Adding Interrupt Support

• Depending on the bus type of your board, select a board structure of an

existing board that has the same bus type. The information passed to the

functions is slightly different for an ISA board or a PCI board. You will use

this structure as a template for your own board entry. The following is a

structure for an ISA or PC/104 d evice:

board.name = 'RTD_DM6804';

board.VendorId = -1;

board.DeviceId = 1;

board.SubVendorId = -1;

board.SubDeviceId = -1;

board.PreHookFunction = 'x pc68 04';

board.PostHookFunction = ' NULL ';

board.HookIncludeFile = 'x pc68 04hooks';

board.StartFunction = 'xpc6804start';

board.StopFunction = 'xpc6804stop';

The following is a structure for a PCI device:

board.name = 'General Standards 24DSI 12' ;

board.VendorId = hex2dec('10b5');

board.DeviceId = hex2dec('9080');

board.SubVendorId = hex2dec('10b5');

board.SubDeviceId = hex2dec('3100');

board.PreHookFunction = 'x pcgs 24dsi12prehook';

board.PostHookFunction = ' NULL ';

board.HookIncludeFile = 'x pcgs 24dsi12hooks';

board.StartFunction = 'xpcgs24dsi12start';

board.StopFunction = 'xpcgs24dsi12stop';

• name — Enter an appropriate board name string. The xPC Target

software uses this string to populate the drop-down list for the I/O board

generating the interrupt parame ter in the following:

- Async IRQ Source block

- PCI s lot (-1: autosearch) or ISA base address parameter in the

xPC Target Options section of the model Con figuration Parameters

dialog box

•

VendorId, DeviceId, SubVendorId, SubDeviceId — Enter the appropriate

ID strings. If you have a PCI board, the board manufacturer identifies

5-11
