Improvements & merges of FX
- Scrolling Text: Gradient Palette support added
- Waving Cell: Improved with higher temporal resolution (smoother at lower speeds) and added additional mode setting and optional blurring
- Julia: added blur option
- Squared Swirl: added fade option
- Added smearing option to:
- DNA
- DNA Spiral
- Drift
- Drift Rose
- Crazy Bees
- Ripple
- Colored Bursts
- Frizzles
- Lissajous
- Sindots
- Spaceships
- Added palette support to:
- Crazy Bees
- Polar Lights
- Drift Rose
- Changed default palette handling (no more special treatment for some FX)
- Merged puddles and puddlepeak
- Merged Gravcenter, Gravcentric, Gravfreq and Gravimeter (saves 1.2k of flash)
- Merged meteor and meteor smooth
- Renamed police_base into mode_two_dots as that was just an alias
- Added 'Traffic Light' palette (originally defined in Polar Lights FX)
- Firenoise: removed local palette, use fire palette -> slight change in looks (+bugfix)
- Some code cleanup (removed unused / commented stuff)
- Moved dev info for AR to the top so ist easier to find as a reference, also added link to KB there
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
progress() is called in setPixelColor(), calculating the transition progress for each pixel. Replaced that call with an inline function to get the new segment variable.
The progress is updated in service() when handleTransition() is called.
The new variable is in a spot where padding is added, so this should not use more RAM.
Result: over 10% increase in FPS on 16x16 matrix
* removed IRAM_ATTR: `updateTransitionProgress()` is called only once per frame, no need to put it in RAM.
* changed transitionprogress to static, private variable, this is now more aligned with other variables using the same logic
* added inline: the function is only used in one place
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
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()`
- 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)
- removing WS2812FX::setMode()
- removing WS2812FX::setColor()
- removing floating point in transition
- color handling modification in set.cpp
- replaced uint8_t with unsigned in function parameters
- inlined WS2812FX::isUpdating()
- (MAY BE BREAKING) alexa & smartnest update
- Added pre-calculation for segment brightness: stored in _segBri. The impact on FPS is not huge but measurable (~1-2FPS in my test conditions)
- Removed `bool unScaled` from `setPixelColor()` function again (it has no/minimal impact on speed but huge impact on flash usage: +850 bytes)
- Removed negative checking in `setPixelColorXY()` and replaced it with a local typecast to unsigned, saves a few instructions (tested and working)
- Changed int8_t to int in `moveX()` and `moveY()`
- Removed a few functions from IRAM as they are now not called for every pixel but only once per segment update
- Removed a `virtualWidth()` call from `ripple_base()`
- Bugfix in `mode_colortwinkle()`
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.
- 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
- 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
- gamma correction only where needed
- paletteIndex should be uint8_t (it is only used as that)
note: integrating the new `ColorFromPaletteWLED()` into this would require a whole lot of code rewrite and would result in more color conversions from 32bit to CRGB. It would be really useful only if CRGB is replaced with native 32bit colors.
inlining getMappedPixelIndex gets rid of function entry instructions (hopefully) so it should be faster.
also added the 'multi color math' trick to color_add function (it will not make much difference but code shrinks by a few bytes)
- Renamed LEDPIN to DEFAULT_LED_PIN.
- Removed ability to override DEFAULT_LED_PIN, DEFAULT_LED_TYPE and DEFAULT_LED_COUNT. Use DATA_PINS, LED_TYPES and PIXEL_COUNTS instead.
some users have reported that releases after 0.14.0 are not working reliably. So we add a few "compat" for 8266 that try to reproduce the buildenv of 0.14.0 as much as possible.
* platform and platform_packages from 0.14.0
* not using PIO_FRAMEWORK_ARDUINO_MMU_CACHE16_IRAM48
* due to smaller IRAM, we had to move some functions back from IRAM to normal flash (may cause slowdown)
