Analog input seems to sometime have a very strong negative DC offset, when the signal is not centered at 1.8V. The bandpass filter should help to reenter such "off limits" signals.
See discussions in issue #10 .
const.h: increase SETTINGS_STACK_BUF_SIZE
audio_reactive, 4ld and usermod (xml.cpp)
- add defaults in settings
index.htm: add moon
settings_sec: add WLEDMM about
settings_um: add <br> so comment can be shown decently
platformio:
- remove ABL_MILLIAMPS_DEFAULT from build_flags_min, set default 1500 in const.h
- add default in wemos_shield_esp32_4MB_max_base
- add wemos_shield_esp32_16MB_SPM1423_max
arti_wled.h: bugfix use all leds in 2D
usermod_v2_customeffects.h: fill black if call==0
index.js and xml.cpp: bin name: replace one _ by ' ' to enable line wrap in info tab and ota update
- prepare for merging upstream
--> audiorective files should stay the same after merging!
- makuna just release NeoPixelBus 2.7.1 -> use for "V4" build
* audioreactive driver update
- Better handling of PDM and I2S Line-in
- Bugfixes for ES7243 (allocateMultiplePins)
- More error messages for ES7243
- sample scaling (needed for sources that use full scale of samples)
* audiorective update
* align SR_DEBUG with WLED_DEBUG
* optional bandpass filter (needed for PDM mics)
* sample scaling for PDM and Line-In
* small improvements for analog input
* bugfixes and small performance improvements
* code for FFT task refactored, for better readablity. Introduces separate functions for filtering and post-processing
* small improvement for beat detection
* default mic settings can be configured at compile time
* correct mic type if MCU does not support PDM or ADC
* hide analog PIN config if not supported by MCU
* audioreactive updates
- minor updates to source code (see discussion in PR #2907)
- usermod readme improvements
* small readme update
* one think I overlooked
* ok, another edit. Now its final. Hopefully.
* small upps
wrong parameter order in debug message.
* Grouping um settings, add pre and post Info, update SR & 4LD settings
Settings_um.htm:
- modify addField (grouping)
- addInfo (pre and post texts)
Add preInfo to audio reactive and 4ld usermod
Extra:
platformio: wemos_shield: add audio reactive usermod and update to alt display
* um settings: cpp: lowercase, js: initcap
* um settings: txt only pre, txt2 only post and initCap as function
* Fix rotary encoder info string

- hide "Analog Mic PIN" setting if I2S-ADC is not supported by the hardware
- In case of usupported config (PDM or ADC), overwrite dmType with default.
This introduces an optional band pass filtering step to remove low frequency noise. Very effective for PDM mics - reduces noise floor by a factor of 100 !
