When connected to a Windows, Mac, Linux or Tablet host, it is recognized as a camera. It is possible for the video content to come from a live camera feed, a prerecorded video, or be generated dynamically by using a graphics library such as SEGGER emWin. Using a host as pluggable display does not cost more than the USB connector. No drivers on the host side are required.
The new video class is a component of SEGGER’s emUSB-Device USB stack. emUSB-Device runs on any MCU and is platform-independent. The flexible device stack enables the creation of multi-class devices using nearly any combination of the available USB classes. emUSB-Device provides classes for Media Transfer Protocol, Mass Storage Device, MSD-CDROM, audio, video, Human Interface Device, CDC-ACM (Serial port communication), IP-over-USB, and printers. It also supports a custom communication interface using bulk transfer for easy and fast communication without protocol overhead. emUSB-Device is fully compliant with USB standards.
