Before your options were to have vertical strips. * Now you can use a corkscrew mapping [fl/corkscrew.h](src/fl/corkscrew.h), see [examples/FestivalStick](examples/FestivalStick/) * You input the number of LEDS + number of turns. * Corkscrew will provide a surface XY grid that you draw too. * then call Corkscrew::draw(), and the current surface will be mapped to the corkscrew. * Rendering is done via 2x2 bilinear sampling. Looks great! * Animartrix - 30% faster due to forced `-O3` and `fastmath` compiler settings for this one file. * Ease Functions - lots and lots of ease functions! Great for animations! * see [fl/ease.h](src/fl/ease.h) and the demo [examples/Ease/Ease.ino](examples/Ease/Ease.ino) * Fast! Everything is done in integer space. * 3D Perlin noise (`inoise8(x, y, z)`) range utilization improved from 72.9% to 88.6% * Significantly better quality for volumetric LED effects (3D fire, clouds, particles) * Uses industry-standard 12 edge vectors of a cube for optimal gradient coverage * **Adafruit NeoPixel Bridge**: Optional Adafruit_NeoPixel clockless controller support * For some platforms Adafruits NeoPixel just works better. * Enable with `#define FASTLED_USE_ADAFRUIT_NEOPIXEL` before including FastLED * Now your WS2812 chipset will use the AdafruitNeopixel library (if installed) * New LED chipset: SM16824E * 3-Wire * See also: https://github.com/FastLED/FastLED/issues/1941#issuecomment-2981643952 * apollo3_red (stm variant): beta support. * HSV16 support * CRGB -> HSV -> CRGB is highly lossy * CRGB -> HSV16 -> CRGB is almost perfect. * Integer based so it's fast. * ColorBoost * CRGB::colorBoost() * Are you doing video on WS2812? Well then you probably are using gamma correction * Color Boost is an alternative for gamma correction for the WS2812 and other RGB8 chipsets. * It preserves luminosity but allows you to increase saturation. * HSV16 is used to preserve color resolution. * HSV -> CRGB default conversion function can now be overriden. * Thanks to https://github.com/ssilverman or this full spectrum HSV implementation. * If you just want to change it for your sketch you can use this: * `#define FASTLED_HSV_CONVERSION_RAINBOW` (default) * `#define FASTLED_HSV_CONVERSION_SPECTRUM` * `#define FASTLED_HSV_CONVERSION_FULL_SPECTRUM` * To change for the entire engine (recommended) then set these as build flags: * `-DFASTLED_HSV_CONVERSION_RAINBOW` * `-DFASTLED_HSV_CONVERSION_SPECTRUM` * `-FASTLED_HSV_CONVERSION_FULL_SPECTRUM` * [fl/fetch.h](src/fl/fetch.h) * A non blocking http fetch library returning an [fl/promise.h](src/fl/promise.h) * You can then await the promise with `fl::await` or install a callback to be invoked. The latter is recommended. * [fl/json.h](src/fl/json.h) rewrite * Much more ergonic library. Fast parsing for packed arrays of number * The underlying ArduinoJson library is only ergonomic if you allow `std:string` and `std::sstream`, which is missing on platforms like avr. So we had to write our own api to handle this. * Platforms * ESP32-C5 is now supported. * ESP32 WS2812 SPI driver has a fix for it's async draw routine. * Blend2d will now replace a subfx XYMap (when necessary) to prevent double mapping. A warning will be issued. * Seeed XIAO nRF52840 Sense: Fixed incorrect pin mappings that were copied from Adafruit Feather board * **APA102HD Gamma Correction Algorithm**: Completely rewritten with closed-form mathematical solution * Thanks https://github.com/gwgill! * Graph of the old algorithms quantization issues can be see here: * https://www.argyllcms.com/APA102_loglog.svg * STM32F1 pin mapping fixes (blue pill) * https://github.com/FastLED/FastLED/pull/1973 * Thanks https://github.com/vishwamartur! * Internal stuff * FastLED is now way more strict in it's compiler settings. Warnings are treated as errors * Lots of fixes, some code required amnesty. * The examples now compile under clang and run for `./test` * All examples now compile for ALL platforms. * this was a major undertaking. * required a rewrite of the testing infrastructure. * Teensy41 took ~ 1 hours to compile 40 examples, now it can do 80 examples in ~8 mins **Color Boost Demo** ![image (3)](https://github.com/user-attachments/assets/d478a94a-d507-4dfd-a9bf-ffe7ca9f48cb)
