STV0680B + VV6444/6410/6500
Introduction
1.4.6
User features on PC software (STV0680B-003)
All PC software written for a STV0680B-001 camera will function with a STV0680B-003 camera
which is only used to take still images/video.
The SDK (version 2.90 or later) allows for:
q the OEM to write a custom application for uploading sound memos, based on the example
LCDC demo software.
q the OEM to write a custom application for downloading custom sounds to the camera, based
on the example CustomSound software.
1.4.7
Power management features and USB compliance
q Retention of pictures, recorded sounds, and downloaded custom sounds with extremely low
power operation, which appears to the user as if the camera is “switched off”.
q Auto power-off after 30sec with no user activity
q Operates from 4.5-6V battery, although system voltage is 5V or 3.3V, dependant on sensor.
q Low battery detection
q Dependant on hardware configuration, switch-over to USB power supply is supported, to allow
the device to operate with low batteries or without batteries, when connected to USB.
q Full USB compliance requirements are listed in the USB specification, however, in a camera
designed using this chipset, the following must at least be included: (a) an SDRAM with
sufficiently low self-refresh current, (b) USB inrush protection circuitry, and (c) (in the case of
VV6444 only) a switched 5V sensor supply is used, to maintain sufficient supply voltage to the
5V sensor. See Section 4 for further details.
1.4.8
General features
q High speed picture/sounds upload to PC/Mac over USB
q ST Colour processing algorithms included under license (as part of drivers/SDK)
q USB or RS232 serial interface options, and VfW / TWAIN driver support.
