e292296d52 py/objexcept: Remove optional TimeoutError exception.
TimeoutError was added back in 077812b2ab for
the cc3200 port. In f522849a4d the cc3200
port enabled use of it in the socket module aliased to socket.timeout.  So
it was never added to the builtins.  Then it was replaced by
OSError(ETIMEDOUT) in 047af9b10b.

The esp32 port enables this exception, since the very beginning of that
port, but it could never be accessed because it's not in builtins.

It's being removed: 1) to not encourage its use; 2) because there are a lot
of other OSError subclasses which are not defined at all, and having
TimeoutError is a bit inconsistent.

Note that ports can add anything to the builtins via MICROPY_PORT_BUILTINS.
And they can also define their own exceptions using the
MP_DEFINE_EXCEPTION() macro.

312c699491 esp32: Change from FAT to littlefs v2 as default filesystem.
This commit changes the default filesystem type for esp32 to littlefs v2.
This port already enables both VfsFat and VfsLfs2, so either can be used
for the filesystem, and existing systems that use FAT will still work.

This string is recognised by uncrustify, to disable formatting in the

to prevent modification of the strings within the Q(...).  In other places
it is used to prevent excessive reformatting that would make the code less

ad7213d3c3 py: Add mp_raise_msg_varg helper and use it where appropriate.
This commit adds mp_raise_msg_varg(type, fmt, ...) as a helper for

b72cb0ca1b py/mpthread.h: Use strong type for mp_thread_set_state() argument.
This modifies the signature of mp_thread_set_state() to use
mp_state_thread_t* instead of void*.  This matches the return type of
mp_thread_get_state(), which returns the same value.

`struct _mp_state_thread_t;` had to be moved before
`#include <mpthreadport.h>` since the stm32 port uses it in its
mpthreadport.h file.

4c93955b7b py/objslice: Add support for indices() method on slice objects.
Instances of the slice class are passed to __getitem__() on objects when
the user indexes them with a slice.  In practice the majority of the time
(other than passing it on untouched) is to work out what the slice means in
the context of an array dimension of a particular length.  Since Python 2.3
there has been a method on the slice class, indices(), that takes a
dimension length and returns the real start, stop and step, accounting for
missing or negative values in the slice spec.  This commit implements such
a indices() method on the slice class.

It is configurable at compile-time via MICROPY_PY_BUILTINS_SLICE_INDICES,
disabled by default, enabled on unix, stm32 and esp32 ports.

This commit also adds new tests for slice indices and for slicing unicode
strings.

799b6d1e0c extmod: Consolidate FAT FS config to MICROPY_VFS_FAT across all ports.
This commit removes the Makefile-level MICROPY_FATFS config and moves the
MICROPY_VFS_FAT config to the Makefile level to replace it.  It also moves
the include of the oofatfs source files in the build from each port to a
central place in extmod/extmod.mk.

For a port to enabled VFS FAT support it should now set MICROPY_VFS_FAT=1
at the level of the Makefile.  This will include the relevant oofatfs files
in the build and set MICROPY_VFS_FAT=1 at the C (preprocessor) level.

4be316fb07 esp32/moduos: Enable uos.VfsLfs2 for littlefs filesystems.
This commit adds support for littlefs (v2) on all esp32 boards.

The original FAT filesystem still works and any board with a preexisting
FAT filesystem will still work as normal.  It's possible to switch to
littlefs by reformatting the block device using:

    import uos, flashbdev
    uos.VfsLfs2.mkfs(flashbdev.bdev)

Then when the board reboots (soft or hard) the new littlefs filesystem will
be mounted.  It's possible to switch back to a FAT filesystem by formatting
with uos.VfsFat.mkfs(flashbdev.bdev).

f301170c7c esp32/machine_hw_spi: Fix exception msg when host is already in use.
When a SPI bus is initialized with a SPI host that is currently in use the
exception msg incorrectly indicates "SPI device already in use".  The
mention of "device" in the exception msg is confusing because the error is
about trying to use a SPI host that is already claimed.  A better exception
msg is "SPI host already in use".

b02d7e612d extmod/modbluetooth: Rename module to "ubluetooth".

d2384efa80 py: Automatically provide weak links from "foo" to "ufoo" module name.
This commit implements automatic module weak links for all built-in
modules, by searching for "ufoo" in the built-in module list if "foo"
cannot be found.  This means that all modules named "ufoo" are always
available as "foo".  Also, a port can no longer add any other weak links,
which makes strict the definition of a weak link.

It saves some code size (about 100-200 bytes) on ports that previously had
lots of weak links.

Some changes from the previous behaviour:
- It doesn't intern the non-u module names (eg "foo" is not interned),
  which saves code size, but will mean that "import foo" creates a new qstr
  (namely "foo") in RAM (unless the importing module is frozen).
- help('modules') no longer lists non-u module names, only the u-variants;
  this reduces duplication in the help listing.

Weak links are effectively the same as having a set of symbolic links on
the filesystem that is searched last.  So an "import foo" will search
built-in modules first, then all paths in sys.path, then weak links last,
importing "ufoo" if it exists.  Thus a file called "foo.py" somewhere in
sys.path will still have precedence over the weak link of "foo" to "ufoo".

8ba963cfa3 tools/makemanifest.py: Eval relative paths w.r.t. current manifest file.
When loading a manifest file, e.g. by include(), it will chdir first to the
directory of that manifest.  This means that all file operations within a
manifest are relative to that manifest's location.

As a consequence of this, additional environment variables are needed to
find absolute paths, so the following are added: $(MPY_LIB_DIR),
$(PORT_DIR), $(BOARD_DIR).  And rename $(MPY) to $(MPY_DIR) to be
consistent.

Existing manifests are updated to match.

96008ff59a esp32: Support building with ESP IDF 4.0-beta1.
This commit adds support for a second supported hash (currently set to the
4.0-beta1 tag).  When this hash is detected, the relevant changes are
applied.

This allows to start using v4 features (e.g. BLE with Nimble), and also
start doing testing, while still supporting the original, stable, v3.3 IDF.

Note: this feature is experimental, not well tested, and network.LAN and
network.PPP are currently unsupported.

31de44775c esp32: Add VFS FAT partition to partitions.csv and mount it as the FS.
This patch uses the newly-added esp32.Partition class to replace the
existing FlashBdev class.  Partition objects implement the block protocol
so can be directly mounted via uos.mount().  This has the following
benefits:

- allows the filesystem partition location and size to be specified in
  partitions.csv, and overridden by a particular board
- very easily allows to have multiple filesystems by simply adding extra
  entries to partitions.csv
- improves efficiency/speed of filesystem operations because the block
  device is implemented fully in C
- opens the possibility to have encrypted flash storage (since Partitions
  can be encrypted)

Note that this patch is fully backwards compatible: existing filesystems
remain untouched and work with this new code.

af5c998f37 py/modmath: Implement math.isclose() for non-complex numbers.
As per PEP 485, this function appeared in for Python 3.5.  Configured via
MICROPY_PY_MATH_ISCLOSE which is disabled by default, but enabled for the
ports which already have MICROPY_PY_MATH_SPECIAL_FUNCTIONS enabled.

MICROPY_HW_ENABLE_MDNS_QUERIES and/or MICROPY_HW_ENABLE_MDNS_RESPONDER to
0.  The hostname for the responder is currently taken from
tcpip_adapter_get_hostname() but should eventually be configurable.

b6906fa573 esp32/network_ppp: Add authentication support to the PPP interface.
This commit adds the connect() method to the PPP interface and requires
that connect() be called after active(1).  This is a breaking change for
the PPP API.

With the connect() method it's now possible to pass in authentication
information for PAP/CHAP, eg:

    ppp.active(1)
    ppp.connect(authmode=ppp.AUTH_PAP, username="user", "password="password")

If no authentication is needed simply call connect() without any
parameters.  This will get the original behaviour of calling active(1).

995f9cfdfc esp32: Pin MicroPython tasks to a specific core.
On this port the GIL is enabled and everything works under the assumption
of the GIL, ie that a given task has exclusive access to the uPy state, and
any ISRs interrupt the current task and therefore the ISR inherits
exclusive access to the uPy state for the duration of its execution.

If the MicroPython tasks are not pinned to a specific core then an ISR may
be executed on a different core to the task, making it possible for the
main task and an ISR to execute in parallel, breaking the assumption of the
GIL.

The easiest and safest fix for this is to pin all MicroPython related code
to the same CPU core, as done by this patch.  Then any ISR that accesses
MicroPython state must be registered from a MicroPython task, to ensure it
is invoked on the same core.

See issue #4895.

as machine.SDCard and using it can be as simple as:

    uos.mount(machine.SDCard(), '/sd')

de76f73d34 esp32/machine_timer: Reuse Timer handles, deallocate only on soft-reset.
The patch solves the problem where multiple Timer objects (e.g. multiple
Timer(0) instances) could initialise multiple handles to the same internal
timer.  The list of timers is now maintained not for "active" timers (where
init is called), but for all timers created.  The timers are only removed
from the list of timers on soft-reset (machine_timer_deinit_all).

Fixes #4078.

0557f0b74b esp32/network_ppp: Add a timeout for closing PPP connection.
This also fixes deleting the PPP task, since eTaskGetState() never returns
eDeleted.

A limitation with this patch: once the PPP is deactivated (ppp.active(0))
it cannot be used again. A new PPP instance must be created instead.

fbd4e61e57 esp32/machine_wdt: Add timeout arg to select interval, make WDT panic.
The machine.WDT() now accepts the "timeout" keyword argument to select the
WDT interval.  And the WDT is changed to panic mode which means it will
reset the device if the interval expires (instead of just printing an error
message).

0646e607b5 ports: Convert to use pyexec_file_if_exists() to execute boot/main.py.
The stm32 and nrf ports already had the behaviour that they would first
check if the script exists before executing it, and this patch makes all
other ports work the same way.  This helps when developing apps because
it's hard to tell (when unconditionally trying to execute the scripts) if
the resulting OSError at boot up comes from missing boot.py or main.py, or
from some other error.  And it's not really an error if these scripts don't
exist.

673db939b5 esp32/machine_pin: Rework pull mode config to fix GPIO hold feature.

esp_wifi_connect will return ESP_OK for the normal path of execution which

In such a case wifi.isconnected() should return False until the
reconnection is complete.  After reconnect a GOT_IP event is called and it
will change wifi_sta_connected back to True.

Replaces "PYB: soft reboot" with "MPY: soft reboot", etc.

Having a consistent prefix across ports reduces the difference between

3d49b157b8 esp32: Update to latest ESP IDF using sdkconfig and new ldgen procedure.
Configuration for the build is now specified using sdkconfig rather than
sdkconfig.h, which allows for much easier configuration with defaults from
the ESP IDF automatically applied.  sdkconfig.h is generated using the new
ESP IDF kconfig_new tool written in Python.  Custom configuration for a
particular ESP32 board can be specified via the make variable SDKCONFIG.

The esp32.common.ld file is also now generated using the standard ESP IDF
ldgen.py tool.

f59904f799 esp32/Makefile: Put all IDF compenents in .a libs to use IDF ld script.
When the ESP IDF builds a project it puts all separate components into
separate .a library archives.  And then the esp32.common.ld linker script
references these .a libraries by explicit name to put certain object files
in iRAM.

This patch does a similar thing for the custom build system used here,
putting all IDF .o's into their respective .a.  So a custom linker script
is no longer needed.

e7ab475276 esp32: Don't put py/scheduler.o in iRAM, it's no longer needed.
ISR's no longer need to be in iRAM, and the ESP IDF provides an option to
specify that they are in iRAM if an application needs lower latency when
handling them.  But we don't use this feature for user interrupts: both
timer and gpio ISR routines are registered without the ESP_INTR_FLAG_IRAM
option, and so the scheduling code no longer needs to be in iRAM.

eb446ec227 esp32/Makefile: Use system provided math library rather than uPy one.
The ESP IDF system already provides a math library, and that one is likely
to be better tuned to the Xtensa architecture.  The IDF components are also
tested against its own math library, so best not to override it.  Using the
system provided library also allows to easily switch to double-precision
floating point by changing MICROPY_FLOAT_IMPL to MICROPY_FLOAT_IMPL_DOUBLE.

485514f57a esp32: Allocate task TCB and stack from system heap not uPy heap.
This is necessary for two reasons: 1) FreeRTOS still needs the TCB data
structure even after vPortCleanUpTCB has been called, so this latter hook
function cannot free the TCB, and there is no where else to safely delete
it (this behaviour has changed recently in the ESP IDF); 2) when using
external SPI RAM the uPy heap is in this external memory but the task stack
must be allocated from internal SRAM.

c3c914f4dd esp8266,esp32: Implement high-res timers using new tick_hz argument.
machine.Timer now takes a new argument in its constructor (or init method):
tick_hz which specified the units for the period argument.  The period of
the timer in seconds is: period/tick_hz.

For backwards compatibility tick_hz defaults to 1000.  If the user wants to
specify the period (numerator) in microseconds then tick_hz can be set to
1000000.  The user can also specify a period of an arbitrary number of
cycles of an arbitrary frequency using these two arguments.

An additional freq argument has been added to allow frequencies to be

14ab81e87a esp32: Reduce latency for handling of scheduled Python callbacks.
Prior to this patch there was a large latency for executing scheduled
callbacks when when Python code is sleeping: at the heart of the
implementation of sleep_ms() is a call to vTaskDelay(1), which always
sleeps for one 100Hz tick, before performing another call to
MICROPY_EVENT_POLL_HOOK.

This patch fixes this issue by using FreeRTOS Task Notifications to signal
the main thread that a new callback is pending.

039f196c56 esp32/modnetwork: Fix isconnected() when using static IP config.
Currently <WLAN>.isconnected() always returns True if a static IP is set,
regardless of the state of the connection.

This patch introduces a new flag 'wifi_sta_connected' which is set in
event_handler() when GOT_IP event is received and reset when DISCONNECTED
event is received (unless re-connect is successful).  isconnected() now
simply returns the status of this flag (for STA_IF).

The pre-existing flag misleadingly named 'wifi_sta_connected" is also
renamed to 'wifi_sta_connect_requested'.

a90124a9e2 esp32: Add support for building with external SPI RAM.
This patch adds support for building the firmware with external SPI RAM
enabled.  It is disabled by default because it adds overhead (due to
silicon workarounds) and reduces performance (because it's slower to have
bytecode and objects stored in external RAM).

To enable it, either use "make CONFIG_SPIRAM_SUPPORT=1", or add this line
to you custom makefile/GNUmakefile (before "include Makefile"):

    CONFIG_SPIRAM_SUPPORT = 1

When this option is enabled the MicroPython heap is automatically allocated
in external SPI RAM.

The esp8266 uses modlwip.c for its usocket implementation, which allows to
easily support callbacks on socket events (like when a socket becomes ready
for reading).  This is not as easy to do for the esp32 which uses the
ESP-IDF-provided lwIP POSIX socket API.  Socket events are needed to get
WebREPL working, and this patch provides a way for such events to work by
explicitly polling registered sockets for readability, and then calling the
associated callback if the socket is readable.

cf31d384f1 py/stream: Switch stream close operation from method to ioctl.
This patch moves the implementation of stream closure from a dedicated
method to the ioctl of the stream protocol, for each type that implements
closing.  The benefits of this are:

1. Rounds out the stream ioctl function, which already includes flush,
   seek and poll (among other things).

2. Makes calling mp_stream_close() on an object slightly more efficient
   because it now no longer needs to lookup the close method and call it,
   rather it just delegates straight to the ioctl function (if it exists).

3. Reduces code size and allows future types that implement the stream
   protocol to be smaller because they don't need a dedicated close method.

Code size reduction is around 200 bytes smaller for x86 archs and around
30 bytes smaller for the bare-metal archs.

78302f7bb2 esp32/modesp: Add osdebug() function to disable or change IDF logging.
Code lineage:
osdebug() is based loosely on the version in esp8266, but there didn't
seem to be an obvious way of choosing a particular UART. The basic
behavior is the same, though: provide None, and logging is disabled;
provide an integer and logging is restored to the default level.

To build on that, and because the IDF provides more functionality, a
second parameter has now been implemented which allows the active log
level to be set:

   esp.osdebug(uart[, level])

The module has a corresponding set of LOG_ values to set this accordingly.

  esp32: Add PWM support via machine.PWM class.

  Code lineage:
  I started by copying the esp8266 machine_pwm.c. I used information from the
  ESP32 Technical Reference Manual, the esp-idf documentation, and the SDK's
  sample ledc example code (but I did not copy that code, just studied it to
  understand the SDK's API for PWM). So aside from the code copied from the
  esp8266 PWM support, everything else you see is just new code I wrote.

  I wasn't an employee of anybody when I wrote it, and I wrote it with the
  understanding and intention that it's simply a derivative work of the
  existing micropython code. I freely and willingly contribute it to the
  project and intend that it not change the legal status of the micropython
  code base in any way, even if it is included in that base in whole or part.
