Programming with Device Drivers Function Library

Advantech Device Drivers offer a rich function library that can be utilized

in various application programs. This function library consists of numer-

ous APIs that support many development tools, such as Visual C++,

Visual Basic, Delphi and C++ Builder.

According to their specific functions or services, the APIs can be catego-

rized into several function groups:

• Analog Output Function Group

• Digital Input/Output Function Group

• Counter Function Group

• Port Function Group (direct I/O)

• Event Function Group

For the usage and parameters of each function, please refer to the Func-

tion Overview chapter in the Device Drivers Manual.

Troubleshooting Device Drivers Error

Driver functions will return a status code when they are called to perform

a certain task for the application. When a function returns a code that is

not zero, it means the function has failed to perform its designated func-

tion. To troubleshoot the Device Drivers error, you can pass the error

code to DRV_GetErrorMessage function to return the error message.

Alternatively, you can refer to the Device Drivers Error Codes Appendix

in the Device Drivers Manual for a detailed listing of Error Codes, Error

IDs and the Error Messages.

1.6 Accessories

Advantech offers a complete set of accessory products to support the PCI-

1723 card. These accessories include:

Wiring Cable PCL-10168

The PCL-10168 shielded cable is specially designed for PCI-1723 cards

to provide high resistance to noise. To achieve a better signal quality, the

signal wires are twisted in such a way as to form a “twisted-pair cable,”

reducing cross talk and noise from other signal sources. Furthermore, its

analog and digital lines are separately sheathed and shielded to neutralize

EMI/EMC problems.
