1.5.2 Programming with Device Drivers Function Library

Advantech Device Drivers offers a rich function library to be utilized 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, those APIs can be

categorized into several function groups:

• Digital Input/Output 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.

1.5.3 Troubleshooting Device Driver 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. Or

you can refer to the Device Drivers Error Codes Appendix in the Device

Drivers Manual for a detailed listing of the Error Code, Error ID and the

Error Message.
