4.1 Value-Added Software Services
Software API: An interface that defines the ways in which an application program
may request services from libraries and/or operating systems. Provides not only the
underlying drivers required but also a rich set of user-friendly, intelligent and inte-
grated interfaces, which speeds development, enhances security and offers add-on
value for Advantech platforms. It plays the role of catalyst between developer and
solution, and makes Advantech embedded platforms easier and simpler to adopt and
operate with customer applications.

GPIO
General Purpose Input/Output is a flexible parallel interface
that allows a variety of custom connections. allows users to
monitor the level of signal input or set the output status to
switch on/off the device. Our API also provide Programmable
GPIO, allows developers to dynamically set the GPIO input
or output status.
Watchdog
A watchdog timer (WDT) is a device that performs a specific
operation after a certain period of time if something goes
wrong and the system does not recover on its own. A watch-
dog timer can be programmed to perform a warm boot
(restarting the system) after a certain number of seconds.
Hardware Monitor
The Hardware Monitor (HWM) API is a system health super-
vision API that inspects certain condition indexes, such as
fan speed, temperature and voltage.
CPU Speed
Make use of Intel SpeedStep technology to reduce power
consumption. The system will automatically adjust the CPU
speed depending on the system loading.
