F-strings, new machine.I2S class, ESP32-C3 support and LEGO_HUB_NO6 board
This release of MicroPython adds support for f-strings (PEP-498), with a
few limitations compared to normal Python. F-strings are essentially
syntactic sugar for "".format() and make formatting strings a lot more
convenient. Other improvements to the core runtime include pretty printing
OSError when it has two arguments (an errno code and a string), scheduling
of KeyboardInterrupt on the main thread, and support for a single argument
to the optimised form of StopIteration.
In the machine module a new I2S class has been added, with support for
esp32 and stm32 ports. This provides a consistent API for transmit and
receive of audio data in blocking, non-blocking and asyncio-based
operation. Also, the json module has support for the "separators" argument
in the dump and dumps functions, and framebuf now includes a way to blit
between frame buffers of different formats using a palette. A new,
portable machine.bitstream function is also added which can output a stream
of bits with configurable timing, and is used as the basis for driving
WS2812 LEDs in a common way across ports.
There has been some restructuring of the repository directory layout, with
all third-party code now in the lib/ directory. And a new top-level
directory shared/ has been added with first-party code that was previously
in lib/ moved there.
The docs have seen further improvement with enhancements and additions to
the rp2 parts, as well as a new quick reference for the zephyr port.
The terms master/slave have been replaced with controller/peripheral,
mainly relating to I2C and SPI usage. And u-module references have been
replaced with just the module name without the u-prefix to help clear up
the intended usage of modules in MicroPython.
For the esp8266 and esp32 ports, hidden networks are now included in WLAN
scan results. On the esp32 the RMT class is enhanced with idle_level and
write_pulses modes. There is initial support for ESP32-C3 chips with
GENERIC_C3 and GENERIC_C3_USB boards.
The javascript port has had its Makefile and garbage collector
implementation reworked so it compiles and runs with latest the Emscripten
using asyncify.
The mimxrt port sees the addition of hardware I2C and SPI support, as well
as some additional methods to the machine module. There is also support
for Hyperflash chips.
The nrf port now has full VFS storage support, enables source-line on
traceback, and has .mpy features consistent with other ports.
For the rp2 port there is now more configurability for boards, and more
boards added.
The stm32 port has a new LEGO_HUB_NO6 board definition with detailed
information how to get this LEGO Hub running stock MicroPython. There is
also now support to change the CPU frequency on STM32WB MCUs. And USBD_xxx
descriptor options have been renamed to MICROPY_HW_USB_xxx.

Support OSError attributes
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. |

Compress all translated strings with Huffman coding.
This saves code space in builds which use link-time optimization. The optimization drops the untranslated strings and replaces them with a compressed_string_t struct. It can then be decompressed to a c string. Builds without LTO work as well but include both untranslated strings and compressed strings. This work could be expanded to include QSTRs and loaded strings if a compress method is added to C. Its tracked in #531. |

Provide mp_errno_to_str even without uerrno
We can provide a basic version of mp_errno_to_str even if the uerrno module won't be provided. Rather than looking errno names up in the uerrno module's globals dict, we'll just rely on a simple mapping in the function itself. |

py/mperrno: Define MP_EWOULDBLOCK as EWOULDBLOCK, not EAGAIN.
Most modern systems have EWOULDBLOCK aliased to EAGAIN, ie they have the same value. But some systems use different values for these errnos and if a uPy port is using the system errno values (ie not the internal uPy values) then it's important to be able to distinguish EWOULDBLOCK from EAGAIN. Eg if a system call returned EWOULDBLOCK it must be possible to check for this return value, and this patch makes this now possible. |

all: Unify header guard usage.
The code conventions suggest using header guards, but do not define how those should look like and instead point to existing files. However, not all existing files follow the same scheme, sometimes omitting header guards altogether, sometimes using non-standard names, making it easy to accidentally pick a "wrong" example. This commit ensures that all header files of the MicroPython project (that were not simply copied from somewhere else) follow the same pattern, that was already present in the majority of files, especially in the py folder. The rules are as follows. Naming convention: * start with the words MICROPY_INCLUDED * contain the full path to the file * replace special characters with _ In addition, there are no empty lines before #ifndef, between #ifndef and one empty line before #endif. #endif is followed by a comment containing the name of the guard macro. py/grammar.h cannot use header guards by design, since it has to be included multiple times in a single C file. Several other files also do not need header guards as they are only used internally and guaranteed to be included only once: * MICROPY_MPHALPORT_H * mpconfigboard.h * mpconfigport.h * mpthreadport.h * pin_defs_*.h * qstrdefs*.h |

Support for Xtensa emitter and assembler, and upgraded F4 and F7 STM HAL This release adds support for the Xtensa architecture as a target for the native emitter, as well as Xtensa inline assembler. The int.from_bytes and int.to_bytes methods now require a second argument (the byte order) per CPython (only "little" is supported at this time). The "readall" method has been removed from all stream classes that used it; "read" with no arguments should be used instead. There is now support for importing packages from compiled .mpy files. Test coverage is increased to 96%. The generic I2C driver has improvements: configurable clock stretching timeout, "stop" argument added to readfrom/writeto methods, "nack" argument added to readinto, and write[to] now returns num of ACKs received. The framebuf module now handles 16-bit depth (generic colour format) and has hline, vline, rect, line methods. A new utimeq module is added for efficient queue ordering defined by modulo time (to be compatible with time.ticks_xxx functions). The pyboard.py script has been modified so that the target board is not reset between scripts or commands that are given on a single command line. For the stmhal port the STM Cube HAL has been upgraded: Cube F4 HAL to v1.13.1 (CMSIS 2.5.1, HAL v1.5.2) and Cube F7 HAL to v1.1.2. There is a more robust pyb.I2C implementation (DMA is now disabled by default, can be enabled via an option), and there is an implementation of machine.I2C with robust error handling and hardware acceleration on F4 MCUs. It is now recommended to use machine.I2C instead of pyb.I2C. The UART class is now more robust with better handling of errors/timeouts. There is also more accurate VBAT and VREFINT measurements for the ADC. New boards that are supported include: NUCLEO_F767ZI, STM32F769DISC and NUCLEO_L476RG. For the esp8266 port select/poll is now supported for sockets using the uselect module. There is support for native and viper emitters, as well as an inline assembler (with limited iRAM for storage of native functions, or the option to store code to flash). There is improved software I2C with a slight API change: scl/sda pins can be specified as positional only when "-1" is passed as the first argument to indicate the use of software I2C. It is recommended to use keyword arguments for scl/sda. There is very early support for over-the-air (OTA) updates using the yaota8266 project.

py/objexcept: Don't convert errno to str in constructor, do it in print.
OSError's are now printed like:
OSError: [Errno 1] EPERM
but only if the string corresponding to the errno is found.

py: Add mp_errno_to_str() and use it to provide nicer OSError msgs.
If an OSError is raised with an integer argument, and that integer corresponds to an errno, then the string for the errno is used as the argument to the exception, instead of the integer. Only works if the uerrno module is enabled. |
