Spectrum analyzer for RaspberryPi that lets you use LPD8806 or WS2801 LED chipset, and also takes input either from a local file or via airplay/line-in.
This project started by following a guide on Adafruit. After encountering some issues getting the code to work with our hardware, we refactored into this repository.
To get the hardware setup (i.e. - configure Raspberry Pi, wire up LEDs, tune SPI) the guide referenced above is a good starting point. Once you verify that the LEDs are functional, you can clone this repository into a new directory then follow instructions below to install and run.
Run the install shell script using
bash install.sh
This will create a python virtual environment for you at BUILD/venv. Source this virtualenv for all future work, on this project.
source BUILD/venv/bin/activate
run.py is the main entry point. python run.py will give you usage information.
You can use a local file as input, as follows:
python run.py local /path/to/file.mp3
To use airplay, run:
python run.py airplay
To use line input, run:
python run.py linein
