I/O Driver Block Library

You can open the I/O device driver library with the MATLAB command xpclib. The library xpclib contains sublibraries grouped by the type of I/O function they provide.

When you double-click one of these groups, the sublibrary opens displaying a list grouped by manufacturer as shown below.

Double-clicking one of the manufacturer groups then displays the set of I/O device driver blocks for the specified I/O functionality (for example, A/D, D/A, Digital Inputs, Digital Outputs, and so on).

The following figure shows the A/D drivers for the manufacturer ComputerBoards, Inc.

When you double-click one of these blocks, a Block Parameters dialog box opens allowing you to make hardware-specific parameters. Parameters typically include:

• Sample time
• Number of channels
• Voltage range
• Base address (ISA boards)
