Testing performed: That the shipped .mpy files on a PyPortal (CP 4.x)
still work (play audio) with this branch, instead of erroring because
`WaveFile` can't be found in `audioio`.
Flash usage grew by 28 bytes. (I expected 24, there must be some other
effect on size/alignment that I didn't predict)
In #2013, @danh says:
My choice of where to put the semicolon is deliberate,
so that we can say
RUN_BACKGROUND_TASKS;
not have a redundant semicolon, and not confuse C code formatting.
.. such as namedtuple and attrtuple objects. This is the same
predicate used elsewhere in the file to check for adequate compatibility
between the types.
This was discovered due to crashing `time.time()` on the nrf port.
Closes: #2052
It is possible for this routine to expand some inputs, and in fact
it does for certan strings in the proposed Korean translation of
CircuitPython (#1858). I did not determine what the maximum
expansion is -- it's probably modest, like len()/7+2 bytes or
something -- so I tried to just make enc[] an adequate
over-allocation, and then ensured that all the strings in the
proposed ko.po now worked. The worst actual expansion seems to be a
string that goes from 65 UTF-8-encoded bytes to 68 compressed bytes
(+4.6%). Only a few out of all strings are reported as
non-compressed.
When nrf pwm audio is introduced, it will be called `audiopwmio`. To
enable code sharing with the existing (dac-based) `audioio`, factor
the sample and mixer types to `audiocore`.
INCOMPATIBLE CHANGE: Now, `Mixer`, `RawSample` and `WaveFile` must
be imported from `audiocore`, not `audioio`.
This also improves Palette so it stores the original RGB888 colors.
Lastly, it adds I2CDisplay as a display bus to talk over I2C. Particularly
useful for the SSD1306.
Fixes#1828. Fixes#1956
If a native displayio object is accessed before it's super().__init__()
has been called, then a placeholder is given that will cause a crash if
accessed. This is tricky to get right so we detect this case and raise
a NotInplementedError instead of crashing.
Fixes#1881
For both small and long integers, raise an exception if calling
struct.pack, adding an element to an array.array, or formatting an int
with int.to_bytes would overflow the requested size.
* Update pybadge pins and flash for rev D
* TileGrid now validates the type of the pixel_shader.
* Display actually handles incoming subclass objects.
* MicroPython will inspect native parents to see if special
accessors are used.
This fixes a crash on boards with built-in displays which statically
allocate the display bus. When the pointer is provided to never
free, it tries to allocate on the non-existant heap and crashes.

This changes a number of things in displayio:
* Introduces BuiltinFont and Glyph so the built in font can be used by libraries. For boards with
a font it is available as board.TERMINAL_FONT. Fixes#1172
* Remove _load_row from Bitmap in favor of bitmap[] access. Index can be x/y tuple or overall index. Fixes#1191
* Add width and height properties to Bitmap.
* Add insert and [] access to Group. Fixes#1518
* Add index param to pop on Group.
* Terminal no longer takes unicode character info. It takes a BuiltinFont instead.
* Fix Terminal's handling of [###D vt100 commands used when up arrowing into repl history.
* Add x and y positions to Group plus scale as well.
* Add bitmap accessor for BuiltinFont
This creates a common safe mode mechanic that ports can share.
As a result, the nRF52 now has safe mode support as well.
The common safe mode adds a 700ms delay at startup where a reset
during that window will cause a reset into safe mode. This window
is designated by a yellow status pixel and flashing the single led
three times.
A couple NeoPixel fixes are included for the nRF52 as well.
Fixes#1034. Fixes#990. Fixes#615.
The backtrace cannot be given because it relies on the validity
of the qstr data structures on the heap which may have been
corrupted.
In fact, it still can crash hard when the bytecode itself is
overwritten. To fix, we'd need a way to skip gathering the
backtrace completely.
This also increases the default stack size on M4s so it can
accomodate the stack needed by ASF4s nvm API.
This adds support for the OSError attributes : errno, strerror, filename and filename2.
CPython only sets errno if 2 arguments has been passed in. This has not been implemented here.
CPython OSError.args is capped at 2 items for backward compatibility reasons. This has not been
implemented here.
MICROPY_CPYTHON_COMPAT has to be enabled to get these attributes.
mp_common_errno_to_str() has been extended to check mp_errno_to_str() as well. This is done to ease
reuse for the strerror argument.
Add traceback chain to sys.exec_info()[2].
No actual frame info is added, but just enough to recreate the printed
exception traceback.
Used by the unittest module which collects errors and failures and prints
them at the end.
This gives access to the function underlying the bound method.
Used in the converted CPython stdlib logging.Formatter class to handle
overrriding a default converter method bound to a class variable.
The method becomes bound when accessed from an instance of that class.
I didn't investigate why CircuitPython turns it into a bound method.
This reverts commit 869024dd6e.
Ctrl-C stopped producing KeyboardInterrupt with this change on CircuitPython.
The Unix and stm32 ports handles Ctrl-C differently with a handler which is
probably why they where not affected.
Fixes#1092
