The SPC_PCIFEATURES register informs you about the options, that are installed on the board. If you want to know about one option being 
installed or not, you need to read out the 32 bit value and mask the interesting bit.

The following example demonstrates how to read out the information about one feature.

This register holds the information of the actual used interrupt line for the board. This information is sometimes more easy in geting the interrupt 
line of one specific board then using the hardware setups of your operating system.

This register holds the information about the driver that is actually used to access the board. Although most users will use the boards within 
a Windows system and most Windows users will use the WDM driver, it can be sometimes necessary of knowing the type of driver.

Driver version
This register informs Windows users about the actual used driver DLL. This information can also be obtained from the device manager. Please 
refer to the „Driver Installation“ chapter. Linux users will get the revision of their kernel driver instead, because linux does not use any DLL.

Kernel Driver version
This register informs OS independent about the actual used kernel driver. Windows users can also get this information from the device ma-
nager. Plese refer to the „Driver Installation“ chapter. Linux users can get the driver version by simply accessing the following register for the 
kernel driver.

SPC_PCIFEATURES

2120

r

PCI feature register. Holds the installed features and options as a bitfield, so the return value must be 
masked with one of the masks below to get information about one certain feature.

PCIBIT_MULTI

1

Is set if the Option Multiple Recording / Multiple Replay is installed.

PCIBIT_DIGITAL

2

Is set if the Option Digital Inputs / Digital Outputs is installed.

PCIBIT_GATE

32

Is set if the Option Gated Sampling / Gated Replay is installed.

PCIBIT_SYNC

512

Is set if the Option Synchronization is installed for that certain board, regardless what kind of synchronization you 
use. Boards without this option cannot be synchronized with other boards.

PCIBIT_TIMESTAMP

1024

Is set if the Option Timestamp is installed.

PCIBIT_STARHUB

2048

Is set on the board, that carrys the starhub piggy-back module. This flag is set in addition to the PCIBIT_SYNC flag 
mentioned above. If on no synchronized board the starhub option is installed, the boards are synchronized with the 
cascading option.

PCIBIT_XIO

8192

Is set if the Option Extra I/O is installed.

SpcGetParam (hDrv, SPC_PCIFEATURES,     &lFeatures);

if (lFeatures & PCIBIT_DIGITAL)
    printf("Option digital inputs is installed on your board");

SPC_PCIINTERRUPT

2300

r

The used interrupt line of the board.

SPC_GETDRVTYPE

1220

r

Gives information about what type of driver is actually used

DRVTYP_DOS

0

DOS driver is used

DRVTYP_LINUX

Linux driver is used

DRVTYP_VXD

2

Windows VXD driver is used (only Windows 95)

DRVTYP_NTLEGACY

3

Windows NT Legacy driver is used (only Windows NT)

DRVTYP_WDM

4

Windows WDM driver is used (only Windows 98/ME/2000/XP). This is the most common Windows driver.

SPC_GETDRVVERSION

1200

r

Gives information about the driver DLL version

SPC_GETKERNELVERSION

1210

r

Gives information about the kernel driver version.
