There are however plans to create a lightweight audioreactive for the 8266, with reduced features. There are however plans to create a lightweight audioreactive for the 8266, with reduced features.
## Installation ## Installation
### using customised _arduinoFFT_ library for use with this usermod ### using latest _arduinoFFT_ library version 2.x
Add `-D USERMOD_AUDIOREACTIVE` to your PlatformIO environment `build_flags`, as well as `https://github.com/blazoncek/arduinoFFT.git` to your `lib_deps`. The latest arduinoFFT release version should be used for audioreactive.
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 * `build_flags` = `-D USERMOD_AUDIOREACTIVE`
* `lib_deps`= `kosme/arduinoFFT @ 2.0.1`
### using latest (develop) _arduinoFFT_ library
Alternatively, you can use the latest arduinoFFT development version.
ArduinoFFT `develop` library is slightly more accurate, and slightly faster than our customised library, however also needs additional 2kB RAM.
* `build_flags` = `-D USERMOD_AUDIOREACTIVE` `-D UM_AUDIOREACTIVE_USE_NEW_FFT`
* `lib_deps`= `https://github.com/kosme/arduinoFFT#develop @ 1.9.2`
