* 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
The uninitted RAM macro would fail because the OTA code would clear out the
first 50KB or so of RAM to copy its code and global values.
Move all global values to the end of RAM in OTA, and then align any uninitted
vars to a 16KB unit to ensure it won't appear in the 1st part of RAM that is
still needed to copy the OTA executable.
In the normal case, without any uninit_ram vars, no additional space is used.
When uninit_ram is used, up to 16KB of space may be lost to get that alignment,
but it will work properly.
Fixes#1188
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.
See #1129 for more info
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
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.
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
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.
Adds compiler flags to correctly build Cortex-M0/M0+ code variants for
libraries inside of the ARM CMSIS codebase.
This was tested with the Arduino_CMSIS-DSP library.
IPv4-only mode saves 20KB+ of flash memory.
Add some backwards compatibility with the global Arduino Ethernet
class when running in IPv4 only mode.

* Protect LWIP from reentrancy
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.
* Support disconnecting and reconnecting WiFi
* Add WiFiServer simple example
* Update documentation
