to every OME-PISO series card. The fixed IDs of OME-PISO series card are given as

follows:

• Vendor ID = 0xE159

• Device ID = 0x0002

The sub IDs of OME-PISO-813 are given as follows:

• Sub-vendor ID = 0x80

• Sub-device ID = 0x0A

• Sub-aux ID = 0x00

The following software functions are provided:

1. PIO_DriverInit(&wBoard, wSubVendor, wSubDevice, wSubAux)

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

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

All functions are defined in PIO.H. Refer to Chapter 4 for further details. The function

parameters are described below

1. Resource information:

• wBase : BASE I/O address of the card

• wIrq: IRQ channel number allocated

2. OME-PISO identification information:

• wSubVendor: subVendor ID of this board

• wSubDevice: subDevice ID of this board

• wSubAux: subAux ID of this board

3. PC’s physical slot information:

• wSlotBus: hardware slot ID1

• wSlotDevice: hardware slot ID2

The utility program, OME-PIO_PISO.EXE, will detect & show all OME-PISO cards

installed in this PC. Refer to Sec. 4.1 for more information.

13

2.1.1 PIO_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-1. It will find all OME-

PIO/PISO series cards installed in this system and save their resource in the library.

Sample program 1: find all OME-PISO-813 in this PC

wSubVendor=0x80; wSubDevice=0xa; wSubAux=0x00;/* for OME-PISO-813 */

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

printf("There are %d OME-PISO-813 Cards in this PC\n",wBoards);

/* step2: save resource of all OME-PISO-813 cards 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 in this PC(refer to Sec. 4.1 for more

information)

wRetVal=PIO_DriverInit(&wBoards,0xff,0xff,0xff); /*find all OME-PIO_PISO*/

printf("\nThrer are %d OME-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);

/* step1: detect all OME-PISO-813 cards */

wSubVendor=0x80; wSubDevice=0xa; wSubAux=0x0; /* for OME-PISO-813 */

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

printf("There are %d OME-PISO-813 Cards in this PC\n",wBoards);

/* step2: save the resources of all OME-PISO-813 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-PISO-813 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*/

17

• 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 will show a text string for the subIDs. This text string is the same as that

defined in PIO.H

Sample code is shown below:

wRetVal=PIO_DriverInit(&wBoards,0xff,0xff,0xff); /*find all OME-PIO_PISO*/

printf("\nThrer are %d OME-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);
}

18

2.2 The Assignment of I/O Address

The plug & play BIOS will assign a valid I/O address to OME-PIO/PISO series

card. If there is only one OME-PIO/PISO board, the user can identify the board as

card_0. If there are two OME-PIO/PISO boards in the system, it is more difficult to

identify which board is card_0? The software driver can support up to16 boards in a

computer.

The simplest way to identify which card is card_0 is to use wSlotBus &

wSlotDevice as follows:

1. Remove all OME-PISO-813 cards from the PC

2. Install one OME-PISO-813 into the PC’s PCI_slot1,

run OME-PIO_PISO.EXE & record the wSlotBus1 & wSlotDevice1

3. Remove all OME-PISO-813 from the PC

4. Install one OME-PISO-813 into the PC’s PCI_slot2,

run OME-PIO_PISO.EXE & record the wSlotBus2 & wSlotDevice2

5. repeat (3) & (4) for all PCI_slots, record all wSlotBus & wSlotDevice

The recorded information may appear as follows:

PC’s PCI slot WslotBus wSlotDevice
Slot_1 0 0x07
Slot_2 0 0x08
Slot_3 0 0x09
Slot_4 0 0x0A
PCI-BRIDGE
Slot_5 1 0x0A
Slot_6 1 0x08
Slot_7 1 0x09
Slot_8 1 0x07

These values will be mapped to this PC’s physical slot. This mapping will not change

for any OME-PIO/PISO cards. This can be used to identify the specific OME-

PIO/PISO card. The procedure is as follows:

Step1: Record all wSlotBus? and wSlotDevice

Step2: Use PIO_GetConfigAddressSpace(…) to get the specific card’s wSlotBus &

wSlotDevice

Step3: The user can identify the specific OME-PIO/PISO card if he compares the

wSlotBus and wSlotDevice of step2 to step1.

19

2.3 The I/O Address Map

The I/O address of OME-PIO/PISO series cards is automatically assigned

by the motherboard ROM BIOS. The I/O address can also be re-assigned by

user. It is strongly recommended that the user not change the BIOS

assigned I/O address. This could result in system problems if an invalid

address is used.

The I/O address map of OME-PISO-813 is shown below:

all D/I/O operations. The user has to set the RESET\ signal to High-state before any

D/I/O command.

3. Demo Programs

The OME-PISO-813 includes a comprehensive set of drivers and demonstration

programs for programming under various operating systems and programming

platforms. During the software installation process, the following screen allows the

user to install the appropriate files for a specific installation.

Please read the release notes for the most up to date information regarding the
OME-PISO-813 hardware and software.

The first step for most OME-PISO-813 programs is to identify the cards in the
computer system and determine the resources allocated to those cards. The
PIO_PISO.EXE program performs that function. The source code for the
PIO_PISO.EXE program is shown below.

3.1 PIO_PISO.EXE Program

/* ------------------------------------------------------------ */
/* Find all OME-PIO_PISO series cards in this PC system */
/* step 1: plug all OME-PIO_PISO cards into PC */
/* step 2: run PIO_PISO.EXE */
/* ------------------------------------------------------------ */

#include "PIO.H"

WORD wBase,wIrq;
WORD wBase2,wIrq2;

int main()
{
int i,j,j1,j2,j3,j4,k,jj,dd,j11,j22,j33,j44;
WORD wBoards,wRetVal;
WORD wSubVendor,wSubDevice,wSubAux,wSlotBus,wSlotDevice;
char c;
float ok,err;

clrscr();
wRetVal=PIO_DriverInit(&wBoards,0xff,0xff,0xff); /*for PIO-PISO */
printf("\nThere are %d OME-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);
}

PIO_DriverClose();
}

NOTE: PIO_PISO.EXE is valid for all OME-PIO/PISO cards. It can be found in the
DIAG directory. Running PIO_PISO.EXE will provide the following information:

• List all OME-PIO/PISO cards installed in this PC

• List all resources allocated to every OME-PIO/PISO cards

• List the wSlotBus & wSlotDevice for specified OME-PIO/PISO card identification.

(Refer to Sec. 3.2 for more information)

Although most users will use the functions in the software driver to program the PISO-

813, DEMO1.C demonstrates how to measure 32 analog inputs by programming

directly to the registers on the board.
