* updated color scaling to preserve hue at low brightness resulting in much better colors
* replace NPBlg with NPB, moved brightness scaling to bus manager
* improved gamma table calculation: fixed mismatch in inverting gamma table calculation: inversion should now be as good as it gets
* code cleanup, fixed gamma being applied in unnecessary places
Improvements to ABL handling:
- removed strip level handling, ist now all done on bus level
- limiter now respects pixel mapping
- proper handling of white channel
- improved current estimation
- current is now always correctly reported to UI
- minimal FPS impact if the ABL is not limiting but slighly higher impact for global ABL limit due to double-scaling
- moved brightness scaling to BusDigital
- created new header file colors.h to be able to access color functions in bus-manager.
- updated colo_fade() with better video scaling to preserve hue's at low brightness
- added IRAM_ATTR to color_fade (negligible speed impact when compared to inline and benefits other functions)
- added IRAM_ATTR to color_blend as it is used a lot throughout the code, did not test speed impact but adding it to color_fade made it almost on-par with an inlined function
Additional changes:
- fixes for properly handling `scaledBri()` (by @blazoncek)
- also use bit-shift instead of division in blending for ESP8266
- improvements for faster "softlight" calculation in blending
- changed some variables to uint8_t to maybe let the compiler optimize better, uint8_t can be faster if read, store and set are all done in uint8_t, which is the case in the ones I changed
- various minor code formatting changes
- Photoshop-style segment/layer blending
- return of strip ABL
- remove global LED buffer in favour of segment-local buffer
- new effect blending modes/transitions
- custom palettes moved out of WS2812FX class
- increased limits (matrix size, LED RAM)
- added "rainbow"-mode colorwheel
- replaced palettes with gamma unmodified ones
- move gamma adjustment to last step before sending to LEDs
- Segment & WS2812FX class reorganisation (mutable members, reordered members, protected members)
Rather than reading the file off disk, have the json/cfg endpoint
return the live config from system state data. This can improve
UI behaviour as it can never be out of date or include values that
do not apply to the current firmware install.
Part of the ongoing quest to migrate macro definitions to typed
language constructs. This actually yields a small improvement in
code size, likely from the byte->int conversion.
* changed some parameters to "pointer to const", so compiler can better optimize code size and performance - because data behind a const pointer will never be modified by the called function.
* made setPixelColor `const`
* fixed a few potentially uninitialized local vars (the may have random values if not initialized)
* avoid shadowing "state" in handleSerial()
* plus a few very minor improvements
* make XY() and _setPixelColorXY_raw() const (minor speedup)
* segment is a struct not a class: friend class Segment --> friend struct Segment
* fix missing braces around two macros
* use non-throwing "new" where possible
* improve robustness of transition code
- 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
- 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()`
- edit WiFi TX power (ESP32)
- keep current ledmap ID in UI
- limit outputs in UI based on length
- wifi.ap addition to JSON Info
- relay pin init bugfix
- file editor button in UI
- several compile warning fixes
- multipin LED compile config
- release info (update page, JSON "info")
- WiFi scan fix if no networks found
- UI glitch when no presets are found fix
With multipin LED config it is now possible to assign GPIO to PWM RGB outputs.
Achieved by having length of DATA_PINS be divisble by lengt of PIXEL_COUNTS.
- 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
