1. Introduction
LinPAC-5000 is the new generation Linux-based PAC from ICP DAS and is equipped
with a PXA270 CPU (520 MHz) running a Linux kernel 2.6.19 operating system, variant
connectivity (VGA, USB, Ethernet, RS-232/485 and audio port) and contains an optional I/O
expansion board that can be used for implementing various I/O functions, such as D/I, D/O,
A/D, D/A, Timer/Counter, UART, flash memory, etc.
The LP-5000 had the advantages of good control system. These advantages include:
stability, small core size, I/O expansion board optional, support for Web services
(Web/FTP/Telnet/SSH server), support
for multiple development environments (LinPAC
SDK for Linux and Windows environment using the GNU C language, JAVA, GUI software),
etc. They give you all of the best features of both traditional PLCs and Linux capable PCs.
That’s the most powerful and flexible embedded control system.
Compared to the first generation LinCon-8000, it not only improves the CPU
performance (from 206 MHz to 520 MHz) and upgraded OS (from Linux kernel 2.4 to Linux
kernel 2.6), but also adds many reliability features, such as plam-sized, dual LAN, audio
ports, I/O expansion board optional, etc. That’s the most powerful control systems available.
LinPAC-5000 SDK Manual:5
ICP DAS provides the library file - libi8k.a which includes all the functions from the
I-7000/8000/87000 series modules which are used in the LinPAC-5000 Embedded
Controller. The libi8k.a is designed specially for the high profile I-7000/8000/87000 series
modules on the Linux platform for use in the LinPAC-5000. Users can easily develop
applications in the LinPAC-5000 by using either C or Java Language and the .NET
applications will also be supported in the future. The various functions of the libi8k.a are
divided into the sub-group functions for ease of use within the different applications. The
powerful functions of the LinPAC-5000 embedded controller are depicted in figure 1-1, which
includes a VGA, USB (Card Reader, Camera …), Mouse, Keyboard, microSD card,
Series ports (RS-232/485), Ethernet (Hub…), etc. in the picture. Presently, HTTP, FTP,
Telnet, SSH and SFTP Servers are built in and users can transfer files or use remote control
with the LinPAC-5000 more conveniently. In network communication, wireless, Bluetooth
transfer and Modem, GPRS, ADSL and Firewall are also supported. Fig. 1 illustrates
hardware architecture of the LinPAC-5000.

2.2 The LinPAC-5000 SDK Introduction
In this section, we will discuss some techniques that are adopted in the LinPAC-5000.
Through our detailed explanations, users can learn how to use the LinPAC-5000 easily.
LinPAC-5000 SDK is based on cygwin and it is also a Linux-like environment for Windows. It
still provides a powerful GCC cross-compiler and an IDE (Integrated Development
Environment) for developing LinPAC-5000 applications quickly. Therefore after you have
written your applications, you can compile them through the LinPAC-5000 SDK into
executable files that can be run in your LinPAC-5000 embedded controller.
LinPAC-5000 SDK Manual:9
2.2.1 Introduction to Cygwin
What is Cygwn ? Cygwin is a collection of free software tools originally developed by
Cygnus Solutions to allow various versions of Microsoft Windows to act somewhat like a
UNIX system. That is Cygwin is a Linux-like environment for Windows. It consists of two
parts:
(1) A DLL (cygwin1.dll) which acts as a Linux emulation layer providing substantial Linux API
functionality.
(2) A collection of tools, which provide users with the Linux look and feel.
2.2.2 Introduction to Cross-Compilation
What is Cross-Compilation? Generally, compiling a program takes place by running the
compiler on the build platform. The compiled program will run on the target platform. Usually
these two processes are on the same platform; if they are different, the process is called
cross-compilation. That is the process that can compile source code on one platform to the
executable files on other platforms. For example, you can compile source code in a x86
windows platform into an executable file that can run on an arm-linux platform if you use the
cross-compiler - “arm-linux-gcc”.
So why do we use Cross-Compilation? In fact, Cross-Compilation is sometimes more
involved and errors are easier to make than with normal compilation. Therefore it is often
only employed if the target is not able to compile programs on its own or when we want to
compile large programs that need more resources than the target can provide. For many
embedded systems, cross-compilation is the only possible way.
2.2.3 Download the LinPAC-5000 SDK

LinPAC-5000 SDK Manual:10
3.The Architecture of library in the LinPAC-5000
The libi8k.a and libxboard.a are both a library file. The libi8k.a is designed for
I7000/8000/87000 applications and libxboard.a is designed for I/O expansion boards.
There are running in the LinPAC-5000 Embedded Controller using the Linux OS. Users can
apply it to develop their own applications with GNU C language. In order to assist users to
build their project quickly, we provide many demo programs. Based on these demo
programs, users can easily understand how to use these functions and develop their own
applications within a short period of time.
The relationships among the libi8k.a and user’s applications are depicted as Fig. 3-1:

4. LinPAC-5000 System Settings
In this section, we will introduce how to setup the LinPAC-5000 configuration. Let users
can use the LinPAC-5000 more easily.
4.1 Settings for the LinPAC-5000 Network
The LinPAC-5000 network setting includes two ways. One is DHCP and the other is
“Assigned IP”. DHCP is the default setting after the LinPAC-5000 is produced and this way
is easy for users. However, if your network system is without DHCP server, then users need
to configure the network setting by using “Assigned IP”.
4.1.1 Setting the IP、Netmask and Gateway
(1) Using DHCP :
Boot up LinPAC-5000 and click the “start/xterm” to open a “command Prompt”.
Type in “vi /etc/network/interfaces” to open the network setting file. Remove “#” in
the dhcp block and add “#” in the Assign IP block. Then type “:wq” to save the
setting. Type “ifup eth0” to make the setting work. (Refer to the Fig 4-1)
Fig 4-1
LinPAC-5000 SDK Manual:13
(2) Using “Assigned IP” :
Boot up LinPAC-5000 and click the “ start/xterm ” to open a “command line”.
Type in “ vi /etc/network/interfaces ” to open the network setting file. Remove “ # ”
in the Assign IP block and add “ # ” in the dhcp block. Type ip、netmask and gateway
you want in the Assign IP block. Then type “ :wq ” to save the setting. Type “ ifup
eth0 “ to make the setting work. (Refer to the Fig 4-2)
Fig 4-2
After finish the LinPAC network setting, users can type “ ifconfig “ to see the network
setting. (Refer to the Fig 4-3)

LinPAC-5000 SDK Manual:16
4.3 USB Storage Device Usage
Users need to mount the USB storage device to the LinPAC-5000, before they can
access the USB storage device. This is because it will not auto-mount the USB storage
device in the LinPAC-5000
4.3.1 Mount USB Storage Device
The steps are as follows :
(1) Type “ mkdir
/mnt/usb “ to build a usb directory.
(2) Type “mount
/dev/sda1
directory and type “ ls
/mnt/usb“ to mount the USB storage device to the usb
/mnt/usb ” to see the content of USB storage device.
4.3.2 Umount USB Storage Device

type the “ umount
/mnt/usb “ command first. Then pull out the USB storage device to
prevent any damage to usb storage device.
4.4 Adjust VGA Resolution
There are two modes -- 640x480、800x600 supported in the LinPAC VGA resolution and
the default setting is 800x600. If users want to change the VGA resolution. Please follow
below steps :
(1) Type “ vi /etc/init.d/fbman “ to open resolution setting file.
(2) If users want to set the resolution to be 640x480. First, add “ # ” in the 800x600
column and then remove “ # ” in the 640x480 column. Type “ :wq “ to save the
setting. (Refer to Fig 4-6)
(3) Type “ reboot “ to reboot LinPAC-5000.
Note: This function can not support LinPAC-53x1.
LinPAC-5000 SDK Manual:17
Fig 4-6
4.5 Running applications automatically at boot time
A “run level” determines which programs are executed at system startup. Run level 2 is
the default run level of LinPAC-5000.
The contents of run level are in the /etc/init.d directory that directory contains the scripts
executed at boot time. These scripts are referenced by symbolic links in the /etc/rc2.d.
These links are named S<2-digit-number><original-name>. The numbers determine the
order in which the scripts are run, from 00 to 99 — the lower number would earlier executed.
Scripts named with an S are called with start, and named with a K or x are called with stop.
4.5.1 Making program run at boot time
Making program run at boot time, you should create a startup script placed in /etc/init.d
directory that runs the required commands for executed automatically at boot time and be
symbolically linked to /etc/rc2.d directory.
The steps are as follows :
(1) Type “ vi
/etc/init.d/hello “ to edit a script that would like to executed program,
filename is hello. Type “ :wq “ to save and quit the script. (Refer to the Fig 4-7)
(2) Type “ chmod
755
/etc/init.d/hello “ to change authority.
LinPAC-5000 SDK Manual:18
(3) Type “ cd
(4) Type ” ln
/etc/rc2.d “ to into default run level.
-s ../init.d/hello
/etc/rc2.d/S85hello “ to make a symbolic link into the
script file and it will be executed automatically at boot time. (Refer to the Fig 4-8)
Fig. 4-7
LinPAC-5000 SDK Manual:19
Fig. 4-8
4.5.2 Disabling program run at boot time
The steps are as follows :
(1) Type “ cd
/etc/rc2.d “ to into default run level.
(2) Type “ mv
S85hello
xS85hello “ to rename the S85hello symbolic link for turn off
running program automatically at boot time.
LinPAC-5000 SDK Manual:20
4.6 Automatic login
Log the specified user onto the console (normally /dev/tty1) when the system is first
booted without prompting for a username or password using mingetty command.
The steps are as follows :
(1) Login as root and edit /etc/inittab
(2) Modify the entry for the first terminal― tty1
Below user can see the modified part of LinPAC-5000 /etc/inittab file (Refer to the Fig
4-9), and it will autologins into the root account after reboot the LinPAC-5000.

5.2 General GCC Instructions
GCC is a cross-compiler provided by GNU and it can compile source code written by
ANSI C or by Tranditional C into executable files. The executable file compiled by GCC can
run in different OSs and in different Hardware systems. Therefore GCC is very popular
within the Unix system which is a large part of why its popularity is growing so well.
Furthermore it is free, and therefore can be downloaded via your network with ease.
First, Fig. 5-1 illustrates the compilation procedure within Linux:
Fig. 5-1
Second, we will list some GCC instructions to let users compile *.c to *.exe smoothly and
to explain the parameters for GCC in its compilation process.

5.3 A Simple Example – Helloworld.c
In this section, we will introduce how to compile the helloworld.c to helloworld.exe and
transfer the helloworld.exe to the LinPAC-5000 by using FTP. Finally executes this file via
the Telnet Server on the LinPAC-5000. These steps can be accomplished in one pc without
another monitor for the LinPAC-5000. In this example, no ICP DAS modules are used. If you
want to use the modules of ICP DAS to control your system, you can refer to demo in the
chapter 7.
These processes can be divided into three steps and thet are given as below:
STEP 1 :( Compile helloworld.c to helloworld.exe )
(1) Open LinPAC-5000 SDK ( refer to step 8 in section 2.1) and type
“ cd examples/common ” to change the path to
C:/cygwin/LinCon8k/examples/common. Type “dir/w” and you can see the
helloworld.c file. (refer to Fig.5-2)
LinPAC-5000 SDK Manual:27
Fig. 5-2
(2) Type in “arm-linux-gcc –o helloworld.exe helloworld.c“ to compile helloworld.c into
helloworld.exe. Then type “dir/w“ to see the helloworld.exe file. (refer to Fig.5-3)
Fig. 5-3
LinPAC-5000 SDK Manual:28
STEP 2 :( Transfer helloworld.exe to the LinPAC-5000 )
There are two methods for transferring files to the LinPAC-5000:
< Method one > By Using the “DOS Command Prompt”:
(1) Open a “DOS Command Prompt” and type in the ftp IPAddress of the LinPAC-5000
( Example:ftp 192.168.0.200) to connect to the FTP Server on the LinPAC-5000. Then
type the User_Name and Password ( “ root ” is the default value. )
to accomplish the
connection from the PC to the LinPAC-5000.
(2) Before transferring your files to the LinPAC-5000, type in the “bin” command to make the
file transfer to the LinPAC-5000 in binary mode. (refer to Fig.5-4)
Fig.5-4
(3) Type in “ put
C:/cygwin/LinCon8k/examples/common/helloworld.exe
helloworld.exe ” to transfer helloworld.exe to the LinPAC-5000. If it shows the message
of “ Transfer complete ”, then the whole transferring process has been accomplished. If
you need to disconnect from the LinPAC-5000, type in the “ bye ” command to return to
the PC console. (refer to Fig.5-5).
Fig.5-5
LinPAC-5000 SDK Manual:29
< Method two > By Using FTP Software:
(1) Open the FTP Software and add a ftp site to the LinPAC-5000. The User_Name and
Password default value is “root”. Then click the “Connect” button to connect to the ftp
server of the LinPAC-5000. (refer to Fig.5-6).
Fig.5-6
(2) Upload the file - Helloworld.exe to the LinPAC-5000. (refer to Fig.5-7).
Fig.5-7
LinPAC-5000 SDK Manual:30
(3) Choose helloworld.exe in the LinPAC-5000 and click the right button of mouse to choose
the “ Permissions ” option. Then type 777 into the Numeric textbox. (refer to Fig.5-8
and Fig.5-9 ).
Fig.5-8
Fig.5-9
STEP 3 :( Telnet to the LinPAC-5000 and execute program)
(1) Open a “ DOS Command Prompt ” and then type in the telnet IPAddress of the
LinPAC-5000 ( Example:telnet 192.168.0.200 ) to connect to the telnet server of the
LinPAC-5000. Then type the User_Name and Password (“ root ” is the default
value. ). If it shows the “ # “ prompt character, the process of connecting from your PC to
the telnet server of the LinPAC-5000 is finished. (refer to Fig.5-10)
Fig.5-10
LinPAC-5000 SDK Manual:31
(2) Type in the “ls -l“ command in order to list all the files in /root and to see the
helloworld.exe file. Then type in the “chmod 777 helloworld.exe” command to change
the authority of helloworld.exe and then type in the “ls -l“ command again to see
“helloworld.exe”. This means that the file is executable. Type in “./helloworld.exe“ to
execute the file and it will show “ Welcome to LinPAC-5000 ”. Then all the steps from
compile, transfer to telnet to execute program will be completed. (refer to Fig.5-11)
Fig.5-11
LinPAC-5000 SDK Manual:32
5.4 i-Talk Utility
The i-Talk utility provides six instructions that make it convenient for users to access
the modules and hardware in the LinPAC-5000 and they are placed in the path -
/usr/local/bin. Fig. 5-12 describes the functions of i-Talk utility.

LinPAC-5000 SDK Manual:33
6. LIBI8K.A
In this section, we will focus on examples for the description of and application of the
functions found in the Libi8k.a. The Libi8k.a functions can be clarified into 3 groups which
are listed in Fig. 6-1.
Fig. 6-1
Functions (1) and (2) in the Libi8k.a are the same as with the DCON.DLL Driver
(including Uart.dll and I7000.dll) as used in the DCON modules (High profile I-7000/I-8000
/I-87000 in serial communication). You can refer to the DCON.DLL Driver manual which
includes the functions on how to use DCON modules (http://www.icpdas.com/products/).
The DCON.DLL Driver has already been wrapped into the Libi8k.a. Functions (3) of the
Libi8k.a consist of the most important functions as they are specially designed for I-8000
modules in the LinPAC-5000 slots. They are different from functions (1) and (2) because the
communication of I-8000 modules in the LinPAC-5000 slots are parallel and not serial.
Therefore ICP DAS rewrote I8000.c to Slot.c especially for I-8000 modules in the
LinPAC-5000 slots.
Here we will introduce all the funcitions for slot.c and they can be divided into night
LinPAC-5000 SDK Manual:34
parts for ease of use.
1.
System Information Functions;
2.
Watch Dog Timer Functions;
3.
EEPROM Read/Write Functions;
4.
Digital Input/Output Functions;
5.
Analog Input Functions;
6.
Analog Output Functions;
When using the development tools to develop applications, the msw.h file must be
included in front of the source program, and when building applications, libi8k.a must be
linked. If you want to control ICP DAS I/O remote modules like i7k, i8k and i87k through
COM1 or COM2 or COM3 of the LinPAC-5000, the functions are all the same with DCON
DLL.
LinPAC-5000 SDK Manual:35

„ Send_Binary
Description:
Send out the command string by fix length, which is controlled by the parameter “iLen”.
The difference between this function and Send_cmd is that Send_Binary terminates the
sending process by the string length “iLen” instead of the character "CR"(Carry return).
Therefore, this function can send out command string with or without null character under
the consideration of the command length. Besides, because of this function without any error
checking mechanism (Checksum, CRC, LRC... etc.), users have to add the error checking
information to the raw data by themselves if communication checking system is required.
Note that this function is usually applied to communicate with the other device, but not for
ICP DAS DCON (I-7000/8000/87K) series modules.

7. Demo of LinPAC-5000 Modules With C Language
In this section, we will focus on examples for the description and application of the
control functions on the I-7000/I-8000/I-87k series modules for use in the LinPAC-5000.
After you install the LinPAC-5000 SDK, all these demo programs as below are in the path of
“c:/cygwin/LinCon8k/examples”.
7.1 I-7k Modules DIO Control Demo
This demo – i7kdio.c will illustrate how to control DI/DO with the I-7050 module (8 DO
channels and 7 DI channels). The address and baudrate of the I-7050 module in the RS-485
network are 02 and 9600 separately.
The result of this demo allows the DO channels 0 ~ 7 output and DI channel 2 input.
The source code of this demo program is as follows:
#include<stdio.h>
#include<stdlib.h>
#include "msw.h"
char szSend[80], szReceive[80], ans;
WORD wBuf[12];
float fBuf[12];
/* ------------------------------------------------------------------- */
int main()
{
int wRetVal;
// Check Open_Com2
wRetVal = Open_Com(COM2, 9600, Data8Bit, NonParity, OneStopBit);
if (wRetVal > 0) {
printf("open port failed!\n");
return (-1);
}
// ***** 7050 DO && DI Parameter *******
wBuf[0] = 2;
// COM Port
wBuf[1] = 0x02;
// Address
wBuf[2] = 0x7050;
// ID
wBuf[3] = 0;
// CheckSum disable
wBuf[4] = 100;
// TimeOut , 100 msecond
wBuf[5] = 0x0f;
// 8 DO Channels On
wBuf[6] = 0;
// string debug
LinPAC-5000 SDK Manual:105
// 7050 DO Output
wRetVal = DigitalOut(wBuf, fBuf, szSend, szReceive);
if (wRetVal)
printf("DigitalOut_7050 Error !, Error Code=%d\n", wRetVal);
printf("The DO of 7050 : %u \n", wBuf[5]);
// 7050 DI Input
DigitalIn(wBuf, fBuf, szSend, szReceive);
printf("The DI of 7050 : %u \n", wBuf[5]);
Close_Com(COM2);
return 0;
}
Follow the below steps to achieve the desired results:
STEP 1:( Write i7kdio.c )
Copy the above source code and save it with the name - i7kdio.c or get the file from
C:\cygwin\LinCon8k\examples\i7k.
STEP 2:( Compile i7kdio.c to i7kdio.exe )
Here we will introduce two methods to accomplish step 2.
< Method One > Using Batch File ( lcc.bat )
Execute Start>Programs>ICPDAS>LinPAC-5000 SDK> LinPAC-5000 Build
Environment to open LinPAC-5000 SDK and change the path to
C:\cygwin\LinCon8k\examples\i7k. Then type lcc i7kdio to compile i7kdio.c to i7kdio.exe.
( refer to Fig. 7-1 )
Fig. 7-1
LinPAC-5000 SDK Manual:106
< Method Two > Using Compile Instruction
If you choose this method, change the path to C:\cygwin\LinCon8k\examples\i7k and
then type arm-linux-gcc -I../../include –lm –o i7kdio.exe i7kdio.c ../../lib/libi8k.a to compile
i7kdio.c to i7kdio.exe. ( refer to Fig. 7-2 )
Fig. 7-2
LinPAC-5000 SDK Manual:107
STEP 3:( Transfer i7kdio.exe to the LinPAC-5000 )
Here we introduce two methods for achieving this purpose.
< Method One > Using FTP Software
(1) Open a FTP Software and add a ftp site of the LinPAC-5000. The User_Name and
Password default value is “ root ”. Then click the “Connect” button to connect to the ftp
server of the LinPAC-5000. (refer to Fig.7-3).
Fig.7-3
(2) Upload the file – i7kdio.exe to the LinPAC-5000. (refer to Fig.7-4).
Fig.7-4
LinPAC-5000 SDK Manual:108
(3) Choose i7kdio.exe in the LinPAC-5000 and click the right mouse button to choose
the “ Permission ”option. Then type 777 into the Numeric blank textbox. (refer to Fig.7-5
and
refer to Fig.7-6 ).
Fig.7-5
Fig.7-6
< Method Two > Using DOS Command Prompt
Open DOS Command Prompt and type ftp IP Address of LinPAC-5000 in order to
connect to the ftp server of the LinPAC-5000. Then input User Name and Password (root is
the default value ) to login to the LinPAC-5000. Type bin to make the file transference in
“binary” mode.
Then type put c:/cygwin/lincon8k/examples/i7k/i7kdio.exe i7kdio.exe to transfer the
i7kdio.exe to the LinPAC-5000. After the “Transfer complete” message appears, the process
of transference would have been completed.( refer to Fig. 7-7 )
Fig. 7-7
LinPAC-5000 SDK Manual:109
STEP 4:( Telnet to the LinPAC-5000 to execute i7kdio.exe )
Type telnet IP Address of LinPAC-5000 into the remote control the LinPAC-5000 and
input your User Name and Password (root is the default value ) to login to the
LinPAC-5000. And then type chmod 777 i7kdio.exe to make i7kdio.exe executable. Type
i7kdio.exe to execute i7kdio.exe. ( refer to Fig. 7-8 and Fig. 7-9 )
Fig. 7-8
Fig. 7-9
“ The DO of I-7050:255 ( =2^8-1 )” means DO channel 0 ~ 7 will output and “ The DI
of I-7050:123 ( =127-2^2 )” means there is input in DI channel 2.
7.2 I-7k Modules AIO Control Demo
This demo – i7kaio.c will illustrate how to control the AI/AO with the I-7017 (8 AI
channels ) and I-7021 modules (1 AO channel). The address for the I-7021 and I-7017
modules are in the RS-485 network where 05 and 03 are separate and the baudrate is 9600.
The result of this demo allows the I-7021 module’s AO channel to output 3.5V and the
I-7017 ‘s AI channel 2 to input. The source code of this demo program is as follows:
LinPAC-5000 SDK Manual:110
#include<stdio.h>
#include<stdlib.h>
#include "msw.h"
char szSend[80], szReceive[80];
WORD wBuf[12];
float fBuf[12];
/* ------------------------------------------------------------------- */
int main()
{
int i,j, wRetVal;
DWORD temp;
wRetVal = Open_Com(COM2, 9600, Data8Bit, NonParity, OneStopBit);
if (wRetVal > 0) {
printf("open port failed!\n");
return (-1);
}

wBuf[6] = 0;
// string debug
fBuf[0] = 3.5;
// Analog Value
wRetVal = AnalogOut(wBuf, fBuf, szSend, szReceive);
if (wRetVal)
printf("AO of 7021 Error !, Error Code=%d\n", wRetVal);
else
printf("AO of 7021 channel %d = %f \n",i,fBuf[0]);
//--- Analog Input ---- **** 7017 -- AI ****
j = 1;
wBuf[0] = 2;
// COM Port
wBuf[1] = 0x03;
// Address
wBuf[2] = 0x7017;
// ID
wBuf[3] = 0;
// CheckSum disable
wBuf[4] = 100;
// TimeOut , 100 msecond
wBuf[5] = j;
// Channel of AI
wBuf[6] = 0;
// string debug
LinPAC-5000 SDK Manual:111
wRetVal = AnalogIn(wBuf, fBuf, szSend, szReceive);
if (wRetVal)
printf("AI of 7017 Error !, Error Code=%d\n", wRetVal);
else
printf("AI of 7017 channel %d = %f \n",j,fBuf[0]);
Close_Com(COM2);
return 0;
}

8.1 Introduction of COM1 Port of LinPAC-5000
COM1 is an internal I/O expansion port of the PDS-8x2. This port is used to connect the
I/O expansion board(XW-board) plugged into the PDS-8x2 embedded controller. Users must
use the serial command to control the I/O expansion board. For controlling the I/O expansion
board, you must input the Com-port parameters and call the Open_Com function to open
the com1 port based on the appropriate settings. This is like the serial address, and you can
send out the control commands to the I/O module which is plugged into this slot. Therefore
the module’s serial address for its slot is 0. A detailed example is provided below:
For Example:
int slot=1;
unsigned char port=1;
// for all modules in com1 port of PDS-8x2
DWORD baudrate=115200;
char data=8, parity=0, stopbit=1 ;
Open_Slot(slot);
Open_Com(port, baudrate, data, parity, stopbit);
// send command...
Close_Com(port);
Close_Slot(slot);
LinPAC-5000 SDK Manual:115
8.2 Introduction of COM2 Port of LinPAC-5000
This COM2 port provides RS-485 serial communication (DATA+ and DATA-) and is
located on bottom-right corner in the LinPAC-5000. You can connect to the RS-485 device
with modules like the I-7000 serial modules(DCON Module) via this port. That is, you can
control the ICP DAS’s modules directly from this port with any converter. ICP DAS will
provide very easy to use functions with libi8k.a and then you can easily handle the I-7000
series modules. Below is an example of the program code demo.

10. Additional Support
In this chapter, ICP DAS provides extra module supported and instructions to enhance
LinPAC-5000 functionality and affinity.
10.1 GUI Funtion Support
Now “X-window“ is supported the VGA solution(LP-51x1, LP-52x1, LP-54x1, LP-55x1)
and when the LinPAC-5000 boot up, the GUI like “Windows screen” will show up. The
most important thing is that users can write GUI programs and run them in the LinPAC-5000.
The GUI Library in the LinPAC-5000 is provided with GTK+ v1.2 & v2.0 Library. Therefore
users can design their own “SCADA” screen by the GTK+ Library in the LinPAC-5000. In
the meanwhile, we provide some GUI demo programs to control I/O modules of ICP DAS
and assist users to develop own GUI programs quickly. These demo programs are placed in
the path - C:\cygwin\LinCon8k\examples\gui after users install the LinPAC-5000 SDK.
Refer to the Fig. 10-1) (Note: This function can not support LinPAC-53x1)
Except GTK+ GUI Function, “Java GUI” is also supported in the LinPAC-5000. So if
users are familiar with Java, users can also use Java to develop own GUI programs. But just
Awe and Swing v1.1 elements below are supported in the LinPAC-5000. To execute Java
GUI program – Stylepad.jar in the LinPAC-5000, users just type in “java -jar Stylepad.jar
-cp .:Stylepad.jar”. Then it will take some time to run up the Java GUI program.
Fig. 10-1
LinPAC-5000 SDK Manual:121
10.1.1 Disable X-window
LinPAC-5000 can boot without loading X-window by the steps as follows :
(1) Type “cd
(2) Type ”ls
/etc/rc2.d“ to into default run level.
-al” to see the S98Xserver link into ../init.d/startx.
(3) Type ”mv
S98Xserver
xS98Xserver“ to rename the S98Xserver for turn off
X-window. Then exit and reboot LinPAC-5000.
10.1.2 Enable X-window
If you type the “ls -al /etc/rc2.d“ that can fine the link about ../init.d/startx, and then type
the “mv
xS98Xserver S98Xserver “ to rename the xS98Xserver for turn on X-window or
else if you can’t fine any link about ../init.d/startx, and please follow the below steps :
(1) Type “cd
/etc/rc2.d“ to into default run level.
(2) Type ”ln
-s ../init.d/startx
/etc/rc2.d/S98Xserver“ to make a symbolic link into
the script file of X-window for turn on X-window. Then exit and reboot LinPAC-5000.
10.2 ScreenShot Support
There is a screenshot program - “fbshot” built in to let users to catch the
LinPAC-5000
screen
conveniently.
Users
just
type
in
“fbshot
-d
/dev/fb0
/mnt/hda/catch1.png” and the screen will be catched and saved to the file -
/mnt/hda/catch1.png. If users want to take a look the picture, just type in “vi
/mnt/hda/catch1.png”. ( Note : vi is placed in the path : /mnt/hda/opt/bin so users need to
plug microSD card in the LinPAC-5000 first. ) If users want to know the detailed parameters
of fbshot, just type in “fbshot --help”.
LinPAC-5000 SDK Manual:122
10.3 WebCAM Support
WebCAM is also supported in the LinPAC-5000 and Logitech brand works successfully
now. Other brands will need to do a test. Please follow the steps to make the Webcam work
smoothly :
(1) Connect the webcam to the LinPAC-5000 with “USB Interface”.
(2) Reboot the LinPAC-5000.
(3) Open a “Command Prompt”. Type in “insmod pwc.ko” to load the gqcam
program decompressor and then type in “gqcam” to see the webcam screen. If
users want to know the detailed parameters of gqcam, just type in “gqcam --help”.
If users want to catch the picture through webcam, users can use gqcam program to do
that. Please follow the steps as below :
(1) Click “File/Save Image…”
(2) At “Gqcam: Save Image” screen, input the path and file name in the “File Field”
and then click “OK“ button.
Note: This function can not support LinPAC-53x1.
10.4 Screen Resolution Setting
There are three modes to adjust the screen resolution of LinPAC and they are 640*480,
800*600. Users can edit the file : /etc/init.d/fbman to modify the setting and follow the below
steps :
(1) When users open the file : /etc/init.d/fbman, users can see the following lines :
#/usr/sbin/fbset -n 640x480-60
/usr/sbin/fbset
-n 800x600-70
It means that the resolution setting is 800*600.
(2) If users want to change the setting to be 640*480, just remove the “#” mark in line 2
and add the “#” mark in line 1. Please see the following setting result :
/usr/sbin/fbset
-n
640x480-60
#/usr/sbin/fbset
-n
800x600-70
After rebooting the LinPAC, the setting will work.
Note: This function can not support LinPAC-53x1.
LinPAC-5000 SDK Manual:123
10.5 Network Support
There are many network functions already built in the LinPAC-5000. Here are the
network functions supported in the LinPAC-5000 :
(1) Support UPnP :
UPnP is “Universal Plug and Play” and allows automatic discovery and control of
services available on the network from other devices without user intervention. Devices that
act as servers can advertise their services to clients. Client systems, known as control points,
can search for specific services on the network. When they find the devices with the desired
services, the control points can retrieve detailed descriptions of the devices and services
and interact from that point on.
(2) Support VPN
VPN is “Virtual Private Network” and describes a network that includes secure
remote access for client computers. It can be explained best by looking at its parts. “Virtual”
describes the fact that the network doesn't need to be physically connected directly. The
“Private” confirms that the data is encrypted and can only be viewed by a defined group.
The last word, “Network” means that the users configured for VPN can be connected and
share files or information. So it's extremely difficult for anyone to snoop on confidential
information through VPN. (Refer to the Fig. 10-2)
Fig. 10-2
LinPAC-5000 SDK Manual:124
(3) Support QoS
QoS is “Quality of Service”. It means when the kernel has several packets to send out
over a network device, it has to decide which ones to send first, which ones to delay, and
which ones to drop. With Linux QoS subsystem, it is possible to make very flexible traffic
control. Let users be able to control flow rate of assigned port to improve the network quality.
(4) Support Wireless LAN
“Wireless communication” is a networking technology allowing the connection of
computers without any wires and cables, mostly using radio technology (and sometime
infrared). It's called LAN because the range targeted is small ( generally within an office, a
building, a store, a small campus, a house... ). This technology is slowly growing and Linux
is able to take advantage of some of the wireless networks available.
If
users
plug
wireless
card
in
the
LinPAC-5000,
users
need
to
modify
/etc/network/interfaces.
(5) Support Dual LAN
Dual LAN means that users can combine wireless and cable network together through
LinPAC-5000. Therefore the communication between Cable LAN and Wireless LAN. If one
of these LANs can connect to internet, then all the PC can connect to internet. (Refer to Fig.
10-3)
Fig. 10-3
LinPAC-5000 SDK Manual:125
(6) Support BlueTooth
The Bluetooth wireless technology is a worldwide specification for a small-form factor,
low-cost radio solution that provides links between mobile computers, mobile phones, other
portable handheld devices, and connectivity to the Internet. Now “BlueZ” is built in the
LinPAC-5000 and provides support for the core Bluetooth layers and protocols. It is flexible,
efficient and uses a modular implementation.
(7) Support Modem / GPRS / ADSL
LinPAC-5000 can be connected to the Internet with “Modem“, “GPRS“ or “ADSL“ mode.
The setup method is described separately as follows :
[ Modem ]
[ GPRS ]
If users want to connect the gprs modem to the COM3 of LinPAC-5000, users
should modify /etc/ppp/peers/wavecom to define COM port first. Please follow the
steps as below :
(1) Type “vi /etc/ppp/peers/wavecom”
(2) To find the “Serial device to which the GPRS phone is connected:” statement, and
add device name of COM port.
(3) Type “:wq“ to save and quit the script. ( Refer to the Fig. 10-4 )
Fig. 10-4
The default GPRS baudrate is “115200” in the LinPAC, so if users finish the setting
of gprs modem and connect the gprs modem to the COM1 of LinPAC-5000, just type in
“pppd call wavecom” and then LinPAC-5000 will be connected to the internet
automatically. Remember that the network interface card of LinPAC should stop first,
just type in “ifdown eth0” to stop it. If users type in “ifconfig” will see the “ppp0”
option.
LinPAC-5000 SDK Manual:126
[ ADSL ]
Users need to type in “adsl-setup” first to setup ADSL options. After that, users
need to type in “adsl-connect” to make LinPAC-5000 connect to the internet. If users
want to stop adsl connection, just type in “adsl-stop”.
(8) Support Firewall ( iptables function )
A firewall can controls outside access to a local network, locking out intruders to
ensure your systems and data safe on the inside, even against an intentional attack from
outside network.
(9) Provide Web Browser
Users can see the Web Page by using the Web Browser built in the LinPAC-5000.
Just type in “dillo” to open the web browser and input the web site address. ( Refer to
Fig 10-5 ) ( Note : dillo is placed in the path : /mnt/hda/opt/bin so users need to plug
microSD Card in the LinPAC first, and . )
Fig 10-5
Note: This function can not support LinPAC-53x1.
LinPAC-5000 SDK Manual:127
(10) Provide Apache Server
The Web Server - “Apache Server” has been built in the LinPAC-5000 and it will
be started automatically when boot up. These files are placed in the path -
/opt/apache2. Users can type like “http://192.168.0.200” to connect to the web server in
the LinPAC-5000. If it returns a successful web page, it means that the web server in the
LinPAC-5000 has been started. The index web page of Apache Server is in the path :
“ /opt/apache2/htdocs/ “.
These files placed in the microSD card are full functions of Apache Server. So if
users want to use other function of Apache Server that are not supported in the
LinPAC-5000, users just copy them to the path : /opt/apache2 and reboot.
10.6 Audio Function
