SEGGER adds video to emUSB-device

SEGGER introduces video class (UVC) support for emUSB-Device. An Embedded System with a USB device interface can now enumerate as a video camera. Once connected to a Host (Windows, Mac, Linux or Tablet), it is recognized as a camera. Video content can come from a live camera feed, a prerecorded video, or can be generated dynamically by using a graphics library such as SEGGER emWin. The ability to use a host as pluggable display does not cost more than the USB connector. No drivers on the host side are required.

Typical application examples include digital still cameras, video cameras, webcams, and all other devices that play instructional videos or provide animated video content. It can also be used for “headless” devices, that do not have their own display. There are primarily 2 types of applications: systems which only rarely need a display, such as engines or solar inverters, and systems with separate display units, such as washing machines, where the main processor controls the machine and is connected to a host showing the video on a display.

The video class is a component of SEGGER’s high performance USB stack emUSB-Device. emUSB-Device is specifically designed for Embedded Systems. It runs on any microcontroller 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. The emUSB-Device is fully compliant with USB standards.
