Adds support for hardware SPI to the zephyr port. Consistent with other
ports, such as rp2 and stm32, we only implement the SPI protocol functions
(init and transfer). Explicit sck/mosi/miso selection is not supported
and new SPI instances are initialized with default values.
This commit adds I2S protocol support for the esp32 and stm32 ports, via
a new machine.I2S class. It builds on the stm32 work of blmorris, #1361.
Features include:
- a consistent I2S API across the esp32 and stm32 ports
- I2S configurations supported:
- master transmit and master receive
- 16-bit and 32-bit sample sizes
- mono and stereo formats
- sampling frequency
- 3 modes of operation:
- blocking
- non-blocking with callback
- uasyncio
- internal ring buffer size can be tuned
- documentation for Pyboards and esp32-based boards
- tested on the following development boards:
- Pyboard D SF2W
- Pyboard V1.1
- ESP32 with SPIRAM
- ESP32

This change allows specification of the idle level and TX carrier output

The Makefile had to be changed in order to build the .bin file as well.

Since the new keypad module is taking over gamepad functionality,
I'm switching to it. If this works well, I will make the change
for the remaining boards.
This avoids the irritation of the PJRC HalfKay loader on Teensy 4.0. Block
0 and 1 are properly erased and the additional formatting in the make
script is not required anymore.
This class supports SPI bus controller mode, with blocking transfers.
SPI device numbers start at 0, to comply with the pinout of the Teensy
boards. With the configured clock frequency the fastest baud rate is
33MHz. For messages longer 16 bytes DMA is used. The class uses the
existing framework with extmod/machine_spi.c.
Extended driver options:
- drive=n with n being between 1 and 6 or PIN.POWER_1 to PIN.POWER_6.
Since the pins used by the SPI are fixed, no Pin settings can be made.
Thus the drive option is added allowing to control ringing and crosstalk
on the connection.
- gap_ns=nnnnn is the time between sent data items in a frame given in ns.
Default is 2 clock cycles.
When looping, now disable the TX interrupt after calling rmt_write_items()
function to handle change in IDF behaviour (since v4.1). Also check length
of pulses to ensure it fits hardware limit.

Calculating the weekday each time you want to set a date is error prone and
tiresome. MicroPython can do it on its own - hardware on some ports do not
support storing weekday in hardware and always computes it on the fly,
ignoring the value given to the constructor.
During discussion for #7432 the conclusion was that there seems to be no
obvious reason to let user set the weekday to an incorrect value so it
makes sense to just ignore the provided weekday value and always compute
the correct value. This patch introduces this change for the rp2 port.

The RTC in rp2 can store any, even wrong, number as a weekday in RTC. It

convention. It also fixes the example in quickref to use proper weekday to

nRF CircuitPython boards will now provide the file transfer
service defined here: https://github.com/adafruit/Adafruit_CircuitPython_BLE_File_Transfer
USB capable boards will only advertise if previously bonded to a
device or if the reset button is pressed during the fast blue
flashes on start up. When pressed, the board will restart again but
the blue period will not flash.
Boards without USB will always advertise.
When previously bonded, the advertisement is private so that no
other peers can connect. If advertising publicly, the tx power is
lowered to reduce the likelihood of bonding from a distance.
This PR also fixes issues with loading identities of bonded peers
so that our address can now be resolved and we can resolve others'
addresses when scanning.
Add an optional 'lock' kwarg to callback that locks GC and scheduler. This
allows the callback to be invoked asynchronously in 'interrupt context',
for example as a signal handler.
Also add the 'cfun' member function to callback, that allows retrieving the
C callback function address. This is needed when the callback should be
set to a struct field.

The rtc_set_datetime() from pico-sdk will validate the values in the
datetime_t structure and refuse to set the time if they aren't valid. It
makes sense to raise an exception if this happens instead of failing
silently which might be confusing (as an example, see:
https://github.com/micropython/micropython/pull/6928#issuecomment-860166044
).
The supplied value for microseconds in datetime() will be treated as a
starting value for the reported microseconds. Due to internal processing
in setting the time, there is an offset about 1 ms.
This change moves the datetime tuple format back to the one used by all the
other ports:
(year, month, day, weekday, hour, minute, second, microsecond)
Weekday is a number between 0 and 6, with 0 assigned to Monday. It has to
be provided when setting the RTC with datetime(), but will be ignored on
entry and calculated when needed.
The weekday() method was removed, since that is now again a part of the
datetime tuple.
The now() method was updated so it continues to return a tuple that matches
CPython's datetime module.
Initial support for machine.RTC on rp2 port. It only supports datetime()
method and nothing else. The method gets/returns a tuple of 8 items, just
like esp32 port, for example, but the usec parameter is ignored as the RP2
RTC only works up to seconds precision.
The Pico RTC isn't very useful as the time is lost during reset and there
seems to be no way to easily power up just the RTC clock with a low current
voltage, but still there seems to be use-cases for that, see issues #6831,
and a Thonny issue #1592. It was also requested for inclusion on v1.15

Leave our desired differences, including:

* adding ulab tests
* Adding "." to the import path for skip_if
This speeds up `make test_full` and should also reduce the time in CI
a little bit.
Initial version, using the LP RTC clock. It provides setting the date and
time with rtc.init() or rtc.datetime(), and reading the date and time with
rtc.datetime() or rtc.now(). The method weekday() reports the weekday of
the current date. It starts with 0 for Monday.
The tuple order for datetime() and now() matches the CPython sequence:
(year, month, day, hour, minute, second, microsecond, TZ). TZ is ignored
and reported as None. Microsecond is provided at a best effort.
If a battery is not supplied, the default boot date/time is 1970/1/1 0:0:0.
With a battery, the clock continues to run even when the board is not
powered. The clock is quite precise. If not, using rtc.calibration() may
help.
It supports three hardware timer channels based on the PIT timers of the
MIMXRT MCU. The timer id's are 0, 1 and 2. On soft reboot all active
timers will be stopped via finalisers.
This is required since the Teensy Halfkay loader attempts to erase all of
the flash but fails to do so, at least in my tests. Formatting brings it
back to a known state.
This commit adds full support for a filesystem on all boards, with a block
device object mimxrt.Flash() and uos.VfsLfs2 enabled.
Main changes are:
- Refactoring of linker scripts to accomodate reserved area for VFS. VFS

reserved for flash configuration, interrupts, etc.
- Addition of _boot.py with filesystem init code, called from main.c.
- Definition of the mimxrt module with a Flash class in modmimxrt.[ch].
- Implementation of a flash driver class in mimxrt_flash.c. All flashing
related functions are stored in ITCM RAM.
- Addition of the uos module with filesystem functions.
- Implementation of uos.urandom() for the sake of completeness of the uos
module.

Leaving the bootloader from an IRQ (eg USB or I2C IRQ) will not work if
MBOOT_LEAVE_BOOTLOADER_VIA_RESET is disabled, ie if mboot jumps directly to

The status flashes fallback to the HW_STATUS LED if no RGB LED is

DotStars and NeoPixels will hold the color until the user overrides

As a side-effect, a bunch more files are re-formatted now. :-P
This fixes some missing and incorrectly-assigned pins for the SparkFun Thing Plus RP2040 protoboard so that they actually match what the board says. This also changes the default SPI pins from the SD card pins to the breakout pins on the side of the board.
This board does not work with CONFIG_NETWORKING enabled. And
CONFIG_CONSOLE_SUBSYS is enabled so that ctrl-C works.

And ctrl-C can now interrupt a time.sleep call. This uses Zephyr's k_poll
API to wait efficiently for an event signal, and an optional semaphore.

This helper is added to properly set a pending exception, to mirror
mp_sched_schedule(), which schedules a function.
Signed-off-by: Damien George <damien@micropython.org>
If MICROPY_ENABLE_SCHEDULER is enabled then MP_STATE_VM(sched_state) must
be updated after handling the pending exception, which is done by the
mp_handle_pending() function.

This can now be selected by setting MICROPY_HW_SDIO_SDMMC, which defaults
to 1, ie SDMMC1. The pins can also be selected and default to the standard

MICROPY_HW_SDMMC_BUS_WIDTH to MICROPY_HW_SDCARD_BUS_WIDTH.

A board can now define MBOOT_TEXT0_ADDR to place mboot at a location other
than 0x08000000. This can be useful if, for example, there is already a
different bootloader on the device.

A board can now define MBOOT_LD_FILES (at the Makefile-level) to specify
custom linker scripts. And stm32_generic.ld has been split into 2 pieces
so one or the other can be reused (usually stm32_sections.ld wolud be
reused by a board, and stm32_memory.ld redefined).

A board can now use BUILDING_MBOOT at the Makefile-level to do things

Commit 1e297c8898 introduced a bug where the
very first reset-mode state on the LEDs was not shown, because prior to
that commit the first reset-mode state was the same as the initial LED
state (green on, others off) and update_reset_mode() was called after
setting this initial LED state.
This is fixed in this commit by changing the update_reset_mode() loop so
that it displays the current reset mode before doing the delay.

And use the same boardctrl.h header for both the application and mboot so
these constants are consistent.

This adds support for making static (ie not on the Python GC heap) soft
timers. This can be useful for a board to define a custom background
handler, or eventually for BLE/network processing to use instead of systick
slots; it will be more efficient using soft timer for this.
The main issue with using the existing code for static soft timers is that
it would combine heap allocated and statically allocated soft_timer_entry_t
instances in the same pairing-heap data structure. This would prevent the
GC from tracing some of the heap allocated entries (because the GC won't
follow pointers outside the heap).
This commit makes it so that soft timer entries are explicitly marked,
instead of relying on implicit marking by having the root of the pairing
heap in the root pointer section. Also, on soft reset only the heap-
allocated soft timers are deleted from the pairing heap, leaving the
statically allocated ones.

This commit re-enables the command-line make option "FROZEN_MANIFEST". The
boards/*/mpconfigboard.cmake will now use the command-line FROZEN_MANIFEST
value if supplied.
Usage: make FROZEN_MANIFEST=~/foo/my-manifest.py
Unify USB-related makefile var and C def as CIRCUITPY_USB.
Always define it as 0 or 1, same as all other settings.
USB_AVAILABLE was conditionally defined in supervisor.mk,
but never actually used to #ifdef USB-related code.
Loosely related to #4546
Because "find_package(Python3 ...)" requires at least this version of
CMake. And other features like GREATER_EQUAL and COMMAND_EXPAND_LISTS need
at least CMake 3.7 and 3.8 respectively.

Improvements are:
- Default period is 1000ms with callback disabled.
- if period is not specified then it's not updated (previously, if period
was not specified then it was set to -1 and running the timer callback as
fast as possible, making the REPL unresponsive).
- Use uint64_t to compute delta_ms, and raise a ValueError if the period is
too large.
- If callback is not specified then it's not updated.
- Specifying None for the callback will disable the timer.

Added board definition for the Sparkfun MicroMod RP2040.
Mostly followed the format for pins from the MicroMod nRF52840 board
definition, as MicroMod tries to standardize pins across
microcontrollers.
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.

Commit 8a917ad252 added the gpio_reset_pin()
call to make sure that pins that were used as ADC inputs could subsequently
be used as digital IO. But calling gpio_reset_pin() will enable the
pull-up on the pin and so pull it high for a brief period. Instead use
rtc_gpio_deinit() which will just reconfigure the pin as a digital IO and
do nothing else.
Fixes issue #7079 (see also #5771).

This is handy for remote characteristics because it allows for
the PacketBuffer binding code to have the correct max size. This
PR also adds checks so we don't write outside the outgoing buffer.
For an unconnected TCP socket, poll should return WR|HUP and read should
raise ENOTCONN. This is implemented by this commit and now the following
tests pass on esp32: extmod/usocket_tcp_basic.py,
net_hosted/connect_poll.py.
