3.1.2 PIO_GetConfigAddressSpace
PIO_GetConfigAddressSpace(wBoardNo,*wBase,*wIrq, *wSubVendor,
• wBoardNo=0 to N
• wBase
• wIrq
• wSubVendor
• wSubDevice
• wSubAux
• wSlotBus
• wSlotDevice
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; /*
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;
}
/* step3: control the OME-PIO-D56/OME-PIO-D24 directly */
wBase=wConfigSpace[0][0];/* get base address the card_0
outport(wBase,1);
wBase=wConfigSpace[1][0];/* get base address the card_1
outport(wBase,1);
