The Engine of SPC-57 is constructed by the combination of 2 PCBA – one  
mainboard and one I/O board. The mainboard is slightly modified based on  
Advnatech standard product PCM-7230 to fulfill SPC-57 specification. In this manual,  
we will still use PCM-7230 to mean the mainboard although it is slightly different  
from our standard product. The PCM-7230 SBC for SPC-57 is a 3.5” (145mm x 102  
mm x 21.1mm) single board computer with the Intel® PXA255 processor running at  
200 MHz. The milli-watt power consumption by its kernel makes the PCM-7230  
suitable for power conscious applications.

4.1 Introduction  
The SPC series is one embedded system with Windows® CE.NET OS. The Windows®  
CE.NET is a compact OS that occupies less storage space or system resources  
compared with other operating systems such as Windows® NT or Windows® XP. By  
its modular nature, it is possible to choose those functions that are useful for specific  
application. Not only reducing the system resources required, but also reduces start-up  
time. In the field of embedded applications, this is an appealing feature because the  
impact of downtime would be minimized.  
Furthermore, the small storage space it needs makes OS on solid-state disk possible, which implies  
higher robustness to harsh environments.  
Figure 4.1 Windows® CE.NET on the SPC Series  
4.2 Windows CE Startup Procedure  
Windows CE can be loaded by two methods, first is by Compact Flash card, and  
second is by on-board flash chip. Compact Flash card is high boot priority than  
on-board flash chip. In BOOTLOADER criteria, it will first read the Windows CE  
image in Compact Flash card. If Compact Flash card is unavailable or no Windows  
CE image inside, BOOTLOADER will load the Windows CE image from on-board  
flash chip. BOOTLOADER copy Windows CE image to DRAM and launch WinCE  
from DRAM, whenever loaded by Compact Flash card or on-board flash chip.  
Therefore, there are some advantages,  
1, Easy Windows CE image installation: Customer can copy Windows CE image they  
53  
Download from Www.Somanuals.com. All Manuals Search And Download.  
want to Compact Flash card, and then load this image by BOOTLOADER.  
2, Flexible Hardware design : Flash on board design is unnecessary. The Windows CE  
can be loaded by Compact Flash card.  
4.3 Upgrade Procedure  
After the OS image was built, we may want to burn it to the on-board flash ROM.  
Advantech provides the upgrade utility “Upgrade” to upgrade Bootloader image,  
WinCE image or boot logo to onboard flash ROM. The upgrade procedure is  
described as following :  
Step1. Copy “Upgrade” utility and image files you want (for example, NK.NB0,  
EBOOT.NB0, and WINDOWSCE.BMP ) to CF storage card.  
Note : NK.NB0 is WinCE image.  
EBOOT.NB0 is Bootloader image.  
WINDOWSCE.BMP is boot bitmap.  
Step2. Insert CF storage card to platform, and then launch Upgrade.exe.  
Figure 4.2 Image files and upgrade utility in CF storage card  
Step3. Check the items you want to upgrade as the figure shown below. If you want to  
upgrade boot logo, you can input the path of the bitmap file in the edit box or click  
‘Browse’ button to select the file.

Note: The difference between NK.NB0 (Compressed) and NK.NB0 (Normal, XIP) :  
The option “NK.NB0 (Normal, XIP)” means that the nk.nb0 will be upgraded directly  
to the flash ROM, and “NK.NB0 (Compressed)” means that we compress nk.nb0 first,  
and then write the compressed data to the flash ROM. :  
(1) Boot time : compressed image take more time in system bootup.  
(2) IPSM size : compressed OS image would result in larger IPSM size.  
Step4. Press ‘Apply’ button on the dialog. Then the items you select will be upgraded  
to the flash ROM. See Figure 4-4.  
Figure 4.4 Press Apply button in order to upgrade onboard flash ROM  
After the upgrade process done, to power off platform and power on it. On the first  
time boot, it will take about 1 minute to format the IPSM.  
4.4 Utilities  
There are several useful utilities added in the standard Windows® CE.NET OS:  
4.4.1 Regflash  
The utility "Regflash" is a convenient tool to save, overwrite or delete registry data, as  
well as erase the content of IPSM folder. From the Windows® CE.NET status bar, tap  
"Start/Run". Use the soft-keyboard to type "regflash" command in the command text  
box and press "OK". There are four selections here:  
Save to Flash, Delete from Flash, Save to CF Disk, Erase IPSM.  
Choose the options you want and press "Save" button to proceed. "Save to Flash"  
option was used to save the registry setting to on board flash ROM. In contrast,  
"Delete from Flash" option was intended to erase the on board registry data. "Save to  
CF Disk" option would save the registry data to CompactFlash card as a file  
"wince.reg". "Erase IPSM" option erase the IPSM region of the on board flash.  
Note: Please be careful using this utility "Regflash". This utility is able to overwrite  
all registry data.

Figure 4.5 Regflash utility  
It is important to keep the power normal during "Save to Flash" process. If the power  
were broken down during the registry saving process, then the registry would be lost  
and corrupted. On the next time you turn on platform, the system would load the  
default registry setting rather than the previously customized registry setting.  
4.4.2 Reboot  
The utility "Reboot" is a convenient tool to reset the system. From the Windows®  
CE.NET status bar, tap "Start/Run". Use the soft-keyboard to input "reboot" command  
in the command text box and press "OK". The other ways to reboot are clicking the  
“Reboot” button on the Watchdog page of the built-in utility System Configurator and  
hardware reboot button.  
Figure 4.6 Reboot the system  
4.4.3 Startup execution  
The SPC has one useful function call "Startup execution". After the system boot up,  
the startup execution function would automatically perform. This function is useful  
for control system to do the initialization processes or some other procedures. In SPC,  
56  
Download from Www.Somanuals.com. All Manuals Search And Download.  
there are two ways to perform "Starup" function.  
Method 1:  
Step1: Create "startup" directory in CF storage card or in folder "\IPSM\".  
Step2: Copy executable files to "startup" directory that is created by Step 1.  
Example:  
We copy two executable files "REGFLASH.exe" and "Notepad.exe" in  
"\IPSM\Startup", and then reboot the system. After the system boot up, the two  
executable files would automatically execute.  
Method 2:  
Step1: The same as Step1 in Method 1.  
Step2: Create a file called "startup.ini" in "startup" directory. Type in the commands  
you want to execute after boot up in that file.  
Example:  
Create "Startup.ini" in "\IPSM\Startup" directory and reboot the system. The content  
of startup.ini was listed below:  
\windows\tty.exe  
\windows\registry.exe  
After the system reboot, "\windows\ tty.exe" and "\windows\ registry.exe" would  
automatically execute. Be sure that the two methods are independent. It means they  
can be used simultaneously.  
4.4.4 Safemode  
SPC allow user to alter registry setting, and save it by either "regflash.exe" or the  
registry frame of the “Misc” page of the System Configurator. But sometimes user  
may make some non-appropriate registry setting, and cause SPC fail to boot. In the  
circumstance, the easiest way to boot up SPC is to use the default registry setting from  
the Windows® CE.NET image. When the SPC is booted up with the default registry  
setting, we say that it is working in "safemode". To enter "safemode", user must  
perform several steps as described below:  
Step 1: Create a file whose filename is "safemode" or a folder whose name is  
"safemode" in the CompactFlash card.  
Step 2: Insert the CompactFlash card into the SPC series platform.  
Step 3: Turn on the power switch of SPC series platform.

4.4.5.2 Calibration  
The Touch-screen page provides the calibration function. Click the "calibration"  
button, the "Stylus Properties" windows would appear. Then click "calibrate" button  
in the Stylus Properties window to enter calibration process. In the calibration process,  
user taps on the center of the target on the screen then the target will move to the next  
position. After calibration, press "OK" to leave Stylus Properties window, and then  
the Regflash utility process would automatically start to save the registry setting.

4.4.5.3 Display  
From time to time it is unnecessary to turn on the display attached to the SPC all the  
day. The Display page provides several frequently used functions such as turning off  
the LCD and backlight to elongate the display repair period, adjusting brightness or  
contrast. For example, if user wants the backlight turn-off setting function, he can  
press "setting" button. Then the backlight page of Display Properties of Control Panel  
will appear on the screen. Besides, user can click the "Off Now" button to turn off the  
backlight of the display panel immediately without waiting. Once the backlight was  
turned off, there were three inputs to turn it on: (1) mouse; (2) keyboard; (3)  
touch-screen; user can use any one of them to turn on the display. The lower  
“Brightness” and “Contrast” blocks have scroll bars by which users can tune  
brightness level of TFT LCD or the contrast level of passive matrix LCD.

4.4.5.4 WatchDog timer  
It is important in industrial applications that the control systems are rarely crashed, or  
are capable of self-reset if they are halted somehow. Watchdog function of automatic  
resetting system is therefore provided in SPC. There is a timer inside the watchdog  
function. User’s AP could invoke the associated APIs in Watchdog function to start  
the timer, then Watchdog function would repeat the countdown of the specified period  
of time to reboot the system if the user’s AP does not clear the timer in time  
periodically. The Watchdog function in the SPC provides eight different time  
intervals: 2 seconds, 5 seconds, 10 seconds, 30 seconds, 60 seconds, 2 minutes, 5  
minutes and 10 minutes. The “Enable" button is used to simulate the Watchdog  
function. Detail programming guide is illustrated at section 4.7.5. The “Sleep” button  
could make the system enter suspend mode as “Suspend” of “Start” could. Press the  
"SoftReset" button will cause system warm boot that clears DRAM, reloads all drivers  
and refresh the newest registry settings. Press the “REBOOT” button will cause the  
system cold boot.  
Figure 4.10 Watchdog timer  
4.4.5.5 Hotkeys  
There are 8 Hotkeys reserved for users on the SPC. These Hotkeys are  
assigned to invoke different application programs as defaults:  
Hot key 1: invokes Windows Explorer  
Hot key 2: invokes Advantech homepage  
Hot key 3: invokes System Configurator  
Hot key 4: invokes Windows Media Player

4.4.5.6 DIO  
There are 8 digital inputs and 8 digital outputs. This DIO page of the System  
Configurator can show their status. When the “Start” button is pressed, the 8  
DI will try to retrieve external inputs, then those pins having positive inputs will  
mark respective radial buttons inside the “Digital Input Status” block, others will  
make their radial buttons empty. On the other hand, when users use mouse,  
finger or stylus to check some of the 8 check boxes, the level of the related DO  
pins will be changed to positive level. The DO pin status will sustain until users  
change them again.

4.6 Intel Persistent Storage Manger (IPSM)  
4.6.1 Introduction to Intel Persistent Storage Manger  
Intel Persistent Storage Manager was designed and developed specifically as an  
enhancement to Microsoft Windows CE operating systems. IPSM eliminates extra  
disk-like storage such as storage cards, redundant RAM and ROM.  
4.6.2 IPSM folder in SPC Series  
SPC uses Intel Persistent Storage Manger to utilize the free space of flash ROM for  
persistent storage. The IPSM region in the system is located in "\IPSM" directory.  
Any file or directory stored in "\IPSM" directory would be keep persistently, even if  
the power of SPC were turned off. The user can store software or data in \IPSM rather  
in CF card to avoid inconvenience.

4.7 Application Program Development  
The SPC is bundled with built-in Windows® CE.NET operating system. In real  
application user need to execute various application programs on it. However, unlike  
its other CPU family, the Windows® CE.NET is a hardware-dependent operating  
system. That is to say, Windows® CE.NET application programs are only portable in  
the source code level. Users must rebuild the runtime file for a different Windows®  
CE.NET platform even though the source code may not be changed at all.  
4.7.1 System requirements  
• Intel® Pentium-90 CPU or more advanced  
• Microsoft® Windows® 2000 Professional or Windows® XP  
• Microsoft® eMbedded Visual Tools 4.0  
• Platform SDK for SPC

4.7.5 WDT Modules  
SPC is targeted to be the embedded device for web-enabled and data-acquisition  
systems. It is built-in with a useful dynamic link library, WATCHDOG.DLL, which  
has been designed to help AP developer easily implement his requirements of  
handling the system resources such as Watchdog timer and LCD brightness control  
etc. Programmers who are familiar with WIN32 API programming would feel very  
easy to use this DLL to create his functions. The DLL make its device services look as  
a file whose name is "WDT1:". The programmer could use this file name in  
"CreateFile()" to open it and get the file handler. Then the following controls of user  
required device services would be achieved by way of the file handler in one function  
call of "DeviceIOControl()". At most 5 applications can access watchdog timer  
simultaneously. The DeviceIOControl function is following:  
- DeviceIoControl  
74  
Download from Www.Somanuals.com. All Manuals Search And Download.  
This function sends a control code directly to a specified device driver, causing the  
corresponding device to perform the specified operation.  
BOOL DeviceIoControl(  
HANDLE hDevice,  
DWORD dwIoControlCode,  
LPVOID lpInBuffer,  
DWORD nInBufferSize,  
LPVOID lpOutBuffer,  
DWORD nOutBufferSize,  
LPDWORD lpBytesReturned,  
LPOVERLAPPED lpOverlapped);  
- Parameters  
hDevice  
[in] Handle to the device that is to perform the operation. Call the Create- File function to obtain a  
device handle.  
dwIoControlCode  
[in] Specifies the control code for the operation. This value identifies the specific operation to be  
performed and the type of device on which the operation is to be performed. No specific values are  
defined for the dwIo- ControlCode parameter. However, the writer of a custom device driver can define  
IOCTL_XXXX control codes, per the CTL_CODE macro.  
These control codes can then be advertised, and an application can use these control codes with  
DeviceIoControl to perform the driver-specific functions.  
lpInBuffer  
[in] Long pointer to a buffer that contains the data required to perform the operation.  
This parameter can be NULL if the dwIoControlCode parameter specifies an operation that does not  
require input data.  
nInBufferSize  
[in] Size, in bytes, of the buffer pointed to by lpInBuffer.  
lpOutBuffer  
[out] Long pointer to a buffer that receives the operation's output data.  
75  
Download from Www.Somanuals.com. All Manuals Search And Download.  
This parameter can be NULL if the dwIoControlCode parameter specifies an operation that does not  
produce output data.  
nOutBufferSize  
[in] Size, in bytes, of the buffer pointed to by lpOutBuffer.  
lpBytesReturned  
[out] Long pointer to a variable that receives the size, in bytes, of the data stored into the buffer  
pointed to by lpOutBuffer.  
The lpBytesReturned parameter cannot be NULL. Even when an operation produces no output data,  
and lpOutBuffer can be NULL, the Device-IoControl function makes use of the variable pointed to by  
lpBytesReturned. After such an operation, the value of the variable is without meaning.  
lpOverlapped  
[in] Ignored; set to NULL.  
- Return Values  
Nonzero indicates success. Zero indicates failure. To get extended error information, call GetLastError.  
WDT Control Codes  
There are 8 control codes for the operation codes in the WDT1 driver:  
1. IOCTL_ENABLE_WDT (0x1001):  
Enables the Watchdog timer on your application. Your application must trigger to Watchdog timer by  
IOCTL_ACCESS_WDT interface during specified period, otherwise the device will reboot
