Hardware and Device Drivers

Registering the Hardware Driver Adaptor

When you first create a device object, the associated hardware driver adaptor is automatically registered. The data acquisition engine can now make use of its services.

The hardware driver adaptors included with the toolbox are all located in the daq/private folder. These are the full names for each adaptor.
