This simplifies allocating outside of the VM because the VM doesn't
take up all remaining memory by default.
On ESP we delegate to the IDF for allocations. For all other ports,
we use TLSF to manage an outer "port" heap. The IDF uses TLSF
internally and we use their fork for the other ports.
This also removes the dynamic C stack sizing. It wasn't often used
and is not possible with a fixed outer heap.
Fixes#8512. Fixes#7334.
These are moved:
* Display -> busdisplay.BusDisplay
* FourWire -> fourwire.FourWire
* EPaperDisplay -> epaperdisplay.EPaperDisplay
* I2CDisplay -> i2cdisplaybus.I2CDisplayBus
`paralleldisplay` is now `paralleldisplaybus` (and registered as
`paralleldisplay` too).
Bus related helpers are split out of display_core into bus_core.
It is in still displayio since it is a dependency of both
busdisplay and epaperdisplay.
Fixes#7667
The error message for creating an I2S object on the rp2040 platform
in CircuitPython can be misleading when the word_select and data pins
are not sequential. This change updates the error message to provide
clearer guidance by specifying "GPIO pins" instead of just "pins".
The revised message now reads:
ValueError: Bit clock and word select must be sequential GPIO pins
Closes#8058

leave as a single structure because it's more efficient to call
functions with 4 or fewer arguments, and having two struct pointers
would make `consider_instruction` have 5 arguments instead.
This allows you to initialize usb_host.Port once successfully and
then returns the same object as long as you pass the same arguments
in. It does allow you to fix incorrect pins but not switching from
one valid set to another. (It needs a reset for that.)
This also moves hcd cache operations to RAM so that they don't
access the cache when doing maintenance.
