Introduction
In addition to the extensive library of standard functions, ADLink provides
an Sample Disk containing a variety of standard applications that you can
use as a starting point for applications development. This manual is a
companion to that disk.
This document is divided into two main sections. The first is a quick
reference that groups the programs into main categories and then lists and
describes the individual programs on the disk that fall into that category.
The second section is a printout of the sample code files. A cross-reference
table of all the files is located at the beginning of this section.
The various application function described here can span a wide variety of
customer applications. Look for examples that may be useful to your
particular motion control application.
The individual files show internals of the features work. Use these examples
as “starter" code to integrate into your development. They will also help you
gain an understanding of how the motion card works and how it implements
the motion functions.
You can also use these functions to debug individual features or function s
and to ensure the motion control subsystem is functioning properly. This
can help isolate problems to specific subsystem level.

Examples
3.1PCI-8134 Initialization
3.1.1 Use 8134.INI to Configure
We provide a very convenient way to modify your configuration from a
Windows® standard INI file. You can edit this file directly by any text editor
or use Config.exe from Appendix C to configure this file.
There are several functions and modules need to be added in your VB
project before programming.
Please check:
(1). PCI-8134 card has been inserted in one PCI slot properly
(2). Make sure that 8134.DLL does exist in your Windows system
directory.
(3). Add two files in your project: Initial.BAS & Def8134.BAS from
Appendix A and B
Note: Initial.BAS provides several functions to deal with 8134.INI
and Def8134.BAS contents all 8134-function library
declarations.

6•Examples
After Add these two files, your project window in VB IDE is like as follows
These two files are very important for 8134 application programming. The
source codes of these two files are listed in appendix A & B
An example of 8134.INI files is as follows:
[Axis 0]
PLS_OUTMODE= 0
PLS_IPTMODE= 0
CNT_SRC= 0
RATIO= 1
HOME_MODE= 0
ORG_LOGIC= 1
ORG_LATCH= 0
EZ_LOGIC= 0
IPT_MODE= 0
OP_MODE= 0
ALM_LOGIC= 0
ALM_MODE= 0
INP_LOGIC= 0
INP_ENABLE= 0
SD_LOGIC= 1
SD_LATCH= 1
SD_ENABLE= 1
ERC_ENABLE= 0
INT_FACTOR= 0
[Axis 1]
PLS_OUTMODE= 0
PLS_IPTMODE= 2

Examples •7
CNT_SRC= 1
RATIO= 2.5
HOME_MODE= 0
ORG_LOGIC= 1
ORG_LATCH= 0
EZ_LOGIC= 1
IPT_MODE= 0
OP_MODE= 0
ALM_LOGIC= 0
ALM_MODE= 0
INP_LOGIC= 0
INP_ENABLE= 0
SD_LOGIC= 1
SD_LATCH= 1
SD_ENABLE= 0
ERC_ENABLE= 0
INT_FACTOR= 8642799

3.1.2 An Example to Load INI file and Configure PCI-8134
Example1: Step by Step
(1). Open a new project.
(2). Add two module files: Def8134.BAS and Initial.BAS
(3). Write Form_Load Procedure
(4). Add the necessary Form variables
(5). Add two text boxes and one command button to show IRQ and base
address
(6). Run it
When we press the show button, it will display IRQ number and Base
address on text box. This form is like as follows:

8•Examples
In Step 3) Form_Load Procedure
Private Sub Form_Load()
' Initialize 8134
If W_8134_Initial(TotalCard, MyPCI) Then
MsgBox "You Don't Have any PCI-8134 Card!"
End
End If
'Load INT file and Configure All Setting
If LoadConfigFile(Axis, TotalCard) Then
MsgBox "You Must Edit an Config File First!"
Else
ConfigAll Axis, TotalCard
End If
End Sub
In Step 4) Add general declaration variables in the Form
Dim TotalCard As Integer
Dim MyPCI As PCI_INFO
Dim Axis(0 To 4*MAX_PCI_CARDS - 1) As AxisConfig
In Step 5) Add some additional objects
Add two text boxes and one button to show IRQ and Base Address
Information.
Object Type Attribute Value
Name Command1
Command Button Caption Show
Name T_IRQ
Text Box Text N/A
Name T_Base
Text Box Text N/A
The codes in Command1 button:
Private Sub Command1_Click()
Dim CardNo,irqNo,baseAddr as integer
CardNo=0
'Show IRQ and Base Address
W_8134_Get_IRQ_Channel CardNo, irqNo
W_8134_Get_Base_Addr CardNo, baseAddr
T_IRQ.Text = Str(irqNo)
T_Base.Text = Hex(baseAddr)
End Sub

Examples •9
After all steps above, run it and you will see the results. If it tells that you
must edit a configuration file first, you should run the config.exe in the
sample disk to create a 8134.INI file.
3.1.3 Programming under Windows NT
There is a little difference when you want to use PCI-8134 library under NT.
The Initializing function parameter is different as follows:
Int i=0;
U16 Total_Card=0;
For(i=0;i<MAX_PCI_CARDS;i++) {
If( W_8134_Initial(i) == 0 )
Total_Card++;
}
You can get the card amounts in Total_Card variable.
Finally, you must close PCI-8134 resourceswhen you exit the program. The
codes are as follows:
int i=0;
for(i=0;i<Total_Card;i++) W_8134_Close(i);
That’s all the differences between Win95 and NT programming
3.2Use Configuration Utility
Sometimes, user needs a configuration interface in his program. We
provide a utility –Config.exe to help user to make it. The config.exe can be
loaded by “Shell” command in user’s program. Use this program to create
or modify 8134.INI and reconfigure PCI-8134 according to this file in user’s
program.

10 •Examples
3.2.1 Config.exe Utility
The config.exe file is at Appendix C and it looks like as follows:
