New rp2 port, BLE pairing, bonding and l2cap APIs, and docs on internals This release of MicroPython sees the addition of a new "rp2" port for the new Raspberry Pi RP2040 microcontroller, a dual-core Cortex-M0+ MCU with programmable IO. This port is built on the pico-sdk and MicroPython sits very close to the bare metal. The programmable IO is supported via the @rp2.asm_pio decorator which allows writing inline assembler to be run on the PIO state machines. The ubluetooth module has seen significant improvements, fixes and additions. BLE events are now synchronous on unix and stm32 so that user Python callbacks are called directly from the BLE stack (from NimBLE). This helps with the new pairing and bonding API. There is also a new l2cap API for much faster raw data transfer between BLE devices. Many new sections have been added to the existing "Developing and building MicroPython" chapter to make it all about the internals of MicroPython, including details about the MicroPython compiler, and how to port to a new system. This documentation work was done as part of Google's Season of Docs 2020. The native emitter and inline assembler now fully support ARMv6M, for Cortex-M0+ CPUs. There is also support added for C++ user modules on unix, stm32 and esp32. And reproducible builds can now be achieved by setting SOURCE_DATE_EPOCH in the shell build environment. Qstr preprocessing is now done in parallel to speed up building, and there is a new tools/ci.sh script with all functionality to run the continuous integration tests. The machine.I2C and machine.SPI classes have been modified so they no longer construct both software- and hardware-based peripheral instances. Such construction is now split to explicit soft and non-soft types by the introduction of machine.SoftI2C and machine.SoftSPI classes. See below for more information. The wait_for function in uasyncio now handles cancellation correctly, VfsLfs supports mounting in read-only mode, and the urandom module will randomise its seed on import on stm32, esp8266, esp32 and rp2 ports. A new raw-paste mode is added to the REPL which includes flow control between the device and host, as well as a mechanism where the device pulls in data from the host as it parses the input. This makes pasting code faster, more reliable and use less memory. This feature is supported on all ports that have a raw REPL and still supports previous REPL behaviour. See the documentation for more detail on this raw-paste mode. The stm32 port sees improved rfcore support for WB MCUs, including flash locking for writes when BLE is active, and a script for automatic update of FUS/WS firmware. New hooks are added for boards to configure the top level behaviour of the system in stm32_main, and there is now support for Ethernet on H7 processors. Mboot now allows signed and encrypted firmware updates. Breaking changes in this release are: - The "sys" module is renamed to "usys". Ports that do not enable module weak links must replace "import sys" with "import usys as sys". See commit 40ad8f1666b265dafc7844d765f45cfae4b6299f - machine.I2C and machine.SPI constructors are changed when using software-based I2C and SPI. Code that constructed I2C/SPI peripherals in the following way will need to be changed (or else their use will emit a warning which will eventually be an error): machine.I2C(-1, ...) -> machine.SoftI2C(...) machine.I2C(scl=scl, sda=sda) -> machine.SoftI2C(scl=scl, sda=sda) machine.SPI(-1, ...) -> machine.SoftSPI(...) machine.SPI(sck=sck, mosi=mosi, miso=miso) -> machine.SoftSPI(sck=sck, mosi=mosi, miso=miso) Code which uses machine.I2C and machine.SPI classes to access hardware peripherals does not need to change. See commits 39d50d129ce428858332523548f0594503d0f45b and 98182a97c5a9229938406beb722966eacceeb823 - In ubluetooth, the BLE.irq() method now has positional only arguments. See commit 6a6a5f9e151473bdcc1d14725d680691ff665a82 - In ubluetooth, arguments passed to the BLE.irq() callback that were previously bytes objects are now memoryview objects.

New uasyncio module, code formatting, BTstack bindings with unix support This release of MicroPython includes a new implementation of the uasyncio module which aims to be more compatible with CPython's asyncio module. The main change is to use a Task object for each coroutine, allowing more flexibility to queue tasks in various places, eg the main run loop, tasks waiting on events, locks or other tasks. It no longer requires pre-allocating a fixed queue size for the main run loop. A pairing heap is used to queue Tasks, and the core is optionally implemented in C. Most code in this repository is now auto-formatted using uncrustify for C code and Black for Python code. The tools/codeformat.py script is used to apply this formatting. Options for uncrustify were chosen to match as closely as possible the existing C style, but there were nevertheless quite a few changes to make the code style consistent. BlueKitchen BTstack bindings have been added for the ubluetooth module, as an optional alternative to the NimBLE stack. The unix port can now be built with BLE support using these bindings, which works with USB Bluetooth adaptors (this feature is enabled by default on the dev and coverage variants). Other Bluetooth additions include: new events for service/characteristic/ descriptor discovery complete; new events for read done and indicate acknowledgement; and support for active scanning in BLE.gap_scan(). See also below for breaking changes to the ubluetooth BLE API. PEP 526 has been implemented which adds new syntax for variable annotations, such as "x:int = 1". PEP 572 has also been implemented, which adds the ":=" operator for assignment expressions, such as "if x := 1:...". The whole code base now supports compressing error messages (those strings used as arguments to exception instances) using a "common word" scheme, which can be used to reduce code size. Other new features include: support for non-boolean results for equality and inequality tests; the addition of the micropython.heap_locked() function to test the state of the heap; binary operations for viper uint operands in the native emitter; and mtime support on littlefs v2 filesystems (which can be disabled if needed). There has been an important bug fix when importing ARM machine code from an .mpy file: the system now correctly tracks the executable memory allocated to the machine code so this memory is not reclaimed by the garbage collector. For testing, a multi-instance test runner has been added (see tests/run-multitests.py) which allows running a synchronised test across two or more MicroPython targets. This is currently used for network and BLE tests that require communication between multiple devices. In the unix port different builds are now organised into build variants, analogous to boards on bare-metal. And PEP 475 has been implemented which retries syscalls failing with EINTR. The stm32 port sees improved support for STM32WB MCUs, with ADC, SPI and DMA support, along with support in mboot for these MCUs. Mboot also adds optional littlefs support. The esp8266 port now includes three generic board definitions: GENERIC_512K, GENERIC_1M and GENERIC, with the latter for modules with 2M or more of flash. This port also changed the default filesystem to littlefs, and no longer supports hard pin IRQs. See breaking changes below for more details. The esp32 port now enables Bluetooth support (via NimBLE) on both IDF v3 and v4 builds. It also changes the default filesystem from FAT to littlefs v2 (but existing devices with FAT filesystems will continue to work without change). There is also a new mimxrt port which targets NXP i.MX RT series CPUs. Breaking changes in this release are: - async-for no longer await's on the result of __aiter__. The __aiter__ method should return an async-iterable object but is not itself awaitable. See commit 37e1b5c891f9964bb6c95228bc2d718511507a69 - In ubluetooth, the IRQ event constants have all changed value (from a bitfield to a sequential integer) and Python code should be updated accordingly by replacing the const definitions with the new ones, which can be found at https://docs.micropython.org/en/latest/library/ubluetooth.html#ubluetooth.BLE.irq See also commit e6881f08292d03f089185718c131f543d095089b - In ubluetooth, the IRQ data for the _IRQ_SCAN_RESULT event has had the "connectable" entry changed to "adv_type". The existing connectable value was a boolean and True now becomes 0x00, False becomes 0x02. See commit dd0bc26e65734b8a4fafa3769008e92e2ec6645d - For esp8266, the default filesystem has changed from FAT to littlefs v2. And the flash layout of the firmware and filesystem has changed to give more space to the firmware and frozen bytecode. When upgrading an existing esp8266 device the filesystem will be reformatted so files should be backed up first. See commit e0905e85a7ad2961aa9192f6130565860e531ad3 - For esp8266, machine.Pin no longer supports configuring a pin IRQ with "hard=True" (because the interrupt handling code is moved to iRAM). Existing code using pin IRQs should remove any "hard=True" argument. See commit 0bd58a56137bd9124756ed0f57b4213daccfc7d5 - For the unix port, binaries are renamed to micropython-variant (no longer micropython_variant).

v1.12
PYBD boards, BLE and littlefs, dynamic native modules, samd and powerpc This release sees a reduction in overall bytecode size due to compression of the bytecode prelude, saving 7 bytes of bytecode per function for roughly 80% of functions. The bytecode opcode values are also redefined to group them based on their argument size and format. Support is also added for the matrix multiplication operator "@" (PEP 465). The .mpy file format moved to version 5 to support the new bytecode encoding, and added support for relocation of native machine code, along with separate rodata and BSS sections. This allows a MicroPython system to import dynamic native modules, .mpy files that are generated from C code. Examples of this feature are provided in "examples/natmod/" and documentation in "docs/develop/natmod.rst". Some code-size saving optimisations were implemented leading to a reduction in size of minimal firmware: bare-arm reduced by 584 bytes, minimal x86 by 5476 bytes (partly due to changed compiler optimisation flags) and minimal ARM Thumb 2 by 1440 bytes (all measured with gcc 9.2.0). A new mechanism to freeze scripts into firmware is provided - a frozen manifest - whereby scripts to freeze are listed in a Python file (eg manifest.py). All ports are updated to use this new feature. When weak module links are enabled (via MICROPY_MODULE_WEAK_LINKS) an import will now automatically search for the built-in u-variant of a module if the non-u-variant fails (eg searches for "ufoo" if "foo" fails), so ports no longer provide an explicit list of these. The unix and windows ports now enable this feature. A performance benchmarking test suite is added which can be used to compare changes in absolute performance when optimising features, as well as compare across different ports. See "tests/run-perfbench.py". Bluetooth (BLE only) support is added via the "ubluetooth" module and provides the ability to implement the four BLE roles. The BLE stack is used is Mynewt Nimble and it currently runs on PYBD boards, STM32WB55 MCUs and ESP32 boards. Support for littlefs filesystems is added through the MicroPython VFS interface, and it works on the unix, stm32, esp8266 and esp32 ports. A new "machine.ADC.read_u16()" method is defined and implemented on stm32, esp8266, esp32 and nrf ports, providing a consistent way to read an ADC that returns a value in the range 0-65535. This new method should be preferred to the existing "ADC.read()" method. The stm32 port sees support for the new PYBD range of pyboards which include a fully integrated CYW43xx WiFi/BT chip. USB is enhanced to support VCP+MSC+HID mode and up to 3x simultaneous VCP interfaces. Support is also added for STM32WBxx MCUs including BLE. There is a new machine.ADC class which is compatible with other ports, along with a new machine.Timer class that implements a software timer with millisecond resolution and number of active timers only limited by RAM. Support for littlefs is available by default via uos.VfsLfs2. Documentation for using littlefs is found in "docs/reference/filesystem.rst". The esp8266 port has switched to use per-board configurations and builds, as well as the new frozen manifest feature. It also has optional littlefs support (requires a separate build). The esp32 port has the following new features: native code generation, machine.SDCard, hardware I2C, mDNS queries and responder, esp32.Partition, esp32.RMT, BLE (requires IDF v4), and built-in support for VfsLfs2. It has switched to use per-board configurations and builds, and frozen manifests. The default SSL output buffer is resized from 16kiB down to 4kiB to save RAM. There are new, minimal ports to Microchip SAMDxx microcontrollers, and the bare metal PowerPC architecture. A code-of-conduct based on the PSF's code is added in CODEOFCONDUCT.md. The following new Git submodules are added: mbedtls, asf4, tinyusb, mynewt-nimble. And a new third-party library: littlefs.

v1.11
Improved mpy format with support for native code, and new JavaScript port In this release the mpy file format has been moved to version 4 and has some significant improvements: mpy file size is reduced on average by about 35%, loading time of mpy files is reduced by about 40%, and they now have support to save native, viper and inline assembler code (or machine code generated from any other source). Size reduction of mpy files was achieved by adding a qstr window to reuse past qstrs when encoding them, by packing qstrs directly in the bytecode, and by defining a static qstr set. Some VM opcodes were also changed to fix a bug when doing a break/continue out of a finally block, and to make some simplifications. In particular POP_BLOCK and POP_EXCEPT opcodes were replaced with POP_EXCEPT_JUMP. Most uppercase macros have been converted to lowercase to make a more consistent C API, including all MP_OBJ_IS_xxx and MP_xxx_SLOT_IS_FILLED macros. The default PYTHON makefile variable is now changed from "python" to "python3", but Python 2 is still supported via "make PYTHON=python2". The mpy-cross compiler supports the new mpy version 4 and has new command line options: "-march=<arch>" to select the native emitter, and "--version" to print the MicroPython version and the mpy version. Also mpy-tool.py has support for freezing native code. A module system for external, user C modules has been implemented and documentation for this is available in the new "docs/develop" section. A new "javascript" port has been added which targets JavaScript as the machine via Emscripten. This allows to run MicroPython as an application within node.js, and to run it within a browser (among other things). All bare-metal ports have the following improvements: machine.sleep() is now machine.lightsleep(), and both lightsleep() and deepsleep() now take an optional argument which is the maximum time to sleep in milliseconds. These ports also now allow freezing of boot.py and main.py using the usual methods. And a new I2C method i2c.writevto(addr, vect) is added which can be used to write a tuple/list of buffers all at once to an I2C device. The stm32 port now has a fully integrated Ethernet MAC driver (see the network.LAN class) using lwIP for the TCP/IP stack, and sockets were made significantly more robust. Support for F413 MCUs was added. There are also some minor user-facing changes to this port: - machine.UART (and pyb.UART) now defaults to timeout=0 (was 1000ms) which gives UARTs a non-blocking behaviour. - The USB REPL is now configurable using uos.dupterm, and by default pyb.USB_VCP(0) is put on dupterm slot 1 before boot.py is executed. To disable the default REPL use: uos.dupterm(None, 1). - pyb.DAC(id) will now only reset the DAC the first time it is called; to get the old behaviour pass the bits parameter like: pyb.DAC(id, bits). - pyb.DAC.noise() and pyb.DAC.triangle() now output at full scale. - The system will not recreate boot.py if it's missing (it will only create it if the filesystem is corrupt, or when doing a factory reset). For the esp32 port, the build process has been updated to align better with the ESP IDF and now uses sdkconfig to configure features. Dual core mode is now enabled by default, SPIRAM is in memory-mapped mode so all of it can be used for the MicroPython heap, there is support to change the CPU frequency, and the WDT now panics and resets the device if it times out. A detailed list of changes follows. py core: - remove calls to file reader functions when these are disabled - add optional support for 2-argument version of built-in next() - compile: swap order of pop_block/pop_except in "except as" handler -

v1.10
Vast improvements to native emitter, new nrf port, unified documentation In this release there are a wide range of improvements and additions to both the core and the ports. In the core the main improvement was to the native emitter to have much more comprehensive support for general Python features, such as generators and complex exception handling, and the generated machine code is smaller and retains its efficiency. Elsewhere, fuzzy testing was used to find and eliminate some corner-case bugs, user classes were optimised when they don't use special accessors, underscores in numeric literals are now supported (PEP515), and the uio.IOBase class was added to allow user defined streams. For the extended modules there is now a VfsPosix filesystem component, a new ucryptolib module with AES support, addition of ure.sub() and of uhashlib.md5, and the lwIP socket implementation now has working TCP listen/accept backlog. Compared to the last release the minimal baseline core code size is reduced by about 2.2%, down by roughly 1500 bytes for bare-arm port and 3500 bytes for minimal x86 port. Most other ports have increased in size due to the addition of new features (eg ucryptolib, ure.sub). The stm32 port sees the introduction of a new bootloader -- mboot -- which supports DFU upload via USB FS, USB HS, as well as a custom I2C protocol, and also support to program external SPI flash. There is significant refactoring of the USB device driver, improved VCP throughput, and support for 2x VCP interfaces on the one USB device. lwIP has been integrated, and support added for SDRAM. Cortex-M0 CPUs are now supported along with STM32F0 MCUs. For the esp8266 port the heap is increased by 2kbytes, the radio is automatically put to sleep if no WLAN interfaces are active, and the UART can now be disconnected from the REPL and its RX buffer length configured. Upon soft-reset sockets are now cleaned up. The esp32 port has added support for external SPI RAM, PPPoS functionality, improved performance and stability when using threads, and other general bug fixes. There is a new nrf port for Nordic MCUs, currently supporting nRF51x and nRF52x chips. The docs have now been unified so there is just one set of documentation covering all ports. And initial documentation for the esp32 port is added. There are two changes at the Python API level that are not backwards with previous versions: - uos.dupterm now requires that a stream passed to it is derived from uio.IOBase (or is a native stream object). - The esp32 neopixel driver has had its default timing changed from 400kHz to 800kHz; existing code that didn't explicitly specify the "timing" parameter in the NeoPixel constructor may need to be updated to specify this as "timing=0" to get 400kHz timing.

v1.9.4
Parser size reduced, new Python stack, stm32 improvements, new esp32 port This release brings some significant size reductions to the parser, as well as removal of unused code and additional tests to improve coverage of the core. A new optional, internal Python stack is introduced for scoped allocation and can be used instead of alloca to provide more efficient and flexible temporary memory; see MICROPY_ENABLE_PYSTACK. There have been many improvements and internal code refactors of the stm32 port, and the port to the Espressif ESP32 SoC has been merged from its development repository. Compared to the last release the change in code size is (in bytes, using gcc 7.3): bare-arm: -1832 minimal x86: -2608 unix x64: -5129 unix nanbox: +1024 stm32: +2120 cc3200: -928 esp8266: +336 The decrease is mainly due to the reduced size of the parser, where the table of rule pointers was compressed to a table of offsets. The increase in the stm32 and esp8266 ports is due to additional features, such as more colour formats in the framebuf module and the addition of ujson.dump(). Code coverage (measured by gcov) has improved since the last version (v1.9.3 on the left, v1.9.4 on the right): py: 15202/15447 = 98.4% -> 15391/15513 = 99.2% extmod: 2227/ 2363 = 94.2% -> 2291/ 2430 = 94.3% Changes and additions seen by the Python user include: improvement of dir() and tab-completion to list all available attributes of an object; addition of efficient ucollections.deque type with fixed size; better handling and polling support of sockets that get into an error state; implementation of key and cert keyword arguments in ussl.wrap_socket (for axtls); uos.ilistdir now return 4-tuples with the file size in the fourth position. Changes at the C level include: removal of "make_qstr_if_not_already" argument from mp_obj_new_str; rename of mp_exc_recursion_depth to mp_raise_recursion_depth; removal of mp_const_MemoryError_obj; switching of stream close operation from method to ioctl; refactoring of how native emitter code is compiled with a file per architecture. The stm32 port has seen a lot of improvements and additions, as well as some significant internal refactoring to better support configuring custom boards. STM32F7 support is improved, USB HS is supported for F723 and F733, the CAN class has improvements to handle bus errors, ctrl-C can now interrupt running code when the REPL is over UART, and the ADC class added the read_timed_multi static method. Board configuration has seen some internal changes, in particular with setting LD_FILES, TEXT0_ADDR, and TEXT1_ADDR in mpconfigboard.mk (previously LD_FILE, FLASH_ADDR, TEXT_ADDR). The pin_X and pyb_pin_X identifiers have been changed to be pointers to objects rather than objects, and main is renamed to stm32_main.

v1.9.3
Introduction of ports subdirectory where all ports are moved to The main change in this release is the introduction of a "ports/" subdirectory at the top-level of the repository, and all of the ports are moved here. In the process the "stmhal" port is renamed to "stm32" to better reflect the MCU that it targets. In addition, the STM32 CMSIS and HAL sources are moved to a new submodule called "stm32lib". The bytecode has changed in this release, compared to the previous release, and as a consequence the .mpy version number has increased to version 3. This means that scripts compiled with the previous mpy-cross must be recompiled to work with this new version. There have also been various enhancements and optimisations, such as: check for valid UTF-8 when creating str objects, support for reverse special binary operations like __radd__, full domain checking in the math module, support for floor-division and modulo in the viper emitter, and addition of stack overflow checking when executing a regex. The stm32 port sees improved support for F7 MCUs, addition of a new board B_L475E_IOT01A based on the STM32L475, and support for the Wiznet W5500 chipset along with improved socket behaviour.

v1.9.2
Double precision math library and support on pyboard, and improved ussl This release brings general improvements and bug fixes to the core and various ports, as well as documentation additions, clean-ups and better consistency. And effort has been made to clean up the source code to make it more consistent across the core and all ports. There is a new tool "mpy_bin2res.py" to convert arbitrary (binary) files to Python resources for inclusion in source code (frozen or otherwise). The ussl module has seen improvements, including implementation of server_hostname (for axtls) and server_side mode (for mbedtls).

v1.9.1

v1.9
New VFS subsystem and scheduling framework, and less need for the heap This release adds some fundamental new components, allows for more Python operations without using the heap and has reduced code size and stack usage. Changes in the way iterators are handled allows to iterate without allocating on the heap for the types: tuple, list, str, bytes, bytearray, array, dict, set, frozenset. It also allows to call the builtins all, any, min max and sum without allocating heap memory for the iterator argument. And improvements to the handling of super() means that super().foo() method calls are now heap-less. A new generic VFS subsystem has been added which allows to mount arbitrary filesystems (even written in Python) at the root or at a mount-point within the root. The FatFS driver has been replaced with an object-oriented version (oofatfs) which allows a fully customisable filesystem layout. A scheduling framework has been implemented in the core which gives the ability to schedule callbacks to be called "as soon as possible". This allows ports to implement "soft IRQs" which allow the programmer to allocate memory during an interrupt handler, at the cost of some performance related to response time of the handler. The new micropython.schedule() function gives access to the scheduler. Other improvements to the core include: consts can now be big-nums, for example "X = const(1 << 100)"; addition of "help('modules')" to list available modules; stack usage reduced for a Python call by 8 bytes on ARM Cortex-M architectures; micropython.kbd_intr() function added to disable Ctrl-C capture; addition of uio.resource_stream(); mpy-cross is built automatically if needed; a helper tool mpy_cross_all.py is added to run mpy-cross on an entire project. The bytecode has changed in this version so existing .mpy files will need recompiling. There have also been some changes to the C API, most notably with mp_uint_t changed to size_t in many places. In the extended modules the following main changes have been made: addition of machine.Signal class to allow inversion on a Pin; framebuf has new formats of the form MONO_xxx; addition of uselect.ipoll() for allocation- free polling; addition of uos.ilistdir() for efficient iteration of a directory listing; machine.Pin high/low methods are renamed to on/off in esp8266 and zephyr (this is a backwards-incompatible change); machine.time_pulse_us() function no longer throws exceptions, but returns negative values instead. For stmhal the pyb.fault_debug() function is added, and default behaviour for a hard-fault is now an immediate reset. There is better support for F7 MCUs, in particular DMA and SD card support. A bug has been fixed with the USB VCP (USB serial) where it would in rare cases (usually when the host PC was under load) would lose characters. Pyboard now automatically mounts all available partitions on the SD card. Multithreading has been implemented and is available via the _thread module, but this feature is disabled by default and must be enabled at compile time using the MICROPY_THREAD and MICROPY_THREAD_GIL options. The ability to skip booting from SD card is now available by creating an empty file on the flash called "SKIPSD". The cc3200 port has had some backwards incompatible changes, in particular with I2C, Pin, UART and uos. Please see the documentation for the new behaviour. The esp8266 port has had a change in the size of the firmware in order to accommodate additional features. As such the filesystem for this version is incompatible with v1.8.7 and a device requires backup and erasure before flashing this version. Soft IRQs are now implemented for Pin and Timer callbacks, along with the general improvements described above. In the documentation there is now a section describing the differences between MicroPython and CPython. And code coverage is up to 98% across py/ and extmod/. Changes in code size (in bytes) between v1.8.7 and this version are: bare-arm: -1104 minimal: -1324 unix x64: -1115 unix nanbox: -11106 stmhal: +18116 cc3200: +1032 esp8266: +3060 Note that stmhal has increased significantly due to the addition of frozen bytecode and the LCD160CR driver.

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.

v1.8.6
ESP8266 port uses SDK 2.0, has more heap, has support for 512k devices This release brings some code size reductions to the core as well as more tests and improved coverage which is now at 94.3%. The time.ticks_diff(a, b) function has changed: the order of the arguments has been swapped so that it behaves like "a - b", and it can now return a negative number if "a" came before "b" (modulo the period of the ticks functions). For the ESP8266 port the Espressif SDK has been updated to 2.0.0, the heap has been increased from 28k to 36k, and there is support for 512k devices via "make 512k". upip is included by default as frozen bytecode. The network module now allows access-point reconnection without WiFi credentials, and exposes configuration for the station DHCP hostname. The DS18B20 driver now handles negative temperatures, and NeoPixel and APA102 drivers handle 4 bytes-per-pixel LEDs.

v1.8.5
New port to Zephyr, upip runs on baremetal, and reduction in code size This release adds a new port of MicroPython to run on top of the Zephyr real-time operating system. As part of this there is now basic support for using mbedTLS as the ussl module. The release also brings initial support for running the package manager upip on baremetal systems with low heap memory (such as esp8266), through a Python module interface. Work has been done in this release to clean up the core, removing redundant and/or unreachable code, and factoring existing duplicated code patterns. This brings a reduction of 828 bytes in code size to the bare-arm port, and 1368 bytes to the minimal port. There is also improved coverage through the addition of new tests for corner cases. The "micropython" module sees the addition of the "const" identity function which should be used as "from micropython import const" in scripts that want to use the MicroPython constant optimisations in the compile stage. There is also the addition of the "opt_level" function to change the parser/compiler optimisation level at runtime. The behaviour of "sys.exit" (and "raise SystemExit") on baremetal is now changed: this function no longer does a soft-reset of the board, rather it just stops the running script and drops to the REPL. In order to do an actual soft reset the "machine.soft_reset" function has been added (to the stmhal port only, for the time being). Following CPython, KeyError exceptions for dictionary lookups now have the failed key stored as the argument of the exception instance, accessible as exc.args[0]. The "ujson.load" function has also been added, to load JSON data from an arbitrary stream. The I2C support in the machine module now has clock stretching, the addition of the "addrsize" parameter in memory transfer methods, and I2C scanning now uses dummy writes instead of dummy reads to make the scanning more reliable. The CMSIS library has been upgrade to v4.30, and the boards section of the stmhal port has been refactored to use a common.ld script. The stmhal port now has a full implementation of the machine.SPI class, with support for both hardware SPI peripherals and fast software SPI. The USB HID driver in stmhal has added support to receive USB HID messages from the host. py core: - asmthumb: flush D-cache, and invalidate I-cache on STM32F7 - makeqstrdefs.py: use python 2.6 syntax for set creation - objnone: remove unnecessary handling of MP_UNARY_OP_BOOL - move frozen modules rules from esp8266 port for reuse across ports - combine 3 comprehension emit functions (list/dict/set) into 1 - combine 3 comprehension opcodes (list/dict/set) into 1 -

v1.8.4
Support for stream decompression in uzlib, and more ESP8266 features This release includes some bug fixes, code clean-up, updates to the docs, more tests, and various feature additions. The uzlib module now supports efficient stream decompression in the form of the uzlib.DecompIO class.

The stmhal port has ADC working on L4 microcontrollers, fixed initialisation for DAC, and addition of the machine.WDT class and machine.reset_cause function. For the ESP8266 port Pin(16) now works as an input pin and the hardware SPI peripheral is exposed as machine.SPI(1). The os.umount function is implemented and the port supports mounting of externally connected SD cards.

v1.8.2
Thread support, ESP8266 memory improvements, btree module, improved docs This release brings multi-threading support in the form of the _thread module, which closely matches the semantics of the corresponding CPython module. There is support for GIL and non-GIL builds; without the GIL enabled one must protect concurrent access to mutable Python state at the Python level using Lock objects. Threading with the GIL is enabled in the cc3200 port on the WiPy. Threading without the GIL is enabled on the unix port. The ESP8266 port has support for frozen bytecode (for scripts in the modules/ subdirectory), as well as optimisations for reduced memory usage and decreased memory fragmentation. The ESP8266 RTC also resumes correctly after a deepsleep. An initial "btree" module has been implemented for database support (unix port only), and the documentation has been further improved, with pre-built PDF versions of the docs now available. py core: - parse: treat constants that start with underscore as private - objdict: implemented OrderedDict equality check - support to build berkeley db 1.85 and "btree" module - mpconfig.h: MP_NOINLINE is universally useful, move from unix port -

v1.8
First general release of ESP8266 port, and support for frozen bytecode This release marks the first general release of official ESP8266 support within the MicroPython code base. The ESP8266 port has many improvements and additions, including: websocket and webrepl modules, deep-sleep mode, reading on UART, enhanced I2C support, enhanced network configuration, full sequence of start-up scripts (built-in _boot.py, boot.py and main.py), improved filesystem support with automatic flash-size detection as well as documentation and a tutorial. Known issues with ESP8266 port are: - Basic SSL support is available but it works only with relatively short data lengths (a few kilobytes). - WebREPL over SSL is not supported. - Only 5 or so WebREPL sessions in succession can be started (including file transfer sessions), after that the board requires a hard reset. - File transfer over WebREPL has issues with large files (above a few tens of kilobytes). - By design, only one concurrent WebREPL connection is supported. - Soft reset doesn't reset the network stack. In addition to ESP8266 support, this release brings frozen bytecode which allows to compile bytecode offline and link it into the firmware, completely eliminating the need for compilation (and the associated RAM usage) at runtime. Basic async/await syntax is now supported, and qstrs are now auto-generated in the build system. A detailed list of changes is given below. README: - explicitly point to required dependencies section - promote "docs" and "tests" to "major components" - mention support "async" keyword from Python 3.5 ACKNOWLEDGEMENTS: - add list of 842 backers from the ESP8266 campaign py core: -

v1.7
New MicroPython cross-compiler, and vastly improved ESP8266 port This release adds the MicroPython cross-compiler that can generate .mpy files (pre-compiled bytecode) which can be executed within any MicroPython runtime/VM. The ESP8266 port is also vastly improved thanks to a hugely successful Kickstarter campaign. This port now has an alternative event loop implementation to allow proper Berkeley sockets using lwIP built from source, and a greatly improved network module. Many extension modules are now enabled (ujson, ubinascii, uctypes, uhashlib, urandom, uheapq, ure, uzlib) and the machine module includes Timer, Pin, PWM, ADC, I2C, SPI, and basic UART. Bignums are supported, along with 30-bit precision floating point, and normal error messages. There is FatFS support and uos.dupterm. Many other improvements and bug fixes have been made to the core and other ports. The basic test suite can now run within a 16k heap. Inline assembler functions now support 4 arguments. The Unix port has the -i option to start the REPL after a script is finished. The stmhal port now exposes the flash and SD card as proper objects with the block protocol. There is support for generic STM32F439 boards, the NUCLEO-F411RE board, and targets to deploy via ST-LINK and OpenOCD. py core: - mpprint: fix sign extension when printf'ing %u, %x and %X - vm: fix popping of exception block in UNWIND_JUMP opcode -
