3.1.1PIO_DriverInit

PIO_DriverInit(&wBoards, wSubVendor,wSubDevice,wSubAux)

•wBoards=0 to N Æ number of boards found in this PC

•wSubVendor Æ subVendor ID of board to find

•	wSubDevice	Æ subDevice ID of board to find
•	wSubAux	Æ subAux ID of board to find
	This function	can detect all OME-PIO/PISO series card in the system. It is

implemented based on the PCI plug & play mechanism. It will find all OME- PIO/PISO series cards installed in this system & save all their resources in the library.

Sample program 1: find all OME-PIO-D96 installed in the PC

wSubVendor=0x80; wSubDevice=1; wSubAux=0x10; /* for PIO_D96 */

wRetVal=PIO_DriverInit(&wBoards, wSubVendor,wSubDevice,wSubAux); printf("Threr are %d OME-PIO-D96 Cards in this PC\n",wBoards);

/* step2: save resource of all OME-PIO-D96cards installed in this PC */
for (i=0; i<wBoards; i++)
{
PIO_GetConfigAddressSpace(i,&wBase,&wIrq,&wID1,&wID2,&wID3,
&wID4,&wID5);
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	*/
}

Sample program 2: find all OME-PIO/PISO installed in the PC (refer to Sec. 4.1 for more information)

wRetVal=PIO_DriverInit(&wBoards,0xff,0xff,0xff);	/*find all PIO_PISO*/
printf("\nThrer are %d PIO_PISO Cards in this PC",wBoards);
if (wBoards==0-----------------------------------------------------) exit(0);	");
printf("\n

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

{

PIO_GetConfigAddressSpace(i,&wBase,&wIrq,&wSubVendor, &wSubDevice,&wSubAux,&wSlotBus,&wSlotDevice);

printf("\nCard_%d:wBase=%x,wIrq=%x,subID=[%x,%x,%x], SlotID=[%x,%x]",i,wBase,wIrq,wSubVendor,wSubDevice, wSubAux,wSlotBus,wSlotDevice);

printf(" --> "); ShowPioPiso(wSubVendor,wSubDevice,wSubAux);

}
