5getxpcpci

Purpose Determine which PCI boards are installed in the target PC

Syntax MATLAB Command Line

getxpcpci(’type_of_boards’)

Arguments

Description The information is displayed in the MATLAB window. Only devices supported

by driver blocks in the xPC Target Block Library are displayed. The

information includes the PCI bus number, slot number, assigned IRQ number,

manufacturer name, board name, device type, manufacturer PCI Id, and the

board PCI Id itself.

For a successful query:

• The host-target communication link must be working. (The function

xpctargetping must return success before using the function getxpcpci.

• Either a target application is loaded or the loader is active. The latter is used

to query for resources assigned to a specific PCI device, which have to be

provided to a driver block dialog box prior to the model build process.

Examples Return the result of the query in the struct pcidevs instead of displaying it.

The struct

pcidevs is an array with one element for each detected PCI device.

Each element combines the information by a set of fieldnames. The struct

contains more information compared to the displayed list, such as the assigned

base addresses, the base and sub class.

pcidevs = getxpcpci

Display the supported and installed PCI devices.

getxpcpci(’all’)

Display the installed PCI devices, not only the devices supported by the xPC

Target Block Library. This will include graphics controller, network cards,

SCSI cards and even devices which are part of the motherboard chipset (for

example PCI-to-PCI bridges).

getxpcpci(’all’)

type_of_boards Values are no arguments, ’all’ and ’supported’.
