Based on active network interfaces.

Builds have been broken since reworking autogeneration in c618f91 and
related, this gets fixed here by applying similar qstr generation logic
for the msvc builds: c files are only preprocessed when changed (or not
yet preprocessed) and the concatenated output is fed into makeqstrdefs.py.
To speed up this process, the concatenated output is already filtered to
contain only lines which makeqstrdefs really needs: this makes the qstr
generation stage about twice as fast (checked on different machines).

- msvc preprocessor output contains full paths with backslashes so the
':' and '\' characters needs to be erased from the paths as well
- use a regex for extraction of filenames from preprocessor output so it
can handle both gcc and msvc preprocessor output, and spaces in paths
(also thanks to a PR from @travnicekivo for part of that regex)
- os.rename will fail on windows if the destination file already exists,
so simply attempt to delete that file first

Using usual call_function_*_protected() helper, to avoid NLR jump crashes.

They almost certainly needed by any C code which calls Python callbacks.

Update the help() implementations in the cc3200, stmhal and teensy
ports to use the pyhelp_print_obj function.
|
|
Several ports use identical code for the 1-argument form of the builtin
help function. Move this code to a library function to allow easier
re-use by ports.

Explicit .start() is required now.

Different ports may have different formats.

"ustruct" is good example of micro-ified module, so rather should belong
to the corresponding list.

Now I2C works with GPIO16 as the SCL or SDA pin.
|
|
Most pin I/O can be done just knowing the pin number as a simple
integer, and it's more efficient this way (code size, speed) because it
doesn't require a memory lookup to get the pin id from the pin object.
If the full pin object is needed then it can be easily looked up in the
pin table.

Qstr auto-generation is now much faster so this optimisation for start-up
time is no longer needed. And passing "-s -S" breaks some things, like
stmhal's "make deploy".

Addresses issue #1998.
|
|
It doesn't do anything and is not needed. ets_loop_iter/ets_event_poll
now take care of feeding the WDT.
|
|
It's now completely replaced by the ringbuf implementation.

The L4 MCU supports 40 Events/IRQs lines of the type configurable and
direct. But this L4 port only supports configurable line types which are
already supported by uPy. For details see page 330 of RM0351, Rev 1.
The USB_FS_WAKUP event is a direct type and there is no support for it.

The way to lookup the flash sector now uses a much simpler table for
all MCUs.

__GPIOI_CLK_ENABLE is defined in hal/l4/inc/Legacy/stm32_hal_legacy.h
as __HAL_RCC_GPIOI_CLK_ENABLE, and that latter macro is not defined
anywhere else (because the L4 does not have port GPIOI). So the test
for GPIOI is needed, along with the test for the CLK_ENABLE macro.

Use the machine.deepsleep() function to enter the sleep mode. Use the
RTC to configure the alarm to wake the device.
Basic use is the following:
import machine
# configure RTC's ALARM0 to wake device from deep sleep
rtc = machine.RTC()
rtc.irq(trigger=rtc.ALARM0, wake=machine.DEEPSLEEP)
# do other things
# ...
# set ALARM0's alarm to wake after 10 seconds
rtc.alarm(rtc.ALARM0, 10000)
# enter deep-sleep state (system is reset upon waking)
machine.deepsleep()
To detect if the system woke from a deep sleep use:
if machine.reset_cause() == machine.DEEPSLEEP_RESET:
print('woke from deep sleep')

Flash size as seen by vendor SDK doesn't depend on real size, but rather on
a particular value in firmware header, as put there by flash tool. That means
it's user responsibility to know what flash size a particular device has, and
specify correct parameters during flashing. That's not end user friendly
however, so we try to make it "flash and play" by detecting real size vs
from-header size mismatch, and correct the header accordingly.

E.g. for stmhal, accumulated preprocessed output may grow large due to
bloated vendor headers, and then reprocessing tens of megabytes on each
build make take couple of seconds on fast hardware (=> potentially dozens
of seconds on slow hardware). So instead, split once after each change,
and only cat repetitively (guaranteed to be fast, as there're thousands
of lines involved at most).

Not stuff like "#pragma", etc.
