Allows to translate C-level pin API to Python-level pin API. In other
words, allows to implement a pin class and Python which will be usable
for efficient C-coded algorithms, like bitbanging SPI/I2C, time_pulse,
etc.
|

| |
| |
| |
| | |
It's now used for more than just stream protocol (e.g. pin protocol), so
don't use false names.
|
| | |
| |
| |
| |
| | |
It has more usages than just qstr extraction, for example, embedding (where
people don't care about efficient predefined qstrs).
|
| | |
| |
| |
| | |
"lib" happened to be defined inside block conditional on $(PROG).
|
| | |
| |
| |
| |
| |
| | |
That's arbitrary restriction, in case of embedding, a source file path may
be absolute. For the purpose of filtering out system includes, checking
for ".c" suffix is enough.

Assignments of the form "_id = const(value)" are treated as private
(following a similar CPython convention) and code is no longer emitted
for the assignment to a global variable.

This reverts commit 1c0343f9d991c241d335712593f3a63858dc91b6.
Reason: to make merging simpler. This feature will anyway be provided by
master in a later version.

Many ESP8266 improvements, enhanced WebREPL, and support for STM32L4 MCUs
This release brings general improvements and bug fixes, and some new
features. There is now a uerror module for consistent errno handling
across ports, as well as textual names of OS errors that are printed when
an OSError is raised. There is support for frozen packages, via both
frozen scripts and frozen bytecode. WebREPL on the ESP8266 is greatly
improved with many bug fixes and now supports an unlimited (or very large)
number of reconnects. The os module on the ESP8266 now has rename, chdir,
getcwd and stat. The unix port now includes the ussl module by default.
The stmhal port has support for STM32L4 MCUs including the STM32L476
Discovery board and the LimiFrog board.

Since not all ports that enable the machine module have the pin HAL
functions.
|
| | |
| |
| |
| | |
The C implementation is taken from the DHT driver.

Using usual method of virtual method tables. Single virtual method,
ioctl, is defined currently for all operations. This universal and
extensible vtable-based method is also defined as a default MPHAL
GPIO implementation, but a specific port may override it with its
own implementation (e.g. close-ended, but very efficient, e.g. avoiding
virtual method dispatch).
|
| | |
| |
| |
| | |
Useful to check file/dir operations result, in particular used by upip.
|
| | |
| |
| |
| |
| | |
So the documentation's example works. Besides, a tuple can be more
memory efficient.
|
| | |
| |
| |
| |
| | |
When rendering the qstr for a C header file, the double-quate character
must be escaped.
|
| | |
| |
| |
| | |
Freezing mpy files using mpy-tool.py now works again.
|
| | | |
|
| | | |
|
| | |
| |
| |
| |
| |
| | |
Disabled by default, enabled in unix port. Need for this method easily
pops up when working with text UI/reporting, and coding workalike
manually again and again counter-productive.
|
| | | |
|
| | |
| |
| |
| |
| | |
These are workarounds required until frozen .mpy loading following standard
frozen modules code path.
|
| | |
| |
| |
| |
| |
| |
| |
| |
| |
| | |
Now frozen modules is treated just as a kind of VFS, and all operations
performed on it correspond to operations on normal filesystem. This allows
to support packages properly, and potentially also data files.
This change also have changes to rework frozen bytecode modules support to
use the same framework, but it's not finished (and actually may not work,
as older adhox handling of any type of frozen modules is removed).
|
| | |
| |
| |
| | |
Similar to existing mp_hal_delay_ms/mp_hal_ticks_ms.
|
| | | |
|
| | |
| |
| |
| |
| | |
Otherwise some compilers (eg without optimisation) will put this read-only
data in RAM instead of ROM.

Both read and write operations support variants where either a) a single
call is made to the undelying stream implementation and returned buffer
length may be less than requested, or b) calls are repeated until requested
amount of data is collected, shorter amount is returned only in case of
EOF or error.
These operations are available from the level of C support functions to be
used by other C modules to implementations of Python methods to be used in
user-facing objects.
The rationale of these changes is to allow to write concise and robust
code to work with *blocking* streams of types prone to short reads, like
serial interfaces and sockets. Particular object types may select "exact"
vs "once" types of methods depending on their needs. E.g., for sockets,
revc() and send() methods continue to be "once", while read() and write()
thus converted to "exactly" versions.
These changes don't affect non-blocking handling, e.g. trying "exact"
method on the non-blocking socket will return as much data as available
without blocking. No data available is continued to be signaled as None
return value to read() and write().
From the point of view of CPython compatibility, this model is a cross
between its io.RawIOBase and io.BufferedIOBase abstract classes. For
blocking streams, it works as io.BufferedIOBase model (guaranteeing
lack of short reads/writes), while for non-blocking - as io.RawIOBase,
returning None in case of lack of data (instead of raising expensive
exception, as required by io.BufferedIOBase). Such a cross-behavior
should be optimal for MicroPython needs.

It now supports \n, \r and \r\n as newline separators.
Adds 56 bytes to stmhal and 80 bytes to unix x86-64.
Fixes issue #1689.

Address printed was truncated anyway and in general confusing to outsider.
A line which dumps it is still left in the source, commented, for peculiar
cases when it may be needed (e.g. when running under debugger).
|
| | |
| |
| |
| |
| | |
'=' is pretty natural character for tail, and gives less dense picture
where it's easier to see what object types are actually there.
|
| | | |
|
| | |
| |
| |
| |
| |
| |
| |
| | |
OSError's are now printed like:
OSError: [Errno 1] EPERM
but only if the string corresponding to the errno is found.
|
| | |
| |
| |
| | |
Actual loading of .mpy files isn't tested.
|
| | |
| |
| |
| |
| |
| | |
In some compliation enviroments (e.g. mbed online compiler) with
strict standards compliance, <math.h> does not define constants such
as M_PI. Provide fallback definitions of M_E and M_PI where needed.
|
| | |
| |
| |
| |
| |
| |
| | |
If an OSError is raised with an integer argument, and that integer
corresponds to an errno, then the string for the errno is used as the
argument to the exception, instead of the integer. Only works if
the uerrno module is enabled.
|
| | | |
|
| | | |
|
| | | |
|

These are typical consumers of large chunks of memory, so it's useful to
see at least their number (how much memory isn't clearly shown, as the data
for these objects is allocated elsewhere).
