The CERN Display Controller will be the control board for the CERN Mimic Panel that distributes power and I2C signals to the display boards, and talks WiFi to the network.
Contents
Status
- 2023-05-10: Completed PCB layout and checklisting, need to do the 24h pause and re-check still. Will probably wait to send this design out until I have a display board with it.
- 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!
