The parameter order in the example for ticks_diff was incorrect. If it's
"too early" that means that scheduled time is greater than current time and
if it's "running late" then scheduled time would be less than current time.
Put offset first in OR expressions, and use "offset" var instead of
hardcoded numbers. Hopefully, this will make it more self-describing
and show patterns better.
State that this doc describes generic, "core" MicroPython functionality,
any particular port may diverge in both directions, by both omitting
some functionality, and adding more, both cases described outside the
generic documentation.
Describe that the only portable way to deal with addresses is by using
getaddrinfo(). Describe that some ports may support tuple addresses using
"socket" module (vs "usocket" of native MicroPython).
This clarifies return values and the handling of invalid (e.g. newline)
characters.
Encoding conforms to RFC 3548, but decoding does not, as it ignores invalid
characters in base64 input. Instead, it conforms to MIME handling of base64
(RFC 2045).
Note that CPython doesn't document handling of invalid characters in
a2b_base64() docs:
https://docs.python.org/3/library/binascii.html#binascii.a2b_base64 , so
we specify it more explicitly than it, based on CPython's actual behavior
(with which MicroPython now compliant).
This makes top-level ToC of the pyboard docs consistent with other ports
(consisting of 3 chapters: QuickRef, General Info, and Tutorial).
Also, some other minor tweaks applied, like local ToC for General Info and
headings mentioning pyboard.
This pseudo-section causes artifacts with latexpdf generation (almost
empty page with list containing literal "genindex", "modeindex", "search"
items). For HTML docs, these sections can be accessed from "home" page.
We don't use alpha/beta/RC, so for us version and release should be the
same, or it leads to confusion (for example, current, 1.9.1 docs are
marked as 1.9 at places).
The idea is to allow to define a kind of "macros" for repeatitive text,
so all occurrances can be updated in one place. Unfortunately, RST doesn't
support replacements with arguments, which limits usefulness of them and
should be taken into account.
We have enough terms or references throughout the docs which may be not
immediately clear or have some important nuances. Referencing terms in
gloassary is the best way to deal with that.
The old intro talked about "differences", but there were hardly any
sections describing differences, mostly MicroPython specific features.
On the other hand, we now have real "differences" chapter, though it's
mostly concerned with stdlib differences.
So, try to avoid confusion by changing wording and linking to the other
chapters and contrasting them with what is described in "MicroPython
language".
Previously, only "selected chapters" were shown in left-pane ToC (of
Read The Docs theme). These chapters were selected out of order. The
rest of chapters were hidden beyond "Documentation Contents" pseudo-
chapter. This arguably led only to confusion, as many people probably
never tried to open that pseudo-chapter, and those who did, were
confused. Such organization is even worse for PDF output, causing
chapters go in mix-mashed order.
So, instead move to single clean ToC. This will allow readers of HTML
to have access to any doc content at their fingertips (and straight
before their eyes), and will allow to finally have clean PDF docs.
Move hardware-specific optimizations to the very end of document, and
add visible note that it gives an example for Pyboard. Remove references
to specific hardware technologies, so the doc can be more naturally
used across ports. Various markup updates to adhere to the latest
docs conventions.
This causes `symbol` syntax to be equivalent to :any:`symbol`, which is
in turn the easiest way to cross-reference an arbitrary symbol in the
docs:
http://www.sphinx-doc.org/en/stable/markup/inline.html#role-any
:any: requires at least Sphinx 1.3 (for reference, Ubuntu 16.03 ships
with 1.3.6, the latest 1.6.3).
Any many of our docs, `symbol` is misused to specify arguments to
functions, etc. Refactoring that is in progress. (CODECONVENTIONS
already specify proper syntax for both arguments and xrefs, based
on CPython conventions).
This adds description of implied AbstractNIC base class, which should be
"subclasses" and implemented by a particular network device class.
This is just an initial step in that direction, the API and description
will be elabotated further.
The list starts with the simplest functionality - GPIO, proceeds to
communication interfaces (UART, SPI, I2C), the to time(r) related
things, then everything else.
For a couple of ports, there was information which directory is set
as current after boot. This information doesn't belong to "uos" module,
and is moved to boards' references (which actually already contained
information on which directory is chosen for boot, even if without
explicit mentioning that it becomes current directory, which is now
done).
This method isn't implemented in any port. It seemed to have originated
in cc3200 port, but actually never was implemented there either. In
general case, it's impossible to implement this method (for example, for
a perfect GPO, which has only output latch without any feedback look
into a CPU).
Both aren't part of generic Hardware API: It's impossible to implement
.id() method in a generic case (e.g., when Pin is instantiated by the
underlying OS/RTOS). .board attribute is an obvious space hog which
instead can be implemented on Python level if needed.
MONO_xxx is much easier to read if you're not familiar with the code.
MVLSB is deprecated but kept for backwards compatibility, for the time
being.
This patch also updates the associated docs and tests.
* Fix mis-spelling of `ticks_add` in code examples.
* Be consistent about parentheses after function names.
* Be consistent about formatting of function, variable and constant names.
* Be consistent about spaces and punctuation.
* Fix some language errors (missing or wrong words, wrong word order).
* Keep line length under 90 chars.

User can override PYTHON executable before running script,
gen-cpydiff.py works only with Python3 and most systems register
its executable as 'python3'.
This patch introduces the a small framework to track differences between
uPy and CPython. The framework consists of:
- A set of "tests" which test for an individual feature that differs between
uPy and CPy. Each test is like a normal uPy test in the test suite, but
has a special comment at the start with some meta-data: a category (eg
syntax, core language), a human-readable description of the difference, a
cause, and a workaround. Following the meta-data there is a short code
snippet which demonstrates the difference. See tests/cpydiff directory
for the initial set of tests.
- A program (this patch) which runs all the tests (on uPy and CPy) and
generates nicely-formated .rst documenting the differences.
- Integration into the docs build so that everything is automatic, and the
differences appear in a way that is easy for users to read/reference (see
latter commits).
The idea with using this new framework is:
- When a new difference is found it's easy to write a short test for it,
along with a description, and add it to the existing ones. It's also easy
for contributors to submit tests for differences they find.
- When something is no longer different the tool will give an error and
difference can be removed (or promoted to a proper feature test).
MicroPython guarantees '/' to be a path separator, so extra constant taking
precious ROM space are not needed. MicroPython never had such constant, only
one vendor port had it (now unmaintained).
This new function controls what happens on a hard-fault:
- debugging disabled: board will do a reset
- debugging enabled: board will print registers and stack and flash LEDs
The default is disabled, ie to do a reset. This is different to previous
behaviour which flashed the LEDs and waited indefinitely.
machine.time_pulse_us() is intended to provide very fine timing, including
while working with signal bursts, where each transition is tracked in row.
Throwing and handling an exception may take too much time and "signal loss".
So instead, in case of a timeout, just return negative value. Cases of
timeout while waiting for initial signal stabilization, and during actual
timing, are recognized.
The documentation is updated accordingly, and rewritten somewhat to clarify
the function behavior.
