STV0674 Application Examples
The initial STV0674 released by ST Microelectronics is supplied with generic firmware application
code to realise one of the following camera types.
Webcam with audio
Overview
This camera uses the minimum of external components and has no user interface, batteries or
memory for image storage. It is used as a tethered video capture camera over USB, with
simultaneous audio and video. It is controlled entirely through PC drivers. The application specific
firmware is downloaded from the PC.
A custom USB PID/VID can be configured by the use of an EEPROM, if required.
