Digital Output Programming Flowcharts
This section contains general programming flowcharts that you can use when creating an application. You also can find programming flowcharts for typical applications in the Common Applications section of this help file.
In the programming flowcharts, many applications also include explicit control functions to start, stop, and clear the task. For instance, for applications that use your counter/timer, such as counting edges or measuring period, you need to call the Start function/VI to arm the counter. In LabVIEW, clearing occurs automatically. For other ADEs, you must include these functions in your application.
Functions and VIs provide the core functionality of the NI-DAQmx API. For instance, NI-DAQmx includes functions for timing, triggering, reading, and writing samples. However, for advanced functionality, Visual C++, Visual C#, Visual Basic .NET, and LabVIEW require properties. ANSI C and LabWindows/CVI employ the Get and Set Attribute functions. For more information, refer to the programming reference help for your ADE.
