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.
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.
A previous version of the 1-wire driver (which was recently replaced by the
current one) had this behaviour and it allows to create a 1-wire bus
without any external pull-up resistors.
And and FLASH_FS, and use "K" values instead of hex numbers for lengths.
The increase of FLASH_TEXT is to allow more frozen bytecode for a
particular user's project. It's not used for anything else.
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).
The idea is that these tests can be run with just a test server running
on a test host, with device under test connecting to it, instead of
requiring Internet connection for testing.
Such setup is however WIP, and some tests in net_hosted/ are so far
written to connect to Internet, as there're not test server written
yet. This is expected to evolve over time.
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).
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).
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.
