How to Build a Drupal RSS Reader on WebScreen for Real-Time News Display
In “Building a Drupal RSS Reader on WebScreen,” HW Lab documents a rapid prototype that repurposes their open-source display device to show Drupal.org news from RSS feeds. Using WebScreen’s fallback animation mode, the developer replaced serial data input with parsed RSS content, retrieved at five-minute intervals and displayed with slow-scrolling text animations.
The implementation included extending the JSON configuration to support RSS, crafting XML parsing logic in C++, and debugging via serial monitor outputs. Real-time logs confirmed when new items—like "Drupal AI Initiative: Co-designing the future"—were displayed or skipped based on timestamp checks.
The setup simulates typical notification behavior: initial ASCII art, a transition animation, followed by two scrolls of each new feed item. The article closes by suggesting possible extensions, including multi-feed support and social media integrations. While creatively executed, the project is early-stage and lacks production polish or broader applicability beyond WebScreen’s niche use.
