Convention nametag that plays videos using a Raspberry Pi W and an SSD1322 panel - Server

Small nametag using Pi Zero W and various OLED panels

Work-in-progress self-programmed convetion nametag using a Raspberry Pi Zero W and a SSD1322 OLED panel. The intended use is pinning it to a shirt or hanging it around your neck and uploading files using your phone.

Current state

• Recycled old gl nametag code
• Proof of concept done:

nametag-poc.mp4

TODO:

• Playlist functionality
• Frontend application / website interface (using React)

OLED Panels

Panels tried during development:

• SH1106 HAT
• SSD1305 HAT
• Soldered SSD1322 using this guide

Frontend

TODO

Backend

• Set up cross-compilation
  • I refer you to crosstool-ng and wish you the best of luck
    • Pick this or this config
• Build with cmake using provided toolchain file

Run with:

• sudo ./nametag (due to GPIO permissions)

Notes:

• Ensure your video is already in desired size
  • From testing, h264 decode for 256x64 in software takes about ~5ms. 480x360 requires about 33ms
  • In combination with 4.5ms copy time, this means <10ms, allowing for up to 100fps
