Additional CircuitPython Libraries and Drivers on GitHub
|
||||
=========================================================
|
||||
|
||||
These are libraries and drivers available in separate GitHub repos. They are
|
||||
designed for use with CircuitPython and may or may not work with
|
||||
`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
|
||||
---------------------------------------
|
||||
|
||||
This bundle contains non-Adafruit sponsored libraries, that are written and submitted
|
||||
by members of the community.
|
||||
|
||||
- The Community bundles are available on GitHub: <https://github.com/adafruit/CircuitPython_Community_Bundle/releases>.
|
||||
|
||||
- Documentation is not available on ReadTheDocs at this time. See each library for any
|
||||
included documentation.

Adafruit CircuitPython Libraries
|
||||
================================
|
||||
|
||||
Documentation for all Adafruit-sponsored CircuitPython libraries is at:
|
||||
<https://docs.circuitpython.org/projects/bundle/en/latest/drivers.html>.
|
||||
|
||||
|
||||
CircuitPython Library Bundles
|
||||
=============================
|
||||
|
||||
Many Python libraries, including device drivers, have been written for use with CircuitPython.
|
||||
They are maintained in separate GitHub repos, one per library.
|
||||
|
||||
Libraries are packaged in *bundles*, which are ZIP files that are snapshots in time of a group of libraries.
|
||||
|
||||
Adafruit sponsors and maintains several hundred libraries, packaged in the **Adafruit Library Bundle**.
|
||||
Adafruit-sponsored libraries are also available on <https://pypi.org>.
|
||||
|
||||
Yet other libraries are maintained by members of the CircuitPython community,
|
||||
and are packaged in the **CircuitPython Community Library Bundle**.
|
||||
|
||||
The Adafruit bundles are available on GitHub: <https://github.com/adafruit/Adafruit_CircuitPython_Bundle/releases>.
|
||||
The Community bundles are available at: <https://github.com/adafruit/CircuitPython_Community_Bundle/releases>.
|
||||
|
||||
More detailed information about the bundles, and download links for the latest bundles
|
||||
are at <https://circuitpython.org/libraries>.
|
||||
|
||||
Documentation about bundle construction is at: <https://circuitpython.readthedocs.io/projects/bundle/en/latest/>.
|
||||
|
||||
Documentation for Community Libraries is not available on ReadTheDocs at this time. See the GitHub repository
|
||||
for each library for any included documentation.

:mod:`uasyncio` --- asynchronous I/O scheduler
|
||||
==============================================
|
||||
|
||||
.. module:: uasyncio
|
||||
:synopsis: asynchronous I/O scheduler for writing concurrent code
|
||||
|
||||
|see_cpython_module|
|
||||
`asyncio <https://docs.python.org/3.8/library/asyncio.html>`_
|
||||
|
||||
Example::

|
||||
import uasyncio
|
||||
|
||||
async def blink(led, period_ms):
|
||||
while True:
|

uasyncio.run(main(LED(1), LED(2)))
|
||||
|
||||
# Running on a generic board
|
||||
from machine import Pin
|
||||
uasyncio.run(main(Pin(1), Pin(2)))
|
||||
|
||||
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)
|
||||
|
||||
