- 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"
- 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)
- Implement vector in bus manager
- Memory calculation according to explanation from @Makuna
- Prefer 8 RMT before 8 I2S on ESP32 (fixes#4380)
- speed improvements in ABL
- verbose debugging
- get bus size from NPB (prototype)
- Parallel I2S output bugfix
- automatic selection of appropriate I2S bus (`X1xxxxxxMethod`)
- removed I2S0 on ESP32 (used by AudioReactive)
- renumbered internal bus numbers (iType)
- added buffer size reporting
* 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
- code is a bit cleaner and faster as well
- chaning array access to pointer access in bus_manager makes it a few instructions faster
- changed getNumberOfPins and getNumberOfChannels to return 32bit values, saving the unnecessary 8bit conversion
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.
Use the phase-locked soft PWM from the Arduino core to implement the
same PWM phase management as ESP32s are using. The soft PWM code is
vendored in, as it was previously, to add the NMI workaround from #4035.
Completes #4034
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.
