主要改进：Improved mpy format with support for native code, and new JavaScript 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). 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 warning: support categories for warnings builtinhelp: only print help re FS modules if external import enabled downcase all MP_OBJ_IS_xxx macros to make a more consistent C API downcase MP_xxx_SLOT_IS_FILLED inline functions mkenv.mk: change default PYTHON variable from "python" to "python3" qstr: evaluate find_qstr only once then pass to Q_GET_HASH macro obj.h: remove obsolete mp_obj_new_fun_viper() declaration objfun: make fun_data arg of mp_obj_new_fun_asm() a const pointer eliminate warnings about unused arguments when debugging disabled compile: fix handling of unwinding BaseException in async with compile: add optimisation to compile OrderedDict inplace objexcept: fix hash of exc str created in mp_obj_new_exception_msg py.mk: update lwip build config to work with latest lwip version fix VM crash with unwinding jump out of a finally block vm: remove currently_in_except_block variable replace POP_BLOCK and POP_EXCEPT opcodes with POP_EXCEPT_JUMP persistentcode: add a qstr window to save mpy files more efficiently persistentcode: pack qstrs directly in bytecode to reduce mpy size persistentcode: define static qstr set to reduce size of mpy files add independent config for debugging sentinel object values emitnative: consolidate where HASCONSTS is set to load-const-obj fun emitnative: provide concentrated points of qstr emit emitnative: adjust accounting of size of const_table emitglue: remove union in mp_raw_code_t to combine bytecode & native add support to save native, viper and asm code to .mpy files persistentcode: bump .mpy version to 4 allow registration of modules at their definition implement a module system for external, user C modules update and rework build system for including external C modules move mp_native_type_from_qstr() from emitnative.c to nativeglue.c nativeglue: rename native convert funs to match other native helpers compile: add support to select the native emitter at runtime compile: support multiple inline asm emitters compile: check that arch is set when compiling native, viper or asm runtime: remove long-obsolete MICROPY_FSUSERMOUNT init code scheduler: convert micropythyon.schedule() to a circular buffer nlrthumb: add support for iOS where the C func is _nlr_push_tail makedefs: use io.open with utf-8 encoding when processing source runtime: optimise to not create temp float for int to power negative runtime: fix mp_unpack_ex so seq can't be reclaimed by GC during use mpprint: support printing %ld and %lu formats on 64-bit archs asmthumb: support asm_thumb code running on normal ARM processors native: improve support for bool type in viper functions remove "if (0)" and "if (false)" branches objgenerator: fix handling of None passed as 2nd arg to throw() objgenerator: remove unneeded forward decl and clean up white space misc.h: rename _MP_STRINGIFY to not use leading underscore in ident persistentcode: change "len" type to size_t for mp_obj_str_get_data objarray: add support for memoryview.itemsize attribute objarray: add decode method to bytearray update makefiles to use $(CAT) variable instead of hard coded "cat" update makefiles to use $(TOUCH) instead of hard coded "touch" extmod:
