* 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.
* use native 32bit types (similar to upstream)
* avoids gaps on left/right side of strip, by using higher accuracy for zoneLength
* prevent overflow on "s"
* fix wrongly named slider in "spots fade"
* 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
-> distortion waves 3x speedup
-> hiphotic 2x speedup
-> waving cell 1.5x speedup
* replace sin8_t by lookup-table with pre-computed values
* moved integer sin and cos to fcn_declare.h (inlined by the compiler)
* moved gamma32 to fcn_declare.h (inlined by the compiler)
* a few other small tweaks
* 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
- fixed "jumpyness" by improving offset calculation resolution
- added palette support
- added two rendering modes for use with palette: one uses hue-mapping, one uses brightness mapping
- added alternate animation mode (from initial source)
- extended scaling: zoom checkmark (depends on matrix size)
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
* introducing WLED_MAX_SEGNAME_LEN from upstream
* default: max name length = 48
* hopefully found all places where the segment name length was hardcoded (32, 33, 34)
* some comments still refer to "32" but wtf
* fixed a bug that caused wrong behavior with segment mirroring
(effects must use virtualHeight() / virtualWidth() instead of height() / width())
* added image blur as an option (second slider)
* added very basic error reporting for users
* up to 25% faster, especially with big animated gifs
* made all local variables "static" (don't pollute global namespace)
* drawPixelCallback: cache calculation that do not depend on x/y position
* reduced memory allocations on boards without PSRAM, to avoid crashes
For maintainers of custom effects: replace "return mode_solid()" with "return mode_oops()"
Effect errors fall back to Akemi (2D) or Rainbow(1D) instead of SOLID ORANGE.
- fixed inconsitencies in size rendering
- fixed palette being wrapped in color by position and color by age modes
- Fixed bug in memory layout: for some unknown reason, if flags come before particles, last flag is sometimes overwritten, changing memory laout seems to fix that
- New color modes in PS Fireworks 1D:
- custom3 slider < 16: lower saturation (check1: single color or multi-color explosions)
- custom3 slider <= 23: full saturation (check1: single color or multi-color explosions)
- custom3 slider > 23: color by speed (check 1 has not effect here)
- custom slider = max: color by age or color by position (depends on check1)
- removed local buffer for ESP8266 in 1D system to save on RAM
- increased particle brightness in PS Impact
- minor tweak in collision binning (might improve speed)
- removed comments and some other unused stuff
- fixed a few compiler wranings
