IcedRooibos 7ea06a3e26 esp32/esp32_rmt: Fix looping behaviour for RMT on ESP32-S3.
The previous code worked on ESP32 but not ESP32-S3.  All the IDF (v4.4.3)
examples call rmt_set_tx_loop_mode before rmt_write_items, so make that
change here.

David (Pololu) bf3eb9dc39 rp2/machine_i2c: Add timeout parameter for machine.I2C().
This commit adds support for the `timeout` keyword argument to machine.I2C
on the rp2 port, following how it's done on other ports.

The main motivation here is avoid the interpreter crashing due to infinite
loops when SDA is stuck low, which is quite common if the board gets reset
while reading from an I2C device.

A default timeout of 50ms is chosen because it's consistent with:
- Commit a707fe50b0 which used a timeout of
  50,000us for zero-length writes on the rp2 port.
- The machine.SoftI2C class which uses 50,000us as the default timeout.
- The stm32 port's hardware I2C, which uses 50,000us for
  I2C_POLL_DEFAULT_TIMEOUT_US.

This commit also fixes the default timeout on the esp32 port to be
consistent with the above, and updates the documentation for machine.I2C to
document this keyword argument.

David Grayson c046b23ea2 shared/runtime/pyexec: Don't allow Ctrl+C to interrupt frozen boot code.
Helps prevent the filesystem from getting formatted by mistake, among other
things.  For example, on a Pico board, entering Ctrl+D and Ctrl+C fast many
times will eventually wipe the filesystem (without warning or notice).

Further rationale: Ctrl+C is used a lot by automation scripts (eg mpremote)
and UI's (eg Mu, Thonny) to get the board into a known state.  If the board
is not responding for a short time then it's not possible to know if it's
just a slow start up (eg in _boot.py), or an infinite loop in the main
application.  The former should not be interrupted, but the latter should.
The only way to distinguish these two cases would be to wait "long enough",
and if there's nothing on the serial after "long enough" then assume it's
running the application and Ctrl+C should break out of it.  But defining
"long enough" is impossible for all the different boards and their possible
behaviour.  The solution in this commit is to make it so that frozen
start-up code cannot be interrupted by Ctrl+C.  That code then effectively
acts like normal C start-up code, which also cannot be interrupted.

Note: on the stm32 port this was never seen as an issue because all
start-up code is in C.  But now other ports start to put more things in
_boot.py and so this problem crops up.

Damien George 38e7b842c6 ports: Implement simple write polling for stdout.
This is a best-effort implementation of write polling.  It's difficult to
do correctly because if there are multiple output streams (eg UART and USB
CDC) then some may not be writeable while others are.  A full solution
should also have a return value from mp_hal_stdout_tx_strn(), returning the
number of bytes written to the stream(s).  That's also hard to define.

The renesas-ra and stm32 ports already implement a similar best-effort
mechanism for write polling.

Fixes issue #11026.

Jim Mussared eb51ca4a11 esp32: Use extmod/modnetwork.c instead of port-specific version.
Rather than duplicating the implementation of `network`, this allows ESP32
to use the shared one in extmod.  In particular this gains access to
network.hostname and network.country.

Set default hostnames for various ESP32 boards.

Other than adding these two methods and the change to the default hostname,
there is no other user-visible change.

Damien Tournoud e982c1d8de esp32/network_lan: Add support for SPI-based ethernet chips.
Add support for various SPI-based ethernet chips (W5500, KSZ8851SNL,
DM9051) to the ESP32 port.  This leverages the existing support in ESP-IDF
for these chips -- which configures these chips in "MAC raw" mode -- and
the existing support for network.LAN in the ESP32 port.  In particular,
this doesn't leverage the wiznet5k support that is used on the rp2 and
stm32 ports (because that's for native use of lwIP).

Tested on the POE Featherwing (with the SJIRQ solder jumper bridged) and a
ESP32-S3 feather.

A note about the interrupt pin: The W5500 implementation within ESP-IDF
relies on hardware interrupt, and requires the interrupt pin from the W5500
to be wired to a GPIO.  This is not the case by default on the Adafruit
Ethernet FeatherWing, which makes it not directly compatible with this
implementation.

Mark Grosen 12f9948151 esp32/machine_i2c: Fix clocks and timeouts for ESP32-C3, ESP32-S3.
Each SoC family has its own clocks and timings/timeouts. For I2C, the
default source clock is either APB (ESP32, ESP32-S2) or XTAL (ESP32-S3,
ESP32-C3) as shown in the datasheets.  Since
machine_i2c.c/machine_hw_i2c_init() uses the default clk_flags (0), the
alternate low-power clock source is never selected in ESP-IDF
i2c.c/i2c_param_config().  There is not an API in i2c.c to get the source
clock frequency, so a compile-time value is used based on SoC family.

Also, the maximum timeout is different across the SoC families, so use the
I2C_LL_MAX_TIMEOUT constant to eliminate the warning from
i2c_set_timeout().

With these changes, the following results were obtained.  The I2C SCL
frequencies were measured with a Saleae logic analyzer.

ESP32 (TTGO T Dislay)
    I2C(0, scl=22, sda=21, freq=101781)  Measured: 100KHz
    I2C(0, scl=22, sda=21, freq=430107)  Measured: 400KHz
    I2C(0, scl=22, sda=21, freq=1212121) Measured: 941KHz

ESP32-S3 (TTGO T-QT)
    I2C(0, scl=34, sda=33, freq=111111)  Measured: 107KHz
    I2C(0, scl=34, sda=33, freq=444444)  Measured: 400KHz
    I2C(0, scl=34, sda=33, freq=1111111) Measured: 842KHz

Jim Mussared 6da41b5900 py/obj: Merge getiter and iternext mp_obj_type_t slots.
The goal here is to remove a slot (making way to turn make_new into a slot)
as well as reduce code size by the ~40 references to mp_identity_getiter
and mp_stream_unbuffered_iter.

This introduces two new type flags:
- MP_TYPE_FLAG_ITER_IS_ITERNEXT: This means that the "iter" slot in the
  type is "iternext", and should use the identity getiter.
- MP_TYPE_FLAG_ITER_IS_CUSTOM: This means that the "iter" slot is a pointer
  to a mp_getiter_iternext_custom_t instance, which then defines both
  getiter and iternext.

And a third flag that is the OR of both, MP_TYPE_FLAG_ITER_IS_STREAM: This
means that the type should use the identity getiter, and
mp_stream_unbuffered_iter as iternext.

Finally, MP_TYPE_FLAG_ITER_IS_GETITER is defined as a no-op flag to give
the default case where "iter" is "getiter".

Daniël van de Giessen 665f0e2a68 esp32: Sleep one tick in MICROPY_EVENT_POLL_HOOK.
If MicroPython threads are enabled, loops waiting for an incoming event
should release the GIL and suspend, allowing other tasks to run while they
wait.

Prior to this commit, the problem can easily be observed by running a
thread that is both busy and regularly releases the GIL (for example a loop
doing something then sleeping a few ms after each iteration).  When the
main task is at the REPL, the thread is significantly stalled.  If the main
task is manually made to release the GIL (for example, by calling
utime.sleep_ms(500)) the other thread can be seen immediately working at
the expected speed again.

Additionally, there are various instances in where blocking functions run
MICROPY_EVENT_POLL_HOOK in a loop while they wait for a certain event/
condition.  For example the uselect methods poll objects to determine
whether data is available, but uses 100% of CPU while it does, constantly
calling MICROPY_EVENT_POLL_HOOK in the process.

The MICROPY_EVENT_POLL_HOOK macro is only ever used in waiting loops, where
(if threads are enabled) it makes sense to yield for a single tick so that
these loops do not consume all CPU cycles but instead other threads may
execute.  (In fact, the thing these loops wait for may even indirectly or
directly depend on another task being able to run.)

This change moves the sleep that was inside the REPL input function to
inside the MICROPY_EVENT_POLL_HOOK macro, where the GIL is already being
released, solving both the blocking REPL issue and the 100% CPU use issue
at the same time.

Simon Baatz 79ae7098ca esp32/machine_bitstream: Fix signal duplication on output pins.
After changing the bitstream implementation to use the RMT driver in
commit 72d8615812
("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.

The index of machine_hw_spi_obj and machine_hw_spi_default_pins arrays is

Five tests have more than 3x speed up (200%+).

The performance of the tests bm_fft, bm_pidigits and misc_aes now scale
with CPU frequency (eg changing frequency to 240MHz boosts the performance
of these by 50%), which means they are no longer influenced by timing of
external flash access.  (The viper_call* tests did previously scale with
CPU frequency, and they still do.)

Turning off assertions reduces code size by about 80k, and going from -Os
to -O2 costs about 100k, so the net change in code size (for the GENERIC
board) is about +20k.

If a board wants to enable assertions, or use -Os instead of -O2, that's
still possible by overriding the sdkconfig parameters.

Damien George ea186de4c5 esp32: Split out WLAN code from modnetwork.c to network_wlan.c.
To match network_lan.c and network_ppp.c, and make it clear what code is
specifically for WLAN support.

Also provide a configuration option MICROPY_PY_NETWORK_WLAN which can be
used to fully disable network.WLAN (it's enabled by default).

Damien George f046b50ca5 esp32/main: Add option for a board to hook code into startup sequence.
To do this the board must define MICROPY_BOARD_STARTUP, set
MICROPY_SOURCE_BOARD then define the new start-up code.

For example, in mpconfigboard.h:

    #define MICROPY_BOARD_STARTUP board_startup
    void board_startup(void);

in mpconfigboard.cmake:

    set(MICROPY_SOURCE_BOARD
        ${MICROPY_BOARD_DIR}/board.c
    )

and in a new board.c file in the board directory:

    #include "py/mpconfig.h"

    void board_startup(void) {
        boardctrl_startup();
        // extra custom startup
    }

This follows stm32's boardctrl facilities.

leo chung 4fdf795efa esp32/mpthreadport: Fix TCB cleanup function so thread_mutex is ready.
Because vPortCleanUpTCB is called by the FreeRTOS idle task, and it checks
thread, but didn't check the thread_mutex.

And if thread is not NULL, but thread_mutex not ready then it will crash
with an error when calling mp_thread_mutex_lock(&thread_mutex, 1).

As suggested by @dpgeorge, move the thread = &thread_entry0 line to the end
of mp_thread_init().

IhorNehrutsa 52636fa692 esp32/machine_pwm: Add support for all PWM timers and channels.
This commit allows using all the available PWM timers (up to 8) and
channels (up to 16), without affecting the PWM API.

If a new frequency is set, first it checks if another timer is using the
same frequency.  If yes, then it uses this timer, otherwise, it creates a
new one.  If all timers are used, the user should set an already used
frequency, or de-init a channel.

This work is based on #6276 and #3608.

This commit refactors machine.PWM and creates extmod/machine_pwm.c.  The

the required PWM functionality.  This helps to reduce code duplication and
keep the same Python API across ports.

This commit does not make any functional changes.

Patrick Van Oosterwijck a66bd7a489 esp32/boards: Add GENERIC_C3_USB board with USB serial/JTAG support.
Add a new board type for ESP32-C3 revision 3 and up that implement the USB
serial/JTAG port on pin 18 and 19.  This variant uses the USB serial for
programming and console, leaving the UART free.

- Pins 18 and 19 are correctly reserved for this variant.  Also pins 14-17
  are reserved for flash for any ESP32-C3 so they can't be reconfigured
  anymore to crash the system.
- Added usb_serial_jtag.c and .h to implement this interface.
- Interface was tested to work correctly together with webrepl.
- Interface was tested to work correctly when sending and receiving
  large files with ampy.
- Disconnecting terminal or USB will not hang the system when it's
  trying to print.
