Fixes for stmhal USB mass storage, lwIP bindings and VFS regressions 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 |

Build Instructions for Teensy 3.1
Currently the Teensy 3.1 port of MicroPython builds under Linux and not under Windows.
The tool chain required for the build can be found at https://launchpad.net/gcc-arm-embedded.
Download the current Linux *.tar.bz2 file. Instructions regarding unpacking the file and moving it to the correct location as well as adding the extracted folders to the enviroment variable can be found at http://eliaselectronics.com/stm32f4-tutorials/setting-up-the-stm32f4-arm-development-toolchain/
In order to download the firmware image to the teensy, you'll need to use the downloader included with TeensyDuino. The following assumes that you have TeensyDuino installed and set the ARDUINO environment variable pointing to the where Arduino with TeensyDuino is installed.
cd teensy
ARDUINO=~/arduino-1.0.5 make
To upload micropython to the Teensy 3.1.
Press the Program button on the Teensy 3.1
sudo ARDUINO=~/arduino-1.0.5/ make deploy
Currently, the Python prompt is through the USB serial interface, i.e.
minicom -D /dev/ttyACM0
TIPS
Install 49-teensy.rules into /etc/udev/rules.d
If you install the 49-teensy.rules file from http://www.pjrc.com/teensy/49-teensy.rules
into your /etc/udev/rules.d folder then you won't need to use sudo:
sudo cp ~/Downloads/49-teensy.rules /etc/udev/rules.d
sudo udevadm control --reload-rules
Unplug and replug the teensy board, and then you can use: ARDUINO=~/arduino-1.0.5/ make deploy
Create a GNUmakefile to hold your ARDUINO setting.
Create a file call GNUmakefile (note the lowercase m) in the teensy folder with the following contents:
$(info Executing GNUmakefile)
ARDUINO=${HOME}/arduino-1.0.5
$(info ARDUINO=${ARDUINO})
include Makefile
GNUmakefile is not checked into the source code control system, so it will retain your settings when updating your source tree. You can also add additional Makefile customizations this way.
Tips for OSX
Set the ARDUINO environment variable to the location where Arduino with TeensyDuino is installed.
export ARDUINO=~/Downloads/Arduino.app/Contents/Java/
Search /dev/ for USB port name, which will be cu.usbmodem followed by a few numbers. The name of the port maybe different depending on the version of OSX. To access the Python prompt type:
screen <devicename> 115200
