./setup.sh

Usage

Plugin LED strip with data on GPIO pin 18

Guide at: https://learn.adafruit.com/neopixels-on-raspberry-pi/raspberry-pi-wiring

To create config file:

cd tools
./gen_config.py new [filename]

If there are secondary controllers

./secondary.py new [foldername]
./put_files.py [sftp_path]

Run

./startup.sh [config_file]

Flask Server (app.py)

• Receives requests to web routes, checks keys, and passes information to multicontroller (multicontroller.py)
• Returns JSON message with strip and error status
• multicontroller.py
  • Forward requests to local or remote controller
• controller.py
  • Calls given function with their arguments
  • Creates virtual strips and passes their information to neopixel class (lights.py)
• lights.py
  • Lights class contains functions that change specific LED colors according to pattern
  • Neopixels class adjusts pixel ids for virtual strips and sends to rpi_ws281x library to change
    physical LED strip
