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()`
- 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)
