# tinyscreen: reconstructing an ArtInChip USB display protocol

> tinyscreen implements a Linux client for ArtInChip USB bar displays using a reconstructed device protocol. It performs the display's two-phase RSA challenge-response exchange and sends JPEG frames with 20-byte headers over USB bulk transfers. The client can present dashboards, video, web pages or an EVDI virtual monitor.
