* make sure that gamma LUT is always initialized
* remove some unnecessary safety checks
* make gamma8() inline, for more speed
* use fast unGamma8 for preview
* add super-fast unGamma8 for HUB75 - old function lost 3-10 fps, this version does not reduce fps at all *grins*
Enable building color correction code if you really need it.
The effect of color correction is less noticeable on HUB75 than on ws2812b, however it can reduce your framerate by up to 10%.
previously gPC cached busses were disabled in slowMode (one pixel mapped to several outputs). However this should not be needed, because the first copy found should be like all other.
* optimize loops that scan through all busses
* small speedups for Bus::autoWhiteCalc()
* small speedups for ColorOrderMap::getPixelColorOrder()
thanks to github Copilot for giving me the right ideas for this optimization
This disables bus caching (and related speedups) while receiving realtime UDP pixels.
Its still totally unclear to me what happens, and why disabling the cache solves problems.
* BusManager::show(): explicitly wait until the bus driver is idle (done by NPB show, too, but in a different way)
* BusManager::removeAll(): use delay() instead of yield() - yield() does _not_ free the processor on esp32!
It seems that the FM6124 driver makes some "outdoor" panels work, that previously only showed random color flicker. FM6124 is largely compatible with panels that did work with the standard driver, too.
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
very minor changes:
* HUB75 bus don't leave _len uninitialized, handle display == nullptr before using display members
* __attribute__((pure)) was in the wrong location
* wled00.ino: made lps (loops-per-second) calculation a bit more accurate
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)
