these are function prototypes not used in circuitpython. The
declarations began to conflict with ones in the upstream SDK
at some point, so delete them.
|
|
Recent vendor SDKs ship libs with code in .text section, which previously
was going into .irom0.text. Adjust the linker script to route these
sections back to iROM (follows upstream change).

This allows one to configure how a subsequent reset will behave and
also trigger a reset.
Fixes #350 and fixes #173

enable framebuf for ESP8266
|
|
For ESP8266, remove frozen module neopixel.py and add neopixel_write to mpconfigport.h. Use [Adafruit_CircuitPython_Neopixel/neopixel.py](https://github.com/adafruit/Adafruit_CircuitPython_NeoPixel) instead.

esp8266: Correct SPI functionality when write_value is provided.
|
|
|
|
It used to introduce extra clocks to the bus rather than changing the
value output.
This fixes SD cards.

Fixes #278, #277, #276, #275.

The frozen module `_boot.py` was not being loaded on restart
because `pyexec_frozen_module()` did not know about the new `.frozen`
pseudo-directory. Updated lower-level routine to look in the right place.
Also made ".frozen" and related values be `#define`s.

* Add microcontroller.cpu, the sole instance of microcontroller.Processor.
microcontroller.cpu.frequency is the clock frequency, in Hz.
microcontroller.cpu.temperature is the reading from the internal temperature sensor, in Celsius. None if not available.
* Squeeze firmware size by using -finline-limit. Otherwise non-Express builds were slightly too big.
* Update submodules.
* Fix documentation glitches

- Changed: ValueError, TypeError, NotImplementedError
- OSError invocations unchanged, because the corresponding utility
function takes ints, not strings like the long form invocation.
- OverflowError, IndexError and RuntimeError etc. not changed for now
until we decide whether to add new utility functions.

There were several different spellings of MicroPython present in comments,
when there should be only one.

WiFi mode selection happens on the level of individual interfaces.

Fix couple places in startup scripts that still had "import uos". This
would cause an exception when _boot.py was executed during startup.

This way it can be overridden by a socket module in Python, as in other
ports.

The code conventions suggest using header guards, but do not define how
those should look like and instead point to existing files. However, not
all existing files follow the same scheme, sometimes omitting header guards
altogether, sometimes using non-standard names, making it easy to
accidentally pick a "wrong" example.
This commit ensures that all header files of the MicroPython project (that
were not simply copied from somewhere else) follow the same pattern, that
was already present in the majority of files, especially in the py folder.
The rules are as follows.
Naming convention:
* start with the words MICROPY_INCLUDED
* contain the full path to the file
* replace special characters with _
In addition, there are no empty lines before #ifndef, between #ifndef and
one empty line before #endif. #endif is followed by a comment containing
the name of the guard macro.
py/grammar.h cannot use header guards by design, since it has to be
included multiple times in a single C file. Several other files also do not
need header guards as they are only used internally and guaranteed to be
included only once:
* MICROPY_MPHALPORT_H
* mpconfigboard.h
* mpconfigport.h
* mpthreadport.h
* pin_defs_*.h
* qstrdefs*.h

writeable and prevent USB from editing it.
|
|
py/builtin.h declares mp_builtin_open with the first argument of type
size_t. Make all implementations conform to this declaration.
|
|
also initializes in the same way where it takes from a true random
source when available through os.urandom(). After initializing, it
produces deterministic results until the seed is set.
This replaces urandom!
Fixes #139.

os is a subset of CPython's os. storage contains additional
file system mounting functionality based on UNIX's mount
management.

GC finalization should be enabled for modlwip, or it may lead to GC
problems with socket objects. This decreases usable heap size from
36288 to 35968 (-320) bytes.
|
|
It belongs with the other pin config functions in machine_pin.c. Also,
esp_mphal.c is put in iRAM so this change saves about 300 bytes of iRAM
(and mp_hal_pin_open_drain is not a time critical function so doesn't
need to be in iRAM).
|
|
No changes have been made to the code, the files just moved.

These drivers can now be used by any port (so long as that port has the
_onewire driver from extmod/modonewire.c).
These drivers replace the existing 1-wire and DS18X20 drivers in the
drivers/onewire directory. The existing ones were pyboard-specific and
not very efficient nor minimal (although the 1-wire driver was written in
pure Python it only worked at large enough CPU frequency).
This commit brings backwards incompatible API changes to the existing
1-wire drivers. User code should be converted to use the new drivers, or
check out the old version of the code and keep a local copy (it should
continue to work unchanged).
|
|
This follows naming scheme of other modules in extmod.
|
|
It's now generic enough to be used by any port.
|
|
The 1-wire bus is defined with fixed timings so there should be no need to
change them dynamically at runtime. Making the timings fixed saves about
270 bytes of code and 20 bytes of RAM.
|
|
The reason it was separated is so that the low-level code could be put in
iRAM, for timing reasons. But:
1. Tests show that it's not necessary to have this code in iRAM for it to
function correctly, and taking it out of iRAM reclaims some of that precious
resource. Furthermore, even though these functions were in iRAM there were
some functions that it called (eg pin get/set functions) which were not in
iRAM, so partially defeated the purpose of putting the 1-wire code in iRAM.
2. It's easier to reuse this 1-wire code in other ports if it's in a single
file.
3. If it turns out that certain code does need to be in iRAM then one can
use the MP_FASTCODE macro to do that.

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.

- 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"

- 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

Also, rename Direction.IN to Direction.INPUT and Direction.OUT to Direction.OUTPUT.
This simplifies using them. Prior to the nativeio split this would have led to
clutter in the top-level namespace but having digitalio prevents this.
Fixes #152
