A
real-time O.S. in broad sense means an
operating system that very effectively
schedules the priorities of various works
and organizes the resources consumed. A good
real-time O.S. has not only quicker respond
time and higher reliability but is also
capable of restoring its system performance
after error occurrence, so that the possible
damages and loss to the system operator are
minimized. Real-time O.S. are commonly used
for industrial control, medical appliances,
traffic control and military applications.
Among various real-time O.S., the most
popular WinCE and QNX are supported by
PenMount.
WinCE is an operating system developed by
Microsoft for embedded systems. WinCE has
operating environment similar to Windows XP
but distinguishes itself by the feature to
enable users to arrange work priorities, so
that critical applications can be brought
into full play. PenMount has its full series
support WinCE 4.2/ 5.0 and the latest WinCE
6.0 R3. With PenMount, two WinCE driver
editions are provided currently, i.e. the
Standard Edition and Stylus Edition. If you
have special concern for system integration,
we recommend that you install PenMount's
WinCE driver of Stylus Edition since it
works with WinCE's built-in hand-writing
recognition and calibration feature, and
also the system-defined operation modes.
However, since WinCE's nature calibration is
a standard 4-point calibration, we recommend
that you change the calibration over to the
calibration of PenMount WinCE driver's
Standard Edition once the linearity of your
touch screen gets seriously deteriorated due
to aging. With the Standard Edition of
PenMount's WinCE driver, the advanced 4- and
9-point calibrations developed by PenMount
team are provided, which is enabled to save
the calibrated data back to the controller
and renders better touch control experience.
By the illustration below, the differences
between the driver editions that PenMounts
provided are clarified:
QNX is another popular real-time operating
system that is commonly used in industrial
control, medical devices and cars.
PenMount's full series of controllers
support the platform of QNX 6. If you are
using a PenMount 9000 or 6000 RS-232
controller, you are welcome to write us
requesting for the driver. If you are using
a PenMount 6000 USB controller, you can use
QNX's built-in HID driver directly since
PenMount 6000 USB controller is a standard
USB HID device. QNX also has a built-in
calibration program for touch screen that
supports 3- and 4-point calibration modes.
In most cases, it's 3-point calibration
algorithm can calibrate your touch screen
well.
Whether you require any additional new
functions to PenMount drivers for WinCE and
QNX platforms or you wish any PenMount
support for any other real-time O.S., you
are always welcome to contact us.
All of PenMount's touch software / hardware
series are designed meeting markets demands.
If you feel any particular requirements for
any individualized product specification, we
are ready to fully assist you in the
development. The software / hardware
