Removing the bool saves on code size and makes the function a tiny bit faster. Also this is a cleaner solution IMHO.
-updated blend function to optimized 8bit calculation
- efficient color blend calculation in fews operations possible
- omitting min / max checks makes it faster on average
- using 8bit for "blend" variable does not significantly influence the resulting color, just transition points are slightly shifted but yield very good results (and better than the original 16bit version using the old fastled math with improper rounding)
- updated drawCircle and drawLine to use 8bit directly instead of 16bit with a shift
Processing of received button command is no longer processed in the callback, instead the value is saved to a variable and processed in the main loop.
The actual fix is to not access the file system while data is being sent out: even just trying to open a non-existing file causes glitches on the C3. Waiting for the bus to finish fixes this BUT it causes a frame-delay which is the lesser evil than random color flashes.
- 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()`
- `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
uint16_t to unsigned to make it consisten throughout the hand-down.
colorFromPaletteWLED now returns uint32_t which saves the conversion to CRGB and back to uint32_t (in most uses at least).
also added (preliminary) CRGBW struct. I tried to use it in place of uint32_t colors but it adds a lot of overhead when passing the struct so reverted to uint32_t in most places.
updated a few FX to use the CRGBW struct and also cleaned some code to improve flash useage.
- also added a struct to handle HSV with 16bit hue better (including some conversions, can be extended easily)
- the functions are optimized for speed and flash use. They are faster and more accurate than what fastled offers (and use much less flash).
- replaced colorHStoRGB() with a call to the new hsv2rgb() function, saving even more flash (new function is untested!)
- the 16bit hue calculations result in an almost perfect conversion from RGB to HSV and back, the maximum error was 1/255 in the cases I tested.
- blurring now uses desaturated adding: it is faster most of the times and blurring adds scaled colors so should rarely (ever?) saturate, I saw no visual difference in tests.
- formatting
Remove the large stack buffer as we're just going to copy it in to a
heap buffer anyways. Later we can refine the length estimation or use a
rope-style dynamic data structure like DynamicBufferList.
- optimized color_add() again: now it is as fast with preserved ratio scaling than the "fast" variant was before (if no scaling is needed, it is even faster). plus it saves 250 bytes of flash
- bugfix in `color_fade()`
- removed a lot of whitespaces
- transitions always enabled (use delay 0 to disable)
- optimisation in on/off fade
- fix for palette/color blend when blending style is not fade
- various tweaks and optimisations
-added fully random palette function ('the old way', currently just used for initialization)
-changed randomness values to make it a little less random
-added 10% chance for pastel color palette
-now using swap() from std library for shuffeling
-changed function name
-moved update check from loadPalette() to handleRandomPalette() saving CPU cycles
Add JSONBufferGuard, an RAII lock guard class for JSONBufferLock
analogous to std::lock_guard. This permits binding the guard to a scope,
such as an object life cycle or function body, guaranteeing that the
lock will be released when the scope exits.

* add 9 further alexa devices for calling presets 1-9
* use preset names from WLED for Alexa preset device names instead of hardcoded names
* update readme and version
* call alexaInit() at end of savePreset() to keep Alexa in sync with the preset IDs and names
* This reverts commit f8db06c7c5.
* change order to configured Alexa WLED name first, preset names afterwards
* fix status of devices when shown within Alexa, i.e. switching one preset on switches others off (except for alexaInvocationName)
* re-add getPresetName() after merge with master
* restore original readme for pull request
* restore original platformio.ini for pull request
* Logic simplification
* Pass string by reference
* Added number of presets check
* fix alexaInit() in case of alexaNumPresets==0
