Programming with Device Drivers Function Library
Advantech Device Drivers offer 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 cate-
gorized 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
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. 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.
