After changing the bitstream implementation to use the RMT driver in
commit 72d86158121e32bbabaeade08f449d507bf40f9a
("esp32/machine_bitstream.c: Replace with RMT-based driver."), using
multiple `Neopixel` instances shows signal duplication between the
instances (i.e. a `write()` on one instance is written to all instances).
On invocation, the rmt driver configures the GPIO matrix to route the
output signal to the respective GPIO pin. When called for a different
`NeoPixel` instance using a different pin, the new route is established,
but the old route still exists. Now, the RMT output signal is sent to both
pins.
Fix this by setting the standard GPIO output function for the current pin
after uninstalling the RMT driver.

In commit 86ce442607 the '.frozen' entry was
added at the start of sys.path, to allow control over when frozen modules
are searched during import, and retain existing behaviour whereby frozen
was searched before the filesystem.
But Python semantics of sys.path require sys.path[0] to be the directory of
the currently executing script, or ''.
This commit moves the '.frozen' entry to second place in sys.path, so
sys.path[0] retains its correct value (described above).

Save and restore the same duty cycle when the frequency (or frequency
resolution) is changed. This allows a smooth frequency change.
Also update the esp32 PWM quickref to be clearer.
These removed ones are either unused by MicroPython or provided by osapi.h
in the SDK. In particular ets_delay_us() has different signatures for
different versions of the SDK, so best to let it provide the declaration.

The index of machine_hw_spi_obj and machine_hw_spi_default_pins arrays is
assigned to 0 for ARG_id==HSPI_HOST and 1 for another SPI. On ESP32S2 and
S3 HSPI_HOST=2 so the first set (idx=0) of default pins is used for
SPI(id=2) aka HSPI/SPI3 and the second set (idx=1) for SPI(id=1) aka
FSPI/SPI2. This makes a misleading mess in MICROPY_HW_SPIxxxx definitions
and it is also in contradiction to the comments around the definitions.
Change the test of ARG_id to fix the order of machine_hw_spi_default_pins.
This change might require adjusting MICROPY_HW_SPIxxxx definitions in
mpconfigboard.h of S2/S3 based boards.

- Move the qspi_xxxx_flash_config.c files to hal.
It turned out that they are less board than flash type specific.
- Change to a common flexspi_flash_config.h header file.
Thanks for the hint, Damien. The DEBUG build got very large recently.
The major difference is, that inline function are now inlined and
not included as a function. That's good and maybe bad. The good thing is,
that the code speed si now close to the final code. It could be worse
in single step debugging. I'll see.
Setting this option caused a new warning and a formatting error
to pop up at different places. Fixed as well.
The ID is read in a single function and used for:
- machine.unique_id()
- Ethernet MAC addresses.
- ...
That facilitates use of other MCU using a different access method for
the ID (e.g. i.MX RT1176).
Just another choice for the PHY interface.
Added: Keyword option phy_clock=LAN.IN or LAN.OUT
to define the source of the 50MHZ clock for the PHY
interface. The RMII clock is not enabled if it
is generated by a PYH board. Constants:
LAN.IN The clock is provided by the PHY board.
LAN.OUT The clock is provided by the MCU board.
The default is LAN.OUT or the value set in mpconfigboard.h, which
is currently set to IN only for the SEEED ARCH MIX board. Usage etc:
lan = LAN(phy_type=LAN.PHY_DP83848, phy_clock=LAN.IN)
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.

All 3 micros we care about (S2, S3, C3) state in the documentation
that DMA channel can be specified as SPI_DMA_CH_AUTO.
Specifying a specific DMA channel explicitly doesn't _ever_ work on
ESP32-S3, so no SPI bus could be used.
Testing performed: On the ESP32-S3-DevKitC, used neopixel_spi to
turn the onboard neopixel red, green, and blue
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().

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().
This targets the 64-bit CPU Raspberry Pis. The BCM2711 on the Pi 4
and the BCM2837 on the Pi 3 and Zero 2W. There are 64-bit fixes
outside of the ports directory for it.
There are a couple other cleanups that were incidental:
* Use const mcu_pin_obj_t instead of omitting the const. The structs
themselves are const because they are in ROM.
* Use PTR <-> OBJ conversions in more places. They were found when
mp_obj_t was set to an integer type rather than pointer.
* Optimize submodule checkout because the Pi submodules are heavy
and unnecessary for the vast majority of builds.

Because DMA2 may be in use by other peripherals, eg SPI1.
On PYBD-SF6 it's possible to trigger a bug in the existing code by turning
on WLAN and connecting to an AP, pinging the IP address from a PC and
running the following code on the PYBD:
def spi_test(s):
while 1:
s.write('test')
s.read(4)
spi_test(machine.SPI(1,100000000))
This will eventually fail with `OSError: [Errno 110] ETIMEDOUT` because
DMA2 was turned off by the CYW43 driver during the SPI1 transfer.
This commit fixes the bug by removing the code that explicitly disables
DMA2. Instead DMA2 will be automatically disabled after an inactivity
timeout, see commit a96afae90f
