Initialization (Data Acquisition Toolbox)

Data Acquisition Toolbox

Initialization

Before a hardware device can carry out a data acquisition task, it must be initialized to a known state. Initialization occurs just after a device object is created.

AI = analoginput('winsound')

After device object creation, the toolbox automatically performs these steps:

The hardware driver is loaded into memory. Vendor-provided calls are used to initialize the hardware to a default state. This default state is typically published by the vendor.
The hardware driver adaptor is loaded into memory.
Hardware-specific properties and their default values are assigned to the device object.

Note:
To initialize a device object, all you need to do is create the device object. The above steps are carried out automatically by the toolbox after device object creation.
