4.1 S/W Introduction
The mission of Advantech Embedded Software Services is to "Enhance quality of life
with Advantech platforms and Microsoft Windows® embedded technology." We
enable Windows® Embedded software products on Advantech platforms to more
effectively support the embedded computing community. Customers are freed from
the hassle of dealing with multiple vendors (Hardware suppliers, System integrators,
Embedded OS distributor) for projects. Our goal is to make Windows® Embedded
Software solutions easily and widely available to the embedded computing commu-
nity.
4.2 Driver Installation
4.2.1 Windows XP professional
To install the drivers for Windows XP Professional, insert the CD into the CD-Rom, it
will auto-detect the hardware platform and then pop up with the “Embedded Comput-
ing Install Wizard” box; just select the drivers that you want to install then click “Install
All Selected Drivers”. Follow the Driver Setup Wizard instructions; click "Next" to
complete the installation.
4.2.2 Other OS
To install the drivers for Other Windows OS or Linux, please browse the CD to run the
setup file under each chipset folder on the CD-ROM.

4.3.1 SUSI Introduction
To make hardware easier and convenient to access for programmers, Advantech has
released a suite of API (Application Programming Interface) in the form of a program
library. The program Library is called Secured and Unified Smart Interface or SUSI
for short.
In modern operating systems, user space applications cannot access hardware
directly. Drivers are required to access hardware. User space applications access
hardware through drivers. Different operating systems usually define different inter-
face for drivers. This means that user space applications call different functions for
hardware access in different operating systems. To provide a uniform interface for
accessing hardware, an abstraction layer is built on top of the drivers and SUSI is
such an abstraction layer. SUSI provides a uniform API for application programmers
to access the hardware functions in different Operating Systems and on different
Advantech hardware platforms.
Application programmers can invoke the functions exported by SUSI instead of call-
ing the drivers directly. The benefit of using SUSI is portability. The same set of API is
defined for different Advantech hardware platforms. Also, the same set of API is
implemented in different Operating Systems including Windows XP and Windows
CE. This user’s manual describes some sample programs and the API in SUSI. The
hardware functions currently supported by SUSI can be grouped into a few catego-
ries including Watchdog, I

C, SMBus, GPIO, and VGA control. Each category of API
in SUSI is briefly described below.
