* getpixelcolor: attribute pure - it reads memory, but does not write
* some optimizations for SEGMENT.blur() and SEGMENT.fadeToBlackBy()
* FX.c:pp remove double calls to blur() and fade_out()
* FX.cpp: SEGMENT.setUpLeds() added to effects, to enable LED buffering (safe some time because getPixelColor does not need to access NeopixelBus)
* a few other optimizations to safe time and avoid "expensive" operations
* set I2C bus speed to 400kHz (default is 100Khz)
* a few other small optimizations and tweaks
* pio: esp32 V4 builds use "patch5" toolchain version, which contains a few bugfixes especially for memory management.
use 4 RMT channels, then I2S#1, then RMT 5-8. This allows to have up to 5 "fast" LED pins.
"Even though the ESP32 has 8 channels of RMT hardware, using beyond 4 has shown to cause sending delays." (https://github.com/Makuna/NeoPixelBus/wiki/ESP32-NeoMethods#rmt)
* make local functions "static"
* use fast_ int types where possible
* use native min/max instead of MIN/MAX macros. Macros evaluate each parameter TWICE!!
* adding __attribute__((pure)) and __attribute((const)) to help the compiler optimize
* ws.cpp: reduce max "live leds" in fastpath mode
* blurz: some visual improvements
* Matripix: improved color smoothness, Color by frequency (instead of volume), option to use sound pressure
* pixelwave: improved color selection, use sound energy instead of volume
* freqwave: some speedups, option to show frequency with "musical scale"
* gravfreq: fixed some math accidents that lead to horrible flickering
* default setting improved for some effects
* use _fast_ integer types in loops - in contrast to "uint16_t" etc, the compiler can leave out range/overflow corrections, so it might run faster.
* fcn_declare.h: revive "WLED_USE_REAL_MATH" option, which can be a bit faster on ESP32.
*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.
Modifications from upstream have made the effect kind of boring non-reactive. So we go back to the original effect.
HINT: Effect looks best with _segment_ brightness set to max (use _global_ brightness to reduce brightness as you like).
* moving "pbolduc/AsyncTCP.git @ 1.2.0" on top of lib_deps, to prevent that AsyncTCP 1.1.1 is pulled in (due due dependacies from Aircoookie/ESPAsyncWebServer
* remove duplicate env.lib_deps from -S2 environments
* leaving out DotStarHspi5MhzMethod, as we are still on NPB 2.6.9 for eth boards
* leaving out the index.css/index.css changes, as I'm not sure how to merge this.
@ewoudwijma we need to merge the JS and CSS parts when you are back; I'll stay with our MM version for now.
* pio.ini: add "-Wshadow=compatible-local" for V4 targets
* pio.ini: fix alignment for 8266 build_flags
* fix one (harmless) case of shadowed vars in MM specific code
... like the typical -C3
* Replaced a few direct Serial.printf with macros
* Always check if Serial is connected before printing (CDC sometimes hangs when trying to send/receive without connection)
"Unfixing" an optimization to the Art-Net header.
The local "buffer" was shadowing the LED buffer (function parameter), so art-net would only send out headers but no LEDs.
Add ARTI-FX to esp8266_4MB_M (experimental!)
Arti.h
- FREE_SIZE ESP.getFreeHeap() for 8266
- define asChar(x) to print to Serial/File depending on ESP32/8266
- artiPrintf: print to USER_PRINTF (experimental)
Arti_wled.h
- add ARDUINO_ARCH_ESP8266 to ARTI_ARDUINO
- add soundPressure
usermod_v2_artifx.h: use FREE_SIZE
* adjusted gravimeter and waverly effects so that "Sound Pressure" can be used instead of volume
* some improvements to gravimeter effect
* fixing some over/underflows in gravimeter
* waverly: option "No Clouds" to only show lower part
