* 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
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
Mimics the I2S/PWMAudio/Stream interface for ease of use.
* Fix non-32b DMA size transfer calculation in ABM
* Rename wasHolding to isHolding in the I2S/PWM
It is the **current** number of bits left, not the past number.
* Add commented microphone example
* Add docs
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.
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
Call `rp2040.enableDoubleResetBootloader()` anywhere in the code to
enable the check. W/o that call, the checker will be linked in.
See #892
CORE1 doesn't start until well after the C runtime initialization,
so the flag won't be overwritten.
Also increase timeout to 350ms because OTA bootup can be
slow.
* 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
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.
Simple sketches should work without modification, but some modes (listed
in the docs) are not possible to support on the Pico W with BearSSL.
Fixes#691
IPv4-only mode saves 20KB+ of flash memory.
Add some backwards compatibility with the global Arduino Ethernet
class when running in IPv4 only mode.

* Add some examples and basic ESP8266 compat hacks
* Update Adafruit TinyUSB to fix crash
* Set DHCP hostname
* Make Wifi.begin() return CONNECTED with link + IP
* Return connected() on WiFi::begin
* Fix spurious TCP retransmission
* 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

* Fix typo
Rewrite the I2S code from scratch to eliminate the dependence on the
pico-extras implementation and to support I2S input as well.
8-bit, 16-bit, 24-bit, and 32-bit words are supported.
Multiple I2S ports are allowed (theoretically up to 6 because
2 DMA channels are required per port).
I2S input and I2S output are supported.
Add input example
Fixes#535Fixes#99Fixes#562
Using all the work from @hfellner and others, add FreeRTOS
SMP support.
Allow idling cores through the FreeRTOS FIFO queue to
allow for file system and EEPROM support.
Make delay a weak function so FreeRTOS can override.
Add cycle count support under FreeRTOS using a PIO SM.
Use a task-based approach for handling the USB periodic work
instead of the IRQ-based one in the main core.
Set 8 prio levels so it fits in 3 bits nicely (0..7).
I receive mails weekly asking how to use `SoftwareSerial` on this core.
Avoid the issue by including a simple wrapper class around `SerialPIO`
which gives the proper class name and constructor parameters.
Note that inverted mode is not supported.
Fixes#472
Instead of using interrupts, explicitly call the IRQ handler dueing Serial
read/peek/available calls.
Add to keywords.txt for syntax hilighting.
Add poll calls in the SerialUART::write-like calls (write,
flush, etc.)
Really remove division from IRQ routines/
Adds support to the core for PIO-based, software-created UARTs, up to 8 (the number of PIO state machines) possible.
By using a custom program on the PIO state machines, it allows for very high bit rates and does not require CPU or interrupts.
Bit widths from 5- to 8-bits, 1 or 2 stop bits, and even/odd/none parity are supported.

Update pico-sdk to 1.1.2
Add methods to block the opposite core while doing flash updates.
Ensure opposite core is stopped in LittleFS and EEPROM while doing
flash updates.
Update documentation with new calls.
Support running code on the second core by adding a setup1() and/or
a loop1() routine to a sketch. These functions operate exactly like
the normal Arduino ones, and anything they call will be run on
the second core automatically.
Add a simple multicore example.
