1.5 Device Driver Programming

This section will provide a roadmap to demonstrate how to build an appli- cation from scratch using the Device Drivers with your favorite development tools such as Visual C++, Visual Basic. The step-by-step instructions on how to build your own applications using each development tool will be given in the Device Drivers Manual. Moreover, a rich set of example source code is also given for your reference.

1.5.1 Programming Tools

Programmers can develop application programs with the following devel- opment tools:

•Visual C++

•Visual Basic

For instructions on how to begin programming in each development tool, a Tutorial Chapter in the Device Drivers Manual is included for your reference. Please refer to the corresponding sections in this chapter on the Device Drivers Manual to begin your programming efforts. You can also look at the example source code provided for each programming tool, since they can get you very well oriented.

The Device Drivers Manual can be found on the companion CD-ROM. Alternatively, if you have already installed the Device Drivers on your system, The Device Drivers Manual can be readily accessed through the Start button:

Start/Programs/Omega USB-4700 Series/Device Driver’s Manual

The example source code can be found under the corresponding installa- tion folder such as the default installation path:

C:/Program Files/Omega/USB-4700/Examples

For information about using other function groups or other development tools, please refer to Creating Windows 2000/XP Applications with Device Drivers chapter and the Function Overview chapter in the Device Drivers Manual.
