4.3.2.4 The VGA Control API
There are two kinds of VGA control APIs, backlight on/off control and brightness con-
trol. Backlight on/off control allows a developer to turn on or off the backlight, and to
control brightness smoothly.
4.3.2.5 The Watchdog API
A watchdog timer (abbreviated as WDT) is a hardware device which triggers an
action, e.g. rebooting the system, if the system does not reset the timer within a spe-
cific period of time. The WDT API in SUSI provides developers with functions such as
starting the timer, resetting the timer, and setting the timeout value if the hardware
requires customized timeout values.
4.3.2.6 The Hardware Monitor API
The hardware monitor (abbreviated as HWM) is a system health supervision capabil-
ity achieved by placing certain I/O chips along with sensors for inspecting the target
of interests for certain condition indexes, such as fan speed, temperature and voltage
etc.
However, due to the inaccuracy among many commercially available hardware mon-
itoring chips, Advantech has developed a unique scheme for hardware monitoring -
achieved by using a dedicated micro-processor with algorithms specifically designed
to provide accurate, real-time and reliable data content; helping protect your system
in a more reliable manner
