Tim Radvan f842a40df4 rp2/rp2_pio: Add fifo_join support for PIO.
The PIO state machines on the RP2040 have 4 word deep TX and RX FIFOs.  If
you only need one direction, you can "merge" them into either a single 8
word deep TX or RX FIFO.

We simply add constants to the PIO object, and set the appropriate bits in
`shiftctrl`.

Resolves #6854.

Santeri Paavolainen 42035e5ede examples/embedding: Fix example so it compiles again.
There were a few changes that had broken this example, specifically
2cdf1d25f5 removed file.c from ports/unix.
And (at least for MacOS) mp_state_ctx must be placed in the BSS with
-fno-common so it is visible to the linker.

Damien George d87f42b0e5 examples/usercmodules: Simplify user C module enabling.
It's a bit of a pitfall with user C modules that including them in the
build does not automatically enable them.  This commit changes the docs and
examples for user C modules to encourage writers of user C modules to
enable them unconditionally.  This makes things simpler and covers most use
cases.

See discussion in issue #6960, and also #7086.

Damien George ad4656b861 all: Rename BYTES_PER_WORD to MP_BYTES_PER_OBJ_WORD.
The "word" referred to by BYTES_PER_WORD is actually the size of mp_obj_t
which is not always the same as the size of a pointer on the target
architecture.  So rename this config value to better reflect what it
measures, and also prefix it with MP_.

For uses of BYTES_PER_WORD in setting the stack limit this has been
changed to sizeof(void *), because the stack usually grows with
machine-word sized values (eg an nlr_buf_t has many machine words in it).

Damien George 469345e728 rp2: Add new port to Raspberry Pi RP2 microcontroller.
This commit adds a new port "rp2" which targets the new Raspberry Pi RP2040
microcontroller.

The build system uses pure cmake (with a small Makefile wrapper for
convenience).  The USB driver is TinyUSB, and there is a machine module
with most of the standard classes implemented.  Some examples are provided
in the examples/rp2/ directory.

Work done in collaboration with Graham Sanderson.

Andrew Leech 1697ff335d extmod/modbluetooth: Allow setting char/desc enc/auth options.
This widens the characteristic/descriptor flags to 16-bit, to allow setting
encryption/authentication requirements.

Sets the required flags for NimBLE and btstack implementations.

The BLE.FLAG_* constants will eventually be deprecated in favour of copy
and paste Python constants (like the IRQs).

Add working example code to provide a starting point for users with files

Damien George 06659077a8 all: Update Python code to conform to latest black formatting.
Updating to Black v20.8b1 there are two changes that affect the code in
this repository:

- If there is a trailing comma in a list (eg [], () or function call) then
  that list is now written out with one line per element.  So remove such
  trailing commas where the list should stay on one line.

- Spaces at the start of """ doc strings are removed.

Jim Mussared 9d823a5d9a extmod/modbluetooth: Add event for "indicate acknowledgement".
This commit adds the IRQ_GATTS_INDICATE_DONE BLE event which will be raised
with the status of gatts_indicate (unlike notify, indications require
acknowledgement).

An example of its use is added to ble_temperature.py, and to the multitests
in ble_characteristic.py.

Implemented for btstack and nimble bindings, tested in both directions
between unix/btstack and pybd/nimble.

Jim Mussared e6881f0829 extmod/modbluetooth: Make modbluetooth event not a bitfield.
There doesn't appear to be any use for only triggering on specific events,
so it's just easier to number them sequentially.  This makes them smaller
values so they take up only 1 byte in the ringbuf, only 1 byte for the
opcode in the bytecode, and makes room for more events.

Also add a couple of new event types that need to be implemented (to avoid
re-numbering later).

And rename _COMPLETE and _STATUS to _DONE for consistency.

In the future the "trigger" keyword argument can be reinstated by requiring
the user to compute the bitmask, eg:

    ble.irq(handler, 1 << _IRQ_SCAN_RESULT | 1 << _IRQ_SCAN_DONE)

Damien George 73c58150f5 extmod/modbtree: Retain reference to underlying stream so it's not GC'd.
For ports that have a system malloc which is not garbage collected (eg
unix, esp32), the stream object for the DB must be retained separately to
prevent it from being reclaimed by the MicroPython GC (because the
berkeley-db library uses malloc to allocate the DB structure which stores
the only reference to the stream).

Although in some cases the user code will explicitly retain a reference to
the underlying stream because it needs to call close() on it, this is not
always the case, eg in cases where the DB is intended to live forever.

Fixes issue #5940.

Jim Mussared 710426024a all: Factor gchelper code to one place and use it for unix & ARM ports.
No functionality change is intended with this commit, it just consolidates
the separate implementations of GC helper code to the lib/utils/ directory
as a general set of helper functions useful for any port.  This reduces
duplication of code, and makes it easier for future ports or embedders to
get the GC implementation correct.

Ports should now link against gchelper_native.c and either gchelper_m0.s or
gchelper_m3.s (currently only Cortex-M is supported but other architectures
can follow), or use the fallback gchelper_generic.c which will work on
x86/x64/ARM.

The gc_helper_get_sp function from gchelper_m3.s is not really GC related
and was only used by cc3200, so it has been moved to that port and renamed
to cortex_m3_get_sp.

Damien George af20c2ead3 py: Add global default_emit_opt variable to make emit kind persistent.

will be set for all compiled modules (included imports), not just the
top-level script.

Paul Sokolovsky af5b509c75 examples/unix/ffi_example: Clean up and update the ffi example.
1. Use uctypes.bytearray_at().

Implementation of the "ffi" module predates that of "uctypes", so
initially some convenience functions to access memory were added
to ffi. Later, they landed in uctypes (which follows CPython's
ctype module).

So, replace undocumented experimental functions from ffi to
documented ones from uctypes.

2. Use more suitable type codes for arguments (e.g. "P" (const void*)
instead of "p" (void*).

3. Some better var naming.

4. Clarify some messages printed by the example.

Damien George 675d1c9c60 ports: Remove typedef of machine_ptr_t, it's no longer needed.
This type was used only for the typedef of mp_obj_t, which is now defined
by the object representation.  So we can now remove this unused typedef,
to simplify the mpconfigport.h file.

Paul Sokolovsky 3d19adf9b3 examples/network: Split recv- and read-based HTTP servers.
Name recv() based a "simplistic", as it can't work robustly in every
environment. All this is to let people concentreate on proper, read()-
based one (and to turn recv() based into a "negative showcase",
explaining what are the pitfalls of such approach).
