Jim Mussared 1d9e489af3 extmod/modbluetooth: Add send_update arg to gatts_write.
This allows the write to trigger a notification or indication, but only to
subscribed clients. This is different to gatts_notify/gatts_indicate,
which will unconditionally notify/indicate.

Jim Mussared c737cde947 docs: Replace ufoo with foo in all docs.
Anywhere a module is mentioned, use its "non-u" name for consistency.

The "import module" vs "import umodule" is something of a FAQ, and this
commit intends to help clear that up.  As a first approximation MicroPython
is Python, and so imports should work the same as Python and use the same
name, to a first approximation.  The u-version of a module is a detail that
can be learned later on, when the user wants to understand more and have
finer control over importing.

Existing Python code should just work, as much as it is possible to do that
within the constraints of embedded systems, and the MicroPython
documentation should match the idiomatic way to write Python code.

With universal weak links for modules (via MICROPY_MODULE_WEAK_LINKS) users
can consistently use "import foo" across all ports (with the exception of
the minimal ports).  And the ability to override/extend via "foo.py"
continues to work well.

Optionally enabled via MICROPY_PY_UJSON_SEPARATORS.  Enabled by default.

For dump, make sure mp_get_stream_raise is called after
mod_ujson_separators since CPython does it in this order (if both
separators and stream are invalid, separators will raise an exception
first).

Will Sowerbutts a3675294ae esp32/machine_uart: Add flow kw-arg to enable hardware flow control.
This enables optional support for the hardware UART to use the RTS and/or
CTS pins for flow control.

The new "flow" constructor keyword specifies a bitmask of RTS and/or CTS.
This matches the interface used by machine.UART on stm32 and rp2.

Previously on ESP32 it was possible to specify which pins to use for the
RTS and CTS signals, but hardware flow control was never functional: CTS
was not checked before transmitting bytes, and RTS was always driven high
(signalling no buffer space available).  With this patch, CTS and RTS both
operate as expected.

This also includes an update to the machine.UART documentation.

Damien George 9e1b25a99e docs/library/machine: Specify initial machine.PWM class.
This adds an initial specification of the machine.PWM class, to provide a
way to generate PWM output that is portable across the different ports.
Such functionality may already be available in one way or another (eg
through a Timer object), but because configuring PWM via a Timer is very
port-specific, and because it's a common thing to do, it's beneficial to
have a top-level construct for it.

The specification in this commit aims to provide core functionality in a
minimal way.  It also somewhat matches most existing ad-hoc implementations
of machine.PWM.

See discussion in #2283 and #4237.

Damien George 3c4bfd1dec py/objexcept: Support errno attribute on OSError exceptions.
This commit adds the errno attribute to exceptions, so code can retrieve
errno codes from an OSError using exc.errno.

The implementation here simply lets `errno` (and the existing `value`)
attributes work on any exception instance (they both alias args[0]).  This
is for efficiency and to keep code size down.  The pros and cons of this
are:

Pros:
- more compatible with CPython, less difference to document and learn
- OSError().errno will correctly return None, whereas the current way of
  doing it via OSError().args[0] will raise an IndexError
- it reduces code size on most bare-metal ports (because they already have
  the errno qstr)
- for Python code that uses exc.errno the generated bytecode is 2 bytes
  smaller and more efficient to execute (compared with exc.args[0]); so
  bytecode loaded to RAM saves 2 bytes RAM for each use of this attribute,
  and bytecode that is frozen saves 2 bytes flash/ROM for each use
- it's easier/shorter to type, and saves 2 bytes of space in .py files that
  use it (for each use)

Cons:
- increases code size by 4-8 bytes on minimal ports that don't already have
  the `errno` qstr
- all exceptions now have .errno and .value attributes (a cpydiff test is
  added to address this)

Thorsten von Eicken c10d431819 esp32: Add basic support for Non-Volatile-Storage in esp32 module.
This commit implements basic NVS support for the esp32.  It follows the
pattern of the esp32.Partition class and exposes an NVS object per NVS
namespace.  The initial support provided is only for signed 32-bit integers
and binary blobs.  It's easy (albeit a bit tedious) to add support for
more types.

Damien George 2acc087880 extmod/vfs_lfs: Add mtime support to littlefs files.
This commit adds support for modification time of files on littlefs v2
filesystems, using file attributes.  For some background see issue #6114.

Features/properties of this implementation:
- Only supported on littlefs2 (not littlefs1).
- Uses littlefs2's general file attributes to store the timestamp.
- The timestamp is 64-bits and stores nanoseconds since 1970/1/1 (if the
  range to the year 2554 is not enough then additional bits can be added to
  this timestamp by adding another file attribute).
- mtime is enabled by default but can be disabled in the constructor, eg:
  uos.mount(uos.VfsLfs2(bdev, mtime=False), '/flash')
- It's fully backwards compatible, existing littlefs2 filesystems will work
  without reformatting and timestamps will be added transparently to
  existing files (once they are opened for writing).
- Files without timestamps will open correctly, and stat will just return 0
  for their timestamp.
- mtime can be disabled or enabled each mount time and timestamps will only
  be updated if mtime is enabled (otherwise they will be untouched).

Damien George 3b6c9119eb extmod/modbluetooth: Add support for changing the GAP device name.
This commit allows the user to set/get the GAP device name used by service
0x1800, characteristic 0x2a00.  The usage is:

    BLE.config(gap_name="myname")
    print(BLE.config("gap_name"))

As part of this change the compile-time setting
MICROPY_PY_BLUETOOTH_DEFAULT_NAME is renamed to
MICROPY_PY_BLUETOOTH_DEFAULT_GAP_NAME to emphasise its link to GAP and this
new "gap_name" config value.  And the default value of this for the NimBLE
bindings is changed from "PYBD" to "MPY NIMBLE" to be more generic.

Thorsten von Eicken 952ff8a8ea esp32: Improve support for OTA updates.
This commit adds several small items to improve the support for OTA
updates on an esp32:

- a partition table for 4MB flash modules that has two OTA partitions ready
  to go to do updates
- a GENERIC_OTA board that uses that partition table and that enables
  automatic roll-back in the bootloader
- a new esp32.Partition.mark_app_valid_cancel_rollback() class-method to
  signal that the boot is successful and should not be rolled back at the
  next reset
- an automated test for doing an OTA update
- documentation updates

Thorsten von Eicken a177831c46 esp32/modesp32: Add idf_heap_info(capabilities) to esp32 module.
This commit adds an idf_heap_info(capabilities) method to the esp32 module
which returns info about the ESP-IDF heaps.  It's useful to get a bit of a
picture of what's going on when code fails because ESP-IDF can't allocate
memory anymore.  Includes documentation and a test.

Andrew Leech 86bfabec11 py/modmicropython: Add heap_locked function to test state of heap.
This commit adds micropython.heap_locked() which returns the current
lock-depth of the heap, and can be used by Python code to check if the heap
is locked or not.  This new function is configured via
MICROPY_PY_MICROPYTHON_HEAP_LOCKED and is disabled by default.

This commit also changes the return value of micropython.heap_unlock() so
it returns the current lock-depth as well.

Damien George dd0bc26e65 extmod/modbluetooth: Change scan result's "connectable" to "adv_type".
This commit changes the BLE _IRQ_SCAN_RESULT data from:

    addr_type, addr, connectable, rssi, adv_data

to:

    addr_type, addr, adv_type, rssi, adv_data

This allows _IRQ_SCAN_RESULT to handle all scan result types (not just
connectable and non-connectable passive scans), and to distinguish between
them using adv_type which is an integer taking values 0x00-0x04 per the BT
specification.

This is a breaking change to the API, albeit a very minor one: the existing
connectable value was a boolean and True now becomes 0x00, False becomes
0x02.

Documentation is updated and a test added.

Fixes #5738.

Peter Hinch 88cbfd791a docs/library: Fix framebuf monochrome 1-bit modes, swapping HLSB/HMSB.
This fix can be demonstrated by the following:

    b = bytearray(32)
    f = framebuf.FrameBuffer(b, 32, 8, framebuf.MONO_HLSB)
    f.pixel(0, 0, 1)
    print('MONO_HLSB', hex(b[0]))

    b = bytearray(32)
    f = framebuf.FrameBuffer(b, 32, 8, framebuf.MONO_HMSB)
    f.pixel(0, 0, 1)
    print('MONO_HMSB', hex(b[0]))

Outcome:

    MONO_HLSB 0x80
    MONO_HMSB 0x1

Damien George 84958a8fe1 extmod/modbluetooth: Allow setting ringbuf size via BLE.config(rxbuf=).
The size of the event ringbuf was previously fixed to compile-time config
value, but it's necessary to sometimes increase this for applications that
have large characteristic buffers to read, or many events at once.

With this commit the size can be set via BLE.config(rxbuf=512), for
example.  This also resizes the internal event data buffer which sets the
maximum size of incoming data passed to the event handler.

Damien George 7aeafe2ae9 extmod/modbluetooth: Add optional 4th arg to gattc_write for write mode.
This allows the user to explicitly select the behaviour of the write to the
remote peripheral.  This is needed for peripherals that have
characteristics with WRITE_NO_RESPONSE set (instead of normal WRITE).  The
function's signature is now:

    BLE.gattc_write(conn_handle, value_handle, data, mode=0)

mode=0 means write without response, while mode=1 means write with
response.  The latter was the original behaviour so this commit is a change
in behaviour of this method, and one should specify 1 as the 4th argument
to get back the old behaviour.

In the future there could be more modes supported, such as long writes.

Jim Mussared e873d352ad extmod/modbluetooth: Simplify management of pre-allocated event data.
The address, adv payload and uuid fields of the event are pre-allocated by
modbluetooth, and reused in the IRQ handler.  Simplify this and move all
storage into the `mp_obj_bluetooth_ble_t` instance.

This now allows users to hold on to a reference to these instances without
crashes, although they may be overwritten by future events.  If they want
to hold onto the values longer term they need to copy them.

Damien George 8bec0e869d docs/machine.I2C: Add writevto method to write a vector of byte bufs.
This allows to efficiently send to an I2C slave data that is made up of
more than one buffer.  Instead of needing to allocate temporary memory to
combine buffers together this new method allows to pass in a tuple or list
of buffers.  The name is based on the POSIX function writev() which has
similar intentions and signature.

The reasons for taking this approach (compared to having an interface with
separate start/write/stop methods) are:
- It's a backwards compatible extension.
- It's convenient for the user.
- It's efficient because there is only one Python call, then the C code can
  do everything in one go.
- It's efficient on the I2C bus because the implementation can do
  everything in one go without pauses between blocks of bytes.
- It should be possible to implement this extension in all ports, for
  hardware and software I2C.

Further discussion is found in issue #3482, PR #4020 and PR #4763.

Damien George 34942d0a72 stm32/machine_uart: Change default UART timeout to 0, for non blocking.
It's more common to need non-blocking behaviour when reading from a UART,
rather than having a large timeout like 1000ms (the original behaviour).
With a large timeout it's 1) likely that the function will read forever if
characters keep trickling it; or 2) the function will unnecessarily wait
when characters come sporadically, eg at a REPL prompt.

Damien George b16146d189 docs/machine: Change sleep to lightsleep and add timeout arguments.
The machine.sleep() function can be misleading because it clashes with
time.sleep() which has quite different semantics.  So change it to
machine.lightsleep() which shows that it is closer in behaviour to
machine.deepsleep().

Also, add an optional argument to these two sleep functions to specify a
maximum time to sleep for.  This is a common operation and underlying
hardware usually has a special way of performing this operation.

The existing machine.sleep() function will remain for backwards
compatibility purposes, and it can simply be an alias for
machine.lightsleep() without arguments.  The behaviour will be the same.
