Single Sample Digital Output Programming Flowchart
Generating a single sample is an on-demand operation. In other words, NI-DAQmx generates one value on an output channel immediately after the Write function/VI is called. This operation does not require any buffering or hardware timing.
With NI-DAQmx, you also can generate samples from multiple channels. If you prefer, you can configure a task for generating a single sample using the DAQ Assistant.
Tip To increase performance, especially when multiple samples are written, include the Start function/VI and Stop function/VI in your application. In the preceding flowchart, the Start function/VI would come just before you write samples, and Stop would come just before you clear the task. |
