* 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
Any repeating crash that prevents a human from logging in and fixing
the config should be treated as a boot loop. Increase the detection
timeout, so anything that's fast enough to preclude a user fix will
trigger the recovery behaviour.
Don't treat consecutive but infrequent crashes as bootloops. The
bootloop recovery actions only make sense when there is no opportunity
for a user to reconfigure their system.

this fixes a very long loop when an overflow was happening in palette blending.
- reset prevPaletteBlends to prevent overflow
- add safety check in case overflow should still happen in another combination (or in future changes)
this new hooks will help you implement new and custom protocols in
usermods.
I've provided an example (see usermods/udp_name_sync).
The example will help you share the main segment name across different
WLED instances.
The segment name can be useful to sync with some effects like GIF
image or scrolling text.
If you define new packet format in your usermod, make sure it will
either not collide with already used version of wled udp packet :
- 0 is for udp sync
- 1 is for AudioReactive data
- 2 is for udp_name_sync :)
Also, the onUdpPacket will override "parseNotification" if it returns "true".
Have fun!
ESP8266 RTC RAM requires 32-bit accesses, but there's no need to jump
through a bunch of functions for it. Use references to simplify access
and harmonize the implementation with ESP32.
* Fix bootloop if config missing/reset
Can't reset the config if there's nothing to reset!
* ESP8266: Commit ACTIONT_TRACKER
* Use consistent naming for backups and reset cfgs
Use 'rst.cfg.json' instead of 'cfg.json.rst.json' for configs that were
reset.
* Add a little more PSTR to bootloop handling
The duplication of logic and the formatting differences between the "OTA Updates" and "Security & Updates" pages made it very difficult to find the exact version details.
With this change, both update-pages now share the same consistent and detailed formatting, making it easy for users to identify which exact version and binary of WLED they've installed.
The version format has also been improved to make it much easier to understand.
In the past, the "notify direct" flag controlled all network syncing, propagating all color changes to other devices on the network. Pressing the UI Sync button only toggled this flag, so "notify direct" was set to false by default.
In version 0.15, a separate "master" sync flag was introduced, and the UI Sync button now only activates this master flag. However, the rest of the flag defaults weren't configured to sync anything at all. As a result, users pressing Sync saw *no* syncing at all, leading to multiple bug reports.
Defaults are now user-friendly: Enabling Sync on a WLED device syncs all of *its* color changes, whether made via the UI, API or remote button, providing a consistent experience which matches the intended behavior from past WLED versions.
Philips Hue sync is now also disabled by default, making the stock defaults focused on WLED devices. Users with other RGB ecosystems can manually enable the Hue or Alexa syncing in the settings.
* added boot loop detection and config backup
* automatic OTA rollback if loading backup does not fix it
* added new file handling functions
* adding verification of json files, added config restore at bootup if broken
* added function to compare contents of two files for future use (currently not used)
* Make color_wheel rotate in HSV sapce instead of linearly interpolating R->G->B
* Remove the rainbow wheel option, as that is the same as the rainbow palette
* Use hsv2rgb for color_wheel
This is the current result of the discussion in https://github.com/wled/WLED/pull/3681
- Bugfixes in FX data allocation: realloc was not handled properly.
- Added *intermediate* fix for waitForIt(), see https://github.com/wled/WLED/issues/4779
- Bugfix in 1D->2D expansions: corner-expansion MUST be boundary checked as it blindly writes the max dimension
- removed some realloc(), improving fragmentation on large setups
- increased min heap constant
- ESP32 C3 has no PSRAM, it now uses default alloc functions
- also added missing UI info for "Error 7"
- using segment buffer instead of local buffer to save FX ram
- fix rendering if gamma correction is disabled
- some code cleanup
- Fix for low RAM: reduce number of particles dynamically
- updated add and scale color functions to not use references
- FPS is now more consistent and on average about 15% faster
* Added FX to copy a segment in 1D or 2D
- copies the source segment
- brightness of segment is relative to source segment
- optionally shifts the color hue, saturation and brightness
- invert, transpose, mirror work
- if source or targets do not match in size, smallest size is copied
- unused pixels fade to black (allows overlapping segments)
- if invalid source ID is set, segment just fades to black
- added a rgb2hsv conversion function as the fastled variant is inaccurate and buggy
- 1D to 2D and vice versa are supported
