Drivers Manual.

Programming with Device Drivers Function Library

Advantech Device Drivers offer a rich function library that can be uti-

lized in various application programs. This function library consists of

numerous 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.
