* Rebaseline firmware to non-OS SDK version 3.0
* Note that SDK version 3.0 introduces the concept of a Flash Partition Table(PT). This is located at Flash offset 0x10000 in our firmware build.
* The firmware is now PT aware with both LFS and SPIFFS taking their partition size and location from the PT
* A new tool `tools/nodemcu-partition.py` is now used to initialise these data and can also download LFS and SPIFFS images to these partitions.
* I2C driver speed-up, i2c.SLOW, i2c.FAST and user-defined speed selection
* - Multiple buses (up to 10) with different speeds on each bus
- Standard(Slow, 100kHz), Fast(400kHz) and FastPlus(1MHz) modes or an
arbitrary clock speed
- Sharing SDA line over multiple I²C buses to save available pins
- GPIO16 pin can be used as SCL pin, but it does not support clock
stretching and selected bus will be limited to FAST speed.
* Dynamic memory allocation, error checks, simplification, timing tweaks.
* Separated the code of old driver for better compatibility and simplicity
* Change of driver interface
* Add bus status check in setup(); simplify getDC(); remove unnesessary lines in ACK read/write
* Fix for moved doc file and trailing whitespaces
* DHT11 read sometimes failed with checksum error.
The code assumed DHT11 devices only ever return zero in the temperature and humidity decimal fraction bytes. The datasheet doesn't guarantee this is the case, and by observation I have noticed that indeed the DHT11 may sometimes return another number, usually close to zero. This means that the code would fail with a checksum error, as the fraction bytes were not included when the checksum was calculated. These bytes are now taken into account and also returned as part of the measurement.
This also means that the related dht.read() function is non-functional. If you have a DHT11 device that returns a non-zero decimal part, dht.read() will interpret it as a DHT22 result and return the wrong measurement. For this reason dht.read() should be retired. This patch does not address this issue.
* lua_modules/fifo: a generic queue & socket wrapper
One occasionally wants a generic fifo, so here's a plausible
implementation that's reasonably flexible in its usage.
One possible consumer of this is a variant of TerryE's two-level fifo
trick currently in the telnetd example. Factor that out to fifosock for
more general use.
* lua_examples/telnet: use factored out fifosock
* lua_modules/http: improve implementation
Switch to fifosock for in-order sending and waiting for everything to be
sent before closing.
Fix header callback by moving the invocation of the handler higher
* fifosock: optimistically cork and delay tx
If we just pushed a little bit of data into a fifosock that had idled,
wait a tick (1 ms) before transmitting. Hopefully, this means that
we let the rest of the system push more data in before we send the first
packet. But in a high-throughput situation, where we are streaming data
without idling the fifo, there won't be any additional delay and we'll
coalesce during operation as usual.
The fifosocktest mocks up enough of tmr for this to run, but assumes
an arbitrarily slow processor. ;)
A block of memory is accessed after having been freed. This was obscured by the fact that 'oBuf' is a pointer into the middle of the block 'dynamicTables', so when dynamicTables is freed, oBuf is pointing to freed memory. Occasionally, luac.cross would crash because of this.
Files changed only by the author of FatFS (only updated to new version):
- 00history.txt
- 00readme.txt
- ff.c
- ff.h
- ffunicode.c
- diskio.h
- integer.h
- files in `option` folder except `syscall.c`
Changes:
- removed option folder (now everything is in ffunicode.c)
- modified Makefile to support new version of FatFS
- removed syscall.c and modified ffsystem.c from FatFS author instead
- modified files: diskio.c, ffconf.h to mimic changes from new version
- modified files: fatfs_config.h, myfatfs.c
because of changes of configuration keywords in 0.13 version
- removed empty lines from beginning of files:
fatfs_prefix_lib.h, myfatfs.c, sdcard.c
- changed version number in documentation
* Update TLS protocol support
TLS1.0 is past PCI's EOL; BEAST is no more
Enable elliptic curve key exchanges
Do not enable the smallest ECs for security
Do not enable the largest ECs for computational time
Do not enable 25519 (sad) because it doesn't go across the wire
Drop non-PFS key exchanges
Drop ARC4, Blowfish, DES, genprime, XTEA code
Drop renegotiation support completely
It takes so much heap that it's not likely to work out well
Tidy handling of SSL_BUFFER_SIZE
Update docs
Drop mention of startcom, since they are no more, for letsencrypt
* Update mbedtls to 2.7.7
Preserve our vsnprintf and platform hacks
* Introduce TLS maximum fragment size knob
Reduce buffer size to 4Ki by default and advertize that. That's the
largest we can advertize with the TLS MFL extension, so there's no
point in making them larger. The truly adventurous can re-raise
SSL_BUFFER_SIZE and undefine the SSL_MAX_FRAGMENT_LENGTH_CODE and get
back to the earlier behavior.
* Default to mbedTLS debug with DEVELOP_VERSION
* Add spi.set_clock_div
This will allow the SPI clock divider to be changed relatively simply,
to better support multiple devices with varying SPI clock rate support
* Add documentation
* Download pre-built toolchains
* Updated to include the platform in the name of the pre-built toolchain
* Download archive into cache/
* Update Travis configuration to use pre-built toolchain via make
* MQTT: handle large/chunked/fragmented messages properly
If a message spans multiple TCP packets it must be buffered before
delivered to LUA. Prior code did not do this at all, so this "patch"
really adds proper handling of fragmented MQTT packets.
This could also occur if multiple small messages was sent in a
single TCP packet, and the last message did not completely fit in that
packet.
Introduces a new option to the mqtt.Client constructor:
max_publish_length which defaults to 1024
Introduces a new 'overflow' callback.
Fixes issue #2308 and proper fix for PR #2544.
* mqtt.md: clarified heap allocation
* mqtt: ensure ack is sent for overflowed publish
If QoS is used we should still acknowledge that we received it, or server might retransmit it later.
