Mark Grosen 9fb56d1562 esp32/CMakeLists: Enable multiple extra component directories in build.
The EXTRA_COMPONENT_DIRS variable is a list so adding a directory so should
be done via append, not set.  This enables boards to use other components
in the build. See:

Damien George cb31c0ae9c esp32: Add support for board-named pins and the Pin.board dict.
This adds named-pins support to the esp32 port, following other ports.
Since the name of esp32 CPU pins is just GPIOx, where x is an integer, the
Pin.cpu dict is not supported and CPU pins are just retrieved via their
existing integer "name" (the cost of adding Pin.cpu is about 800 bytes,
mostly due to the additional qstrs).

What this commit supports is the Pin.board dict and constructing a pin by
names given by a board.  These names are defined in a pins.csv file at the
board level.  If no such file exists then Pin.board exists but is empty.

As part of this commit, pin and pin IRQ objects are optimised to reduce
their size in flash (by removing their gpio_num_t entry).  The net change
in firmware size for this commit is about -132 bytes.

robert-hh 29e9573de7 esp32: Use always machine_pin_get_id for getting a Pin id.
This applies to all machine modules which have pins as arguments.  Since
machine_pin_get_id() calls pin_find(), these pin arguments may be at the
moment either integer objects or Pin objects.  That allows for instance to
write

    uart = UART(1, tx=Pin(4), rx=Pin(5))

instead of

    uart = UART(1, tx=4, rx=5)

which is consistent with other ports.  Since this handling is done at a
single place in the code, extending that scheme to accept strings for named
pins is easy.

Damien George 7d66ae603d esp32/machine_timer: Switch from legacy driver to timer HAL.
The legacy driver was deprecated in IDF v5, and crashes when the ISR
handler is called.  Instead of fixing the legacy code, this commit reworks
the machine.Timer class to use the low-level HAL driver.

Tested on ESP32, ESP32S2, ESP32S3 and ESP32C3.  Behaviour is the same as it
was before this commit, except the way the Timer object is printed, it now
gives more useful information (timer id, mode, period in ms).

This is a fix for commit bccbaa92b1fc6237f0f49a7f07cc194835fbf4e3:
- Should only wait for WIFI_EVENT_STA_START when invoked on the STA_IF
  interface.
- The WIFI_EVENT_STA_START event is generated every time the STA_IF
  interface is set active(True) and it was previously inactive, ie. not
  only after calling esp_wifi_start().
- Also wait for WIFI_EVENT_STA_STOP when deactivating the interface.
- Also wait for relevant AP events.

Damien George e4650125b8 esp32: Update port to support IDF v5.0.2.
This commit updates the esp32 port to work exclusively with ESP-IDF v5.
IDF v5 is needed for some of the newer ESP32 SoCs to work, and it also
cleans up a lot of the inconsistencies between existing SoCs (eg S2, S3,
and C3).

Support for IDF v4 is dropped because it's a lot of effort to maintain both
versions at the same time.

Brian 'redbeard' Harrington 5fe2a3f14f esp32/CMake: Change PROJECT_DIR to CMAKE_CURRENT_LIST_DIR.
This migrates the CMake variable `MICROPY_PORT_DIR` from the ESP-IDF
defined project to the component. Previously used instances of the variable
within the project definition have been migrated to
`CMAKE_CURRENT_LIST_DIR`. Within the component (the `main` subdirectory in
the ESP32 port) we define `MICROPY_PORT_DIR` using `CMAKE_CURRENT_LIST_DIR`
and subsequently use the `MICROPY_PORT_DIR` value in all locations where
`PROJECT` had previously been used.

Context:

In commit 9b90882146, initial support was added for building with the newly
introduced CMake support provided by the ESP-IDF.

Specifically, the commit message states:

> This commit adds support for building the esp32 port with CMake, and in
particular, it builds MicroPython as a component within the ESP-IDF. Using
CMake and the ESP-IDF build infrastructure makes it much easier to maintain
the port, especially with the various new ESP32 MCUs and their required
toolchains.

`PROJECT_DIR` is a variable populated by the ESP-IDF specifically and is
not stable when used with "[Pure CMake components][1]" as documented in the
ESP-IDF. It is intended to be used in the scope of the parent of the
current file (the "project") as opposed to the current file ("the
component"). Crossing into the parent scope like this works solely when the
"project" is MicroPython, but not when used as a component by other ESP-IDF
projects.

Analyzing this file, the intention is to reference the "Project" which in
the example is the parent directory. Within the [CMake variables][2]
documentation, there is one specifically defined for referencing the
directory for the CMake listfile currently being processed:
[`CMAKE_CURRENT_LIST_DIR`][3].

After making the change from `PROJECT_DIR` to `CMAKE_CURRENT_LIST_DIR`, the
reach into the parent scope defined by the ESP-IDF and the resulting CMake
interface violation is removed.

Similar to the component definition, the project `CMakeLists.txt` uses the
variable `CMAKE_SOURCE_DIR` which CMake defines as "The path to the top
level of the source tree."  This commit changes the variable to
`CMAKE_CURRENT_LIST_DIR` for the reasons cited above.

Damien George 53cb073571 esp32,esp8266: Change network.WLAN from a function to a type.
When the network module was first introduced in the esp8266 port in
ee3fec3167 there was only one interface (STA)
and, to save flash, the WLAN object was aliased to the network module,
which had just static methods for WLAN operations.  This was subsequently
changed in 9e8396accb when the AP interface
was introduced, and the WLAN object became a true class.

But, network.WLAN remained a function that returned either the STA or AP
object and was never upgraded to the type itself.  This scheme was then
copied over to the esp32 port when it was first introduced.

This commit changes network.WLAN from a function to a reference to the WLAN
type.  This makes it consistent with other ports and network objects, and
allows accessing constants of network.WLAN without creating an instance.

Glenn Moloney 7fa322afb8 esp32,esp8266: Add support for the Espressif ESP-NOW protocol.
ESP-NOW is a proprietary wireless communication protocol which supports
connectionless communication between ESP32 and ESP8266 devices, using
vendor specific WiFi frames.  This commit adds support for this protocol
through a new `espnow` module.

This commit builds on original work done by @nickzoic, @shawwwn and with
contributions from @zoland.  Features include:
- Use of (extended) ring buffers in py/ringbuf.[ch] for robust IO.
- Signal strength (RSSI) monitoring.
- Core support in `_espnow` C module, extended by `espnow.py` module.
- Asyncio support via `aioespnow.py` module (separate to this commit).
- Docs provided at `docs/library/espnow.rst`.

Methods available in espnow.ESPNow class are:
- active(True/False)
- config(): set rx buffer size, read timeout and tx rate
- recv()/irecv()/recvinto() to read incoming messages from peers
- send() to send messages to peer devices
- any() to test if a message is ready to read
- irq() to set callback for received messages
- stats() returns transfer stats:
    (tx_pkts, tx_pkt_responses, tx_failures, rx_pkts, lost_rx_pkts)
- add_peer(mac, ...) registers a peer before sending messages
- get_peer(mac) returns peer info: (mac, lmk, channel, ifidx, encrypt)
- mod_peer(mac, ...) changes peer info parameters
- get_peers() returns all peer info tuples
- peers_table supports RSSI signal monitoring for received messages:
    {peer1: [rssi, time_ms], peer2: [rssi, time_ms], ...}

ESP8266 is a pared down version of the ESP32 ESPNow support due to code
size restrictions and differences in the low-level API.  See docs for
details.

Also included is a test suite in tests/multi_espnow.  This tests basic
espnow data transfer, multiple transfers, various message sizes, encrypted
messages (pmk and lmk), and asyncio support.

David (Pololu) bf3eb9dc39 rp2/machine_i2c: Add timeout parameter for machine.I2C().
This commit adds support for the `timeout` keyword argument to machine.I2C
on the rp2 port, following how it's done on other ports.

The main motivation here is avoid the interpreter crashing due to infinite
loops when SDA is stuck low, which is quite common if the board gets reset
while reading from an I2C device.

A default timeout of 50ms is chosen because it's consistent with:
- Commit a707fe50b0 which used a timeout of
  50,000us for zero-length writes on the rp2 port.
- The machine.SoftI2C class which uses 50,000us as the default timeout.
- The stm32 port's hardware I2C, which uses 50,000us for
  I2C_POLL_DEFAULT_TIMEOUT_US.

This commit also fixes the default timeout on the esp32 port to be
consistent with the above, and updates the documentation for machine.I2C to
document this keyword argument.

David Grayson c046b23ea2 shared/runtime/pyexec: Don't allow Ctrl+C to interrupt frozen boot code.
Helps prevent the filesystem from getting formatted by mistake, among other
things.  For example, on a Pico board, entering Ctrl+D and Ctrl+C fast many
times will eventually wipe the filesystem (without warning or notice).

Further rationale: Ctrl+C is used a lot by automation scripts (eg mpremote)
and UI's (eg Mu, Thonny) to get the board into a known state.  If the board
is not responding for a short time then it's not possible to know if it's
just a slow start up (eg in _boot.py), or an infinite loop in the main
application.  The former should not be interrupted, but the latter should.
The only way to distinguish these two cases would be to wait "long enough",
and if there's nothing on the serial after "long enough" then assume it's
running the application and Ctrl+C should break out of it.  But defining
"long enough" is impossible for all the different boards and their possible
behaviour.  The solution in this commit is to make it so that frozen
start-up code cannot be interrupted by Ctrl+C.  That code then effectively
acts like normal C start-up code, which also cannot be interrupted.

Note: on the stm32 port this was never seen as an issue because all
start-up code is in C.  But now other ports start to put more things in
_boot.py and so this problem crops up.

Damien George 38e7b842c6 ports: Implement simple write polling for stdout.
This is a best-effort implementation of write polling.  It's difficult to
do correctly because if there are multiple output streams (eg UART and USB
CDC) then some may not be writeable while others are.  A full solution
should also have a return value from mp_hal_stdout_tx_strn(), returning the
number of bytes written to the stream(s).  That's also hard to define.

The renesas-ra and stm32 ports already implement a similar best-effort
mechanism for write polling.

Damien Tournoud e982c1d8de esp32/network_lan: Add support for SPI-based ethernet chips.
Add support for various SPI-based ethernet chips (W5500, KSZ8851SNL,
DM9051) to the ESP32 port.  This leverages the existing support in ESP-IDF
for these chips -- which configures these chips in "MAC raw" mode -- and
the existing support for network.LAN in the ESP32 port.  In particular,
this doesn't leverage the wiznet5k support that is used on the rp2 and
stm32 ports (because that's for native use of lwIP).

Tested on the POE Featherwing (with the SJIRQ solder jumper bridged) and a
ESP32-S3 feather.

A note about the interrupt pin: The W5500 implementation within ESP-IDF
relies on hardware interrupt, and requires the interrupt pin from the W5500
to be wired to a GPIO.  This is not the case by default on the Adafruit
Ethernet FeatherWing, which makes it not directly compatible with this
implementation.

Mark Grosen 12f9948151 esp32/machine_i2c: Fix clocks and timeouts for ESP32-C3, ESP32-S3.
Each SoC family has its own clocks and timings/timeouts. For I2C, the
default source clock is either APB (ESP32, ESP32-S2) or XTAL (ESP32-S3,
ESP32-C3) as shown in the datasheets.  Since
machine_i2c.c/machine_hw_i2c_init() uses the default clk_flags (0), the
alternate low-power clock source is never selected in ESP-IDF
i2c.c/i2c_param_config().  There is not an API in i2c.c to get the source
clock frequency, so a compile-time value is used based on SoC family.

Also, the maximum timeout is different across the SoC families, so use the
I2C_LL_MAX_TIMEOUT constant to eliminate the warning from
i2c_set_timeout().

With these changes, the following results were obtained.  The I2C SCL
frequencies were measured with a Saleae logic analyzer.

ESP32 (TTGO T Dislay)
    I2C(0, scl=22, sda=21, freq=101781)  Measured: 100KHz
    I2C(0, scl=22, sda=21, freq=430107)  Measured: 400KHz

The goal here is to remove a slot (making way to turn make_new into a slot)
as well as reduce code size by the ~40 references to mp_identity_getiter
and mp_stream_unbuffered_iter.

This introduces two new type flags:
- MP_TYPE_FLAG_ITER_IS_ITERNEXT: This means that the "iter" slot in the
  type is "iternext", and should use the identity getiter.
- MP_TYPE_FLAG_ITER_IS_CUSTOM: This means that the "iter" slot is a pointer
  to a mp_getiter_iternext_custom_t instance, which then defines both
  getiter and iternext.

And a third flag that is the OR of both, MP_TYPE_FLAG_ITER_IS_STREAM: This
means that the type should use the identity getiter, and
mp_stream_unbuffered_iter as iternext.

Finally, MP_TYPE_FLAG_ITER_IS_GETITER is defined as a no-op flag to give
the default case where "iter" is "getiter".
