The CERN Display Controller will be the control board for the CERN Display that distributes power and I2C signals to the display boards, and talks WiFi to the network.

Status

  • 2023-05-??: Have been sick for awhile and wanted to design a new thing, so put the schematics/PCB designs/etc. for this together as a quick/simple project.

Design Goals

  • Basic but functional, don't over-complicate things.
  • WiFi to an app that scrapes the various vistars and tells the controller what to display
  • I2C to the display boards via 8p8c connectors

Design Overview

  • ESP32 WiFi/microcontroller
  • PCA9518 I2C buffer to create a star topology I2C network among all the display boards
  • Character LCD and navigation buttons to do basic configuration/troubleshooting

ECOs

  • Rev001
    • TBD!
