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 resources 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 source is given as follows:
/* step1: detect all OME-PIO-D96 cards first */
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-D96 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-D96 directly */
wBase=wConfigSpace[0][0];/* get base address the card_0 */
outport(wBase,1); /* enable all D/I/O operation of card_0 */
wBase=wConfigSpace[1][0];/* get base address the card_1 */
outport(wBase,1); /* enable all D/I/O operation of card_1 */
