The Kionix Accelerometer Application and Firmware Development
Kit provides a simple environment to quickly begin the develop-
ment of applications and firmware that incorporate Kionix accel-
erometers. The Development Kit provides a common interface to
Kionix evaluation boards. The included software provides an easy
-to-use interface for displaying and recording acceleration data.
Plus, a graphical register map allows the user to see and change
the contents of control registers. The Silicon Labs development
board allows the use of a standard 8051 microcontroller core and
a USB interface for PC development/evaluation environments.
Additionally, the F340 Adapter Board provides a visual indication
(through an LED array) of interrupts (motion and tap) and screen
rotation output states for Kionix products that include those func-
tionalities.

Adapter Board Evaluation Board
Software
The Kionix F340
Adapter Board
provides the link
between the ac-
celerometer Eval-
uation Board and
the Silicon Labs
C8051F340-TB. Two connectors are
provided for connecting Evaluation
Boards to the Adapter Board. Evalu-
ation Boards can be plugged in di-
rectly or tethered via a ribbon cable.
The tethered connection can be
useful when evaluating screen rota-
tion, tap/double-tap, or motion
wake-up functionality since the ac-
celerometer can be more easily ma-
nipulated.
To facili-
tate proto-
type work
with Kio-
nix accel-
erometers,
Kionix has created evaluation
boards for each accelerometer
product. The evaluation boards
provide access to the pins of the
accelerometer, contain all of the
appropriate decoupling capacitors
and pull-up resistors, and allow for
easy connection into a proto-typing
system. The Development Kit ac-
commodates the KXTE9 and KXSD9
Evaluation Boards and future devic-
es that will have expanded embed-
ded functionality.
Kionix recommends the following
minimum system requirements:
Windows XP Service Pack 2
.NET Framework 2.0
USB 2.0
An installer application is provided to
aid in the setup process.
Silicon Labs
C8051F340DK
The Silicon
Labs
C8051F340-
TB provides
the micro-
processor
control and USB interfacing for the
Development Kit. As a part of the
Kit, no firmware changes are needed.

SensorCalc
SensorScope
SensorMap
This application allows the user to test and calculate the 0g offset and sensitivity
parameters of the accelerometer. Once the accelerometer is properly placed rela-
tive to the Earth’s gravity, simple mouse clicks initiate a series of test sequences
that result in the display of raw-count data.
This application allows the user to monitor data coming from the attached sen-
sor. This data can be saved to file or viewed in real time. With only two verifi-
cation steps, the application will begin immediately to display a series of
graphs representing acceleration with respect to time.
This application allows the user to read and write to specific registers on the
sensor. The registers, and their values, are all displayed simultaneously on one
color-coded grid.
Embedded Functions
Kionix is continually developing accelerometer products with embedded features. These features include the ability of
the accelerometer to indicate screen rotation state, whether or not a tap or double-tap event has occurred, and the abil-
ity to indicate activity or inactivity. This development kit can give visual indications of the tap/double-tap interrupt,
motion interrupt, and screen rotation state through a series of LED’s that are connected to several ports of the Silicon
Labs C8051F340DK.
