Jim Mussared 0e8af2b370 extmod/modbluetooth: Add API for L2CAP channels.
Also known as L2CAP "connection oriented channels". This provides a
socket-like data transfer mechanism for BLE.

Currently only implemented for NimBLE on STM32 / Unix.

Damien George 64180f0742 extmod/machine_i2c: Add init protocol method for generic I2C bindings.
Hardware I2C implementations must provide a .init() protocol method if they
want to support reconfiguration.  Otherwise the default is that i2c.init()
raises an OSError (currently the case for all ports).

mp_machine_soft_i2c_locals_dict is renamed to mp_machine_i2c_locals_dict to
match the generic SPI bindings.

Fixes issue #6623 (where calling .init() on a HW I2C would crash).

Jim Mussared 240b3de8bc stm32/rfcore: Depend on NimBLE only when BLE enabled.
This fixes the build for non-STM32WB based boards when the NimBLE submodule

disabled.

Jim Mussared 119c88ef17 stm32/flash: Implement WB55 flash locking.
This is needed to moderate concurrent access to the internal flash, as
while an erase/write is in progress execution will stall on the wireless
core due to the bus being locked.

This implements Figure 10 from AN5289 Rev 3.

Jim Mussared a64121b0d4 stm32/rfcore: Make RX IRQ schedule the NimBLE handler.
This commit switches the STM32WB HCI interface (between the two CPUs) to
require the use of MICROPY_PY_BLUETOOTH_USE_SYNC_EVENTS, and as a
consequence to require NimBLE.  IPCC RX IRQs now schedule the NimBLE
handler to run via mp_sched_schedule.

Jim Mussared 61d1e4b01b extmod/nimble: Make stm32 and unix NimBLE ports use synchronous events.
This changes stm32 from using PENDSV to run NimBLE to use the MicroPython
scheduler instead.  This allows Python BLE callbacks to be invoked directly
(and therefore synchronously) rather than via the ringbuffer.

The NimBLE UART HCI and event processing now happens in a scheduled task
every 128ms.  When RX IRQ idle events arrive, it will also schedule this
task to improve latency.

There is a similar change for the unix port where the background thread now
queues the scheduled task.

Jim Mussared 81e92d3d6e extmod/modbluetooth: Re-instate optional no-ringbuf modbluetooth.
This requires that the event handlers are called from non-interrupt context
(i.e. the MicroPython scheduler).

This will allow the BLE stack (e.g. NimBLE) to run from the scheduler
rather than an IRQ like PENDSV, and therefore be able to invoke Python
callbacks directly/synchronously.  This allows writing Python BLE handlers
for events that require immediate response such as _IRQ_READ_REQUEST (which
was previous a hard IRQ) and future events relating to pairing/bonding.

Damien George cc2a35b7b2 stm32/rtc: Validate the RTC prescaler on boot and change if incorrect.
Devices with RTC backup-batteries have been shown (very rarely) to have
incorrect RTC prescaler values.  Such incorrect values mean the RTC counts
fast or slow, and will be wrong forever if the power/backup-battery is
always present.

This commit detects such a state at start up (hard reset) and corrects it
by reconfiguring the RTC prescaler values.

Arrowana 922f81dfd1 extmod/machine_mem: Only allow integers in machine.memX subscript.
Prior to this change machine.mem32['foo'] (or using any other non-integer
subscript) could result in a fault due to 'foo' being interpreted as an
integer.  And when writing code it's hard to tell if the fault is due to a
bad subscript type, or an integer subscript that specifies an invalid
memory address.

The type of the object used in the subscript is now tested to be an
integer by using mp_obj_get_int_truncated instead of
mp_obj_int_get_truncated.  The performance hit of this change is minimal,
and machine.memX objects are more for convenience than performance (there
are many other ways to read/write memory in a faster way),

Fixes issue #6588.

Sébastien NEDJAR b04240cb77 stm32/Makefile: Make the generation of `firmware.bin` explicit.
The file `$(BUILD)/firmware.bin` was used by the target `deploy-stlink` and
`deploy-openocd` but it was generated indirectly by the target
`firmware.dfu`.

As this file could be used to program boards directly by a Mass Storage
copy, it's better to make it explicitly generated.

Additionally, some target are refactored to remove redundancy and be more
explicit on dependencies.

stijn fad4079778 esp32,unix: Support building C++ code.
Support building .cpp files and linking them into the micropython
executable in a way similar to how it is done for .c files.  The main
incentive here is to enable user C modules to use C++ files (which are put
in SRC_MOD_CXX by py.mk) since the core itself does not utilize C++.

However, to verify build functionality a unix overage test is added.  The
esp32 port already has CXXFLAGS so just add the user modules' flags to it.
For the unix port use a copy of the CFLAGS but strip the ones which are not
usable for C++.

Damien George 0118c07916 stm32/machine_adc: Fix ADC auto-calibration to run when ADC not enabled.
Prior to this commit, the ADC calibration code was never executing because
ADVREGEN bit was set making the CR register always non-zero.

This commit changes the logic so that ADC calibration is always run when
the ADC is disabled and an ADC channel is initialised.  It also uses the LL
API functions to do the calibration, to make sure it is done correctly on
each MCU variant.

Damien George 581d43b774 stm32/usbd_cdc_interface: Check and handle CDC TX wrap-overflow.
If the device is not connected over USB CDC to a host then all output to
the CDC (eg initial boot messages) is written to the CDC TX buffer with
wrapping, so that the most recent data is retained when the USB CDC is
eventually connected (eg so the REPL banner is displayed upon connection).

This commit fixes a bug in this behaviour, which was likely introduced in
e4fcd216e0, where the initial data in the CDC
TX buffer is repeated multiple times on first connection of the device to
the host.
