* 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.
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
* 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.
The volume returned by file.mount() could not be unmounted, because vol:umount() would fail with a cryptic error about the uncallable nature of the volume userdata object. This was due to the wrong metatable name being used for setting up the volume structure. The correct name, as registered elsewhere in file.c, is now used, and vol:umount() is callable.
Any TCP packet with more than 1024 bytes of payload was silently
dropped. With MTU of 1500 the TCP payload can be up to 1460 bytes
(1500 - 20(IP hdr) - 20(TCP hdr))
- Optimise ROTable accesses and interface
This includes some refinements to the ROTable cache which remove the linker cludges on the CROSS_COMPILE builds. Also keyhole tweaks to some of the Lua VM code to implrove runtimes.
I also noticed some compile time warnings during the build; the change to uz_unzip.c doesn't impact the compiled code, but does remove the compiler warnings.
Use separate names for the integer and float `luac.cross` binaries. Also adds local/lua directory which is already supported by tools makefile to build LFS image.
* updated wifi_eventmon to store events in LUA_REGISTRYINDEX
* updated wifi_eventmon debug comments
* Updated wifi.c to remove c_free()
In wifi_ap_listclient(app/modules/wifi.c), c_free() was replaced with
wifi_softap_free_station_info()
* Removed unnecessary line of code from app/modules/wifi_eventmon.c
* fix application of patch 0018-feat-espconn-Modification-for-espconn.patch in #2269
espconn_tcp_reconnect() was removed instead of espconn_list_delete()
* pmsleep refactor
* Shortened swtmr disabled message
* Added swtimer debug module option to user_modules.h.
* Added comments to user_config.h.
* Fixed error in documentation for node.sleep()
* remove blank sntp.c that got added in during rebase onto dev(6218b92)
* Added #ifdefs around SWTIMER_REG_CB to prevent inclusion of disabled
code
Added `node.egc.meminfo()` to expose LVM usage (to make the regular
`node.egc.ON_MEM_LIMIT` option usable).
Extended the `node.egc.ON_MEM_LIMIT` option to also take negative limits,
in which case that's taken as a request to keep a certain amount of heap
available for non-Lua use.
ds18b20 decimals do not take into account the sign bit. Since the original calculation was not so readable, rewritten in readable way that also fixes the bug. Same code as PR against master.

Apply local changes to build:
app/include/lwip/app/espconn.h pulls changes (and license decl) from
upstream SDK. Makefile is altered to use this file ahead of the
SDK's.
Remove lwip's sntp support, since it was never really wired in anyway.
See https://github.com/nodemcu/nodemcu-firmware/issues/2042 for more
information. Patch Makefile to strip time.o, the consumer of lwip's
sntp functionality, from libmain.a, resulting in much
easier-to-understand error messages.
This has consequences for mbedtls. The simplest thing to do, which is,
impressively, not a change in behavior, is to completely disable TLS
certificate time validation; a later patch can optionally couple this to
RTCTIME support.
Similarly, it happens that the sqlite3 import was calling time(), but
this was not going to work out well for it. Just stub it out to always
return unix timestamp 0, as would have happened anyway.
Changes unprocessed:
0007-sync-from-080c37e1.patch
0008-feat-lib-Compile-some-libraries-with-ffunction-secti.patch
These two make changes to the linker script; perhaps
they are worth porting over, but I have not done so
here.
This is build-tested (ADC, BIT, COLOR_UTILS, CRON, CRYPTO, DHT, ENCODER,
FILE, GPIO, HTTP, I2C, MQTT, NET, NODE, OW, PCM, PERF, PWM, RTCFIFO,
RTCMEM, RTCTIME, SNTP, SPI, SQLITE3, STRUCT, TLS, TMR, UART, WIFI,
WS2812, WS2812_EFFECTS) and boots, but only limited run-time testing has
been performed. Testing done does, however, include having made a few
TLS connections through the HTTP module, so things are not hopelessly
broken, at the very least.
