3.1.2 PIO_GetConfigAddressSpace

PIO_GetConfigAddressSpace(wBoardNo,*wBase,*wIrq, *wSubVendor,

*wSubDevice,*wSubAux,*wSlotBus, *wSlotDevice)

• wBoardNo=0 to N Æ totally N+1 boards found by PIO_DriveInit(….)

• wBase Æ base address of the board control word

• wIrq Æ allocated IRQ channel number of this board

• wSubVendor Æ subVendor ID of this board

• wSubDevice Æ subDevice ID of this board

• wSubAux Æ subAux ID of this board

• wSlotBus Æ hardware slot ID1 of this board

• wSlotDevice Æ hardware slot ID2 of this board

The user can use this function to save resource of all OME-PIO/PISO cards

installed in this system. Then the application program can control all functions of

OME-PIO/PISO series card directly. The sample program is given as follows:

/* step1: detect all OME-PIO-D56/OME-PIO-D24 cards first */

wSubVendor=0x80; wSubDevice=1; wSubAux=0x40; /* for OME-PIO-

D56/D24 */

wRetVal=PIO_DriverInit(&wBoards, wSubVendor,wSubDevice,wSubAux);

printf("There are %d OME-PIO-D56/OME-PIO-D24 Cards in this PC\n",wBoards);

/* step2: save resource of all OME-PIO-D56/OME-PIO-D24 cards installed in this

PC */

for (i=0; i<wBoards; i++)

{

PIO_GetConfigAddressSpace(i,&wBase,&wIrq,&t1,&t2,&t3,&t4,&t5);

printf("\nCard_%d: wBase=%x, wIrq=%x", i,wBase,wIrq);

wConfigSpace[i][0]=wBaseAddress; /* save all resource of this card */

wConfigSpace[i][1]=wIrq; /* save all resource of this card */

}

/* step3: control the OME-PIO-D56/OME-PIO-D24 directly */

wBase=wConfigSpace[0][0];/* get base address the card_0 */

outport(wBase,1); /* enable all D/I/O operations of card_0 */

wBase=wConfigSpace[1][0];/* get base address the card_1 */

outport(wBase,1); /* enable all D/I/O operations of card_1 */
