Fixes#6066
Preserve any existing sample rate for the I2S unit when performing an
`i2s_begin`. If nothing has ever been set, default to 44.1KHz as
before.
* Add a FS::check() optional method
Fixes#2634
Expose any low-level filesystem check operations for users, and add
documentation on this and the gc() methods.
* Update doc w/more gc() info and link
* Update LittleFS to current project head
Several bugfixes noted in the LittleFS added:
https://github.com/ARMmbed/littlefs/commits/master
* Also update SdFat to latest upstream head
Also adds a delay(0) every 5000 fat clusters examined to avoid WDT
errors on highly fragmented FAT filesystems.
Fixes#5116Fixes#2743
The Arduino WiFiClient object allows sending the same packet to all
connected clients of a WiFiServer. In their implementation it may make
sense, but on the 8266 with things like SSL it doesn't.
Update the docs to note that WiFiServer::write() is a no-op, and that
the app should use the WiFiCliebnt::write() on all connected clients as
appropriate.
Fixes#2567
Allow the web server to send plain C strings instead of requring they be
encapsulated inside a String class object. Saves memory vs. having to
convert C strings to Strings (i.e. duplication of data), overloads on
the efficient sendContent_P(char*) methods.
Looking at other projects, they're all building using gnu extensions
(-std=gnu++11). We're already embedding gnu-specific pragmas for
compile options, so I see no reason not to fall in line w/others on
this.
Fixes#4639
Default mode (no exceptions) will no longer use the stdc++ library new
allocator when there is not enough memory. Instead, it will return
nullptr. This is the pre-exceptions-available behavior (2.5.0 and
earlier).
When exceptions are enabled, use the real new and throw exceptions that
can be caught at higher levels, or which will crash the app with an
uncaught exception if they're not handled.
Update to #6309
Fixes#2090
The Updater checks that an update isn't already in progress on ::begin,
but when an error happens in the middle of an upload it's impossible to
actually reset this flag w/o a reboot.
Reset the state members (esp. _size) on any error condition so
that you can restart the transfer with a new ::begin. Any error
condition is fatal, anyway, so there is no reason not to clear the
current state at that point.
The SPIFFS config object was defined in FS.h in its own namespace, but
is not made easily available like other SPIFFS and FS objects because of
a missing `using` statement. Add it in FS.h
Fixes#6322
* Upgrade to 2.5.0-4 toolchain w/improved pgm_read_x
Rebuild the entire toolchain (including standard libraries) with the
latest pgm_read_xxx headers included (which fix unaligned dword reads
from progmem and run faster/smaller, and a pgm_read_byte change which
removes an instruction on each read saving flash).
Pull in latest bearssl while we're at it, too, which speeds up EC
handshakes and reduced ROM usage, too.
* Fix C++ exceptions
Exception code now only does 32b aligned reads from progmem to access
the eh_table (some via -mforce-l32, some via hand-inserted pgm_read_x
macros).
Fixes#6151Fixes#6305Fixes#6198
Fixes#6068
Drop from the tools key all version:"1.20.0-26-gb404fb9" entries (which
were pre-2.0.0 and whose entry in platform versions was deleted on last
release).
* workaround when an exceptin occurs while in an ISR
* tuning for gdb
* remove dead code and rename defines/variables
* per reviews: naming, handle "unhandled return" case
* fix reset message
* Created empty method
* Changed method name from "empty" to "isEmpty". Created a new method to empty a string
* Changed method name from "empty" to "clear".
Cleans up all warnings seen w/GCC 9.1 to allow it to track the main
branch more easily until 3.x.
Does not include Ticker.h "fix" of pragmas around a function cast we're
doing that GCC9 doesn't like, that will be addressed separately and
maybe only in the 3.0 branch.
Does not include GDB hook fix, either, because the pragmas required
to disable the GCC9.1 warnings don't exist in 4.8 at all.
* Add a dump of received FP and CERT when in debug mode
To simplify BearSSL debugging, print the received FP (when it doesn't
match the expected) and the binary certificate (always), when in debug
mode.
* Add documentation section on FP mismatch in rare instances.
Without this the compiler may use memory references loaded to registers before the fence, in computation within the fence. These values could have changed before xt_rsil()
(critical section start) was called.
Note: this is needed to stop the compiler from reordering instructions at the critical section boundary.
* Prepare signing before sketch is compiled
This makes the right value available in ARDUINO_SIGNING in the sketch.
* Remove unnecessary .1s and fix packager script
- Add HelloEspnow.ino example to demonstrate the ESP-NOW mesh backend features.
- Deprecate the ESP8266WiFiMesh class in favour of the new ESP-NOW and TCP/IP backends.
- Update the TCP/IP mesh backend to use the new lwIP version preprocessor flag and remove obsolete preprocessor flags.
* enable by default latest 2.2.x firmware, including fixed espnow
* LittleFS: avoid crash when FS size is 0
* flash size defaults: 1M for generic board, not empty FS for all
* Make SPIFFS be an integer number of blocks
boards.txt.py simply calculated the end and start using flash sizes, but
in cases where an 8K page was used (>512KB SPIFFS), this could leave a
4K half-block left at the end of SPIFFS.
mkspiffs and the SPIFFS code uses integer division to calculate the
maximum block number, so it worked fine in practice and the code simply
ignored the extra, fractional block.
Now actually take block size into account when calculating the end of
SPIFFS, ensuring no fractional blocks are passed in. Does not result in
data loss on pre-existing SPIFFS filesystems.
* Fix the 1m512 case and clean up code
Ensure that no SPIFFS_block in the LD files is modified from the
original to endure correct backwards compatibility
* Factor out common if, clean code
* Make boards.py vars "fs_xx" instead of "spiffs_xx"
* Add support for newer mobile OS changes.
Took me quite a while to figure this out, but according to this issue (https://github.com/espressif/arduino-esp32/issues/1037), in order to get a captive notification to show or the popup to open, the DNS server must resolve to a public IP. It will not work with a pivate one (e.g. 192.168.4.1).
On Android, a notification ("Register with Network") is displayed in top left notification bar.
On IOS, the login popup is displayed.

Apply most compatible changes needed to get the core compiling under GCC
7.2 to the main gcc 4.8 tree to ease porting for 3.0.0.
Update pgmspace.h with corrected and optimized unaligned pgm_read
macros. Now pgm_read_dword in the unaligned case gives proper results
even if optimization is enabled and is also written in assembly and only
1 instruction longer than the pgm_read_byte macro (which also has been
optimized to reduce 1 instruction). These changes should marginally
shrink code and speed up flash reads accordingly.
The toolchain should/will be rebuilt at a later time with this
optimization to ensure it's used in the libc.a/etc. files.
After verifying that they really were spurious, clean up the warnings
that gcc -wextra reports, except for LeaMDNS.
Upgrade GCC to gcc-7 for host builds
