Art-Net Improvements
* AsyncUDP instead of WiFiUDP so it's much faster
* Support for professional Art-Net gear with many outputs
* Color-order remapping
* ESP32-P4 SIMD assembly optimization for brightness calc, a bit faster
* Full GUI support for all settings
* GUI guidance for setup
similar to getPixelColor, but returns the original pixel without brightness adjustments.
* getPixelColorRestored is used by segment::sPC and segment::gPC
* getPixelColor is still used by ABL (auto brightness limiter)
the HUB75 driver seems to randomly produce glitches, especially on hight contrast edges.
* roll back to HUB75 version 3.0.10 (known good)
* limit max brightness to 238 (=92%)
* add short delay after starting the driver
* code cleanup, removing some unneeded sanity checks
* use dirty bits in double buffer mode, too -> only not-black pixels are drawn into the back-buffer (20%-30% faster)
Instead of using the memory-hungry driver double buffer, this implements a LEDS buffer inside the BusHub75Matrix class.
--> up to 50% faster
--> uses one "dirty" bit per pixel, to only re-transmit pixels that changed after the last "show"
* move HUB75 implementation into bus_manager.cpp
* add "override" keyword
* include FastLED.h if not included previously
* move RGB macros into bus_manager.h
adding hints for the compiler for optimization.
In case your custom build complains about "const", just remove the keyword. based on e82f38e277, but going further :-)
* "const" class functions : function does not modify any class attributes ( --> "this" becomes const)
* __attribute__((pure)) : function return value depends only on the parameters and/or global variables. The function does not modify any global or static variables.
* __attribute__((const)) : function only examines arguments (no globals), and has no effects except the return value. This slightly more strict than "pure"
* hot: tells the compiler "this functions is called very often"
* cold: the opposite of hot
* adding an optional parameter to setBrightness(). ApplyPostAdjustments() will only be called if `immediate=true`. Only ABL will use immediate=true, to ensure electrical safety of equipment.
This allows some optimizations of performance, as ApplyPostAdjustments() is time consuming.
* busses.setBrightness(bri) --> applied to all future pixels (fast, lossless)
* busses.setBrightness(bri, true) --> applied directly to all previously set pixels (slower, lossy)
* getpixelcolor: attribute pure - it reads memory, but does not write
* some optimizations for SEGMENT.blur() and SEGMENT.fadeToBlackBy()
* FX.c:pp remove double calls to blur() and fade_out()
* FX.cpp: SEGMENT.setUpLeds() added to effects, to enable LED buffering (safe some time because getPixelColor does not need to access NeopixelBus)
* a few other optimizations to safe time and avoid "expensive" operations
* set I2C bus speed to 400kHz (default is 100Khz)
* a few other small optimizations and tweaks
* pio: esp32 V4 builds use "patch5" toolchain version, which contains a few bugfixes especially for memory management.
* make local functions "static"
* use fast_ int types where possible
* use native min/max instead of MIN/MAX macros. Macros evaluate each parameter TWICE!!
* adding __attribute__((pure)) and __attribute((const)) to help the compiler optimize
* ws.cpp: reduce max "live leds" in fastpath mode
* Support white addressable LED strips
* Various white handling tweaks
Allow RGB controls for white-only busses depending on AWM (makes palette-only FX work on non-RGB addressable busses)
Fixed RGB controls hidden if segment contained any non-RGB bus (even though there is also an RGB bus in that segment)
New Max auto white mode
Added hasCCT() bus method
Rename methods to be clearer
WS2811 White getPixelColor fix()
* Fix merge conflict (bus manager cpp)
* Refactor bus manager.
* Fix for net debug
* Fix 8266 compile
* Move bus static members to proper cpp
