Segments are created/deleted on-the-fly; it seems that "local leds" buffers did not follow properly.
* revise segment copy/move constructors
* de-optimize use of local leds (as they need to be re-allocated when segment size changes)
* minor stability improvements
* handling of stop = 0 when calculating sizes (avoid unsigned underflow)
* make sure groupLength() is never zero (to avoid div/0)
* gapmaps: check for "(gapSize > 0)" added.
not sure if all the checks are 100% needed, but they will improve robustness in corner cases.
This disables parts of the new feature that might lead to delays, so basicially there is some detection, but no protection any more.
further development needed --> audio_fastpath branch
compile with -D WLEDMM_PROTECT_SERVICE to enable full protection.
*This patch allows to compile with BOARD_HAS_PSRAM, but not set WLED_USE_PSRAM - reserved pins will be protected, and PSRAM usage will be shown in info.
* if you add `-D WLED_USE_PSRAM_JSON` then PSRAM will be used for some JSON buffers, but not for LEDs and Segments.
the root cause of the crash is not really clear, as the problem seems to occur randomly, mosr frequent with fresh installations.
This workaround prevents the array bounds violation, by re-using the last valid gGradientPalettes entry.
* Info page: status of Serial (can be disconnected on new MCUs), and owner of RX/TX pins
* improved handling of Serial (don't write if not connected)
* added min available stack size to debug output (esp32 only)
* webserver show remaining stack size
* webserver: show string buffer usage
- athom_music_esp32_4MB_M bin
- show flashsize in info tab and /getflash
- support of their ir-remote (24-key music)
Not supported yet
- mac addres in AP name (need to experiment with WLED_AP_SSID_UNIQUE)
One pixel segment handling.
- added 0D FX metadata (1 pixel effects)
- ignore palettes for White only segment
- ignore color for non-RGB & non-White segment (on/off)
Bugfix
- proper auto segment creation
- hide palettes for non RGB segments
- some tweaks for #2984
- force Solid for some FX (causing crash) on 1 pixel segment
UI Optimisations
- slider tooltips
- tiny bit smaller tooltips
- hide segment power if only one segment
- gap between sliders
