* Improved heap and PSRAM handling
- Segment `allocateData()` uses more elaborate DRAM checking to reduce fragmentation and allow for larger setups to run on low heap
- Segment data allocation fails if minimum contiguous block size runs low to keep the UI working
- Increased `MAX_SEGMENT_DATA` to account for better segment data handling
- Memory allocation functions try to keep enough DRAM for segment data
- Added constant `PSRAM_THRESHOLD` to improve PSARM usage
- Increase MIN_HEAP_SIZE to reduce risk of breaking UI due to low memory for JSON response
- ESP32 makes use of IRAM (no 8bit access) for pixeluffers, freeing up to 50kB of RAM
- Fix to properly get available heap on all platforms: added function `getFreeHeapSize()`
- Bugfix for effects that divide by SEGLEN: don't run FX in service() if segment is not active
-Syntax fix in AR: calloc() uses (numelements, size) as arguments
* Added new functions for allocation and heap checking
- added `allocate_buffer()` function that can be used to allocate large buffers: takes parameters to set preferred ram location, including 32bit accessible RAM on ESP32. Returns null if heap runs low or switches to PSRAM
- getFreeHeapSize() and getContiguousFreeHeap() helper functions for all platforms to correctly report free useable heap
- updated some constants
- updated segment data allocation to free the data if it is large
- replaced "psramsafe" variable with it's #ifdef: BOARD_HAS_PSRAM and made accomodating changes
- added some compile-time checks to handle invalid env. definitions
- updated all allocation functions and some of the logic behind them
- added use of fast RTC-Memory where available
- increased MIN_HEAP_SIZE for all systems (improved stability in tests)
- updated memory calculation in web-UI to account for required segment buffer
- added UI alerts if buffer allocation fails
- made getUsedSegmentData() non-private (used in buffer alloc function)
- changed MAX_SEGMENT_DATA
- added more detailed memory log to DEBUG output
- added debug output to buffer alloc function
Pull the RMT High-priority Interrupt driver in to a vendored local
library, pending inclusion in upstream NeoPixelBus.
Driver is enabled only for XTensa chips; there's some unresolved
issue with nested interrupts on RISCV.
* 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.
Suggested by @coderabbitai
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"

- 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
* enhancement & bugfixes in scrolling text
- function now evaluates full string: allows custom text plus multiple tokens in any order
- fixed evaluation order to prevent early exit(s)
- fixed day strings (argument must be weekday() )
- prevent settings change if not using private IP address or same subnet
- prevent OTA from differnet subnet if PIN is not set
- ability to revert firmware
the compilation fails with tons of errors if you try to compile using WLED_DISABLE_2D
"message": "enclosing class of constexpr non-static member function 'bool Segment::is2D() const' is not a literal type",
"LineNumber": 766,

Particle System depends on linear brightness distribution, gamma corrected values are non-linear.
- added invers gamma table
- reversing gamma after brightness distribution makes it linear once again
- fixed "jumpyness" by improving offset calculation resolution
- added palette support
- added two rendering modes for use with palette: one uses hue-mapping, one uses brightness mapping
- added alternate animation mode (from initial source)
- extended scaling: zoom checkmark (depends on matrix size)
Correct issues with usermods not being linked.
- Explicitly set libArchive: false in usermod library.json files
- Fix up symlink path generation on Windows
- Add validation script to report usermod linkage in resulting binary
- prevent settings change if not using private IP address or same subnet
- prevent OTA from differnet subnet if PIN is not set
- ability to revert firmware
Neither the info panel nor the settings dialog can be trusted to
accurately report the usermod list:
- Not all usermods necessarily add to the info panel
- Not all usermods necessarily add to the config page
- #4609 is required for the config page to be correct
Add a short list to the info object that lists the loaded usermod IDs.
This is not displayed via the UI, but can be queried with curl or web
debug tools.
To be removed when usermod loading is working well.

- fixed palette being wrapped in color by position and color by age modes
- Fixed bug in memory layout: for some unknown reason, if flags come before particles, last flag is sometimes overwritten, changing memory laout seems to fix that
- New color modes in PS Fireworks 1D:
- custom3 slider < 16: lower saturation (check1: single color or multi-color explosions)
- custom3 slider <= 23: full saturation (check1: single color or multi-color explosions)
- custom3 slider > 23: color by speed (check 1 has not effect here)

- HTTP OTA updates can be blocked using PIN or OTA lock
* added Sonic Boom AR FX, some tweaks to Sonic Stream
* added white color option to Sonic Stream
* improvements to collisions (speed look-ahead)
* code prettified
* added "playful" mode to PS Chase plus some minor speed optimizations
* Adding new FX: PS Springy with many config options
Several of our controllers support the Ethernet module, so we figured it best to leave it as simply "RGB2Go" in the menu, as opposed to "RBG2Go" Tetra.
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.
Break the actual JSON assembly apart from the file writing code. This
permits calling it in other contexts, allowing us to pull the live
config data even if the filesystem is out of date.
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.

- removed 2D buffers, replaced with 1D buffer for faster access
- bugfix in blur2D
- many small improvements to 2D system
* Refactoring and cleanup of 1D PS, removed debug printouts
- code reformating for consistency and readability
- replaced "'?" operator with min / max (produces the same code, more readable)
- minor changes for speed (random16 used, can later be replaced with hardware random function)
- renamed PS Equalizer to PS 2D GEQ
* Cleanup and some refactoring of particle FX
- moved 2D / length check to PS initi
- code reformating
- removed some comments
* missed a spot
* minor tweaks to fast_color_add()
* Work in progress: update to fireworks, needs more testing & finetuning
also bugs fixed and some minor cleanup
* Work in Progress: added particle memory manager for transitions
- uses only one, persistant buffer to render all present particle systems
- Buffer for particles is shared for one segment (may allow interacitng systems in the future)
- updated some of the FX to handle the new transfer, 1D FX still not done
- updated parameters for particle impact FX
* work in progress: lots of changes & fixes, transitions now work correctly in 2D
- still fragile code with lots of cleanup to do
* added transitions for big-size rendering
- transitions now work with FX that use global large size rendering. this is done by handling the buffer correctly. to avoid creating a second buffer, it is transferred back and forth to the segment. this is a bit slow but a compromise solution.
- multiple segment handling is still untested
* speed improvement to fast_color_add, added preliminary buffer transfer function
* merge fixes
* bugfix in setCurrentPalette, corrected order of 2D memory allocation, increased max particles/sources
- fixed timing for vortex
* fixed particle buffer handover, added 2D blur option, increased particle limits, various fixes
- fixed bug in memory watchdog, now works and also works when freezing segments
- fixed PS Box to work again with particle handover
- added smear blurring to waterfall
- added smear blurring to vortex, fixed color distribution, removed random color distribution option
- replaced all random() calls with hw_random()
- transitions now work but only if FX transitions are enabled and not when chaning segment size
* implemented correct 1D<->2D buffer handover+bugfixes
work in progress
* added smear to fuzzy noise, some cleanup
* added blurring option to PS 2D fireworks, work in progress in finding that nasty bug that crashes all
* BUGFIX: finally found and squased the memory bug, no more random crashes
also: removed debug outputs and minor cleanup
* minor cleanup and fixed a bug
1D system had a lot of crashes, some out of bounds memory issue. fixed it but I have no idea which change did that, maybe the order in 1D initialization
* BUGFIX: out of bounds checking was wrong, leading to crashes
* better handling of used particles in transitions
for FX that do not use all particles, transitions were constantly shifting the pointer, resulting in newly generated particles and weird particle flickering, this is not fixed by keeping the pointer constant once the number of used particles is reached.
* improved particle transition for low-count FX, updated 1D FX
now most 1D FX work again, still needs some fine-tuning
* Rework on Fireworks 1D, some minor fixes
- fireworks 1D now matches as closely as possible to the old FX
still not identical but as good as it gets.
* bugfix in PS Chase, increased brightness of 1D fireworks
* replaced sin16/cos16 with new versions
* bugfixes
* fixed hourglass init, rearranged PS FX init
* speed optimization
- moved out of bounds calculation to proper spot
- removed repeated allocation attempts if initial buffer alloc fails
* Added Sonic Stream FX, some cleanup, bugfix in emitter
* changed TTL to brightness calculation, added collision binning
- brightness is now doubled as some FX were really dim due to low TTL
- added binning in x-direction giving a huge speed advantage on larger matrix sizes
* collision binning bugfix, made particles less sticky, update to waterfall
- updated waterfall intensity and blurring
* WIP: fixed 1D system for over 1000 pixels, added collision binning for 1D
- making x coordinate 32bit allows for larger strips but uses a lot of ram due to struct memory alignment (12bytes instead of 8 bytes), this needs some more work to properly fix.
- adding collision binning significantly speeds things up, about a factor of 2 on most FX using collision
- there are still some bugs in FX or 1D memory handling (or both) on large setups
* moved particle flags to seperate array to save on RAM, refactoring
- moving the flags optimizes ram alignment, saving memory for each particle
- changed lots of parameters to `const`
- moved fire intensity to a variable instead of passing it to every render() call
- changed passing pointers to passing reference where possible
- saves a total of 340 bytes of flash
* removed todos after some checks, minor improvements
* inverted y axis in 2D render, 1D collision improvements, cleanup and fixes
- inverting the y-axis in the buffer instead of in buffer transfer fixes the FX flipping when transitiononing 1D<->2D
- improved particle binning for collisions
- added hard-pushing also when not using gravity so piles close to an edge dont collapse
- some improvments to "balance" FX
- renaming and cleanup
* FX fixes and minor tweaks
* increased min rockets
* fixed #ifdefs
* another fix
* revert unnecessary changes to base code
* merge fix
* minor tweak
* tweaked sparkler FX, some cleanup
* Fix in volcano FX, changed blurring of volcano and waterfall
* added ifdefs
* minor tweaks, increased 1D minsurfacehardness
* improved sparkler FX, made overlay possible (1D not yet), cleanup
* cleanup, now using new hsv2rgb/rgb2hsv, add overlay rendering to 1D
- new hsv2rgb is a tiny bit faster
- removed redundant code (using transferBuffer instead)
- tweked parameters in vortex, removed unneeded slider defaults
* fix for non or partially overlapping segments
- can not use overlay rendering if no segment clears the buffer, it will all add up to white eventually
- now additive transfer i.e. overlay mode is only activated if the segment is fully overlapping an underlying segment
* change got lost...
* increased sparkler intensity, some cleanup
* replaced #ifdefs, removed 1D replacements that have 2D version, removed notes
* cleanup, improvements to PS bouncing ball, replaced multicomet
- bouncing balls is now named pinball and has settings/parameters updated to be a replacement for multicomet
* cleanup, improvements, bugfixes
- large size rendering now works without framebuffer
- background adding is now done on buffer (if avilable) instead of segment
- fixed overflow bug in 2D large particle rendering (it worked only for powers of 2 size)
* potential bugfix, compiler warning fix
* removed colorwaves and pride option from chase (not worthy replacements)
* updated #defines, removed PS from 1M and 2M builds

* merge fixes
* added single pixel particle rendering for 2D system, adjusted FX to work with it
* improved collisions in 1D and 2D, some bugfixes in radius calculation, minor tweaks
- collisions are now also velocity based in 1D, there was a bug that prevented that from working well (wrong collision distance calculation)
- improvement and bugfix in 2D collision distance calculation
- added distance based pushing in 2D (instead of only using the dotproduct)
the combination of improved distance calculation and proper pushing make collisions a lot better in all tested FX
* minor fix
* fixed overlay detection, checking for partial overlay
if a PS FX is partially overlapping, it will render in overlay mode
* better blur range in PS Firworks
* minor code consolidation
* updated 1D collisions (yet again), improved 2D collision speed
- slight improvement to 2D collision code efficiency
- added faster "division" to C3/ESP8266 by using a right shift trick (biasing towards 0 also for negative numbers by applying proper rounding)
* minor tweak in PS balance
* fix for #4153
* only load touch/mouse events for touch/mouse devices
* undid formating changes
* undid more formating changes
* undid all formating changes
* use pointerover and pointerout eventlisteners
- moved local variables into function
- made coordinates an array
- amplitude can now be changed by user (default setting is a slight increase to original which cannot be avoided without complicated logic or default slider setting)
- fixed issue: blending was also done when color was on a key-index-color which is now skipped
- speed improvement: conversion is skipped if color is key-color
