1.5 Device Driver Programming Roadmap

This section will provide you a roadmap to demonstrate how to build an
application from scratch using Advantech Device Drivers with your
favorite development tools such as Visual C++, Visual Basic, Delphi and
C++ Builder. 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.

Programming Tools

Programmers can develop application programs with their favorite devel-
opment tools:
•  Visual C++
•  Visual Basic
• Delphi
•  C++ Builder
For instructions on how to begin programming works in each develop-
ment tool, Advantech offers a

Tutorial

Chapter in the

Device Drivers

Manual

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/Advantech Automation/Device Manager/Device Driver's
Manual
The example source code can be found under the corresponding installa-
tion folder such as the default installation path:
