- sin/cos calls with incrementing numbers can lead to bad outcomes, the functions (_approx or original sinf/cosf) return bad values for very large float inputs
- code is a bit cleaner and faster as well
- chaning array access to pointer access in bus_manager makes it a few instructions faster
- changed getNumberOfPins and getNumberOfChannels to return 32bit values, saving the unnecessary 8bit conversion
NeoPixelBus requires that all parallel I2S bus members be constructed
before any of them call Begin(). Implement this by deferring the
call to the end of bus construction.
Fixes#4301.
- all palettes are defined in palettes.h
- access to fastled palettes as an array to remove the switch cases
- palette createn in json.cpp in a loop instead of repeaded calls to save flash
- rotation scale is now exactly 180° (divide slider input by 255 instead of 256)
- removed shift offset: offset is now zero at slider 0, to hit 128 on touch input devices is really hard
- added a 90° shift to input rotation, enabling to rotate from 0 to 180° instead of +90 to -90 (which is not useful in 1D)
- changed default settings values to more closely match the old 1D effect
Fixed point calculation for improved accuracy, dithering in debug builds only.
Averaging and optional multiplier can be set as compile flags, example for speed testing with long averaging and a 10x multiplier:
-D FPS_CALC_AVG=200
-D FPS_MULTIPLIER=10
The calculation resolution is limited (9.7bit fixed point) so values larger than 200 can hit resolution limit and get stuck before reaching the final value.
If WLED_DEBUG is defined, dithering is added to the returned value so sub-frame accuracy is possible in post-processingwithout enabling the multiplier.
* keep FRAMETIME_FIXED as a fixed value
* remove WLED_FPS_SLOW and FRAMETIME_FIXED_SLOW
* explicit test "(_targetFps != FPS_UNLIMITED)" for debug messages
* don't modify _lastServiceShow in show()
* test for "fps == FPS_UNLIMITED" explicitly, so we could pick a different
magic number later
* separate fps calculation (strip.show) from framerate control (strio.service)
* improved condition for early exit in strip.show
* make MIN_SHOW_DELAY depend on target fps
* strip.show consideres complete time for effect calculation + show; old code wrongly used the time between completion of last show and start of next effect drawing, causing unexpected slowdown
* add "unlimited FPS mode" for testing
* increase warning limits for "slow strip" and "slow effects"
- increase WLED_MAX_BUSSES for C3 (fixes#4215)
- fix for #4228
- fix for very long running effect (strip.now, strip.timebase)
- C++ API change to allow `seg.setColor().setOpacity()`
Fix for LED and Scenes uncontrollable using Alexa.
Weird behavior regarding to the device names and shared scenes fixed with this.
Seen in issue Aircoookie/Espalexa#228 and fixed from @ams-hh
Tested by myself and works just fine. Created second pull request here because the library seems to be a bit different from the official Espalexa repo.

-replaced all PI references with M_PI version
-there is no need to do the angle-modulo in float, casting it to an integer does the same BUT it has to be cast to an `int` first, see comment.
* fixed the positioning of the download button
* fixed space after "Download the latest binary:" disapering after building
* fixed typo

- `sin16_t() / cos16_t()` are faster and more accurate than fastled versions
- `sin_approx() / cos_approx()` are float wrappers for `sin16_t() / cos16_t()` and are accurate enough to replace `sinf()/cosf()`
- `atan2()` is used only in octopus to calculate center offset, new approximated version saves flash
- `tan(), atan(), asin(), acos(), floor(), fmod()` are used only for sunrise/sunset calculation, using wled_math version saves flash
- `beatsinx()` replacements are to make use of new `sin16_t()/sin8_t()` functions to reduce flash size
- Extensively tested surnise/sunset calculation: deviation is 1min. max
- Tested some of the relevant FX and found no visual difference: Julia, 2D Drift, Drift Rose, Ghost rider, Rotozoomer, Palette, Arc 1D expansion
- total flash savings: 7.4k
- changes to `setPixelColorXY` give an extra FPS, some checks and the loops are only done when needed, additional function call is still faster (force inlining it gives negligible speed boost but eats more flash)
- commented out the unused `boxBlur` function
- code size improvemnts (also faster) in `moveX()` and `moveY()` by only copying whats required and avoiding code duplications
- consolidated the `blur()` functions by enabling asymmetrical blur2D() to replace `blurRow` and `blurCol`
- compiler warning fixes (explicit unsigned casts)
