* it seems that `WiFiUDP.flsuh()` does something completely different from 8266, and its actually causing WLED to stall on UI calls. So not usable on 8266.
* fixing a few compiler warnings about "comparing signed and unsigned"
NB: its a hotfix, we have to check if there are other problems on 8266. Also its definitely ugly, but it helps as a band aid.
- you need to install the bootloader from platformio build folder
- only for "opi" (octal) PSRAM; will not work with "qspi" (quad) PSRAM (2MB or 4MB)
-small cleanups for -S3/-S2/-C3 environments
cleanup:
- version increase
- clean up debug messages
- minor fixes in platformio.ini
- fix compilation with -D WLED_DISABLE_2D
helping the compiler to optimize:
- a few more __attribute__((pure))
- fx.cpp marked a few local functions as "static"
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
it seems that SEGMENT.blur() is the main bottleneck for many 2D effects.
This change optimizes performance of the function:
* avoid to re-write unchanged pixels
* early exit when blur_amount == 0 (=nothing to do)
* use _fast_ types where possible
I've seen up to 20% speedup with this change.
power estimation results from estimateCurrentAndLimitBri() were too low (example: estimated 1.3Amp, measured 1.6Amp). This change corrects the power calculation. Due to the changed behavior of getPixelColor, powerSum must be used as-is, not scaled down again by brightness.
this optimization avoids to apply brightness two times .
NeoPixelBusLg has already applied global brightness at sPC. Due to internal working of the Lg bus, its sufficient to only post-apply scaling, and set the new (scaled) brightness for the next frame.
