Clean up UserMod settings: grouping of variables and add preInfo to variables (#2894) 
* 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

Audioreactive usermod

This usermod allows controlling LEDs using audio input. Audio input can be either microphone or analog-in (AUX) using appropriate adapter. Supported microphones range from analog (MAX4466, MAX9814, ...) to digital (INMP441, ICS-43434, ...).

The usermod does audio processing and provides data structure that specially written effect can use.

The usermod does not provide effects or draws anything to LED strip/matrix.

Installation

Add -D USERMOD_AUDIOREACTIVE to your PlatformIO environment as well as arduinoFFT to your lib_deps. If you are not using PlatformIO (which you should) try adding #define USERMOD_AUDIOREACTIVE to my_config.h and make sure you have arduinoFFT library downloaded and installed.

Customised arduinoFFT library for use with this usermod can be found at https://github.com/blazoncek/arduinoFFT.git

Configuration

All parameters are runtime configurable though some may require hard boot after change (I2S microphone or selected GPIOs).

If you want to define default GPIOs during compile time use the following (default values in parentheses):

  • DMTYPE=x : defines digital microphone type: 0=analog, 1=generic I2S, 2=ES7243 I2S, 3=SPH0645 I2S, 4=generic I2S with master clock, 5=PDM I2S
  • AUDIOPIN=x : GPIO for analog microphone/AUX-in (36)
  • I2S_SDPIN=x : GPIO for SD pin on digital mcrophone (32)
  • I2S_WSPIN=x : GPIO for WS pin on digital mcrophone (15)
  • I2S_CKPIN=x : GPIO for SCK pin on digital mcrophone (14)
  • ES7243_SDAPIN : GPIO for I2C SDA pin on ES7243 microphone (-1)
  • ES7243_SCLPIN : GPIO for I2C SCL pin on ES7243 microphone (-1)
  • MCLK_PIN=x : GPIO for master clock pin on digital mcrophone (-1)

NOTE Due to the fact that usermod uses I2S peripherial for analog audio sampling, use of analog buttons (i.e. potentiometers) is disabled while running this usermod with analog microphone.
