Enable the new concurrent request and queue size limit features
of AsyncWebServer. This should improve the handling of burst
traffic or many clients, and significantly reduce the likelihood
of OOM crashes due to HTTP requests.
* added bitwise operation based sqrt16
- replacement for fastled, it is about 10% slower for numbers smaller 128 but faster for larger numbers. speed difference is irrelevant to WLED but it saves some flash.
* updated to 32bit, improved for typical WLED use
- making it 32bits allows for larger numbers
- added another initial condition check for medium sized numbers
- increased the "small number" optimization to larger numbers: the function is currently only used to calculate sqrt(x^2+y^2) which even for small segments is larger than the initially used 64, so optimizing for 1024 makes more sense, although the value is arbitrarily chosen
- Implement vector in bus manager
- Memory calculation according to explanation from @Makuna
- Prefer 8 RMT before 8 I2S on ESP32 (fixes#4380)
- speed improvements in ABL
- verbose debugging
- get bus size from NPB (prototype)
- Parallel I2S output bugfix
- automatic selection of appropriate I2S bus (`X1xxxxxxMethod`)
- removed I2S0 on ESP32 (used by AudioReactive)
- renumbered internal bus numbers (iType)
- added buffer size reporting
* removed unneeded initializations in blur() and blur2D()
* remove check for _t in progress()
* code readability: if (_t) --> if(isInTransition())
* add `isInTransition()` checks to currentBri() and currentMode()
* added missing `_transitionprogress = 0xFFFFU` in stopTransition()
This is purely a "clean code" thing, no impact on function - it helps to avoid confusion when reading the code.
C++ allows declaration and implementation to use different variable names.
* changed some parameters to "pointer to const", so compiler can better optimize code size and performance - because data behind a const pointer will never be modified by the called function.
* made setPixelColor `const`
* fixed a few potentially uninitialized local vars (the may have random values if not initialized)
* avoid shadowing "state" in handleSerial()
* plus a few very minor improvements
* make XY() and _setPixelColorXY_raw() const (minor speedup)
* segment is a struct not a class: friend class Segment --> friend struct Segment
* fix missing braces around two macros
* use non-throwing "new" where possible
* improve robustness of transition code
