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.
Fixes#687

* Add AP mode with simple DHCP server
* 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
* Update documentation
Fixes#666Fixed#665
* Update board generation, use renamed function
* Update documentation with new platform integration state
* Remove accidentally pushed file
* Use correct update command
* Use correct highlighting
* Use correct language
* Add section on debugging
* Add docs on filesystem, minor corrections
* Use -iprefix in compilation, but still expose all include paths to IDE
* Add exception and RTTI support, document them
* 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.

* Restructure filesystem size and flash size logic into platform code
* Move C++ only flags to CXXFLAGS
* Add PlatformIO documentation
* Link to new platform.io document in the docs TOC
* Fix typos in platformio docs
* Fix one additional typo in platformio.rst
* Update docs
* Remove wrongly commited build folder
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.
