Using the Device Control VIs (Blackfin, Embedded Module)

The Embedded Module for Blackfin Processors contains a common BF Device Control VI you can use for each different driver. Use the BF Device Control VI to configure, enable, and disable data flow through a Blackfin device. Most device drivers initialize with some default settings when you open the driver. If those settings are not appropriate for the application, each device driver also contains a driver-specific control VI so you can set and detect device-specific configurations.

To specify device-specific configuration parameters, right-click the command input input and select Create»Constant from the shortcut menu. The constant you create is a cluster array where each cluster element is a pair of values. The first value is an enumerated list of all possible commands for the specified device. The second value specifies the value for the command you select. The command input constant is an array so you can configure multiple commands simultaneously. In some cases, the command value is an enumeration, which means you must use the integer value associated with the enumeration instead of the enumeration text.
