CHAPTER 4 Software Functionality This chapter details the Windows® Windows® CE 5.0 operating system. Sections include: • Introduction • Windows® CE Startup Procedure • Upgrade Procedure • Utilities • Network • M-system DOC Flash File System • Application Program Development • TREK-725 Windows® CE 5.
4.1 Introduction The TREK-725 is an embedded system using the Windows® CE 5.0 OS. Windows® CE 5.0 is a compact OS that occupies less storage space and system resources compared with other operating systems such as Windows® NT or Windows® XP. By its modular nature, it is possible to choose only those functions that are needed for a particular application. This not only reduces the system resources required, but also reduces start-up time.
4.2 Windows CE Startup Procedure Windows CE can be loaded by three methods, through on-board flash, PCMCIA/CF card, and Ethernet. The presence of an image file (NK.bin) on a PCMCIA/CF card forces TREK-725 to boot from this PCMCIA/CF card. Besides booting from PCMCIA/CF card, HyperTerminal can be used to configure the method of downloading a Windows CE image by connecting a null modem cable between a PC COM port and the TREK725 COM1 port then following these steps. 4.2.1 Setting up HyperTerminal on PC 1.
2. Name the HyperTerminal session. Press “OK” Figure 4.3: Naming HyperTerminal 3. Select the PC COM port used to connect to the TREK-725.

Figure 4.5: Configure COM port parameters Now, HyperTerminal is ready to use. Connect a null modem cable from the PC COM port to the TREK-725 COM1 port. See section 1.6 for the location of the TREK-725 COM1 port. 4.2.2 Choosing an image download method 1. Power on TREK-725.
2. Press “SPACE” to enter the EBOOT Configuration Options window when the HyperTerminal shows the screen below. Figure 4.6: TREK-725 boot up window 3. Configure EBOOT Configuration Options. Figure 4.
Option(0) IP address Choosing this option allows the configuration of the static IP address that is used if DHCP is not enabled. This information is configured once and stored in flash for subsequent downloads. The following prompt is displayed: Enter new IP address: You should enter a decimal representation of the IP address with each byte separated by a decimal point. If you enter no data at the prompt, the IP address is not changed. If you enter any numbers, they are used.
Option (5) Boot Delay Choosing this option allows the configuration of the number of seconds that the boot loader waits for user input before continuing with the image download or launch. The following prompt is displayed: Enter maximum number of seconds to delay [1-255]: Option (6) DHCP Choose this option to enable or disable DHCP. When DHCP is enabled the static IP address is not used. When DHCP is disabled, the static IP address is used.
Option (F) Format Flash Choose this option to format the flash. This will not overwrite EBOOT or EBOOT parameters. Option (L) Launch Existing Flash Resident Image Now Choose this option to exit the menu, save any applicable changes that were made and then launch the previously programmed flashed image. Option (M) Display Mode Setup Mode (0) (800x600), Mode (1) (640x480), Mode (2) (1024x768), Mode (3) (320x24) Choose this option to configure the display resolution.
4.2.3 EBOOT configuration examples Ex1: Launch on-board flash image Do not enter the EBOOT Configuration menu, or in the EBOOT Configuration menu choose option (L) to launch the on-board flash image. Ex2: Download a Windows CE image over Ethernet without programming an image into Flash. 1. Set option (7) to DISABLE. 2. Choose option (D) to start downloading the image. Ex3: Download Windows CE image from Ethernet and program this image into Flash. 1. Set option (7) to ENABLE. 2.
2. Insert the CF storage card in to the TREK-725, then launch UpgradeIXP_1.01.07.exe. Figure 4.8: Image files and upgrade utility in CF storage card 3. Check the items you want to upgrade as shown in Figure 4.8. If you want to upgrade the boot logo, you can input the path of the bitmap file in the edit box or click the ‘Browse’ button to select the file. Note: The option “NK.NB0 (Normal, XIP)” means that the nk.nb0 will be written directly to the flash ROM, and “NK.NB0 (Compressed)” means that nk.
4. Press the ‘Apply’ button. The items you selected will be written to the flash ROM. See Figure 4.9. Figure 4.9: Press Apply button to upgrade on-board flash ROM Reboot the system after the upgrade process is done. 4.4 Utilities There are several useful utilities added to the standard Windows® CE 5.0 OS. 4.4.1 System Configurator System Configurator is an outstanding utility designed by Advantech Windows® CE software team.

4.4.4 Display Sometimes it is unnecessary to have the display attached to the TREK725 fully powered all day. The Display page provides two frequently used functions—display resolution and brightness adjustment. Figure 4.13: Display configuration NOTE: Users can set the idle time to turn off the backlight automatically from the backlight page in the Display Properties applet of the Control Panel. When the backlight is off, the mouse, keyboard, or touchscreen can turn it on again.
Figure 4.14: Display Properties dialog 4.4.5 Watchdog timer It is important in industrial applications that control systems rarely crash, or are capable of self-recovery if they are halted somehow. The watchdog function is provided to reset the TREK-725 if the software crashes. There is a countdown timer inside the watchdog function. The user’s application program enables the watchdog timer, then regularly reloads this countdown timer.
Figure 4.15: Watchdog timer 4.4.6 Miscellaneous The Misc page provides several functions as described below. The “Registry” block provides registry save, clear, and view functions. The “MAC ID” block shows the network MAC address. The “COMM” block provides IPConfig and ActiveSync communication functions. The “Reset” Block provides “Cold Boot” and “Start Upgrade” functions. “Cold Boot” is used to reboot the system.
Figure 4.16: Miscellaneous settings 4.4.7 Startup execution The TREK-725 has a useful function called “Startup execution”. After the system boots up, the startup execution function automatically begins. This function is useful for control systems to initialize processes or other procedures. In TREK-725, there is one way to configure the “Startup” function. Method 1. Create a “startup” directory on a CF storage card or in a folder called “\Mounted Volume\”. 2.
4.4.8 Hotkey Configuration The TREK-725 provides a utility named HotkeyControl.exe for the user to configure the hotkeys. Figure 4.17: Hotkeys Control 4.5 Network 4.5.1 Networking via Ethernet TREK-725 has one built-in 100Base-T Ethernet controller.
