Bloko's ticker scroller display

  • This software was developed for my friend Ignacio Gatica's art project called "Stones Above Diamonds"
  • It's job is to control an LED display, similar to the ones seen on financial districts. Here is a picture of it in action at Hessel Museum of Art: Stones Above Diamonds by Ignacio Gatica

Install

  • This software is meant to run on a Raspberry Pi running Raspberry Pi OS. Tested on Raspberry Pi OS Lite Kernel version: 5.10, Debian version: 11 (bullseye)
  • Requires Python version 3.7 at least, tested on 3.9
  • Requires internet connection in order to update ticker values
  • For the ticker display:
    • You must first install this: https://github.com/hzeller/rpi-rgb-led-matrix
    • Make sure Python 3 bindings are correctly installed by running some samples
    • Then clone this repo inside bindings/python/samples folder
    • Only then you should try to run the ticker

Autostart setup

  • Run ./install-services.sh
  • Make sure its executable chmod +x install-services.sh

Handy commands
