if random palette was used in the startup preset, all LEDs were orange until the first palette cycling happened.
This fix ensures that there is no all-orange palette initially.
I've found a code spellchecker, so this is what can be corrected easily. Changes are only affecting comments, readme and a few user-visible strings. So no functional impact expected.
index.js
- genPresets: Temporary for deterministic effects test: Set to 11/Raibow instead of 1/Random smooth palette
FX.cpp
- replace all millis() by strip.now
cleanup:
- version increase
- clean up debug messages
- minor fixes in platformio.ini
- fix compilation with -D WLED_DISABLE_2D
helping the compiler to optimize:
- a few more __attribute__((pure))
- fx.cpp marked a few local functions as "static"
Segments are created/deleted on-the-fly; it seems that "local leds" buffers did not follow properly.
* revise segment copy/move constructors
* de-optimize use of local leds (as they need to be re-allocated when segment size changes)
* minor stability improvements
it seems that SEGMENT.blur() is the main bottleneck for many 2D effects.
This change optimizes performance of the function:
* avoid to re-write unchanged pixels
* early exit when blur_amount == 0 (=nothing to do)
* use _fast_ types where possible
I've seen up to 20% speedup with this change.
power estimation results from estimateCurrentAndLimitBri() were too low (example: estimated 1.3Amp, measured 1.6Amp). This change corrects the power calculation. Due to the changed behavior of getPixelColor, powerSum must be used as-is, not scaled down again by brightness.
this optimization avoids to apply brightness two times .
NeoPixelBusLg has already applied global brightness at sPC. Due to internal working of the Lg bus, its sufficient to only post-apply scaling, and set the new (scaled) brightness for the next frame.
* adding an optional parameter to setBrightness(). ApplyPostAdjustments() will only be called if `immediate=true`. Only ABL will use immediate=true, to ensure electrical safety of equipment.
This allows some optimizations of performance, as ApplyPostAdjustments() is time consuming.
* busses.setBrightness(bri) --> applied to all future pixels (fast, lossless)
* busses.setBrightness(bri, true) --> applied directly to all previously set pixels (slower, lossy)

* handling of stop = 0 when calculating sizes (avoid unsigned underflow)
* make sure groupLength() is never zero (to avoid div/0)
* gapmaps: check for "(gapSize > 0)" added.
not sure if all the checks are 100% needed, but they will improve robustness in corner cases.
* Avoid uint16 underflow in width() and height(): stop > start is possible, and means "inactive segment".
* use size_t for ledsrgbSize, _dataLen and _usedSegmentData - uint16_t could overflow in some situations.
* try to catch attempts to allocate zero bytes (inactive segment => size 0)
This disables parts of the new feature that might lead to delays, so basicially there is some detection, but no protection any more.
further development needed --> audio_fastpath branch
compile with -D WLEDMM_PROTECT_SERVICE to enable full protection.
* Changes for allowing Alexa to change light color to White when auto-calculating from RGB
* Update alexa.cpp
Indention
* Do not rely on global auto white override
(gets white mode from segment light capabilities)
* alexa.cpp: Removed unnecessary whitespaces
