The hardware driver adaptor is the interface between the data acquisition engine and the hardware driver. The adaptor’s main purpose is to pass information between MATLAB® and your hardware device via its driver.
Hardware drivers are provided by the device vendor. For example, to acquire data using a National Instruments® board, the appropriate version of the driver must be installed on your system. Hardware drivers are not installed as part of the toolbox, but a suitable driver is usually installed on PCs that are equipped with a sound card. For any other devices, the drivers must be installed.
