IPv6: *(ipv6_address, port, flowinfo, scopeid)*, where *ipv6_address*
is a string with colon-notation numeric IPv6 address, e.g. ``"2001:db8::1"``,
and *port* is an integer port number in the range 1-65535. *flowinfo*
must be 0. *scopeid* is the interface scope identifier for link-local
addresses. Note the domain names are not accepted as *ipv6_address*,
they should be resolved first using `usocket.getaddrinfo()`.
Functions
---------
.. function:: socket(af=AF_INET, type=SOCK_STREAM, proto=IPPROTO_TCP)
Create a new socket using the given address family, socket type and
protocol number. Note that specifying *proto* in most cases is not
required (and not recommended, as some MicroPython ports may omit
``IPPROTO_*`` constants). Instead, *type* argument will select needed
protocol automatically::
# Create STREAM TCP socket
socket(AF_INET, SOCK_STREAM)
# Create DGRAM UDP socket
socket(AF_INET, SOCK_DGRAM)
.. function:: getaddrinfo(host, port)
Translate the host/port argument into a sequence of 5-tuples that contain all the
necessary arguments for creating a socket connected to that service. The list of
5-tuples has following structure::

.. admonition:: Difference to CPython
:class: attention
CPython raises a ``socket.gaierror`` exception (`OSError` subclass) in case
of error in this function. MicroPython doesn't have ``socket.gaierror``
and raises OSError directly. Note that error numbers of `getaddrinfo()`
form a separate namespace and may not match error numbers from
:py:mod:`uerrno` module. To distinguish `getaddrinfo()` errors, they are
represented by negative numbers, whereas standard system errors are
positive numbers (error numbers are accessible using ``e.args[0]`` property
from an exception object). The use of negative values is a provisional
detail which may change in the future.

Constants
---------
.. data:: AF_INET
AF_INET6
Address family types. Availability depends on a particular ``MicroPython port``.
.. data:: SOCK_STREAM
SOCK_DGRAM
Socket types.
.. data:: IPPROTO_UDP
IPPROTO_TCP
IP protocol numbers. Availability depends on a particular ``MicroPython port``.
Note that you don't need to specify these in a call to `usocket.socket()`,
because `SOCK_STREAM` socket type automatically selects `IPPROTO_TCP`, and
`SOCK_DGRAM` - `IPPROTO_UDP`. Thus, the only real use of these constants
is as an argument to `usocket.socket.setsockopt()`.
.. data:: usocket.SOL_*
Socket option levels (an argument to `usocket.socket.setsockopt()`). The exact
inventory depends on a ``MicroPython port``.
.. data:: usocket.SO_*
Socket options (an argument to `usocket.socket.setsockopt()`). The exact
inventory depends on a ``MicroPython port``.
Constants specific to WiPy:
.. data:: IPPROTO_SEC
Special protocol value to create SSL-compatible socket.
class socket
============
Methods
-------
.. method:: socket.close()
Mark the socket closed and release all resources. Once that happens, all future operations
on the socket object will fail. The remote end will receive EOF indication if
supported by protocol.
Sockets are automatically closed when they are garbage-collected, but it is recommended
to `close()` them explicitly as soon you finished working with them.
.. method:: socket.bind(address)
Bind the socket to *address*. The socket must not already be bound.
.. method:: socket.listen([backlog])
Enable a server to accept connections. If *backlog* is specified, it must be at least 0
(if it's lower, it will be set to 0); and specifies the number of unaccepted connections
that the system will allow before refusing new connections. If not specified, a default
reasonable value is chosen.
.. method:: socket.accept()
Accept a connection. The socket must be bound to an address and listening for connections.
The return value is a pair (conn, address) where conn is a new socket object usable to send
and receive data on the connection, and address is the address bound to the socket on the
other end of the connection.
.. method:: socket.connect(address)
Connect to a remote socket at *address*.
.. method:: socket.send(bytes)
Send data to the socket. The socket must be connected to a remote socket.
Returns number of bytes sent, which may be smaller than the length of data
("short write").
.. method:: socket.sendall(bytes)
Send all data to the socket. The socket must be connected to a remote socket.
Unlike `send()`, this method will try to send all of data, by sending data
chunk by chunk consecutively.
The behavior of this method on non-blocking sockets is undefined. Due to this,
on MicroPython, it's recommended to use `write()` method instead, which
has the same "no short writes" policy for blocking sockets, and will return
number of bytes sent on non-blocking sockets.
.. method:: socket.recv(bufsize)
Receive data from the socket. The return value is a bytes object representing the data
received. The maximum amount of data to be received at once is specified by bufsize.
.. method:: socket.sendto(bytes, address)
Send data to the socket. The socket should not be connected to a remote socket, since the
destination socket is specified by *address*.
.. method:: socket.recvfrom(bufsize)
Receive data from the socket. The return value is a pair *(bytes, address)* where *bytes* is a
bytes object representing the data received and *address* is the address of the socket sending
the data.
.. method:: socket.setsockopt(level, optname, value)
Set the value of the given socket option. The needed symbolic constants are defined in the
socket module (SO_* etc.). The *value* can be an integer or a bytes-like object representing
a buffer.
.. method:: socket.settimeout(value)
**Note**: Not every port supports this method, see below.
Set a timeout on blocking socket operations. The value argument can be a nonnegative floating
point number expressing seconds, or None. If a non-zero value is given, subsequent socket operations
will raise an `OSError` exception if the timeout period value has elapsed before the operation has
completed. If zero is given, the socket is put in non-blocking mode. If None is given, the socket
is put in blocking mode.
Not every ``MicroPython port`` supports this method. A more portable and
generic solution is to use `uselect.poll` object. This allows to wait on
multiple objects at the same time (and not just on sockets, but on generic
``stream`` objects which support polling). Example::
# Instead of:
s.settimeout(1.0) # time in seconds
s.read(10) # may timeout
# Use:
poller = uselect.poll()
poller.register(s, uselect.POLLIN)
res = poller.poll(1000) # time in milliseconds
if not res:
# s is still not ready for input, i.e. operation timed out
.. admonition:: Difference to CPython
:class: attention
CPython raises a ``socket.timeout`` exception in case of timeout,
which is an `OSError` subclass. MicroPython raises an OSError directly
instead. If you use ``except OSError:`` to catch the exception,
your code will work both in MicroPython and CPython.
.. method:: socket.setblocking(flag)
Set blocking or non-blocking mode of the socket: if flag is false, the socket is set to non-blocking,
else to blocking mode.
This method is a shorthand for certain `settimeout()` calls:
* ``sock.setblocking(True)`` is equivalent to ``sock.settimeout(None)``
* ``sock.setblocking(False)`` is equivalent to ``sock.settimeout(0)``
.. method:: socket.makefile(mode='rb', buffering=0)
Return a file object associated with the socket. The exact returned type depends on the arguments
given to makefile(). The support is limited to binary modes only ('rb', 'wb', and 'rwb').
CPython's arguments: *encoding*, *errors* and *newline* are not supported.
.. admonition:: Difference to CPython
:class: attention
As MicroPython doesn't support buffered streams, values of *buffering*
parameter is ignored and treated as if it was 0 (unbuffered).
.. admonition:: Difference to CPython
:class: attention
Closing the file object returned by makefile() WILL close the
original socket as well.
.. method:: socket.read([size])
Read up to size bytes from the socket. Return a bytes object. If *size* is not given, it
reads all data available from the socket until EOF; as such the method will not return until
the socket is closed. This function tries to read as much data as
requested (no "short reads"). This may be not possible with
non-blocking socket though, and then less data will be returned.
.. method:: socket.readinto(buf[, nbytes])
Read bytes into the *buf*. If *nbytes* is specified then read at most
that many bytes. Otherwise, read at most *len(buf)* bytes. Just as
`read()`, this method follows "no short reads" policy.
Return value: number of bytes read and stored into *buf*.
.. method:: socket.readline()
Read a line, ending in a newline character.
Return value: the line read.
.. method:: socket.write(buf)
Write the buffer of bytes to the socket. This function will try to
write all data to a socket (no "short writes"). This may be not possible
with a non-blocking socket though, and returned value will be less than
the length of *buf*.
Return value: number of bytes written.
.. exception:: usocket.error
MicroPython does NOT have this exception.
.. admonition:: Difference to CPython
:class: attention
CPython used to have a ``socket.error`` exception which is now deprecated,
and is an alias of `OSError`. In MicroPython, use `OSError` directly.

:mod:`ussl` -- SSL/TLS module
=============================
.. include:: ../templates/unsupported_in_circuitpython.inc
.. module:: ussl
:synopsis: TLS/SSL wrapper for socket objects
|see_cpython_module| :mod:`cpython:ssl`.
This module provides access to Transport Layer Security (previously and
widely known as “Secure Sockets Layer”) encryption and peer authentication
facilities for network sockets, both client-side and server-side.
Functions
---------
.. function:: ussl.wrap_socket(sock, server_side=False, keyfile=None, certfile=None, cert_reqs=CERT_NONE, ca_certs=None)
Takes a ``stream`` *sock* (usually usocket.socket instance of ``SOCK_STREAM`` type),
and returns an instance of ssl.SSLSocket, which wraps the underlying stream in
an SSL context. Returned object has the usual ``stream`` interface methods like
``read()``, ``write()``, etc. In MicroPython, the returned object does not expose
socket interface and methods like ``recv()``, ``send()``. In particular, a
server-side SSL socket should be created from a normal socket returned from
:meth:`~usocket.socket.accept()` on a non-SSL listening server socket.
Depending on the underlying module implementation in a particular
``MicroPython port``, some or all keyword arguments above may be not supported.
.. warning::
Some implementations of ``ussl`` module do NOT validate server certificates,
which makes an SSL connection established prone to man-in-the-middle attacks.
Exceptions
----------
.. data:: ssl.SSLError
This exception does NOT exist. Instead its base class, OSError, is used.
Constants
---------
.. data:: ussl.CERT_NONE
ussl.CERT_OPTIONAL
ussl.CERT_REQUIRED
Supported values for *cert_reqs* parameter.

Glossary
========
.. glossary::
baremetal
A system without a (full-fledged) operating system, for example an
:term:`MCU`-based system. When running on a baremetal system,
MicroPython effectively functions like a small operating system,
running user programs and providing a command interpreter
(:term:`REPL`).
buffer protocol
Any Python object that can be automatically converted into bytes, such
as ``bytes``, ``bytearray``, ``memoryview`` and ``str`` objects, which
all implement the "buffer protocol".
board
Typically this refers to a printed circuit board (PCB) containing a
:term:`microcontroller <MCU>` and supporting components.
MicroPython firmware is typically provided per-board, as the firmware
contains both MCU-specific functionality but also board-level
functionality such as drivers or pin names.
bytecode
A compact representation of a Python program that generated by
compiling the Python source code. This is what the VM actually
executes. Bytecode is typically generated automatically at runtime and
is invisible to the user. Note that while :term:`CPython` and
MicroPython both use bytecode, the format is different. You can also
pre-compile source code offline using the :term:`cross-compiler`.
callee-owned tuple
This is a MicroPython-specific construct where, for efficiency
reasons, some built-in functions or methods may re-use the same
underlying tuple object to return data. This avoids having to allocate
a new tuple for every call, and reduces heap fragmentation. Programs
should not hold references to callee-owned tuples and instead only
extract data from them (or make a copy).
CircuitPython
A variant of MicroPython developed by `Adafruit Industries
<https://circuitpython.org>`_.
CPython
CPython is the reference implementation of the Python programming
language, and the most well-known one. It is, however, one of many
implementations (including Jython, IronPython, PyPy, and MicroPython).
While MicroPython's implementation differs substantially from CPython,
it aims to maintain as much compatibility as possible.
cross-compiler
Also known as ``mpy-cross``. This tool runs on your PC and converts a
:term:`.py file` containing MicroPython code into a :term:`.mpy file`
containing MicroPython bytecode. This means it loads faster (the board
doesn't have to compile the code), and uses less space on flash (the
bytecode is more space efficient).
driver
A MicroPython library that implements support for a particular
component, such as a sensor or display.
FFI
Acronym for Foreign Function Interface. A mechanism used by the
:term:`MicroPython Unix port` to access operating system functionality.
This is not available on :term:`baremetal` ports.
filesystem
Most MicroPython ports and boards provide a filesystem stored in flash
that is available to user code via the standard Python file APIs such
as ``open()``. Some boards also make this internal filesystem
accessible to the host via USB mass-storage.
frozen module
A Python module that has been cross compiled and bundled into the
firmware image. This reduces RAM requirements as the code is executed
directly from flash.
Garbage Collector
A background process that runs in Python (and MicroPython) to reclaim
unused memory in the :term:`heap`.
GPIO
General-purpose input/output. The simplest means to control electrical
signals (commonly referred to as "pins") on a microcontroller. GPIO
typically allows pins to be either input or output, and to set or get
their digital value (logical "0" or "1"). MicroPython abstracts GPIO
access using the :class:`machine.Pin` and :class:`machine.Signal`
classes.
GPIO port
A group of :term:`GPIO` pins, usually based on hardware properties of
these pins (e.g. controllable by the same register).
heap
A region of RAM where MicroPython stores dynamic data. It is managed
automatically by the :term:`Garbage Collector`. Different MCUs and
boards have vastly different amounts of RAM available for the heap, so
this will affect how complex your program can be.
interned string
An optimisation used by MicroPython to improve the efficiency of
working with strings. An interned string is referenced by its (unique)
identity rather than its address and can therefore be quickly compared
just by its identifier. It also means that identical strings can be
de-duplicated in memory. String interning is almost always invisible to
the user.
MCU
Microcontroller. Microcontrollers usually have much less resources
than a desktop, laptop, or phone, but are smaller, cheaper and
require much less power. MicroPython is designed to be small and
optimized enough to run on an average modern microcontroller.
MicroPython port
MicroPython supports different :term:`boards <board>`, RTOSes, and
OSes, and can be relatively easily adapted to new systems. MicroPython
with support for a particular system is called a "port" to that
system. Different ports may have widely different functionality. This
documentation is intended to be a reference of the generic APIs
available across different ports ("MicroPython core"). Note that some
ports may still omit some APIs described here (e.g. due to resource
constraints). Any such differences, and port-specific extensions
beyond the MicroPython core functionality, would be described in the
separate port-specific documentation.
MicroPython Unix port
The unix port is one of the major :term:`MicroPython ports
<MicroPython port>`. It is intended to run on POSIX-compatible
operating systems, like Linux, MacOS, FreeBSD, Solaris, etc. It also
serves as the basis of Windows port. The Unix port is very useful for
quick development and testing of the MicroPython language and
machine-independent features. It can also function in a similar way to
:term:`CPython`'s ``python`` executable.
.mpy file
The output of the :term:`cross-compiler`. A compiled form of a
:term:`.py file` that contains MicroPython bytecode instead of Python
source code.
native
Usually refers to "native code", i.e. machine code for the target
microcontroller (such as ARM Thumb, Xtensa, x86/x64). The ``@native``
decorator can be applied to a MicroPython function to generate native
code instead of bytecode for that function, which will likely be
faster but use more RAM.
port
Usually short for :term:`MicroPython port`, but could also refer to
:term:`GPIO port`.
.py file
A file containing Python source code.
REPL
An acronym for "Read, Eval, Print, Loop". This is the interactive
Python prompt, useful for debugging or testing short snippets of code.
Most MicroPython boards make a REPL available over a UART, and this is
typically accessible on a host PC via USB.
stream
Also known as a "file-like object". An Python object which provides
sequential read-write access to the underlying data. A stream object
implements a corresponding interface, which consists of methods like
``read()``, ``write()``, ``readinto()``, ``seek()``, ``flush()``,
``close()``, etc. A stream is an important concept in MicroPython;
many I/O objects implement the stream interface, and thus can be used
consistently and interchangeably in different contexts. For more
information on streams in MicroPython, see the `io` module.
UART
Acronym for "Universal Asynchronous Receiver/Transmitter". This is a
peripheral that sends data over a pair of pins (TX & RX). Many boards
include a way to make at least one of the UARTs available to a host PC
as a serial port over USB.

* @defgroup WIZnet_socket_APIs 1. WIZnet socket APIs
* @brief WIZnet socket APIs are based on Berkeley socket APIs, thus it has much similar name and interface.
* But there is a little bit of difference.
* @details
* <b> Comparison between WIZnet and Berkeley SOCKET APIs </b>
* <table>
* <tr> <td><b>API</b></td> <td><b>WIZnet</b></td> <td><b>Berkeley</b></td> </tr>
* <tr> <td>socket()</td> <td>O</td> <td>O</td> </tr>
* <tr> <td><b>bind()</b></td> <td>X</td> <td>O</td> </tr>
* <tr> <td><b>listen()</b></td> <td>O</td> <td>O</td> </tr>
* <tr> <td><b>connect()</b></td> <td>O</td> <td>O</td> </tr>
* <tr> <td><b>accept()</b></td> <td>X</td> <td>O</td> </tr>
* <tr> <td><b>recv()</b></td> <td>O</td> <td>O</td> </tr>
* <tr> <td><b>send()</b></td> <td>O</td> <td>O</td> </tr>
* <tr> <td><b>recvfrom()</b></td> <td>O</td> <td>O</td> </tr>
* <tr> <td><b>sendto()</b></td> <td>O</td> <td>O</td> </tr>
* <tr> <td><b>closesocket()</b></td> <td>O<br>close() & disconnect()</td> <td>O</td> </tr>
* </table>
* There are @b bind() and @b accept() functions in @b Berkeley SOCKET API but,
* not in @b WIZnet SOCKET API. Because socket() of WIZnet is not only creating a SOCKET but also binding a local port number,
* and listen() of WIZnet is not only listening to connection request from client but also accepting the connection request. \n
* When you program "TCP SERVER" with Berkeley SOCKET API, you can use only one listen port.
* When the listen SOCKET accepts a connection request from a client, it keeps listening.
* After accepting the connection request, a new SOCKET is created and the new SOCKET is used in communication with the client. \n
* Following figure shows network flow diagram by Berkeley SOCKET API.
* @image html Berkeley_SOCKET.jpg "<Berkeley SOCKET API>"
* But, When you program "TCP SERVER" with WIZnet SOCKET API, you can use as many as 8 listen SOCKET with same port number. \n
* Because there's no accept() in WIZnet SOCKET APIs, when the listen SOCKET accepts a connection request from a client,
* it is changed in order to communicate with the client.
* And the changed SOCKET is not listening any more and is dedicated for communicating with the client. \n
* If there're many listen SOCKET with same listen port number and a client requests a connection,
* the SOCKET which has the smallest SOCKET number accepts the request and is changed as communication SOCKET. \n
* Following figure shows network flow diagram by WIZnet SOCKET API.

//! 1. Explicit type casting in wizchip_bus_readbyte() & wizchip_bus_writebyte()
// Issued by Mathias ClauBen.
//! uint32_t type converts into ptrdiff_t first. And then recoverting it into uint8_t*
//! For remove the warning when pointer type size is not 32bit.
//! If ptrdiff_t doesn't support in your complier, You should must replace ptrdiff_t into your suitable pointer type.
