Q:Thank you for your e-mail. I appreciate your great effort to help me very much. But,

unfortunately I did not get the answer of my question.

How to determine the I/O port address of the Timer chip (8254) on this "8255-PCI Board"?

A:PCI is a Plug and Play system. It means the address is assigned by the BIOS at 'Power On Self

Test' time. You can not assign the I/O address. The address may change when the system reboots

again. On the other hand, you 'get' the I/O address through BIOS call. In the sample code, it

shows how to get the PCI address. The I/O address of 8254 is the address reported from BIOS

plug 8h. You may download the sample code as follows:(PCI8255-DOS-SAMPLE.ZIP)

Q:Thank you for your e-mail, I appreciated it very much. I understand how to get the (base) port

address of the two 8255 ports (using your utility program) as explained in Chapter-4 of the user

manual.

HARDWARE CONFIGURATION

4.1 I/O Port Address

Base + 0 : Port 1A input/output buffer.

Base + 1 : Port 1B input/output buffer.

Base + 2 : Port 1C input/output buffer.

Base + 3 : Port 1 control register.

Base + 4 : Port 2A input/output buffer.

Base + 5 : Port 2B input/output buffer.

Base + 6 : Port 2C input/output buffer.

Base + 7 : Port 2 control register.

My question, could you used the same program to determine the I/O port addresses of the 8254?

or you have to add codes to determine those addresses?

A:Yes, the I/O address of 8254 is I/O port + (8H to BH).

Q：I'm getting very confused regarding the 8255/8253 card's address. The manual quite clearly states the setting is for either 01B0H or 01F0H dependant on jumper setting. These address don't work. Please tell me which address the board actually sits at, my new customer is getting very annoyed.

A：Please tell us what kinds card do you have?PCI or ISA? If your device is ISA please link our web site to download the ISA8255.zip file.

http://www.pci8255.net/download document.htm

And please tell us what OS do you use? If you use VB to develop and your device is PCI card, you can use diiocx.ocx to design it. Otherwise, please tell us your software environment information.

2002/05/24

Q：I notice that the user's manual does not include any information about the 8254 timer chip that is in the PCI-8255 board. I'd like to receive the following information about the 8254-timer chip:

1- What is the I/O base address of this chip? Or where to get it?

2- Is there any utility programs to test this device? If yes, can you please send it.

3- I need schematics for this device.

A：Please link our web site to download the latest driver for WIN2000/XP.

http://64.177.188.78/PCIIndustrialInterface.exe

The driver will make DecDio.ocx and DecLib.dll two components.

The used method of DecDio.ocx is as same as DiiOcx.ocx so you can reference the dii.pdf page81~99.

http://202.39.29.26/data/io/diipdf.zip

Q：Hello Sir, i am a Manuel Rodighiero friend. You have write to you a mail about the object. I have some question about the DOS OS and APCI8255.

I have set DIP switch :1 On 2 Off 3 Off 4 Off

I have format a floppy disk with a system file and a 2 file 8255set.exe and pci8255.exe and i restart the pc with this floppy.

The result is:

a:\>8255set 0200

New address : 200

and this is correct.

a:\> pci8255

start the test program, option 1, but the result is :

loop : 1 testing pin :0 output : 000001 input: 000002 Correct : 800000

Error

Can you help me , please ?

thanks a lots and goodbye

A：Please connect the loopback when you test the PCI 8255 card.

2002/05/03

Q：We have tried to use th a8255pci card with Dos program ( the one written in basic on the manual) but it does nothing. Have you some usefull suggestions? Have we to set the card address? How? (Now the switch is 1-OFF 2-OFF 3-OFF 4-OFF and we think the correct address would be &H1A0, is TRUE?).

Have you a test program that show me if the card works correctly? (If possible turning on and off the leds?) thank you tery much for your support.

1 other thing......Are you working for driver of Apci8255 under XP with Delphi(6)?

A：We will check the basic program on our manual.

Please use the attached file to set I/O address of PCI 8255 card.

About switch 1, its function is explained as follow:

4.1 I/O Port Address

Base + 0 : Port 1A input/output buffer.

Base + 1 : Port 1B input/output buffer.

Base + 2 : Port 1C input/output buffer.

Base + 3 : Port 1 control register.

Base + 4 : Port 2A input/output buffer.

Base + 5 : Port 2B input/output buffer.

Base + 6 : Port 2C input/output buffer.

Base + 7 : Port 2 control register.

Base + 8 : Counter 0 input/output buffer.

Base + 9 : Counter 1 input/output buffer.

Base + A : Counter 2 input/output buffer.

Base + B : Counter control register.

4.2 DIP Switch

The switch is used to identify card number, default setting is card 1. There are two methods to set the card number:

a. PnP mode

Just plug in PCI bus adapter into PCI slot, the PCI BIOS will allocate I/O address to each adapter automatically and assign card number start from 0 to each adapter. However, if you plug in more than one adapter, please set whole adapters to card number 1 (default setting), then use software tools to distinguish port id.

b. manual mode

Set card number by card identifier switch, the PCI BIOS will assign pre-allocated I/O address to each adapter. Please set different card number to each adapter (do not duplicate card number setting).

The card number starts from 0 to 15.

In additional, please link to our web site to download the PCI 8255 XP driver.

http://64.177.188.78/PCIIndustrialInterface.exe

Please follow below way to install the PCI 8255 card:

Step1. Please uninstall the old driver of the PCI 8255 card.

Step2. Please leave all of PCI 8255 Cards then turn off your PC.

Step3. Please turn on your PC then install the new driver.

Step4. Please turn off the PC then insert all of PCI 8255 cards.

Step5. Please turn on the PC then will install all of PCI 825 cards by auto.

If you want to develop by Delphi, you can use the declib.dll.

Q：we have connected the PCI 8255 Card with an external 1000 Hz clock on
CLK0,CLK1,CLK2.
We use the functions SetConfigTimer and LoadTimer in order to have two
frequencies of 100Hz (ClockRate 10).
We see that the frequencies OUT1 and OUT2 are correct for only few seconds
than the signal always high.
With the function GetTimer we see that when the frequencies goes wrong, the
counter goes to 65535 and begin
to count down.

A：Please don’t use external clock.

Please use the 8254 on the PCI 8255 card when we have modified the new driver.

Please link to our web site to download the latest driver.

Q：Sir, the card don´t suport the DMA access, but, the end of convertion, how can I get it?

A：It is the end of convert when your PC has finished after every loop.

2002/04/26

Q：We have some problems to use the PCI 8255 Card. We are not able to generate a frequency with 8254. Mr Karsten Huster (nt-Ware Germany) gave me the latest version 1.8.12 of software Dii.There is a particular configuration we have to make to generate the frequency? If we try to generate a clock with this code in Visual Basic 6.0 ''

    If (diiDevice.SetTimerConfig(0,&H6)) Then
        If (diiDevice.LoadTimer(0, CInt(tbTimerClockRate.Text))) Then
                lbFailureLoadingTimer.Visible = False
                Exit Sub
        End If
   End If

We check the frequency on the Pin 10 of CN1 Connector (OUT0), we can't see anything Can you give us some suggestings?

A：The problem is from the DII, so we need to modify it.

We will send it as soon as when we have modified it.

2002/04/26

Q：I purchased a PCI 8255 card. I am trying to get my program to communicate with it. I am using DOS as my operating system. I cannot find the card. I have tried the address given in the manual: 0x0300 (300 hex). No luck. All four of the little switches are in the position they were set to when I received the card, that is, all "OFF."

Can you tell me what is the base address of the card with all switches "OFF" ?

A：Please see the attached file it has a setup-test document file and a setup executed file and a test program.

Please follow the setup-test document to setup and test it.

In additionally, the switch S1 is to set card number. Please see below detail information：

DIP Switch

ON 1 2 3 4

The switch is used to identify card number, default setting is card 1. There are two methods to set the card number:

a. PnP mode

b. manual mode

Set card number by card identifier switch, the PCI BIOS will assign pre-allocated I/O address to each adapter. Please set different card number to each adapter (do not duplicate card number setting).

1 2 3 4	Card Number
ON OFF OFF OFF	1
OFF ON OFF OFF	2
ON ON OFF OFF	3
OFF OFF ON OFF	4

The card number starts from 0 to 15.

2002/04/26

Q：We manage to generate the frequency applying an external clock.
With the ISA type card there is the possibility to use
the internal time base clock setting a jumper.
Since on this card has not jumper, is there a software command to
use the internal clock time base?

A：According to our hardware design, it cannot support your demand.

If you want it, we can redesign it to suit your demand.

But it need to pay a little charge.

2002/04/12

Q：I have one more question regarding the I/O base address determination. Aside of the PCI8255.EXE program, how can someone (a programmer) determine the I/O base address of the PCI-8255 Board in DOS environments?

A：Your question didn’t modify the driver when we had researched it.

Please link on our web site to download the source codes.

2002/04/09

Q：I have a couple of questions(If I may) about determining the I/O base address of the PCI 8255/8254. What using your test program (PCI8255.exe), it comes up with.

I/O Address：D800

Is this the I/O base address for this board (i.e. the I/O address for Port A-1)?

If not, how can I determine it? It is true, Port A-2 I/O address = Port A-1 I/O address + 4 ?

A：You are right. That will show the I/O base address when using the test program. Please see the below information about I/O port address:

Base + 0 : Port 1A input/output buffer.

Base + 1 : Port 1B input/output buffer.

Base + 2 : Port 1C input/output buffer.

Base + 3 : Port 1 control register.

Base + 4 : Port 2A input/output buffer.

Base + 5 : Port 2B input/output buffer.

Base + 6 : Port 2C input/output buffer.

Base + 7 : Port 2 control register.

Q： 1- I uses a DOS system.

2- When I run PCI8255.EXE I/O Address :D800 and I/O switch set to 00001

3- When running the "8255 Loopback test" (Test #1) I get:

Loop : 1 Testing Pin: 0 Output: 000001 Input: 0000FE Correct :800000 Error

Loop : 1 Testing Pin: 1 Output: 000002 Input: 0000FE Correct :400000 Error

Loop : 1 Testing Pin: 2 Output: 000004 Input: 0000FE Correct :200000 Error

Loop : 1 Testing Pin: 3 Output: 000008 Input: 0000FE Correct :100000 Error

Loop : 1 Testing Pin: 4 Output: 000010 Input: 0000FE Correct :080000 Error

Loop : 1 Testing Pin:23 Output: 800000 Input: 0000FE Correct :000001 Error

4- In "Output Test" It seems to toggle some of the red LEDs but NOT all ofthem.

5- In "Input test", it seems Bits 0-7 (from the right side of the screen), Bit 15, Bit 24-31 are all stuck high (1)

6- IN "counter Test" none of OUT0 to OUT4 is blinking, rather some I/O ports are blinking.

7- I have swapped the 8255 chip with each other, I got the same results.

My questions are:

1- Do you think this board has gone bad and I should order a new board? Or there is something that I can do to make it to work?

2- Do you have any test program that is written in X86 Assembly language to test this PCI board, that I can use?

3- Do you know where are these red LEDs connected to?

4- Can you send me the schematics of this PCI board?

A：It didn’t have connected the test-loopback about your test result.

Please follow below the picture to test again.

Now we send the attached file to you, it is a manual of PCI 8255.

If you have any question, please do not hesitate to contact us, we do our best to serve you.
