Slideshow for RaspberryPi

Start a slideshow in fullscreen Chromium on startup for Raspberry Pi

Required

• RaspberryPi with Raspbian Jessie
• NodeJS with ES6 (v6+)
• Node forever: sudo npm -g install forever
• USB library: sudo apt-get install build-essential libudev-dev

Install

• npm install

Config

• volumesDir - Directory where USB disks are mounted (default /media/pi/)
• imagesDirName - Images directory name
• slideshowInterval - Time in ms for each image to be shown
• slideshowTransition - Time in ms for transition between images

How it works

• When app is started it looks for image folder on USB disks (<volumesDir>/**/<imageDirName>)
  • If no image dir is found it will use the default image folder ./images
• Server is started with hosting images from found image folder
• Config can be overwritten by creating a SETTINGS.txt file in images folder
  • Settings file must be formatted in INI style: lideshowInterval=N
• When a USB stick is attached the app will restart and the slideshow will be refreshed with the new images folder

Get it running
