This makes it so that all a port needs to do is set the relevant variables
and "include extmod.mk" and doesn't need to worry about adding anything to
OBJ, CFLAGS, SRC_QSTR, etc.
Make all extmod variables (src, flags, etc) private to extmod.mk.
Also move common/shared, extmod-related fragments (e.g. wiznet, cyw43,
bluetooth) into extmod.mk.
Now that SRC_MOD, CFLAGS_MOD, CXXFLAGS_MOD are unused by both extmod.mk
(and user-C-modules in a previous commit), remove all uses of them from
port makefiles.

This applies to nimble, btstack, axtls, mbedtls, lwip.
Rather than having the ports individually manage GIT_SUBMODULES for these
components, make extmod.mk append them when the relevant feature is
enabled.

This conflicts with the triple-usage of these variables for user-C-modules
and extmod source.
For CFLAGS_MOD, just use CFLAGS directly. For SRC, use SRC_C directly as
the relevant files are all guarded by the preprocessor anyway.

Removes the need for the port to add anything to OBJS or SRC_QSTR.
Also makes it possible for user-C-modules to differentiate between code
that should be processed for QSTR vs other files (e.g. helpers and
libraries).

It now prints lines like:
Pin("D9", mode=IN, pull=PULL_UP, GPIO=PA07)
or
LED("LED")
showing for consistency the names as given in pins.csv. For pins, the GPIO
numer is printed as well for a reference.
Porting PR #8040 by @hoihu to SAMD, following the commit
5873390226.
One small addition: before executing keyboard interrupt, the input buffer
is cleared.
Changes are:
- The pin-af-table-SAMDxx.csv file are moved to the mcu directories with
the name as pin-af-table.csv.
- The handling in Makefile and pin_af.c is simplified.
Two new compile flags are:
MICROPY_HW_DFLL_USB_SYNC: Effective only if DFLL48 does not run from the
crystal. It will synchronize the DFLL48M clock with the USB's SOF pulse.
If no USB is connected, it will fall back to open loop mode. The DFLL48M
clock is then pretty precise, but with a higher clock jitter at SAMD51
devices.
MICROPY_HW_MCU_OSC32KULP: Effective only if the devics uses a crystal as
clock source. Run the MCU clock from the ULP 32kHz oszillator instead of
the crystal. This flag was added to cater for a interference problem of
the crystal and Neopixel/Debug pins at Adafruit FEATHER Mx boards, which
causes the board to crash. Drawback: ticks_ms() and time.time() vs. than
ticks_us() and the peripherals like PWM run at not synchronous clocks.
Changes are:
- Set the feature level for each MCU: CORE features for SAMD21, and EXTRA
features for SAMD51.
- Remove all definitions that are included in the core feature level.
- Keep the default settings for feature level and float, to make the choice
obvious.
The SAMD21 implementation is an adaption of @jimmo's code for STM32Lxx.
The only changes are the addresses and names of the port registers and the
timing parameters.
SAMD21: The precision is about +/-25ns at 48MHz clock frequency. The first
two cycles are about 40-60 ns longer than set. But still good enough to
drive a neopixel device.
SAMD51: The precision is about +/-30ns at 120MHz clock frequency. Good
enough to drive a neopixel device.
And use mp_hal_ticks_us() for SAM21's mp_hal_ticks_cpu(). The SAMD21 has
no CYCCNT register, and the SysTick register has only a 1 ms span (== 48000
count range).
Fixes are:
- Pin definitions for ADAFRUIT_FEATHER_Mx_EXPRESS and
ADAFRUIT_ITSYBITSY_M4_EXPRESS.
- For ADAFRUIT_ITSYBITSY_M0_EXPRESS, change the MISO/MOSI name.
- For MINISAM_M4, add the default SPI pins.
- For boards with 32k crystal, add the XOSC32K setting.
It can be enabled/disabled by a configuration switch. The code size
increase is 308 bytes, but it requires RAM space for buffers, the larger
UART object and root pointers.
Allowing to set a time and retrieve the time. It is based on systick_ms()
with the precision of the MCU clock. Unless that is based on a crystal,
the error seen was about 0.5% at room temperature.
It suuports 1 channel @ 10 bit for SAMD21, 2 channels @ 12 bit for SAMD51.
Instantiation by:
dac = machine.DAC(ch) # 0 or 1
Method write:
dac.write(value)
The output voltage range is 0..Vdd.
By reducing the methods to on(), off(), toggle() and call, and using the
method implementation of the machine.Pin class.
The code size reduction is 756 byte.
All board pins that have UART's assigned can be used. Baud rate range is
75 Baud to ~2 MBaud.
No flow control yet, and only RX is buffered. TX buffer and flow control
may be added later for SAMD51 with its larger RAM and Flash.
Its API conforms to the docs. There are 16 IRQ channels available, which
will be used as assignable to the GPIO numbers. In most cases, the irq
channel is GPIO_no % 16.
