Boards with selectable flash sizes only had a 1MB FS as the smallest
option on 2MB boards. For the normal Pico @ 2MB, though, we supported
filesystems down to 64KB. Add those same options to the 2MB SKUs
of configurable boards.
* Initial commit.
* Works with AK4619 in TDM128 I2S compatibility mode set to rising BCLK.
* Works with I2S compat mode with BCLK mode set to 0 on AK4619.
Windows Python doesn't seem to kill the worker Thread properly when the IDE
is exited, leading to a) multiple Python3 instances on a PC after many uses
and b) errors updating the core when it tries to re-install Python3 while
still having the older version's EXE loaded and in use.
When an exception happens on the input() call under Windows, it seems like it
can still leave a thread running. Add one more flag, caught in a global
exception handler.

Supercedes #2815
Move to pico-sdk official develop branch which includes a necessary
IRQ header fix.
200MHz is now default for the Pico, but 133 is still available from
the menus.
My application is designed to generate HSTX data on core0 in interrupts,
but also uses hardware SPI for SD card access.
It turns out that the amount of time spent in maskInterrupts/
unmaskInterrupts, even with an empty _usingIRQs, is too long.
Add a quick check and avoid touching the interrupt disable flag if
there's not actually any GPIO interrupt to (un)mask.
* Adjust the PSRAM clock when over/underclock F_SYS
Fixes#2818
* Need to increase PSRAM divider before sysclk increase
Per datasheet, when increasing sysclk speed we need to set the qmi
clocks first and do a dummy transfer to ensure no invalid speed
operations happen on the bus. Handle the logic for this while setting
up the overclock.
* Move to Arduino API 10501
Track upstream Arduino API headers
* IPAddress V4/V6 compatiblity restored
* Fix WiFiUDP includes
* String differences in example
* HardwareSerial using exported
* Add PIO-based SoftwareSPI enabling SPI on any pins
The Raspberry Pi team has a working PIO-based SPI interface. Wrap it
to work like a hardware SPI interface, allowing SPI on any pin
combination.
Tested reading and writing an SD card using unmodified SD library.
* Add W5500 example
Good for testing, shows non-contiguous pin outs.
* Added buffer read to `AudioBufferManager` and `I2S`. Example and documentation included.
* Update type of words to unsigned in example.
* Improve buffered loopback example.
* Remove const from read buffer.
* Don't set SDFAT_FILE_TYPE, default is OK
Fixes#2772
No need to set SDFAT_FILE_TYPE=3 as that is the defaulr value with upstream
SdFat. Remove it from platform.txt and platform.io build.
* Codespell got all techy
