* New Effect: Color Clouds
ColorClouds: Random start points for clouds and color
ColorClouds: new config option 'More red'
* ColorClouds: Incorporated review comments
- Support for color palettes
- Use perlin16() instead of inoise16()
- Use cos8_t() instead of cos8()
* ColorClouds: incorporated more review comments
* ColorClouds: incorporated final review comment
* switch-cases that fall through
* potential buffer overflow in improv.cpp
* potentially uninitialized variables in FX.cpp
* potential array out-of-range on segment::col[]
* minor optimization: only apply gamma correction when result is needed
* tag some possibly unused variables with [[maybe_unused]]
Introduces new memory allocation functions, based on wled#4895 by @DedeHai
* keep a minimum of 15KB RAM available to UI - improves stability
* S3/S2/C3 automatically use "fast RTC Ram" for small data (reduces fragmentation)
* auto-detects PSRAM (or no PSRAM) when firmware was built with -D BOARD_HAS_PSRAM
* d_malloc() and d_calloc() prefer DRAM if possible (faster), but fall back to PSRAM when free RAM gets low.
* make currentMode() inline
* move currentColor() to FX.h
* move Segment::color_wheel() and Segment::color_from_palette() to FX.h
* add a little helper function to fx.h, so it can access strip.paletteBlend which is not defined yet
* protect pixel buffer changes with critical section
* protect segment list modification with critical section
* make _isServicing and _triggered atomic (move out of packed bitarray)
* allow custom timeout for waitUntilIdle - DDP needs a longer timeout
* protect strip.show() and effect drawing functions with mutex, to prevent crashes
* added vLength(), vHeight(), vWidth() and mapped them to their WLED-MM counterparts
* added SEG_W and SEG_H macros
* minor variable renaming to avoid name clashes with vWidth, vHeight, vLength
Sends a shimmer across the strip at defined (or random) intervals
Optional brightness modulators: sine or perlin noise
Can be used as an overlay to other effects.
* centralize font selection logic into getFontInfo()
* removed unneeded parameter "numberOfChars" from drawText()
* new file: wled_fonts.hpp to centralize font management logic (inline)
* only compile wchar16ToCodepage437 when WLED_ENABLE_FULL_FONTS
* minor cleanup
- if a segment is destroyed or turned inactive, disable the gif player: only one gif player instance can run at a time, if a inactive or destroyed segment uses it, the effect is broken for other segments.
- copy FX ironically copied the source segment on each call, should use reference not a copy!
The segment copy constructors can temporarily exceed the budget of MAX_SEGMENT_DATA. The original segment will be de-allocated a few milliseconds later.
This change introduced an "overdraft" budget of 50% that can be used for temporary segment copies.
replaced CRGB -> RGBW32 conversion with FastLED native ``uint32_t(c) & 0x00FFFFFF`` operator. `
`& 0x00FFFFFF`` is needed to cut out the "alpha" channel, because the fastLED operator return RGBA not RGBW.
--> slightly faster
* moved sPC and gPC functions out of their .cpp files into FX.h, so the compiler can optimize better.
depending of effect used, this gives a 2% up to 8% speedup.
* 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
* made timing calculations work with large led counts
* improve randomness by injecting esp_random()
* ripple 2D: avoid ugly artifacts, by limiting circles to on-screen coordibnates
allows the compiler to inline access to ledsrgb[] , while still keeping the "no buffer" case in a separate function so program size does not blow up.
--> up to 10% faster
... transpose, mirror, reverse, grouping, spacing, size
* unlike AC WLED, when calling seg.fill(BLACK) from webserver context this usually has no effect --> added markForBlank() that shedules segment blanking at the next drawing cycle
* fill previous segment with black when size, grouping or spacing changes
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
constexpr ensures that the compiler will replace the "getter" call with the value return, saving function call overhead.
based on an idea from @blazoncek
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)
