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
*/
