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. |
