Driver support available

5.2

Demonstration software

The following is supplied with evaluation kits/demonstration units (This software is mainly for demonstration purposes and should

NOT be supplied as an end-user product.):

1. Simple demonstration software for uploading thumbnails and images.

2. Video demonstration application for STV0680-001 tethered “video” mode through USB (WIN 98 only) (NOT VfW compati-

ble). This is not required for STV0680A, which can be used with standard VfW drivers.

3. AVI creator software for uploading continuous images for creating ‘movie’ clips.

5.3

OEM software

OEM’s have the following options for productisation of a camera based on the chipset:

1. TWAIN driver for uploading images, this would allow the camera to be bundled with standard TWAIN compatible imaging

software.

2. Video for Windows driver for tethered video mode through USB (WIN 98 & WIN2K only). This would allow the camera to be

bundled with standard video for windows software.

3. Development of custom end-user software, including the ST colour process, developed under license using the SDK.

Software Development Kit (SDK)

5.4.1

General

A software development kit is supplied by ST under license agreement, which allows the OEM to develop a custom application

which can perform picture download, thumbnail display, and colour processing. This supports Windows95TM (Serial interface

only) or Windows98/Win2KTM (Serial or USB), and includes features such as:

•

Very fast download (through USB) and colour display of image thumbnails for picture selection

•

Download of full image once selected by user software

•

Colour processing of full image, using the ST colour process

•

Automatic detection and correction of sensor defects

The SDK is supplied by ST as a 32-bit DLL format, running on Windows 98/Win2KTM, and accessed through a documented

software interface. This provides the basis for developing a custom software application for stills and/or video.

The ST SDK for the chipset comprises the following:

•

Interface library containing all Application Programmer’s Interface (API) functions. Provided as C library and header files.

•

All driver files necessary for chosen communications link (supplied as DLL and SYS files).

•

Documentation of all API functions including example code fragments.

All software is built as 32-bit modules for Windows 98/Win2K. The serial communications link is also supported for Windows 95.

A development environment of Microsoft Visual C++ v5 or higher is assumed.

Table 8 : Driver choices

With STV0680, a simple video.exe application is provided. Whilst not being a VfW application, it gives

sufficient framerate to allow for camera test, lens focussing, etc.
