7.4.1 Advantech SUSI Introduction
SUSI - A Bridge to Simplify & Enhance H/W & Application Implementation Effi-
ciency
When developers want to write an application that involves hardware access, they
have to study the specifications to write the drivers. This is a time-consuming job and
requires lots of expertise.
Advantech has done all the hard work for our customers with the release of a suite of
APIs (Application Programming Interfaces), called the
Secured & Unified Smart
Interface (SUSI).
SUSI provides not only the underlying drivers required but also a rich set of user-
friendly, intelligent and integrated interfaces, which speeds development, enhances
security and offers add-on value for Advantech platforms. SUSI plays the role of cat-
alyst between developer and solution, and makes Advantech embedded platforms
easier and simpler to adopt and operate with customer applications.
SUSI Functions
Control

GPIO
General Purpose Input/Output is a flexible parallel interface that allows a variety of
custom connections. It supports various Digital I/O devices - input devices like but-
tons, switches, output devices such as cash drawers, LED lights etc. And, allows
users to monitor the level of signal input or set the output status to switch on/off the
device. Our API also provides Programmable GPIO which allows developers to
dynamically set the GPIO input or output status

SMBus
SMBus is the System Management Bus defined by Intel Corporation in 1995. It is
used in personal computers and servers for low-speed system management commu-
nications. Today, SMBus is used in all types of embedded systems.
The SMBus API allows a developer to interface a Windows XP or CE PC to a down-
stream embedded system environment and transfer serial messages using the
SMBus protocols, allowing multiple simultaneous device control.
