Prerequisits:

Up and running installation of Piano-LED-Visualizer.

Installation:

1. Create a backup:

This addon is without warranty! I strongly recommend making a backup of your existing installation beforehand. Generally, I recommend installing on a new SD card with the latest release of "Raspbian 12 (bookworm)" as minimal OS, as well as the latest version of Piano-LED-Visualizer and rtpMIDI Daemon.

2. Update your system!:

sudo apt-get update
sudo apt-get upgrade

*it will take a while, go grab a coffee

3. Copy php directory to your existing installation

Navigate to the webinterface folder of your PLV installation

cd /home/Piano-LED-Visualizer/webinterface

• GIT clone repository

sudo git clone https://github.com/geg1965/Piano-LED-Visualizer-Addon php

4. Installing php:

sudo apt-get install php8.2-common php8.2-cli

Thanks to onlaj for his work on the Piano-LED-Visualizer! I really enjoyed creating this interactive lighting for my master keyboard. The ledemu2.html used here is part of his code and has only been minimally adapted (autorefresh added).
