Finite Digital Input Programming Flowchart

One way to acquire multiple samples for one or more channels is to acquire single samples in a repetitive manner. However, acquiring a single data sample on one or more channels over and over is inefficient and time consuming. Moreover, you do not have accurate control over the time between each sample or channel. Instead, you can use hardware timing, which uses a buffer in computer memory to acquire data more efficiently. Programmatically, you need to include the timing function, specifying the sample rate and the sample mode (finite). As with other functions, you can acquire multiple samples for a single channel or multiple channels. You can configure a task for measuring digital values using the DAQ Assistant.
