The initial problem with a wrong ICMP checksum was caused by
the test code setting a checksum and the HW taking that probably as
the start value and ending up with 0xffff. With a checksum field of 0
set by the test code the HW creates the proper checksum.
Useful for boards without a PHY interface, where that has to be
attached. Like the Seed ARCH MIX board or Vision SOM. Phy drivers
supported so far are:
- KSZ8081
- DP83825
- LAN8720
More to come. Usage e.g.:
lan = LAN(phy_type=LAN.PHY_LAN8720, phy_addr=1)
The default values are those set in mpconfigboard.h.
UART 0 is attached to the Debug USB port. The settings are
115200 Baud, 8N1.
For MIMXRT1010_EVK this is identical to UART1. For the other boards,
this is an additional UART.
The pico-sdk 1.3.0 update in 97a7cc243b
introduced a change that broke RP2 Bluetooth UART, and possibly UART in
general, which stops working right after UART is initialized. The commit
raspberrypi/pico-sdk@2622e9b enables the UART receive timeout (RTIM) IRQ,
which is asserted when the receive FIFO is not empty, and no more
characters are received for a period of time.
This commit makes sure the RTIM IRQ is handled and cleared in
uart_service_interrupt.
The current ST HAL does not support reading the extended CSD so cannot
correctly detect the capacity of high-capacity cards. As a workaround, the
capacity can be forced via the MICROPY_HW_MMCARD_LOG_BLOCK_NBR config
option.

Any board with a board.json file will be built. ESP32-based boards will be
built using the IDF at $IDF_PATH_V42, all other MCU variants (S2, S3, C3)
will be built using the IDF at $IDF_PATH_V44.

For the coverage build this reduces the binary size to about 1/4 of its
size, and seems to help gcov/lcov coverage analysis so that it doesn't miss
lines.

The methods duty_u16() and duty_ns() are implemented to match the existing
docs. The duty will remain the same when the frequency is changed.
Standard ESP32 as well as S2, S3 and C3 are supported.
Thanks to @kdschlosser for the fix for rounding in resolution calculation.
Documentation is updated and examples expanded for esp32, including the
quickref and tutorial. Additional notes are added to the machine.PWM docs
regarding limitations of hardware PWM.
Instead of board pins, so that pins which have only the CPU specified in
pins.csv can still be used with mp_hal_pin_config_alt_static().

A board can now define the following linker symbols to configure its flash
storage layout:
_micropy_hw_internal_flash_storage_start
_micropy_hw_internal_flash_storage_end
_micropy_hw_internal_flash_storage_ram_cache_start
_micropy_hw_internal_flash_storage_ram_cache_end
And optionally have a second flash segment by configuring
MICROPY_HW_ENABLE_INTERNAL_FLASH_STORAGE_SEGMENT2 to 1 and defining:
_micropy_hw_internal_flash_storage2_start
_micropy_hw_internal_flash_storage2_end

The third and fourth parameters in display.rect() and display.fill_rect()
are not x,y coordinates, but are instead width,height values. Update the
comment after the example to show the correct x,y coordinates of the bottom
right corner of each rectangle, respectively.
This reduces code size and code duplication, and fixes `pyb.usb_mode()` so
that it now returns the correct string when in multi-VCP mode (before, it
would return None when in one of these modes).

Frequency range 15Hz/18Hz to > 1 MHz, with decreasing resolution of the
duty cycle. The basic API is supported as documentated, except that
keyword parameters are accepted for both the instatiaton and the
PWM.init() call.
Extensions: support PWM for channel pairs. Channel pairs are declared by
supplying 2-element tuples for the pins. The two channels of a pair must
be the A/B channel of a FLEXPWM module. These form than a complementary
pair.
Additional supported keyword arguments:
- center=value Defines the center position of a pulse within the pulse
cycle. The align keyword is actually shortcut for center.
- sync=True|False: If set to True, the channels will be synchronized to a
submodule 0 channel, which has already to be enabled.
- align=PWM.MIDDLE | PMW.BEGIN | PWM.END. It defines, whether synchronized
channels are Center-Aligned or Edge-aligned. The channels must be either
complementary a channel pair or a group of synchronized channels. It may
as well be applied to a single channel, but withiout any benefit.
- invert= 0..3. Controls ouput inversion of the pins. Bit 0 controls the
first pin, bit 1 the second.
- deadtime=time_ns time of complementary channels for delaying the rising
slope.
- xor=0|1|2 xor causes the output of channel A and B to be xored. If
applied to a X channel, it shows the value oif A ^ B. If applied to an A
or B channel, both channel show the xored signal for xor=1. For xor=2,
the xored signal is split between channels A and B. See also the
Reference Manual, chapter about double pulses. The behavior of xor=2 can
also be achieved using the center method for locating a pulse within a
clock period.
The output is enabled for board pins only.
CPU pins may still be used for FLEXPWM, e.g. as sync source, but the signal
will not be routed to the output. That applies only to FLEXPWM pins. The
use of QTMR pins which are not board pins will be rejected.
As part of this commit, the _WFE() statement is removed from
ticks_delay_us64() to prevent PWM glitching during calls to sleep().
Any board with a board.json file will be built. Additional variants for
certain pyboards will also be built by the explicit build-stm32-extra.sh
script. Both .dfu and .hex files will be made available.
Also build boards in a sorted order, and don't stop building if a single
board fails.

This is to make the builds for all nucleo/discovery boards uniform, so they

Make it possible to proceed to a regular lookup in locals_dict if the
custom type->attr fails. This allows type->attr to extend rather than
completely replace the lookup in locals_dict.
This is useful for custom builtin classes that have mostly regular methods
but just a few special attributes/properties. This way, type->attr needs
to deal with the special cases only and the default lookup will be used for
generic methods.
