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.

Jim Mussared 6250337c9c ports: Make all network-capable boards use bundle-networking.
This will ensure that any board with networking support gets:
 - webrepl
 - mip
 - urequests
 - ntptime

Jim Mussared 924a3e03ec top: Replace upip with mip everywhere.
Updates all README.md and docs, and manifests to `require("mip")`.

Also extend and improve the documentation on freezing and packaging.

Jim Mussared d84c6ef0e8 ports: Use micropython-lib version of drivers in manifests. 2022-09-08 11:27:05 +10:00
Jim Mussared 203dae41fb all: Update all manifest.py files to use new features.
Changes in this commit:
- Manifest include's now use the directory path where possible (no longer
  necessary to include the manifest.py file explicitly).
- Add manifest.py for all drivers and components that are referenced by
  port/board manifests.
- Replace all uses of freeze() with package()/module(), except for port and
  board modules.
- Use opt=3 everywhere, for consistency and to reduce code size.
- Use require() instead of include() for all micropython-lib references.
- Remove support for optional board-level manifest.py in mimxrt port, to
  make it behave the same as other ports (the board must set
  FROZEN_MANIFEST to a custom manifest.py, which can optionally include the
  default, port-level manifest).
- Also reinstates modules that were accidentally removed from the esp8266
  512k build in fbe9417b90.

Ian Davies fbe9417b90 extmod/ntptime: Factor out ntptime module from esp8266 port.
The ntptime module was previously only included in the ESP8266 port.  This
commit factors that module out into the extmod directory, makes it support
different epochs, and includes it in the rp2 port.

Jim Mussared 7ce1e0b1dc extmod/webrepl: Move webrepl scripts to common place and use manifest.
Move webrepl support code from ports/esp8266/modules into extmod/webrepl
(to be alongside extmod/modwebrepl.c), and use frozen manifests to include
it in the build on esp8266 and esp32.

A small modification is made to webrepl.py to make it work on non-ESP
ports, i.e. don't call dupterm_notify if not available.

Jim Mussared 8ba963cfa3 tools/makemanifest.py: Eval relative paths w.r.t. current manifest file.
When loading a manifest file, e.g. by include(), it will chdir first to the
directory of that manifest.  This means that all file operations within a
manifest are relative to that manifest's location.

As a consequence of this, additional environment variables are needed to
find absolute paths, so the following are added: $(MPY_LIB_DIR),
$(PORT_DIR), $(BOARD_DIR).  And rename $(MPY) to $(MPY_DIR) to be
consistent.

Existing manifests are updated to match.
