The DataAcquisition Object

The toolbox interface uses a DataAcquisition object that allows you to communicate easily with devices from National Instruments™, Measurement Computing™, Analog Devices®, Microsoft® Windows® sound cards, and Digilent®. You create a DataAcquisition using the daq function. A DataAcquisition represents one or more channels that you specify on data acquisition devices. You configure a DataAcquisition to acquire or generate data at a specific rate, based on the specified number of scans or the duration of the operation.

For an explanation of how this communication works, see Data Acquisition System. The relationship between you, the application software, the driver software, the chassis, and the devices is shown here.
