micropython升级到了 1.9.1，主要改进有：  
  
v1.9.1 修复了 stm32 的 USB 存储, lwIP 绑定和 VFS 问题  
  
This release provides an important fix for the USB mass storage device in  
the stmhal port by implementing the SCSI SYNCHRONIZE\_CACHE command, which  
is now require by some Operating Systems. There are also fixes for the  
lwIP bindings to improve non-blocking sockets and error codes. The VFS has  
some regressions fixed including the ability to statvfs the root.  
  
All changes are listed below.  
  
py core:  
\- modbuiltins: add core-provided version of input() function  
\- objstr: catch case of negative "maxsplit" arg to str.rsplit()  
\- persistentcode: allow to compile with complex numbers disabled  
\- objstr: allow to compile with obj-repr D, and unicode disabled  
\- modsys: allow to compile with obj-repr D and PY\_ATTRTUPLE disabled  
\- provide mp\_decode\_uint\_skip() to help reduce stack usage  
\- makeqstrdefs.py: make script run correctly with Python 2.6  
\- objstringio: if created from immutable object, follow copy on write policy  
  
extmod:  
\- modlwip: connect: for non-blocking mode, return EINPROGRESS  
\- modlwip: fix error codes for duplicate calls to connect()  
\- modlwip: accept: fix error code for non-blocking mode  
\- vfs: allow to statvfs the root directory  
\- vfs: allow "buffering" and "encoding" args to VFS's open()  
\- modframebuf: fix signed/unsigned comparison pendantic warning  
  
lib:  
\- libm: use isfinite instead of finitef, for C99 compatibility  
\- utils/interrupt\_char: remove support for KBD\_EXCEPTION disabled  
  
tests:  
\- basics/string\_rsplit: add tests for negative "maxsplit" argument  
\- float: convert "sys.exit()" to "raise SystemExit"  
\- float/builtin\_float\_minmax: PEP8 fixes  
\- basics: convert "sys.exit()" to "raise SystemExit"  
\- convert remaining "sys.exit()" to "raise SystemExit"  
  
unix port:  
\- convert to use core-provided version of built-in import()  
\- Makefile: replace references to make with $(MAKE)  
  
windows port:  
\- convert to use core-provided version of built-in import()  
  
qemu-arm port:  
\- Makefile: adjust object-file lists to get correct dependencies  
\- enable micropython.mem\_\*() functions to allow more tests  
  
stmhal port:  
\- boards: enable DAC for NUCLEO\_F767ZI board  
\- add support for NUCLEO\_F446RE board  
\- pass USB handler as parameter to allow more than one USB handler  
\- usb: use local USB handler variable in Start-of-Frame handler  
\- usb: make state for USB device private to top-level USB driver  
\- usbdev: for MSC implement SCSI SYNCHRONIZE\_CACHE command  
\- convert from using stmhal's input() to core provided version  
  
cc3200 port:  
\- convert from using stmhal's input() to core provided version  
  
teensy port:  
\- convert from using stmhal's input() to core provided version  
  
esp8266 port:  
\- Makefile: replace references to make with $(MAKE)  
\- Makefile: add clean-modules target  
\- convert from using stmhal's input() to core provided version  
  
zephyr port:  
\- modusocket: getaddrinfo: Fix mp\_obj\_len() usage  
\- define MICROPY\_PY\_SYS\_PLATFORM (to "zephyr")  
\- machine\_pin: use native Zephyr types for Zephyr API calls  
  
docs:  
\- machine.Pin: remove out\_value() method  
\- machine.Pin: add on() and off() methods  
\- esp8266: consistently replace Pin.high/low methods with .on/off  
\- esp8266/quickref: polish Pin.on()/off() examples  
\- network: move confusingly-named cc3200 Server class to its reference  
\- uos: deconditionalize, remove minor port-specific details  
\- uos: move cc3200 port legacy VFS mounting functions to its ref doc  
\- machine: sort machine classes in logical order, not alphabetically  
\- network: first step to describe standard network class interface  
  
examples:  
\- embedding: use core-provided KeyboardInterrupt object
