MicroPython 1.8.5 发布，该版本主要是加入了对Zephyr Project的支持（Zephyr Project是一个开源的RTOS）。 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 - vstr: remove vstr.had_error flag and inline basic vstr functions - objnone: use mp_generic_unary_op instead of custom one - showbc: make printf's go to the platform print stream - remove 'name' member from mp_obj_module_t struct - builtinimport: fix nanbox build after change to better handle -m modules - stream: remove unnecessary check for NULL return from vstr_extend - py.mk: suppress some compiler warnings when building berkeley-db - shrink mp_arg_t struct by using reduced-size integer members - update opcode format table because 3 opcodes were removed, 1 added - parse: only replace constants that are standalone identifiers - py.mk: add support for building modussl_mbedtls - only store the exception instance on Py stack in bytecode try block - vm: use MP_OBJ_FROM_PTR to cast a type to an object - modmicropython: add micropython.const, alias for identity function - objstr: remove unreachable function used only for terse error msgs - emitbc: remove/refactor unreachable code, to improve coverage - objfun: remove unnecessary check for viper fun with 5 or more args - objfun: use if instead of switch to check return value of VM execute - objset: use mp_check_self() to check args of set/frozenset methods - objset: ensure that use of frozenset.update raises an exception - compile: fix async-for/async-with to work with simpler exc on stack - scope: use lookup-table to determine a scope's simple name - scope: shrink scope_t struct by 1 machine word - scope: factor common code to find locals and close over them - compile: fix typo when checking for parse-node kind - argcheck: simplify if-chain so that the last one is the default - objbool: defer bool's unary op implementation to small int - objbool: make a slight simplification of bool constructor - modstruct: remove unreachable code, and add comment about CPy diff - add mp_raise_OSError(errno) helper function - objstringio: add readinto() method - modmicropython: add micropython.opt_level([value]) function - compile: remove unreachable code - mpz: in divmod, replace check for rhs!=0 with assert - mpz: use assert to verify mpz does not have a fixed digit buffer - factor duplicated function to calculate size of formatted int - objint: use size_t for arguments that measure bytes/sizes - compile: remove debugging code for compiler dispatch - lexer: remove unnecessary code, and unreachable code - vstr: combine vstr_new_size with vstr_new since they are rarely used - objdict: fix optimisation for allocating result in fromkeys - objdict: actually provide the key that failed in KeyError exception - use mp_raise_msg helper function where appropriate - add the module specified by -m to sys.modules as '__main__' 更多内容请查看官方完整版更新日志 下载地址： Source code (zip) Source code (tar.gz) MicroPython 1.8.5 发布，轻量级 Python 3 实现下载地址
