LV-677 User’s Manual

To setup the LCD, you need the component below:

1. A panel with LVDS interfaces.

2. An inverter for panel’s backlight power.

3. A LCD cable and an inverter cable.

For the cables, please follow the pin assignment of the connector to make a cable, because every panel has its own pin assignment, so we do not provide a standard cable; please find a local cable manufacture to make cables.

LCD Installation Guide:

2. Please check the datasheet of the panel to see the voltage of the panel, and set the jumper JVLCD to +5V or +3.3V.

3. You would need a LVDS type cable.

Based on Intel® 945GM(E) chipset with GMA (Graphic Media Accelerator) 950, the board supports Intel® DVMT (Dynamic Video Memory Technology) 3.0, which would allow the video memory to be allocated up to 224MB.

To support DVMT, you need to install the Intel GMA 950 Driver with supported OS.

BIOS Setup:

On-Chip Video Memory Size: This option combines three items below for setup.

On-Chip Frame Buffer Size:

This item can let you select video memory which been allocated for legacy VGA and

SVGA graphics support and compatibility. The available option is 1MB and 8MB.

Fixed Memory Size:

This item can let you select a static amount of page-locked graphics memory which will be allocated during driver initialization. Once you select the memory amount, it will be no longer available for system memory.

DVMT Memory Size:

This item can let you select a maximum size of dynamic amount usage of video memory, the system would configure the video memory depends on your application, this item is strongly recommend to be selected as MAX DVMT.

Chapter 4 <BIOS Setup>

The motherboard uses the Award BIOS for the system configuration. The Award BIOS in the single board computer is a customized version of the industrial standard BIOS for

IBM PC AT-compatible computers. It supports Intel x86 and compatible CPU architecture based processors and computers. The BIOS provides critical low-level support for the system central processing, memory and I/O sub-systems.

The BIOS setup program of the single board computer let the customers modify the basic configuration setting. The settings are stored in a dedicated battery-backed memory, NVRAM, retains the information when the power is turned off. If the battery runs out of the power, then the settings of BIOS will come back to the default setting.

The BIOS section of the manual is subject to change without notice and is provided here for reference purpose only. The settings and configurations of the BIOS are current at the time of print, and therefore they may not be exactly the same as that displayed on your screen.

To activate CMOS Setup program, press ＜DEL＞ key immediately after you turn on the system. The following message “Press DEL to enter SETUP” should appear in the lower left hand corner of your screen. When you enter the CMOS Setup Utility, the Main

Menu will be displayed as Figure 4-1. You can use arrow keys to select your function, press ＜Enter＞ key to accept the selection and enter the sub-menu.

GPIO0…..GPIO7 bit0……bit7

-o 2E 87 ;enter configuration

-o 2E 87

-o 2E 29

-o 2F 40 ;enable GPIO function

-o 2E 07

-o 2F 07 Select Logic Device 7

-o 2E F0

-o 2F xx ;set GPIO as input/output; set ‘1’ for input,’0’for output

-o 2E F1

-o 2F xx ;if set GPIO’s as output,in this register its value can be set

Optional :

-o 2E F2

-o 2F xx ; Data inversion register ; ‘1’ inverts the current valus of the bits ,’0’ leaves them as they are

-o 2E 30

-o 2F 01 ; active GPIO’s
