* Add native Apple ARM silicon M1/M2/M3 support
* Identify Mac ARM in download get.py script
Thanks to the ESP32 `get.py` sources!
* Rebuild M1 w/o using strip
Avoid issues with interrupts and priority inversions and other deadlocks
and use a SW based random generator for LWIP when under FreeRTOS.
This means removing any overrides for sleep_until and the two
get_rand_xx calls from the SDK, making things much saner.
Related to #1883, #1872, and other random FreeRTOS lockups.
* Aggregated several earlier patches in one to add RP2040-Eins board into the project.
- Moved RP2040-ProMini in alphabetical order position.
- Added board description files for RP2040-Eins.
- Added board header file for RP2040-Eins.
- Adjusted unused pins order of RP2040-ProMini to be the same as in RP2040-Eins.
- Added RP2040-Eins to README.md.
- Renamed board files to use underscores to better fit the existing file naming style.
* Updated README.md
The `_idedata` has been changed to `__idedata` in newer PlatformIO core versions per 158aabbdf2. This change has broken the logic to expand out the `-iprefix PATH @INCLUDEFILE` argument into its individual include paths, causing Intellisense breakages on some VSCode systems and other IDEs that didn't handle these arguments correctly or in which the path was corrupted.
* Update to Pico-SDK v1.5
* Hook in pico_rand, use ioctl to set ipv6 allmulti
* Move into PicoSDK LWIP mutex, hack timer sizes
* Utilize much of the PicoSDK infrastructure for WiFi
* Add WiFi::begin(ssid, pass, bssid)
* WiFiMulti to use BSSID, make more robust
WiFiMulti will now be more aggressive and try all matching SSIDs, in order
of RSSI, using the BSSID to identify individual APs in a mesh.
Before, if the highest RSSI AP didn't connect, it would fail immediately.
Now, it will go down the list, ordered by RSSI, to attempt to get a link.
* Add Bluetooth support from Pico-SDK
Able to build and run the HID Keyboard Demo from the Arduino IDE, almost
as-is.
Will probably need to make BT configurable. Enabling BT on a plain WiFi
sketch uses 50KB of flash and 16KB of RAM even if no BT is used.
* Separate picow libs, BT through menus, example
Build normal Pico.a and 4 different options for PicoW IP/BT configuration.
Use IP=>IP/Bluetooth menu to select between options.
* CMakefile rationalization
* Move BT TLV(pairing) out of last 2 flash sectors
The pairing keys for BT are stored at the end of flash by default, but
we use the last sector of flash for EPROM and the penultimate one for
the filesystem. Overwriting those in BT could cause some real exciting
crashes down the line.
Move the store to an app-build specific address using a dummy const
array to allocate space in the application image itself.
* PicoBluetoothHID with BT Mouse, Joystick, Keyboard
Add simple Bluetooth Classic HID helper function and port the existing
USB HID devices to it. Port their examples.
* Protect BT key storage from multicore
* Add short-n-sweet Bluetooth documents
* Add Bluetooth Serial port library
* Turn off BT when the BT libraries exit
Without flushing STDOUT, the upload script's output aften are buffered
and not displayed until it completes. Add in flush commands to allow
the IDE to display status as it changes.
Stop the IDE from reporting large "Serial port not fount"-type errors after
every upload by delaying a bit before the uploader exits to give the OS/Pico
time to renegotiate.
Fixes flashing problems on certain Linux distros by checking all possible mount
locations instead of only the first one to be found.

The USB VID was always being set to the Raspberry Pi foundation code,
causing other brand boards to show up incorrectly.
Remove redundant values from the boards.txt and define a consistent
USB VID/PID and use it in the setup code.

Instead of listing each board three times (normal upload, picoprobe,
and pico-debug uploads), list each board once and use a menu to select
the actual upload method.
Also add in picotool as an upload method for those folks who have trouble
with automounting.
Fix#1111
SingleFileDisk allows for exporting a file from the onboard LittleFS
filesystem to a PC through an emulated FAT drive when connected. The
PC can open and copy the file, as well as delete it, but the PC has no
access to the main onboard LittleFS and no actual on-flash FAT
structures are used.
This is handy for things like data loggers. They can run connected to
USB power for some time, and then connected to a PC to dowmload the CSV
log recorded.
It's almost 2023, allow LFN (long file names) on the emulated USB disk.
Reduce the disk buffer size to 64 bytes. The buffer is statically
allocated so it's always present, even in non-USB disk mode, meaning
all apps will pay the RAM price for it. 64 bytes is slower to read
but works and saves ~1/2KB of heap for all apps.
When receiving a `QUIT` message, the main thread was trying to tell
the scanner thread to quit - however, what it was actually doing was
creating a local variable that shadowed the global flag used by the
scanner thread. Fix that by ensuring that the main thread uses the
global variable instead.

A new flexible and powerful "pluggable discovery" system was added to the Arduino boards platform framework. This system
makes it easy for Arduino boards platform authors to use any arbitrary communication channel between the board and
development tools.
Boards platform configurations that use the old property syntax are automatically translated to the new syntax by
Arduino CLI:
https://arduino.github.io/arduino-cli/latest/platform-specification/#sketch-upload-configuration
> For backward compatibility with IDE 1.8.15 and older the previous syntax is still supported
This translation is only done in platforms that use the old syntax exclusively. If `pluggable_discovery` properties are
defined for the platform then the new pluggable discovery-style `upload.tool.<protocol_name>` properties must be defined
for each board as well.
This platform includes a "UF2 Devices" discovery tool for `uf2conv` protocol ports. This tool now uses the modern
Arduino pluggable discovery system. `pluggable_discovery` properties were added to `platform.txt` in order to configure
the Arduino development tools to use this pluggable discovery tool. The `upload.tool.<protocol_name>` properties in
`boards.txt` were not updated at that time.
Global properties of that name were added to platform.txt, but this approach is not provided for by the Arduino Platform
specification:
https://arduino.github.io/arduino-cli/latest/platform-specification/#sketch-upload-configuration
> A specific upload.tool.<protocol_name> property should be defined for every board in boards.txt:
Those missing properties caused uploads to fail for users of the recent versions of Arduino IDE and Arduino CLI with an
error of the form:
Error during Upload: Property 'upload.tool.<protocol_name>' is undefined
(where `<protocol_name>` is the protocol of the selected port, if any)
It is also important to provide compatibility with versions of Arduino development tools from before the introduction of
the modern pluggable discovery system. For this reason, the old style `<board ID>.upload.tool` properties are retained.
Old versions of the development tools will treat the `<board ID>.upload.tool.<protocol_name>` properties as an unused
arbitrary user defined property with no special significance and the new versions of the development tools will do the
same for the `upload.tool` properties.
Random crashes, infinite loops, and other lockups were happening to the PicoW
while under high load from multiple clients.
This seems to have been due to two issues:
* The periodic sys_check_timeouts() call from an alarm/IRQ was happening while
the core was in LWIP code. LWIP is not re-entrant or multi-core/thread safe
so this is a bad thing. Some calls may not have been locked with a manual
addition of the LWIPMutex object to hit this.
* The WiFi driver supplies packet data during an interrupt. PBUF work is
legal in an interrupt, but actually calling netif->input() from an IRQ to
queue up the Ethernet packet for processing is illegal if LWIP is already
in progress.
Rearchitect the LWIP interface to fix these problems:
* Disable interrupts during malloc/etc. to avoid the possibility of the
periodic LWIP timeout check interrupting and potentially calling user
code which did a memory operation
* Wrap all used LWIP calls to note LWIP code will be executing, instead of
manually eyeballing and adding in protection in user code.
* Remove all user code LWIPMutex blocking, the wrapping takes care of it.
* When an Ethernet packet is received by interrupt and we're in LWIP code,
just throw the packet away for now. The upper layers can handle retransmit.
(A possible optimization would be to set the packet aside and add a
housekeeping portion to the LWIP wrappers to netif->input() them when safe).
* Ignore callbacks during TCP connection teardown when the ClientContext
passed from LWIP == nullptr
Allow the IDE to detect UF2 volumes (i.e. when you hold BOOTDEL and
plug in the board).
Allows the IDE2 to properly upload using OTA and serial.
Fixes#890 and others
Because OTA has changed the flash map from standard, picotool ends up
crashing or hanging while trying to operate on the current built files.
Remove the binary_info calls and structures completely to avoid any
issue.
Fixes#803
* Add HTTP-parser lib to support ESP32 WebServer
* Add WebServer from ESP32. Only supports HTTP
* Separate HTTP server from the network server
Instead of managing the WiFiServer/WiFiServerSecure in the same object
as the HTTP handling, split them into separate objects. This lets
HTTP and HTTPS servers work without templates or duplicating code.
The HTTP block just gets a `WiFiClient*` and works with that to only
do HTTP processing, while the upper object handles the appropriate
server and client types.
* Add HTTPS server
* Clean up some THandlerFunction refs
* Refactor into a template-ized WebServer/WebServerSecure
* Add DNSServer examples which need WebServer
* Fix CoreMutex infinite recursion crash
Core could crash while Serial debugging was going on and prints were
happening from LWIP/IRQ land and the main app.
* Add HTTPUpdateServer(Secure)
* Add MIME include, optimize WebServer::send(size,len)
When send()ing a large buffer, the WebServer::send() call would
actually convert that buffer into a String (i.e. duplicate it, and
potential issues with embedded \0s in binary data).
Make a simple override to send(size, len) to allow writing from the
source buffer instead.
* Fix WiFiClient::send(Stream), add FSBrowser example
* Add HTTPUpdate class to pull updates from HTTP(S)
* Increase GH runners for pulls
WiFi builds and examples are taking some serious time now
* HTTPUpdate tests build on Pico W
Remove the need to have a separate WiFiClient that's destroyed after
the HTTPClient. Let the object handle its own client, and pass through
any SSL requests.
Also supports the original ::begin methods which need a
WiFiClient(Secure) to be passed in and managed by the app.
Adds a 12K OTA stub 3rd stage bootloader, which reads new firmware
from the LittleFS filesystem and flashes on reboot.
By storing the OTA commands in a file in flash, it is possible to
recover from a power failure during OTA programming. On power
resume, the OTA block will simply re-program from the beginning.
Support cryptographic signed OTA updates, if desired. Includes
host-side signing logic via openssl.
Add PicoOTA library which encapsulates the file format for
the updater, including CRC32 checking.
Add LEAmDNS support to allow Arduino IDE discovery
Add ArduinoOTA class for IDE uploads
Add MD5Builder class
Add Updater class which supports writing and validating
cryptographically signed binaries from any source (http,
Ethernet, WiFi, Serial, etc.)
Add documentation and readmes.

The send buffers are set to 8 * MSS = ~11.5K. MEM_SIZE is now set to
be larger than that, 16K, in order to help avoid having tcp_write fail
with ENOMEM. The attempt to use a smaller size is still included, which
will allow a tcp_write of up to 16 * 16K = 256K, i.e. all of memory.
Fixes#725
Increases the MEM_SIZE outstanding write buffer to 8K
Allows the ClientContext to attempt to send smaller buffer chunks in the
case where MEM_SIZE won't allow the full tcp_sndbuf() transfer.

The Pico SDK calls "sys_check_timeouts() from inside a periodic interrupt.
This appears unsafe, as the interrupt could happen while already in the
(non-reentrant) LWIP code.
Block the interrupt from calling sys_check_timeouts by using a global flag
manually set via an RAII recursive lock.
Add interrupt protection macros around critical sections inside LWIP via
the standard defines.
These two changes should make LWIP significantly more stable and long
running.

Blink.ino shows a savings of 3.5KB flash and 400 bytes of RAM.
For comparison, with this PR blink.ino reports:
````
Sketch uses 49908 bytes (3%) of program storage space. Maximum is 1568768 bytes.
Global variables use 7024 bytes (2%) of dynamic memory, leaving 255120 bytes for local variables. Maximum is 262144 bytes.
````
As comparison, using the MBED core blink.ino reports:
````
Sketch uses 78882 bytes (0%) of program storage space. Maximum is 16777216 bytes.
Global variables use 42780 bytes (15%) of dynamic memory, leaving 227556 bytes for local variables. Maximum is 270336 bytes.
````
So, with this PR we use **37% less flash** and and **87% less RAM**
for simple sketches.
When get.py is run in a script the percent-update printouts shown while
downloading the toolchain end up as 100s to 1000s of lines in log files.
When stdout is not a terminal, avoid printing these percentages and

The chip supports 133MHz and the other Pico core already defaults to
the higher speed, so make 133 the default.
It can still be changed through the menus and will stay at 125 unless
pre-existing users change it so they will see no difference.
Microsoft is deprecating WMIC, so fall back to a Powershell call in
case of failure to ruin WMIC.
Belt and suspenders, set PowerShell non-interactive mode and null STDIN.
Fixes a crash of the builder script, `board.get("build.variant", None)` will throw an exception if the `build.variant` was not found (and not return `None` as the fallback value), but an empty string works, so check against that.
USB power defines moved directly into the board files, but still ensure that the macro always exists (with a default fallback value) to not fail the build.
Defines USBD_MAX_POWER_MA as a static 250mA, which is correct for all the boards supported in platform-raspberrypi (aka, RaspberryPi Pico and Nano RP2040 Connect)
