Its addition was due to an early exploration on how to add CPython-like
stream interface. It's clear that it's not needed and just takes up
bytes in all ports.

The ESP SDK supports configuring the hostname that is
reported when doing a DHCP request in station mode. This commit
exposes that under network.WLAN(network.STA_IF).config('dhcp_hostname')
as a read/write value similar to other parameters.

Now, to use frozen bytecode all a port needs to do is define
FROZEN_MPY_DIR to the directory containing the .py files to freeze, and
define MICROPY_MODULE_FROZEN_MPY and MICROPY_QSTR_EXTRA_POOL.

Previously, it was included only in release builds, but it's important
tool which should be always at the fingertips to be useful (and to
pump up its usage).

At the WS2812 driver level, a 400ns value was used for T0H (time high to
send a 0 bit) but LED specification says it should be 350ns +- 150ns.
Due to loop overhead the 400ns value could lead to T0H close to 500ns
which is too close from the limit value and gave glitches (bad data to
pixels) in some cases. This patch makes the calculated T0H value 350ns.

Previously they used historical "pyb" affix causing confusion and
inconsistency (there's no "pyb" module in modern ports; but people
took esp8266 port as an example, and "pyb" naming kept proliferating,
while other people complained that source structure is not clear).

Following best-practice use of the const feature, to make it compatible
with Python.

Size 64 was incorrect and will lead to stack corruption. Size 88 was
verified empirically. Also, allow to skip defining it if MD5_CTX
preprocessor macro is already defined (to avoid header conflict).

ESP8266 SDK2.0 fixes (at least, I can't reproduce it) an infamous bug
with crash during scan. 36K seams to be a safe value based on a download
test (test_dl.py), over 1GB was downloaded. More testing is needed, but
let's have other people participate by committing it now.

There is no automatic reconnect after wlan.active(False);
wlan.active(True). This commit provide the possibility to run
wlan.connect() without parameter, to reconnect to the previously
connected AP.

The NeoPixel class now handles 4 bytes-per-pixel LEDs (extra byte is
intensity) and arbitrary byte ordering. APA102 class is now derived from
NeoPixel to reduce code size and support fill() operation.

To build, "make 512k".
Disabled are FatFs support (no space for filesystem), Python functionality
related to files, btree module, and recently enabled features. With all
this, there's only one free FlashROM page.

As we're looking towards adding OTA support, calculation of a FlashROM
area which can be used for filesystem (etc.) may become complex, so
introduce C function for that. So far it just hardcodes current value,
0x90000. In the future the function may be extended (and renamed) to
return the size of area too.

In order to have more fine-grained control over how builtin functions are
constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific,
with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW. These names now
match the MP_DEFINE_CONST_FUN_OBJ macros.

Now frozen modules generation handled fully by py.mk and available for reuse
by any port.

Concurrent WebREPL connections were never supported, now actually check
for this.

It's probably not strictly needed so far, but serves as an example of
MP_FASTCODE use and may be helpful in the future.
|

It can be used in the following manner:
void MP_FASTCODE(foo)(int arg) { ... }

SDK 2.0.0 goes into boot loop if a firmware is programmed over erased flash,
causing problems with user experience. This change implements behavior
similar to older SDKs': if clean flash is detected, default system
parameters are used.

As long as a port implement mp_hal_sleep_ms(), mp_hal_ticks_ms(), etc.
functions, it can just use standard implementations of utime.sleel_ms(),
utime.ticks_ms(), etc. Python-level functions.

Added options to make deploy so it can be used for ESP8266 boards with
other flash configurations. For example NodeMCU DEVKIT V1.0 can now use:
$ make FLASH_MODE=dio FLASH_SIZE=32m deploy

upip will use first non-empty component in sys.path as an install path
(if MICROPYPATH envvar is not set, like it will be for baremetal targets).

in different cases.

The delay_half parameter must be specified by the port to set up the
timing of the software SPI. This allows the port to adjust the timing
value to better suit its timing characteristics, as well as provide a
more accurate printing of the baudrate.
