1708fe3cc7 esp8266/modmachine: Add WDT_RESET and SOFT_RESET constants. 
Both tested to work. (WDT_RESET can be seen by issuing machine.disable_irq()
and waiting for WDT reset, SOFT_RESET - by machine.reset()).

9c04ef2a67 unix,stmhal,esp8266: When find'ing frozen files don't use extra slash. 
This extra forward slash for the starting-point directory is unnecessary
and leads to additional slashes on Max OS X which mean that the frozen
files cannot be imported.

Fixes #2374.

59a9509703 esp8266/modules/ds18x20.py: Add support for DS18S20 devices. 2016-08-29 12:45:07 +10:00
Damien George
8e9b98e974 esp8266/modules/onewire: Change onewire.read() to onewire.readinto(). 
This allows 1-wire drivers (eg DS18X20) to perform in-place operations and
hence do less memory allocations.

9fba618356 esp8266/modules: Split onewire.py into OneWire and DS18X20 driver. 
The OneWire class is now in its own onewire.py module, and the temperature
sensor class is in its own ds18x20.py module.  The latter is renamed to
DS18X20 to reflect the fact that it will support both the "S" and "B"
variants of the device.

These files are moved to the modules/ subdirectory to take advantage of
frozen bytecode.

d29ca28288 esp8266/modous: Add os.umount method to unmount a filesystem. 
This is an object-oriented approach, where uos is only a proxy for the
methods on the vfs object.  Some internals had to be exposed (the STATIC
keyword removed) for this to work.

Fixes #2338.

891479e62a esp8266/hspi: Enable duplex operation of hardware SPI 
Without this, spi.read(1, 0xff) would use 16 clock cycles,
first to send 0xff and then to receive one byte, as visible
with a logic analyzer.

8e7dfea803 esp8266/modpybhspi: Add a HSPI module for hardware SPI support 
This module uses ESP8266's SPI hardware, which allows much higher
speeds. It uses a library from

675d1c9c60 ports: Remove typedef of machine_ptr_t, it's no longer needed. 
This type was used only for the typedef of mp_obj_t, which is now defined
by the object representation.  So we can now remove this unused typedef,
to simplify the mpconfigport.h file.

3372f69586 esp8266/esp8266.ld: Increase firmware image size to 0x90000 (576K). 
Of them, 0x87000 is irom0 segment.

This is required to ship increasing number of modules and examples
developed in teh course of ESP8266 port project.

6de37864a2 esp8266/scripts/inisetup: Add commented-out call to esp.osdebug(None). 
That apparently will only help folks who read the docs on how to disable,
but could use a quick reminder straight in boot.py. For the developers,
it's important to have debug logging enabled in development branch
(master).

e33d2383d1 esp8266/modesp: Add check_fw() function to check integrity of the firmware. 
Requires firmware generated by the latest makeimg.py (which stores size
and md5 of the firmware together with the firmware itself).

bf47b71b78 esp8266/makeimg.py: Append md5 hash to the generated binary.

auto-config.

64ad838fde esp8266/esp_mphal: Implement libc's errno. 
Using __errno() function, and redirect it to use mp_stream_errno from
stream module. This is pre-requisite for integrating with 3rd-party libs,
like BerkeleyDB.

61e77a4e88 py/mpconfig.h: Add MICROPY_STREAMS_POSIX_API setting. 
To filter out even prototypes of mp_stream_posix_*() functions, which
require POSIX types like ssize_t & off_t, which may be not available in
some ports.

ba2c503541 esp8266/mpconfigport.h: Include sys/types.h for POSIX types definitions.

aa4ada943a esp8266/modpybuart: Fix UART parity setting. 
The configuration bits for the UART register were wrong and the parity
couldn't be enabled, because the exist_parity member hasn't been updated. I
took this ESP8266 register description (http://esp8266.ru/esp8266-uart-reg/)
as reference.

Verification has been done with a logic analyzer.

0d221775f5 esp8266/_boot.py: Decrease GC alloc threshold to quarter of heap size. 
The idea behind decrease is: bytecode and other static data is also kept on
heap, and can easily become half of heap, then setting threshold to half of
heap will have null effect - GC will happen on complete heap exhaustion like
before. But exactly in such config maintaining heap defragmented is very
important, so lower threshold to accommodate that.

c141584e1e esp8266/_boot.py: Set GC alloc threshold to half of heap size. 
Should keep good chunk of heap unfragmented, if a user application allows
that at all.
