Programming with DAQNavi Device Drivers Function Library
Advantech offers a comprehensive function library for DAQNavi device drivers that
can be utilized when developing various application programs. This function library
comprises numerous APIs that support many development tools, such as Visual Stu-

These APIs can be categorized into several groups according to their function or pur-
pose.
 Analog Input Function Group
 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, refer to the chapter titled “Using
DAQNavi SDK” in the DAQNavi SDK manual.
Troubleshooting DAQNavi Device Drivers Error
Driver functions return a status code when called to perform a certain task for an
application. When a function returns a code that is not zero, this means the driver has
failed to perform the designated function. To troubleshoot device driver errors, check
the error code and error description in the Error Control section for each function in
the DAQNavi SDK manual.
