Implements dictionary union according to PEP 584's specifications, minus
the fact that dictionary entries are not guaranteed to be in insertion
order. This feature is enabled with MICROPY_CPYTHON_COMPAT.
Includes a new test.

The original ESP32 only supports timer source clock APB so it doesn't need
and doesn't have a clk_src field.
The ESP32C3 supports timer source clock APB and XTAL so it does have a
clk_src field, and this needs to be configured to get the correct period.
Fixes #8084.

This shows how ports can add their own custom types/classes.
It is part of the unix coverage build, so we can use it for tests too.

If a CMake-build is run with `make BUILD=/outside/path` then
makeversionheader.py is run with the CWD set to the build directory, which
means the git version lookup will fail and silently fall back to the
mpconfig.h mode (giving the wrong result).
This commit:
- Uses the location of makeversionheader.py to find the repo path.
- Allows overriding this path via --repo-path.

MSVC doesn't define `__i386__` or `__x86_64__` so we have to check
`_M_IX86` and `_M_X64` as well.

`_WIN64` is defined for all 64-bit targets, including Arm, so it doesn't
work for detecting `x86_64`. We can use `_M_X64` instead.

For STM32L4, hardware I2C can be implemented by using TIMINGR.
This commit enables:
- Use of hardware I2C in machine.I2C.
- Specifying a frequency greater than or equal to 400KHz with pyb.I2C.
|
|
For STM32L1, hardware I2C can be implemented the same as STM32F4 for
machine.I2C.
Tested on NUCLEO-L152RE.
|
|
TS_CAL1 and TS_CAL2 of STM32L4 are at VDDA=3.0V, so the reference
correction factor should be updated before reading tempsensor.
|
|
For STM32L4 series, the internal sensors are connected to:
- ADC1_IN0: Internal voltage reference
- ADC1_IN17: Temperature sensor
- ADC1_IN18: VBAT battery voltage monitoring
but ADC_CHANNEL_VREFINT, ADC_CHANNEL_VBAT, ADC_CHANNEL_TEMPSENSOR are not
defined as 0, 17, 18.
This commit converts channel 0, 17, 18 to ADC_CHANNEL_x in
adc_get_internal_channel().
|
|
Prior to this commit, the actual I2C frequency can be faster than specified
one and it may exceed the I2C's specification for Fast Mode. The frequency
of SCL should be less than or equal to 400KHz in Fast Mode.
This commit fixes this issue for F4 MCUs by rounding up the division in the
frequency calculation.

Excuting the code:
i2c = I2C(1, I2C.CONTROLLER, dma=True)
tmp = i2c.recv(1, i2c_addr)
recv_data = bytearray(56)
i2c.recv(recv_data, i2c_addr)
The second i2c.recv() fails with OSError: [Errno 110] ETIMEDOUT. When
receiving greater than or equal to 2 bytes at first i2c.recv(), the second
i2c.recv() succeeds. This issue does not occur without DMA.
Details of change: when executing I2C with DMA:
- Bit 11 of I2Cx_CR2 (DMA Request Enable) should be 1 to indicate that DMA
transfer is enabled. This bit is set after I2C event interrupt is
enabled in HAL_I2C_Master_Transmit_DMA()/HAL_I2C_Master_Receive_DMA(), so
DMA Request Enable bit might be 0 in IRQHandler.
- In case of data receive:
- When only 1 byte receiption, clear I2Cx_CR1's bit 10 (ACK).
- When only 2 byte receiption, clear I2Cx_CR1's bit 10 (ACK) and set
bit 11 (POS).
- When greater than or equal to 2 byte receiption, bit 12 of I2Cx_CR2
(DMA Last Transfer) should set to generate NACK when DMA transfer
completed.
Otherwise, the I2C bus may be busy after received data from peripheral.

Instead of defining `MICROPY_PY_BTREE` in `mpconfigport.h` we can define
it via CMake similar to how other ports that use Makefiles define it in
`mpconfigport.mk`.

This will make mpy-cross auto-detect. Allow overriding for non-default

Also use armv7m by default for qemu-arm (the default qemu target is
Cortex-M3).

If `-march` isn't set then it means the user hasn't thought about it, or in
the case of freezing, MPY_CROSS_FLAGS isn't set. It's almost certainly
going to lead to problems, as there's no reason why the host architecture
is likely to be the right choice.
Compiling regular Python code is unaffected, but if `@native`/`@viper` is
used, the compiler will raise `SyntaxError: invalid arch`.
For situations where you explicitly want to use the host architecture (e.g.
for running tests on the unix port), added -march=host that keeps the old
behavior.

The RT1176 has two cores, but the actual firmware supports only the CM7.
There are currently no good plans on how to use the CM4.
The actual MIMXRT1170_EVK board is on par with the existing MIMXRT boards,
with the following extensions:
- Use 64 MB RAM for the heap.
- Support both LAN interfaces as LAN(0) and LAN(1), with LAN(1)
being the 1GB interface.
The dual LAN port interface can eventually be adapted as well for the
RT1062 MCU.
This work was done in collaboration with @alphaFred.

Before this patch, WiFi connection was blocking, and could raise exceptions
if the connection failed for any reason (including timeouts). This doesn't
match the behavior of other WiFi modules, which connect asynchronously, and
requires handling of exceptions on connect. This change makes `connect()`
work asynchronously by scheduling code to poll connection status, and
handle reconnects (if needed), and return immediately without blocking.

Otherwise the pin stays in open drain mode.
Signed-off-by: Damien George <damien@micropython.org>

The PWM module now detects if the pin is open drain and if so switches it
to hardware open drain before starting the PWM.
The code that was explicitly turning off the open drain output during PWM
is also removed.
Together these changes allow driving external transistor high-current
switches with PWM.
